## Abstract

The bite registration block is used for recording the relation between a patient's maxillary and mandibular arches for proper fabrication of a fixed dental prosthesis, or prostheses, such as fixed crowns or the like. The bite registration block is particularly adapted for use when a patient's prepared teeth are opposed by an edentulous arch (i.e., opposed by an area of missing teeth). The bite registration block is formed from a resilient material, such as a suitable type of plastic or the like, and is formed as a block having opposed upper and lower surfaces, a pair of laterally opposed side surfaces, and a pair of longitudinally opposed side surfaces. The upper surface defines a concave, longitudinally extending recess for positioning about an edentulous region of the patient's jaw.

## Claims

### Claim 1

A bite registration block, comprising:
a block, the block consisting of opposed upper and lower surfaces, a pair of laterally opposed smooth continuous, uninterrupted side surfaces, and a pair of longitudinally opposed side surfaces, wherein only the upper surface defines a longitudinally extending recess for positioning about an edentulous region of a patient's jaw, the longitudinally extending recess extending continuously along the upper surface from one longitudinally opposed side surface to the other and being defined by a pair of opposed, sloped flat surfaces terminating at a central, laterally extending planar surface extending parallel to the lower surface of the block, and at least one of the upper and lower surface is textured for frictionally engaging a respective piece of bite registration material, wherein at least one of the longitudinally opposed side surfaces includes a recess and further comprising a dental clasp, the dental clasp having an end portion engaging the recess thereby being attached to the block.

### Claim 2

A bite registration kit, comprising:
at least one piece of bite registration material; and
a bite registration block, the bite registration block comprising a block formed from resilient material, the block consisting of opposed upper and lower surfaces, a pair of laterally opposed continuous, uninterrupted side surfaces, and a pair of longitudinally opposed side surfaces, wherein only the upper surface defines a longitudinally extending recess for positioning about an edentulous region of a patient's jaw, the longitudinally extending recess extending continuously along the upper surface from one longitudinally opposed side surface to the other and being defined by a pair of opposed, sloped flat surfaces terminating at a central, laterally extending planar surface extending parallel to the lower surface of the block, wherein at least one of the longitudinally opposed side surfaces includes a recess and further comprising a dental clasp, the dental clasp having an end portion engaging the recess thereby being attached to the block.

### Claim 3 (depends on 2)

The bite registration kit as recited in claim 2, wherein the at least one piece of bite registration material comprises a pair of pieces of bite registration material.

### Claim 4 (depends on 3)

The bite registration kit as recited in claim 3, wherein each of the upper and lower surfaces is textured for frictionally engaging a respective one of the pieces of bite registration material.
