- the mobile phone is attached to the base so that less than 20%, preferably less than 15%, preferably less than 10%, preferably less than 5%, preferably less than 2% of the area of the rear face are masked by the adapter;
- the back of the mobile phone is not in contact with the adapter or the area of the contact surface between the back of the mobile phone and the adapter is less than 40%, preferably less than 30%, preferably less than 20%, preferably less than 10%, preferably less than 5% of the area of said rear face;
- the mobile phone is clamped in a clamping direction, preferably clamped perpendicular to the direction of the length or the width of the mobile phone, preferably parallel to the front face of the mobile phone, against the base of the adapter;
- the mobile phone is clamped against the base at a plurality of clamping points, the greatest distance between clamping points, measured perpendicular to the direction of clamping, preferably measured along the direction of the length of the mobile phone being greater 1 cm, preferably greater than 2 cm, preferably greater than 3 cm, preferably greater than 4 cm, and/or less than 10 cm;
- the adapter comprises at least one strap, preferably elastic, and/or at least one first jaw pressing the mobile telephone against the base;
- the adapter opening is laterally offset with respect to the tightening zone of the mobile telephone on the adapter, a lateral offset being a non-zero distance, in an offset direction perpendicular to the tightening direction and in a parallel plane in the plane of the front face of the mobile telephone, between the position of the center of the adapter opening and the position of the center of the clamping zone;
- the lateral offset is greater than 3 cm and less than 10 cm.
- the adapter in particular the base, comprises first and second jaws between which the mobile phone is clamped, in a tightening direction;
- the clamping direction is preferably perpendicular to the direction of the length of the mobile phone and/or perpendicular to the direction of the width of the mobile phone and/or along a diagonal joining two corners of the mobile phone;
- the adapter has no stop limiting movement perpendicular to the tightening direction; - the first jaw and/or the second jaw has(have) the shape of a cradle receiving the edge of the mobile telephone.
- the adapter includes:
- an elastic member for example a spring, acting on the first jaw and/or the second jaw, respectively, so as to produce a said spreading movement
- the first non-return system comprises:
- ratchet wheel mechanically coupled to the first jaw and/or the second jaw so that rotation of the ratchet wheel causes the first jaw and/or the second jaw to move relative to the base
- a first elastic member for example a spring, elastically pushing the first pawl against the ratchet wheel
- the first jaw and/or the second jaw comprises a first rack
- the adapter comprises a stepped wheel rotatably mounted on the base, and comprising
- the first jaw and/or the second jaw comprise(s) an elastically deformed pad resting on the mobile phone, the deformability of the pad allowing at least one passage between two consecutive indexed positions defined by the cooperation of the ratchet wheel and of the first pawl.
- the adapter comprises a plate movably mounted on the base and on which the spacer is rigidly fixed, removably, for example by clamping, or non-removably, for example by forming a one-piece assembly;
- the spacer is preferably mounted on the base by clipping
- the plate is slidably mounted on the base in at least one direction, preferably exclusively in a single sliding direction;
- the mobile phone is clamped on the base in a tightening direction
- the adapter includes a deactivatable lock allowing the plate to be selectively locked in position relative to the base;
- the plate is mobile on the base in an incremental manner
- the adapter includes a second deactivatable non-return system preventing a return movement of the plate relative to the base;
- the second non-return system comprises:
- a second elastic member for example a spring, elastically pushing the second pawl against the second rack;
- the acquisition opening is laterally offset with respect to the clamping area of the mobile phone on the adapter, a lateral offset being a non-zero distance, in a direction of offset perpendicular to the clamping direction and in a parallel plane in the plane of the front face of the mobile telephone, between the position of the center of the acquisition opening and the position of the center of the clamping zone;
- the lateral offset is greater than 1 cm, preferably greater than 2 cm, preferably greater than 3 cm, preferably greater than 4 cm, and/or less than 10 cm.
