Abstract

The centric relation bite registration tool is a tool for recording the centric relation of a patient's mandible in order to obtain proper occlusion to fabricate a full mouth fixed dental prosthesis. The centric relation bite registration tool includes both a vertically adjustable portion and a horizontally adjustable portion. The vertically adjustable portion is adapted for mounting in a dental implant in the patient's mandibular arch, and the horizontally adjustable portion is adapted for mounting in a dental implant in the patient's maxillary arch. The vertically adjustable portion and the horizontally adjustable portion are releasably secured to one another between the mandibular and maxillary arches providing a single tool which is both horizontally and vertically adjustable for recordation of the proper occlusion between the patient's mandible and maxilla.

First claim

We claim:

1. A centric relation bite registration tool, comprising:
a vertically adjustable portion; including:
a main body portion having opposed first and second ends, the main body portion further including vertical and horizontal passages therethrough;
a first base portion, a first engaging peg projecting outwardly from the first base portion and adapted for removable mounting in a dental implant in a patient's mandibular arch, the first base portion being mounted on the second end of the main body portion;
a vertically adjustable post, the vertically adjustable post being selectively vertically adjustable with respect to the main body portion via sliding action through the vertical passage, the vertically adjustable post having a free end and a fixed end, the fixed end thereof being housed within the main body portion of said vertically adjustable portion, the free end thereof projecting outwardly from the first end of the main body portion;
a spring-biased button mounted in the horizontal passage in the main body portion, the spring-biased button having a recess configured and dimensioned to receive the vertically adjustable post therein, the spring-biased button defining a release for securing the vertically adjustable post at a fixed vertical height with respect to the main body portion of said vertically adjustable portion; and
a horizontally adjustable portion, including:
a frame having opposed closed and open ends;
a second base portion, a second engaging peg projecting outwardly from the second base portion and adapted for removable mounting in a dental implant in the patient's maxillary arch, the second base portion being mounted on the closed end of the frame;
a sliding member received within the frame of said horizontally adjustable portion, wherein the sliding member is selectively horizontally adjustable with respect to the frame, further wherein the sliding member of said horizontally adjustable portion has opposed free and fixed ends, the fixed end thereof being mounted within the frame, the free end thereof projecting through a horizontally extending slot formed through the frame;
means for releasably securing the sliding member in a fixed horizontal position with respect to the frame;
a mount secured to a central portion of the sliding member, the mount having a recess defined therein for releasably receiving the free end of the vertically adjustable post of the vertically adjustable portion, wherein the free end of the vertically adjustable post engages the mount through the open end of the frame.

2. The centric relation bite registration tool as recited in claim 1 , wherein the main body portion of said vertically adjustable portion has a substantially cylindrical contour.

3. The centric relation bite registration tool as recited in claim 2 , wherein the first base portion of said vertically adjustable portion has a substantially frustoconical contour.

4. The centric relation bite registration tool as recited in claim 1 , wherein the second base portion of said horizontally adjustable portion has a substantially frustoconical contour.

5. The centric relation bite registration tool as recited in claim 1 , wherein the free end of the sliding member is threaded for releasably engaging a nut.
