Definitions
- the present invention relates to the dental field and it relates, more particularly, to prostheses of the fixed or joint type, such as bridges, crowns, abutments, implants or non-removable.
- French patent 2,536,654 has thus described a process for producing a dental prosthesis consisting, firstly, of grasping the shape of the implantation area, by impression, micropalpage or optical impression, then, secondly, to machine, automatically, the prosthetic part, taking into account the data entered and the information provided by a processing software.
- the cap and the cap are selected from a stock of caps and caps which are matched so that the outer face of the cap has the same profile as the inner face of the cap.
- This document describes, in particular, a second alternative embodiment consisting, from an input of the shapes made in the mouth, to carry out, in a metal block, the machining of the internal and external faces of the metal yoke, to make a new gripping of the external face of the metal crown, to be carried out as a function of this and from a ceramic block, the machining of the internal face of the cap, then, according to the envelope and the occlusion, the machining of the external face of this before proceeding to the assembly of the metal cover with the ceramic cover.
- the object of the invention therefore aims to propose a method for producing a dental prosthesis, designed to make it possible to define the profile of the cap and of a cap taking account, respectively, of the area implantation and the environment of the prosthesis while guaranteeing an optimization of the profile of the cap to guarantee compliance with the criteria of mechanical strength and aesthetics of the cap.
- the method according to the invention is adapted to allow the production of a dental prosthesis comprising at least, on the one hand, a prosthetic cap intended to be adapted on an implantation area of the human body and, d on the other hand, a prosthetic cap worn by the cap.
- the method consists in carrying out the following steps:
- the method according to the invention therefore has the advantage of allowing the definition of a cap taking into account the anatomical profile of the implantation area, the external surface of the cap and the criteria for producing the cap, in view obtain a reliable prosthesis over time.
- the object of the invention also has the advantage of making it possible to determine, without requiring the manufacture of a prosthesis and from clinical information, whether it is possible to produce the cap and the cap under acceptable conditions of reliability and aesthetics. Such a method thus offers the possibility of choosing and adapting the profile of the cap according to the conditions of production of the cap.
- Figure 1 is a schematic view illustrating the adaptation of a prosthesis on a tooth to be fitted
- Figures 2 to 4 are schematic views each showing a characteristic step of the method according to the invention.
- FIG. 5 is a view showing in perspective the stage of the process carried out in FIG. 4;
- Figures 6 and 7 are sectional and perspective views illustrating another step of the method according to the invention;
- Figure 8 is a perspective showing an exemplary embodiment of a representation of a prosthesis to be produced
- Figure 9 is a sectional view illustrating another step of the method according to the invention.
- Figures 10 and 1 1 illustrate embodiments of the elements of a prosthesis, obtained according to the method according to the invention
- FIG. 1 shows an example of a tooth to be fitted 1 by means of a prosthesis 2 according to the invention, comprising a prosthetic coping coping 3 on which a prosthetic coping 4 is mounted.
- the tooth to be fitted 1 has an implantation zone 5 for the prosthesis 2, constituted, in the example illustrated, by a stump.
- the part of the human body serving as implantation zone 5 can have a different shape, such as in particular a cavity, or even an absence of stump (pontic).
- the method according to the invention consists in producing, by means of a molding 6, an imprint of at least the implantation zone 5.
- the mold 6 is made of any way known to those skilled in the art, with a view to obtaining at least one profile representative of the implantation zone 5, namely the stump in the example illustrated.
- This step of the process therefore aims to collect, by one or more molding operations and possible clinical and / or morphological measurements (mandibular kinematics, smile line, 7), information relating to implantation and integration of the prosthesis inside the patient's mouth.
- the method according to the invention provides for establishing a three-dimensional digitized representation R., of at least the implantation area 5.
- the digitized representation R of the implantation area which is illustrated in FIG. 3, is obtained from a sensor, preferably of an optical nature enabling measurements of the molded impression 6 to be taken, with a view to obtaining the definition, in three dimensions, of the area d implantation 5. It must be considered that the measurements can be taken directly on the negative impression made by the mold 6 of profile complementary to that of the stump, or on a positive mold reproducing the stump and obtained from the negative mold 6.
- the sensor used transmits the measurements, after conversion, to a computer which records the three-dimensional digital data characterizing the implantation area 5.
- the computer which is equipped with a screen, is adapted to ensure the visualization of a three-dimensional representation R of the implantation area 5.
- a digital representation such as for example R 1a , R 1b for the adjacent and / or antagonistic teeth.
- the method according to the invention then consists in defining a digital three-dimensional representation R 1 c of the internal surface of the prosthesis defined from the digital representation R of the implantation area, taking into account the rules related to the insertion and sealing of a prosthesis.
- provision may be made to leave, in particular, a space between the digital representation R., of the implantation area and the digital representation R 1 c of the internal surface of the prosthesis for placing the cement,
- the method according to the invention then consists in defining a digital three-dimensional representation R 2 of the external surface of the prosthesis, from environmental parameters of the prosthesis and of the digital three-dimensional representation R 1c of the internal surface of the prosthesis.