- the spacer can be integral with the base or the adapter can be removably attached to the spacer;
- the adapter is removably attached to the spacer, preferably the adapter has an adapter attachment part and the spacer has a cooperating spacer attachment part, in said position of acquisition, with the adapter attachment portion for securing the adapter to the spacer, the spacer attachment portion being configured to retain its shape when mated and/or uncoupled from the attachment portion adapter;
- no point of the surface of the spacer attachment part moves, during said coupling and/or said uncoupling, by more than 1 mm, preferably by more than 0.5 mm, preferably by more than 0.2mm;
- the spacer attachment part is formed by a recess and/or a bead of spacer material
- the distance between the spacer attachment part and the acquisition opening is less than 3 cm, preferably less than 2 cm, preferably less than 1 cm, preferably less than 0.5 cm.

- a “clear" surface of the screen 20 is a surface that is not covered by the adapter 26. If a part of the adapter 26 made of a transparent material, for example a transparent strap, covers a surface of the screen, this surface is not considered “clear”.
- the adapter 26 is preferably configured to, in the assembled position, leave clear more than 80%, preferably more than 90%, preferably more than 95%, preferably substantially 100% of the surface of the screen 20 of the cellphone.
- the surface of the adapter 26 which is in contact with the mobile telephone 12 in the assembled position is called the “contact surface”.
- more than 70%, more than 80%, preferably more than 90%, preferably substantially 100% of the contact surface is in contact on the front face 12i and the edge 22 of the mobile telephone, preferably on the song 22 of the mobile phone.

- the contact surface does not cross the screen 20 from one edge of the rear face 12 2 to an opposite edge of the rear face 12 2 .
- the contact surface does not cross the screen vertically.
- the mobile telephone in the assembled position, is not surrounded by the adapter 26, as is the case when a strap or a flap rests on the rear face to compress the mobile telephone against a face of receiving adapter 26.
- a surface of the screen 20 "visible” is a surface which is not covered by the adapter 26 or which is covered by a transparent part of the adapter, so that it is possible to see the screen at through. If a part of the adapter 26 made of a transparent material, for example a transparent strap, covers a surface of the screen, this surface is therefore considered to be “visible”. Preferably, tactile communication with the screen is possible through said parts of the adapter 26 made of a transparent material. A surface of the screen 20 which is not “visible” is said to be “masked”.
- the adapter 26 is preferably configured to, in the assembled position, leave visible more than 80%, preferably more than 90%, preferably more than 95%, preferably substantially 100% of the surface of the screen 20 of the cellphone.
- the screen 20 thus makes it possible to perfectly observe the teeth.

- the first jaw is movably mounted on the base 50.
- the second jaw is immobile relative to the base.
- the mechanism for bringing the jaws together and then locking them in position is thereby simplified and made more compact.
- the gain in compactness is particularly useful for a kit according to the invention, which must allow the use of the lens of the mobile telephone arranged on the front face of the telephone.
- the immobility of the second jaw also makes it possible to position the mobile phone in its final position before the two jaws are brought together to tighten the mobile phone.
- the operation of fixing the mobile phone is considerably simplified, in particular because it is not necessary to hold the mobile phone while the approximation of the jaws.
- the maximum distance ds2 between the first and second jaws is preferably greater than 5 cm, preferably greater than 7 cm, preferably greater than 9 cm, and/or less than 25 cm, preferably less at 15 cm (figure 3).
- the minimum distance ds2 between the first and second jaws is preferably greater than 2 cm, preferably greater than 3 cm, preferably greater than 5 cm, and/or less than 10 cm, preferably less at 8cm.
- the bringing together of the first jaw of the second jaw, or “movement of coming together”, leads to the assembled position, generally intermediate between the close and separated positions, in which the first and second jaws grip and clamp the mobile telephone 12, preferably by pressing on edge 22 of the mobile phone.
- the first jaw 521 is preferably mounted to move in translation relative to the second jaw, in a clamping direction Z52, preferably vertical in the service position.
- the first jaw 52i is mounted elastically movable in translation relative to the second jaw 52 2 , in the clamping direction.
- the adapter 26 comprises an elastically deformable member, preferably a spring 56, preferably a compression spring, arranged so as to oppose a thrust of the first jaw 521 towards the close position.
