  • the task of the physician is to measure and photograph certain visual fields and especially oral areas in a number of medical fields.
  • a special task then arises If such activities are to be standardized and reproducible, even over longer periods of time
  • a typical example from the medical field is, for example, the esthetic evaluation of the dento-gingival complex around dental implants
  • the object of the present invention is to provide for standardized and reproducible measurements and photographs of the facial area and in particular of the intraoral area, particularly preferably of the dentogingival area.
  • the device should enable the parameters of the patient position, ie of the head, the camera position and optionally a mirror positioning standardized and reproducible provided
  • the device and procedure proposed according to the invention is advantageous, in particular, when variable processes occur very slowly in the observed region.
  • variable processes For example, inflammatory processes with gingival recession around implants can proceed very slowly, and the monitoring of such processes and also the documentation thereof The process must proceed according to standardized and exact criteria
  • the present invention is primarily characterized in that a device is provided, which has a Schadelhalterung for the head of the patient and an adjustable mount for a camera or a surveying device is preferably additionally a holder for a in the oral cavity of the patient Imposable mirror provided when taking pictures or measurements in the posterior region
  • the devices for the guidance of the camera and the mirror can be fixed in any position of the three-dimensional positioning, preferably with quick-release fasteners and by attached scaling also reproducible
  • the reproducibility of the various head, camera and mirror positions is an essential aspect.
  • the camera and mirror positioning units are two independent modules. Thus, e.g. For recording in the so-called anterior region to be dispensed with the mirror module.
  • FIG. 1 shows the device according to the invention in a first embodiment variant with a subject.
  • Figure 2 shows the same device in a slightly enlarged oblique view.
  • FIG. 3 is a front view of a second embodiment, and
  • FIG. 4 shows the device according to FIG. 3 with an attached subject, wherein the head holder is somewhat modified from that of FIG. Fig. 5 shows a further embodiment of the mirror holder.
  • the device according to FIGS. 1 and 2 has a base plate 4 to which all other components of the device are fastened. With a corresponding weight, the device can be easily placed on a table, with preferably non-slip elements such. Rubber feet can improve the grip. Instead of the base plate, the parts of the device can also be connected directly to a table.
  • the chin rest 11 can be moved upwards or downwards, with a measuring scale 14 being provided on a side edge of the skull holder 1 the set height of the chin rest 11 can be read and reproduced at any time.
  • the skull abutment surface 12 is adapted to rest against the forehead.
  • the contact surface can also refer to other headboards.
  • a vertical column 9 is provided for the positioning of the camera 5, whose pedestal 15 is displaceable on a curved guide rail 16.
  • the guide rail 16 is semicircular and the circle center is the intersection of the circle plane with a vertical straight line passing through the intraoral area of the subject. This ensures that, when the camera position is displaced along the curved guide rail, the focusing point of the camera 5 always lies in the mouth area of the subject when the recording area is in the mouth area.
  • a horizontal support arm 19 is arranged, on which the camera 5 is attached via a stand tube 20.
  • the holding arm 19 may be provided with a longitudinal slot 21, so that the camera position can be moved in their distance to the receiving area.
  • this position along the slot 21 is scaled and therefore definable.
  • the position of the pillar base 15 along the guide rail 16 can be read on a measuring scale 23.
  • a scaled vertical column 8 is provided as part of the mirror holder 3.
  • a horizontal support arm 24 is slidably provided, at the end of a mounting head 25 is arranged with the mirror 6.
  • a quick locking locking lever 26, 27 are provided.
  • the mirror mount is mounted with its pedestal 28 transversely to the receiving object slidably.
  • a transversely arranged mirror guide rail 29 is provided, which consists of two parallel rods according to Figures 1 and 2. The position can be queried and set via the measuring scale 30.
  • a locking lever 31 is also provided here.
  • the curved guide rail 16 serves both for fastening and guiding the camera mount 2 and the mirror mount 3.
  • the mirror guide rail and guide rail are therefore a single rail with the corresponding measuring scale 23.
  • a scaled rotary head 17 At the upper end of the vertical column 9 of the camera mount is a scaled rotary head 17 and a locking lever 18, with the horizontal arm 19 can be determined in a defined rotational position.
  • the camera 5 On the holding arm 19, the camera 5 is seated on a stand tube 20. Further locking levers are designated 37.
  • the scaled vertical column 8 for the mirror holder sits on a scaled rotary knob 35.
  • the skull abutment surface 12 can be adapted to the measurement conditions.
  • an end abutment surface is provided which laterally comprises the head with lateral arms 32.
  • the linkage 33 is shaped so that the operation is facilitated. This allows the patient to operate the cheek retractors 36 necessary for cheek restraint in the correct position.
  • cheek holders are constructed so that the mirror is positioned intraorally in a recess of the cheek retractor in the patient's mouth. In this way, the jaw pressure of the patient does not have to be intercepted via the mirror and thus the mirror positioning device, but can be leveled by the patient himself by means of the cheek retractor held by him.
  • the skull holder is placed over the chin rest 11. This can be individually adapted to the patient and easily exchangeable by means of magnetic plates.
  • the patient assumes a sitting position and positions his chin in the chin rest 11 and the other corresponding part of the skull on the skull abutment surface 12. Since the chin rest 11 are adjusted according to the patient size can, the assumed position on the scale 14 of the head rest 1 can be read.
  • the camera is brought into both the height and in the correct position along the circular arc guide rail 16 in the correct position, either on the measuring scale 23, the value is read and recorded, or the camera is brought to this position along the measuring scale as was the case with previous shots.
  • the mirror mount will have to be used. This is especially the case when recordings in the side tooth area are necessary.
  • the mirror can also fulfill a cheek restraint function or be combined with a cheek stripper (see FIG. 4).
  • the mirror can be positioned three-dimensionally in a few manipulation steps and the position can be read off.
  • the mounting head 25 may preferably be scaled about the tubular support arm 24 rotated, so that the set rotational position of the mirror is readable and reproducible.
  • FIG. 5 shows an advantageous variant of the device according to the invention, in which the mirror mount 3 carrying the mirror 6 is fastened or fastened to the camera 5 or to the camera mount 2.
  • the mirror holder the previously described vertical column for the mirror with the associated parts such as the mirror guide rail 29 omitted.
  • the device it is also possible for the device to be embodied in principle, as shown in FIGS. 1 to 4, but the mirror holder according to FIG. 5 is used. In any case, the device parts for the skull holder and the camera holder according to FIGS. 1 to 4 are necessary.
  • the mirror mount 3 is fastened to the objective 22 of the camera 5.
  • the mirror holder 3 is variable in its length in that it has two mutually displaceable and lockable by screws 40 support portions 34.
  • the screws 40 are guided in longitudinal slots 41 of the support portions 34.
  • a measuring scale 23 is provided on one of the surfaces of the mirror holder 3, wherein in the illustrated embodiment the measuring scale is on the outer surface of the mirror holder 3 is indicated. By these measures, the distance of the mirror to the lens can be adjusted and reproduced later.
  • the mirror holder 3 may have a support 39 supported on the outer lens ring 38 of the camera.
  • the advantage of this variant of the invention is that the number of parts required for standardization is reduced. Simultaneously with the camera setting, the mirror adjustment can be carried out, whereby the handling of the device is facilitated.