- the digital representation R 2 makes it possible to visualize the external surface of the prosthesis in relation to the digital representation R., of the implantation area 5 and, possibly, representations of the teeth adjacent and / or antagonistic, such as, for example, R-
- the external surface of the prosthesis is therefore determined on the basis of any measurements made on the molded impression and a statistically representative or acceptable morphology of the prosthesis to be produced, on which laws of deformation are applied based on clinical criteria accepted by one skilled in the art. For example, provision may be made to use the criteria as defined in dental anatomy courses. It should be noted that the volume between the surface R 1 c and the surface R 2 is representative of the total volume of the prosthesis.
- the object of the invention then consists in determining a three-dimensional digitized representation R 3 of the external surface of the prosthetic coping 3, from the digital representation R 1c , of the internal surface of the prosthesis and of the representation R 2 of the external surface of the prosthesis.
- the digitized representation R 3 of the external surface of the yoke is produced taking into account the criteria which must be respected for the definition of the cap 4 which corresponds to the volume comprised between the representations R 3 and R 2 .
- the criteria to be respected are, for example, the rules related to the aesthetics or to the shape and to the minimum and / or maximum thickness that the cap must present according to the nature of the material used. .
- the method according to the invention also has the advantage of knowing whether, before proceeding with the manufacture of the prosthesis, it is possible to produce a prosthesis which respects the anatomical requirements of the oral environment and the mechanical and aesthetic constraints linked to the production of the prosthesis.
- it can provision should be made to make a digital representation of the prosthesis 2 from the digital representations R 2 , R 3 , respectively of the external surface of the prosthesis and the external surface of the yoke.
- the digital representation R 3 of the external surface of the yoke is ensured by appropriate programming means taking into account the digital representations R 1c R 2 respectively of the internal surface of the prosthesis and the external surface of the prosthesis and the manufacturing criteria of the cap previously recorded. It should be noted that the volume between the surface R 1c and the surface R 3 is representative of the total volume of the screed.
- the method according to the invention consists in also defining a three-dimensional digitized representation R 4a . of the inner surface of the cap defined from the digitized representation R 3 of the outer surface of the cap taking into account the rules related to the insertion and sealing of a cap on a cap.
- provision may be made to leave, in particular, a space between the digital representation R a . of the internal surface of the cap and the digitized representation R 3 of the external surface of the cap for the installation of the sealing cement.
- the method according to the invention then consists in defining a three-dimensional digitized representation R 4 of the external surface of the cap defined from the digital representation R 2 of the external surface of the prosthesis and of the external limit of the digital representation R 4a of the internal surface of the cap.
- the volume between the surface R 4a . and the surface R 4 is representative of the total volume of the cap.
- the digital representations R Aa . and R A are obtained using appropriate programming means.
- the point cloud corresponding to the three-dimensional digital representation R 3 of the external surface of the yoke and the point cloud corresponding to the three-dimensional digital representation R 1c , of the internal surface of the prosthesis are delivered to any installation capable to exploit digital information, such as a numerically controlled machine.
- a corresponding prosthetic cap 4 can be machined (FIG. 11).
- the point cloud corresponding to the three-dimensional digital representation R 4a . of the internal surface of the cap and the point cloud corresponding to the three-dimensional digital representation R 4 of the external surface of the cap are delivered to any installation capable of exploiting the digital information
- the definition of the yoke 3, according to the method according to the invention, makes it possible to optimize its production, both from the mechanical point of view, and from the aesthetic point of view.
- the clevis 3 can thus have an internal anatomical profile respecting the clinical information, but also an external profile complying with the criteria, in particular, of mechanical and aesthetic behavior for the production of the cap 4.
- such a method makes it possible to automatically compensate for the defects of the implantation zone, by making it possible to produce a digitized representation R 3 of the external surface of the screed which adapts to the morphology of the zone of implantation while giving the cap 4 a constant thickness.
- Another advantage of the method according to the invention is that it allows either to choose the machining parameters as a function of the constraints linked to the surfaces to be machined, or to adapt the profile of the surfaces to be machined according to the mode of machining. .
- the prosthesis consists of two separate parts, namely a yoke 3 and a cap 4. It should be noted that the method according to the invention can be implemented for a prosthesis not comprising two separate rooms. Thus, it can be envisaged to determine a three-dimensional digitized representation R 3 of the external surface of the coping, so that it is, at least locally, undersized relative to the external surface of the prosthesis determined by the representation 3D digitized R2.
- This addition of material is constitutive of the cap and is, in general, worked or machined, in order to impart the final aesthetic appearance to the prosthesis.
- the prosthetic coping 3 produced from this digital representation, has an at least localized excess thickness, which is then worked by removing material to constitute the final prosthetic coping.
- the prosthetic cap and the prosthetic cap form a single piece.
- the method according to the invention has been described in relation to the manufacture of a prosthesis relating to a single tooth. It must, of course, be considered that the method according to the invention can be implemented for a plural prosthesis. In this case, it should be noted that the different steps of the method according to the invention can be implemented to ensure the realization, one after the other, of the various teeth of the plural prosthesis. Likewise, each step of the process can be applied to all of the teeth of the prosthesis.