- the spring 56 is arranged in a housing of the base 50 and extending vertically. It is compressed between the bottom of the housing and the first jaw 521.
- the adapter 26 may comprise several springs 56 arranged in respective housings extending vertically and compressed between the bottom of their respective housing and the first jaw 52i.
- the risk of overhang is reduced.
- the adapter 26 includes a single spring 56, preferably a compression spring, which extends along the tightening direction, halfway across the first and second jaws 52i and 52 2 .
- the compactness is advantageously improved.
- the second jaw 52 2 can be movable on the base 50.
- the base 50 preferably incorporates the second jaw, as shown in Figure 3 (in Figure 4, the second jaw has been removed from the base 50).
- Figure 4B in side view, at least one of the first and second jaws, preferably each of the first and second jaws has the shape of a gutter, or "cradle shape", which extends along the direction Y52 and which, in the assembled position, receives the mobile phone 12.
- the first and second jaws thus come not only to clamp the mobile telephone, but also to retain it by complementarity of form.
- the holding of the cell phone 12 is thereby improved.
- the gutter shape also promotes sliding of the mobile phone between the first and second jaws, parallel to the direction Y52. Such sliding makes it possible to arrange the lens 16 so that the optical axis Xi 6 is in the vertical plane containing the axis X a of the adapter opening Oa.
- the base 50 comprises a receiving face 54, preferably flat, preferably vertical, on which the mobile telephone rests in the assembled position.
- This flat surface is preferably defined by a pad 58 made of elastomer. It preferably extends to the second jaw.
- the support of the mobile phone on the receiving face 54 contributes to its maintenance, in particular by limiting the slippage between the first and second jaws.
- the mobility of the mobile phone 12 positioned between the first and second jaws is not limited by abutment, which makes it possible to position a mobile phone of any length.
- At least the first jaw 52i is mounted incrementally movable on the base 50.
- the adapter 26 comprises a deactivatable first non-return system preventing a separation movement of the first jaw, that is to say a movement opposed to a movement of approximation.
- the first non-return system preferably comprises, as illustrated in Figures 4 and 5:
- ratchet wheel 64 rotatably mounted around an axis X ⁇ 4, on the base 50, cooperating with the first pawl 62, and mechanically coupled to the first jaw 52i so that a rotation of the ratchet wheel 64 causes the first jaw to move parallel to the clamping direction Z52, and - A first spring 66 elastically pushing the first pawl 62 against the teeth of the ratchet wheel 64 so as to allow rotation of the ratchet wheel 64 only in the direction of rotation producing a closing movement.
- the successive positions of the first jaw during a translation in the clamping direction Z52 are marked by the elastic penetration of the first pawl 62 between the successive teeth of the ratchet wheel 64.
- the coupling of the ratchet wheel 64 and the first jaw 521 can be provided with a rack and pinion assembly.
- the first jaw 52i is provided with a first rack 68 extending parallel to the tightening direction and the adapter 26 comprises a stepped wheel 70 mounted for rotation, around the axis X ⁇ 4, on the base 50, and comprising
- pinion 72 coaxial with the ratchet wheel 64, cooperating with the first rack 68 so that a rotation of the pinion 72 causes a displacement of the first jaw parallel to the tightening direction.
- such a stepped wheel is particularly compact and allows incremental and well-controlled movement of the first jaw.
- the adapter 26 preferably includes a first push button 74 on which pressing causes the deactivation of the first non-return system.
- first pawl 62 is coupled to first push button 74 such that actuation of the push button (by pressing the push button) causes first pawl 62 to disengage from the ratchet wheel.
- the first push button 74 and the first pawl 62 are each at one end of a rocker 76 mounted for rotation about the axis Xr,2. Pressing the first push button 74 therefore causes a rotation of the rocker 76 and the disengagement of the first pawl 62 from the teeth of the ratchet wheel 64, that is to say a deactivation of the first non-return system.
