Definitions

• Registration unit for determining the bite position
• base plates on the upper and lower jaw models made according to the functional impression are provided with wax walls, which are aligned in the mouth of the patient on the occlusal plane, the vertical jaw relationship from the resting limb, reduced by 2 to 3 mm goes.
• the upper and lower jaw wax walls are fused together.
• the registration in the desired terminal hinge axis position can only be reached approximately with this method and also the support pin registration by recording the arrow angle, eg.
• the most precise method for determining the bite position in the form practiced today, is due to the essential error that the manufactured base plates are made on the functional models, but neither here nor in the mouth of the patient guarantee a precise fit.
• the invention relates to a multi-membered cutlery thatjans ⁇ footprint, Handbiß casserole and support pin bite registration in a step Schu ⁇ summarizes'. It saves the patient and dentist from two appointments, allows them to work more quickly and delivers more precise results.
• the registration device (according to the invention) is characterized in that an individual JDberkiefer impression tray (Fig.1.1) is prepared in front of the impression by three, with internally threaded sleeves (Fig.2.1), which with the help of an assembly aid plate (Fig .1.2) and corresponding screws with screw heads that are flat with the plate (Fig.2.2) are placed in parallel and polymerized with plastic * (Fig.2.3), the retention pins of the respective sleeves (Fig.2.) Are shortened accordingly, and the mounting aid plate is indicated is set in "parallelism to the occlusal plane.
• a screw (Fig.2.6) can now be screwed into each sleeve, which is available in variable lengths and is characterized in that instead of a normal screw head after conical tapering (Fig.2.7) it has a second, smaller thread (Fig.2.8 ), which is selected in its length so that the protruding part can accommodate a fixation nut (Fig.2.) after placing the registration plate on the cone portion.
• the functional impression is repositioned in the patient's mouth and the modified bite fork (Fig. 5.) with its oral portion (Fig.5.1), which contains holes (Fig.5.2), identical to the registration plate, on the cone portions of the screwed in.
• the bite fork is placed on the Bipupillarline and the Camper ' see plane adjusted, whereby the parallelism to the Bipupillar ⁇ line is made by changing the distal screws, then parallelism to the Camper's plane is made by turning the anterior screw. Changing all three screws identically lowers or lifts the bite fork into the occlusal plane.
• the bite fork is removed and, if the screw position is identical, the registration plate is attached after removal of the maxillary function impression and fastened with the fixation nuts.
• the pen (FigJ.l) for recording the arrow angle is mounted in the middle of a metal plate (FigJ.2), which has two rows of drill holes (Fig.3.3) and can hold the pens (Fig ⁇ .l). These also have a retention part (Fig.4.2) and a flat support surface (Fig.4.3) is attached between the pin and the retention part.
• the fixation of the pins on the plate is released, the individual mandibular tray being prepared for the functional impression (Fig. 4).
• a modified pen plate with a three-point support on the individual lower jaw spoon is also conceivable for the lower jaw.
• the maxillary functional impression with the attached registration plate is placed in the patient's mouth.
• the pen plate with the selected holes is placed on the pens on the also reduced functional impression of the lower jaw.
• the height of the pen is changed so that the distance between the extraoral marking points on the patient is 2 to 3 mm below the resting position.
• the registration plate is typically color-marked with a bold pencil and after repositioning the arrow angle is recorded (Fig.7.1).
• the stylus plate is replaced by a second one (Fig. 3.4).
• the holes for the retention pins are identical to those of the first plate.
• the position of the pen is also identical to that of the first plate, so that after the pen height has been adjusted by the patient, the arrow angle obtained can be traced exactly.
• the second pen plate After being placed on the functional impression in the anterior area, the second pen plate extends beyond the alveolus ridge and shows an exactly linear boundary (Fig. .5). This allows a precisely worked wedge with a flat surface to be placed caudally on the writing surface (Fig.7.2), with its inclined plane linearly touching the straight boundary of the pen surface in the anterior portion (Fig.6.1).
• a pad in the cranial part of the registration plate, z. B. also designed as a magnet, shifted to modify the lip fullness and marked with the reference lines, center line, canine line and smile line.
• the upper jaw is articulated with the help of the transfer sheet, while the registry is used to articulate the lower jaw. Finally, the functional impressions are subtracted from the plaster after the reference lines have been tapped from the pad and placed on the plaster after the bite fork has been placed on it.
• the registration set contains the screws for changing the registration plate in different sizes in order to take into account the individuality of the respective intraoral conditions.
