Definitions
- the object of this invention is a new apparatus which is suitable for recording in the mouth the position of the dental arches in relation to the condylar axis and for reproducing this same position in the technician's lab.
- the field of the invention in question is that of the equipments or devices that are used, in dentistry and dental technique, for the fabrication of dental restorations at large.
- the conventional devices described above show a fixed connection between the metal plate and the occlusal plane. Their main feature is that they are made in one single piece.
- the dentist has to have as many complete facebows in the dental office as are the measurements that have to be done. On the contrary, it would be easier to always use the same occlusal plane and to replace on this plane only the metal plate.
- the dental technician for his part, needs to transfer the whole equipment to the laboratory, but has to face problems of volume and dimensions and runs the risk that - because of shocks or other reasons - the correct position of the metal plate in relation to the occlusal plane might be lost during transportation (due to the articulated connection between these parts).
- the face-bow After being transferred to the technician's lab, the face-bow has to be mounted in an articulator that has to be compatible with the face-bow itself. For this reason the dental technician needs to have in the laboratory all possible different combinations of articulators and face-bows, with evident problems of costs and working troubles. In fact, if there should be something wrong with the equipment or for any other reason, the replacement of the face-bow has to correspond to the replacement of the articulator, if the face-bow is of a different kind compared to the previous one and vice versa.
- the main purpose of this invention is to offer a new apparatus for recording and reproducing the position of the dental arch in relation to the condylar axis.
- This apparatus in comparison to the usual facebows, is easier and more practical to use and is also compatible with all different kinds of articulators in commerce.
- the apparatus according to this invention makes it possible to separate the metal plate from the occlusal plane, anyway without losing the record taken on the position of the dental arch in relation to the condylar axis. In this way it is no longer necessary to have as many complete sets of instruments as are the restorations to be fabricated. Moreover the dental technician can take only the metal plate to the laboratory and leave the occlusal plane in the dental office. Thus the space and the volume occupied by the transported device is considerably reduced and above all there isn't any risk that the records that the dentist has taken in the mouth might be modified during transportation.
- This invention also allows the dentist to register the data on the position of the dental arch. These registrations can be kept and re-used, thus avoiding the conventional need for taking the measurements again, even for the same face anatomy, if more restorations are fabricated at different times.
- the apparatus of this invention is universal and can be used with all different articulators used by dental technicians.
- picture 1 shows in perspective the apparatus according to this invention, that has been broken down into its' main parts;
- picture la shows the equipment of picture 1 seen from A;

- the apparatus according to the invention shown in picture 1 , is made up of the following main parts:
- the parts that are used by the dentist to record the position of the dental arch are shown in pictures 2 to 5.
- the metal plate 1 is provided, on its anterior portion 31 (picture 5), with an articulated attachment head 2 to the corresponding' female seat 4 which is located at the end of a graduated rod 3.
- This in turn is suitable for sliding, with its end opposite to the one supporting plate 1, into a seat 6 provided in a support 42 of the occlusal plane 5.
- rod 3 has a polygonal structure or shows protuberances that prevent its rotation insided the above-mentioned seat 6.
- the occlusal plane 5 has a basically U-shaped structure, that shows, on its transversal arm or bottom 32, the above-described seat 6 for rod 3.
- the lateral arms 33, 34 of plane 5, on the contrary, show some fulcrums that are identified by hollow seats, 7 and 8 respectively. These fulcrums in turn are suitable for housing the graduated sliding rod 35 of the corresponding goniometers 10.
- a suitable thickness of wax is applied (not illustrated in the picture) and is then introduced into the patient's mouth, so that it can receive the impression of the dental arch.
- the articulated head of rod 3 is connected to its female seat 4 of portion 31 of the metal plate 1 that protrudes out of the mouth.
- the occlusal plane 5 is oriented with the lateral arms 33 and 34 placed beside the ears (picture 6), by introducing at the same time rod 3 into its seat 6 on the same occlusal plane 5.
- the fulcrums 7 and 8 are brought to the level of the patient's condylar axis 36 (pictures 6 and 8), at the same time lining up with the bipupillary plane 43.
- the dentist definitely locks head 2 in its seat 4: thus the position of the metal plate 1 is fixed in relation to the graduated rod 3. At this point he tries to achieve the alignment of fulcrums 7 and 8 on the condylar axis 36, by having rod 3 slide into seat 6 of the occlusal plane 5.