- the cessation of this support causes a rotation in the opposite direction, under the action of the first spring 66, and the engagement of the first pawl 62 between the teeth of the ratchet wheel 64.
- the first non-return system thus forms a lock to selectively block in position or release the movement of the first jaw 521 on the base 50.
- the first jaw 52i is preferably mounted on the base 50 so as to move away elastically from the second jaw.
- the deactivation of the first anti-return system therefore causes an elastic return to a separated position.
- an elastic return of the first jaw 521 towards the separated position considerably facilitates the mounting of the mobile telephone 12 on the adapter 26.
- each of the first and second jaws comprises a buffer 78 made of an elastomer which, in the assembled position, bears against the mobile telephone 12.
- the buffer 78 is configured so that, when the first jaw is incrementally movable on the base 50 and the buffer 78 begins to clamp the mobile telephone, its elastic deformation makes it possible to reach the next indexed position.
- the clamping of the mobile phone makes it possible to effectively clamp the phone, without damaging it.
- Buffer 78 also contributes to the protection of the mobile telephone against shocks and vibrations.
- the clamping zone 71 by which the mobile telephone 12 is clamped by the first and second jaws is exclusively defined by pads 78.
- the clamping zone 71 is constituted by a set of clamping points. At each of these points, the adapter exerts a so-called "tightening" compression force on the mobile telephone 12.
- the greatest distance between the tightening points, measured along the direction of the length Lu of the mobile telephone, is preferably greater than 1 cm, preferably greater than 2 cm, greater than 3 cm, and/or less than 20 cm, preferably less than 10 cm, preferably less than 8 cm, preferably less than 6 cm, preferably less than 5 cm.
- At least one “elementary” tightening zone (that is to say the part of the tightening zone defined by a jaw), preferably each elementary tightening zone, has an overall length L52 greater than 1 cm, preferably greater than 2 cm, greater than 3 cm, and/or less than 20 cm, preferably less than 10 cm, preferably less than 8 cm, preferably less than 6 cm, preferably less than 5 cm.
- length outside all means the greatest distance between two points of the elementary tightening zone, in the direction Y52.
- the overall length is not modified if the elementary tightening zone is locally interrupted between these two points.
- the overall length L52 is the greatest distance between clamping points.
- the attachment of the mobile phone 12 to the adapter 26 is particularly stable.
- the kit can thus be manipulated by holding the phone, which facilitates the acquisition of data through the lens 16 of the mobile phone.
- the elementary clamping zone of the first jaw and/or of the second jaw preferably extends along the length of the mobile telephone.
- the adapter 26 further comprises a plate 80 defining the adapter opening Oa and movably mounted on the base 50, preferably at least in translation, preferably at least parallel to a vertical sliding direction Zso, preferably exclusively parallel to the sliding direction Zso.
- Sliding can be achieved by means of a slider, for example carried by plate 80, slidably mounted in a rail formed in base 50. Sliding by means of several sliders slidably mounted in respective parallel rails can be achieved to limit the risk of overhang.
- the position of the adapter opening Oa relative to the lens 16 can thus be modified.
- the mobility of the plate 80 on the base 50 is independent of the mobility of the first jaw on the base 50, and more generally independent of the position of the mobile phone 12 on the adapter 26.
- the mobile phone 12 is fixed rigidly on the plate 80 by clamping between the first and second jaws, in a removable manner.
- the position of the mobile phone 12 relative to the adapter opening Oa can therefore be adjusted independently horizontally by sliding between the first and second jaws, and vertically, by sliding the plate 80 on the base 50, up to position the lens 16 facing the adapter opening Oa, preferably substantially in the center of the adapter opening Oa.
- the adapter aperture Oa is preferably sized so that, at least in this centered position of the lens 16, the flash 18 faces the adapter aperture Oa.
- the flash 18 can thus illuminate the teeth during the acquisition of 2D or 3D data by the mobile telephone 12.
- the plate 80 is preferably mounted incrementally movable on the base 50. In other words, at least in one direction, it can be moved in steps, preferably in constant steps.
- the adjustment of the position of the adapter opening Oa relative to the mobile telephone is thereby facilitated.
- the adapter 26 comprises a deactivatable lock making it possible to selectively block the plate 80 in position with respect to the base 50.
- the base 50 comprises a second rack 82 and the plate 80 comprises
- a second pawl 84 mounted for rotation, around an axis Xg4, on the plate 80, so as to cooperate with the teeth of the second rack 82,
- a second spring 86 elastically pushing the second pawl 84 against the teeth of the second rack 82 so as to define indexed positions to position the plate 80 along the second rack 82. These successive indexed positions are marked by the elastic penetration of the second pawl 84 between the successive teeth of the second rack 82.
- the second rack 82 and the second pawl 84 are shaped to allow a translation of the plate 80 only in one direction, namely, in Figures 6 and 7, the direction of the rise.
- the second rack 82 and the second pawl 84 then define a second deactivatable non-return system preventing a return movement, in this case a downward movement of the plate 80 with respect to the base 50.
- the adapter 26 preferably includes a second push button 94 on which pressing causes the deactivation of the second non-return system.
- the second pawl 84 is coupled to the second push button 94 so that actuation (by pressing the second push button 94) causes the release of the second pawl 84 from the second rack 82.
- the second push button 94 and the second pawl 84 are each at one end of a rocker 96 mounted for rotation about the axis Xs4.
- Pressing the second push button 94 therefore causes a rotation of the rocker 96 and the disengagement of the second pawl 84 from the teeth of the second rack 82, that is to say a deactivation of the second non-return system.
- the cessation of this support causes rotation in the opposite direction, under the action of the second spring 86, and the engagement of the second pawl 84 between the teeth of the second rack 82.
- the second non-return system thus forms a lock to selectively lock in position or release the movement of plate 80 on base 50.
- the second rack 82 could be on the plate 80 and the second pawl 84 be mounted on the base 50.
- a mark made on the adapter, indicates possible positions of the mobile telephone 12 with respect to the base 50 and/or of the plate 80 with respect to the base 50, for example depending type or brand of mobile phone.
- the mark may for example be an arrow associated with a brand of mobile telephone.
- the plate 80 includes a first mark and the base includes one or more second marks opposite which the first mark can be positioned, or, equivalently, the base 50 includes a first mark and the plate 80 includes a or several second markers in front of which the first marker can be positioned.
- the second marks correspond to mobile phone brands. In other words, to correctly position a mobile phone on the support, it suffices to position the first marker opposite the second marker corresponding to the brand of this mobile phone.
- the acquisition opening Oa' is laterally offset with respect to the clamping zone of the portable telephone 12 on the adapter 26, as represented in FIG. 6B.
- the lateral offset is determined by observing the adapter 26 from the front, that is to say parallel to the axis of the acquisition aperture Oa' (FIG. 6B).
- the vertical planes P1 and P2 delimit the clamping zone.
- the Y offset direction is the horizontal direction, parallel to the plane of the front face of the mobile phone.
- the positions p a' and p s of the center Ca' of the acquisition aperture Oa' and of the center Cs of the clamping zone, respectively, can be identified.
- the distance di, along the offset direction Y, measures the lateral offset (FIG. 6B).
- the lateral offset is constant.
- the lateral offset is greater than 1 cm, preferably greater than 1 cm, preferably greater than 3 cm, or even greater than 4 cm, or greater than 5 cm, and/or and less than 10 cm.
- the lateral shift allows the acquisition aperture Oa′ to be positioned facing the lens 16 and allows the mobile phone to be well fixed on the adapter 26 even if the lens 16 is very close to an edge of the front face.
- This attachment is particularly effective because the clamping area can be substantially halfway along the mobile phone 12 while the acquisition opening or the adapter opening is close to the side edge of the mobile phone 12.
- the mobile phone is clamped by its two large sides and held horizontally for the acquisition of images or 3D models, as illustrated in Figure 6.
- the lateral offset allows not only to balance the kit, with a tightening preferably approximately at mid-length, but also to facilitate access to the buttons of the mobile phone which, following the direction of the length of the mobile phone, are at the level of the lens 16 , that is, in the upper part of the mobile phone.