- goniometer 10 is fabricated out of a clear material, so that the angular position of point 14 can be read on the goniometer itself.
- the dental technician who has to fabricate the restoration receives the metal plate 1 that is rigidly fixed on the rod 3, together with the values L, H, ⁇ that have been recorded on the patient by means of the above-described device.
- the metal plate 1- graduated rod 3- assembly is now transferred on the equipment parts that are illustrated in pictures 9 to 12.
- These include a base 1 1 , that basically reproduces the shape and functions of the occlusal plane 5 and that shows a seat 17 in which a sliding graduated rod 18 is housed, that is perpendicular to the (usually horizontal) plane, containing the base 1 1 itself.
- rod 18, like rod 3 has a shape or shows some protuberances that prevent the rotation around its axis, after being housed in the mentioned seat 17.
- rod 18 has a graduated scale 19, on which the height H can be read, that has been previously measured with goniometer 10 (picture 1 1).
- a seat 20 On the end of rod 18 that is in the opposite position compared to the end that is engaged in the mentioned seat 17, a seat 20 is built that houses, like seat 6 of the occlusal plane 5, the sliding graduated rod 3, on which the metal plate 1 is fixed. The operator has rod 3 slide into this seat 20 until the length L that has been previously recorded on the patient can be read on the graduated scale. A screw 41 serves for locking rod 3 in this position.
- one goniometer 21 is fixed on each side.
- a hollow seat 22 that coincides with the notch 13 of goniometers 10 defines the position of the condylar axis 36.
- the sliding pins or condylar rods 23 and 24 are housed (picture 10) that can be locked, in relation to goniometers 21 , by means of screws 25 and 26.
- the end of the pins 23, 24, that is external to goniometers 21, is provided with a knob 27 for the manual hold of the pins themselves.
- a jaw-shaped articulator 29 (picture 10) is clamped between the ends 28 of pins 23 and
- the articulator 29, at this point, can be rotated until the angle ⁇ , that had been previously recorded on the patient, can be read on goniometers 21.
- ⁇ that had been previously recorded on the patient
- goniometers 21 For a better illustration of this angle, in pictures 1 and 9 only the plane taken by articulator 29 has been illustrated. By means of a incisal rod 30 this angulation can be maintained during the following working steps.
- the metal plate that is now carrying the stone model can be kept, together with the measurements of L, H, and ⁇ and be recorded, in order to be used again for the fabrication of new restorations, at different times, for the same patient.
- the apparatus according to this invention is used by clamping plate 1 between the dental arches.
- the horizontal arm 48 is lined up with the bipupillary plane 43 and the vertical arm 47 is lined up with the middle line 52 of the patient's face.
- the position L of rod 3 that corresponds to the correct centering of plate 1 in relation to the dental arch, the position L of rod 3, the distance H of the notch 13 of goniometer 10 from the occlusal plane and the inclination , in relation to the occlusal plane, of the straight line 38 that joins the mentioned notch 13 (defining the position of the condylar axis) and the point 14 that is located in the lower portion of the eye 15 are read (picture 16).
- the rod 3 is taken out of the occlusal plane and used for building the stone model of the teeth.
- plate 1 is connected to rod 3 by means of an articulated joint, combined with two pre-fracture arms 49 and 50, that are placed sideways on joint 2.
- two pre-fracture arms 49 and 50 that are placed sideways on joint 2.
- this plane 5 can be supplied with a suitable water level (not illustrated).
- the supporting device of articulator 29 is provided, on base 1 1 , with an arm 46 that carries one hinged end of the articulator itself.
- the opposite end of this articulator shows, in a position that is adjustable through the fastening screw " 47, the mentioned incisal rod 30, that is suitable for resting, with its lower end, on the sliding bearing plane 48 of the graduated rod 18.
- the inclination ⁇ of the articulator 29 is also selected. This inclination is read directly on the graduated scale 49 provided on the mentioned bearing plane 48 for the incisal rod 30 on the graduated rod 18. In this way it is possible to reproduce in the laboratory the position of the dental arches, by directly reading the angle on the graduated rod 18 and with no need for the goniometers 21 that are present according to the manufacturing version of picture 9.