- the kit follows directly from the preceding description. Initially, the kit is in the disassembled position. If necessary, G user chooses a spacer 24 among several spacers, according to the personalization mark 39.
- the clipping results from the attachment of the claws of the adapter in the recesses made on the outer surface of the spacer 24.
- the spacer After clipping, the spacer extends substantially as far as the adapter opening Oa defined by this housing. It thus defines a jacket which limits the contact of the wall defining this housing with the air breathed in service.
- the distance ds2 between the first and second jaws is then greater than the width of the mobile telephone 12.
- the user places the mobile telephone 12 on the pad 58, resting on the second jaws 52 2 , then moves it laterally, along of the second jaw, until the adapter opening Oa is substantially in line with the lens 16, that is to say above or below the lens 16.
- the lateral offset of the first and second jaws with respect to the adapter opening makes it possible to achieve this position without substantially offsetting the tightening with respect to the middle of the length of the mobile telephone.
- the user pushes the first jaw back until it comes into contact with the edge of the mobile phone, so as to take it in a vice with the second jaw.
- the first rack 68 drives the pinion 72, and therefore the stepped wheel 70 and the ratchet wheel 64.
- the first pawl 62 pushed by the first spring 66, engages the ratchet wheel 64 and prevents any spreading movement of the first and second jaws. It also allows incremental movement of the first jaw, i.e.
- the mobile phone 12 is then fixed rigidly on the base 50, clamped between the first and second jaws. Screen 20 is clear.
- the second pawl 84 pushed by the second spring 86, engages the teeth of the second rack 82 and prevents any downward movement of the plate 80. It allows incremental movement of the stage 80.
- the user presses the second push button 94 to disengage the second pawl 84 from the second rack 82. He can then lower the plate 80. As soon as he releases the second push button 94, the pawl engages the second rack 82 again, under the effect of the second spring 86.
- the kit in the acquisition position, is ready for use.
- the spacer does not prevent the user's jaws from coming together or moving apart. It thus authorizes the acquisition, in particular of photos representing the teeth of the user, while the user has his mouth open or his mouth closed, keeping the lips turned up. By rotating the kit around him, the user allows the mobile phone to observe different regions of his mouth, for example to take pictures of the dental arch or the teeth at the back of the mouth.
- G user takes 2D or 3D data for at least a front view, a right view and a left view.
- G user takes 2D or 3D data for at least one open mouth view and at least one closed mouth view, preferably each time for front, right and left views.
- the user can then analyze the acquired data and/or transmit them with the mobile telephone 12.
- the user finally separates the spacer 24 from the adapter 26 by pulling hard enough on the spacer to disengage the claws 38.
- the spacer needs to be cleaned or even sterilized.
- it does not include any moving part whose operation might be affected by these operations.
- the order of operations can be changed.
- the user can attach the spacer to the adapter before or after attaching the mobile phone.
- the dismantling of the spacer can be earlier or later than that of the mobile phone.
- the invention considerably facilitates the acquisition of photos or 3D models, including representing the vestibular surfaces of molars, in particular for the implementation of the method described in PCT/EP2015/074896. It allows rapid acquisition, under excellent hygienic conditions, typically in less than a minute, without having to resort to a specialized person, in particular a dentist or an orthodontist.
- the acquisition can in particular be carried out by the user himself or by one of his relatives, with a simple mobile phone, anywhere, and in particular outside a medical, dental or orthodontic practice.
- acquisition is possible without using a tool resting on the ground to immobilize the mobile telephone, and in particular without a tripod.
- the kit allows a quick and reliable fixing of the mobile phone, whatever its thickness, without risk of damaging it.
- the shape of the spacer is not limiting.
- the second jaw can be mobile, and optionally mounted on the base like the first jaw.
- the first jaw 52i is movably mounted on the base 50 so as to elastically approach the second jaw.
- the first anti-return system can then be designed to prevent this approach, its deactivation causing an elastic return to a close position.
