Patent ID: 8656925

Claim:
A bite block device for use with intrabuccal instruments, comprising: a generally U-shaped central body having an anterior portion, a posterior portion, an upper surface for engaging upper teeth of a patient, and a lower surface for engaging lower teeth of the patient, and a uniformly graduated height decreasing from the anterior portion to the posterior portion; a lower vestibular rim extending from an outer periphery of the lower surface of the generally U-shaped central body in an arc corresponding to outer surfaces of the lower teeth of the patient; a lower lingual rim extending from an inner periphery of the lower surface of the generally U-shaped central body in an arc corresponding to inner surfaces of the lower teeth of the patient; an upper vestibular rim extending from an outer periphery of the upper surface of the generally U-shaped central body in an arc corresponding to outer surfaces of the upper teeth of the patient; and an upper lingual rim extending from an inner periphery of the upper surface of the generally U-shaped central body in an arc corresponding to the inner surface of the upper teeth of the patient, wherein the upper surface for engaging the upper teeth, the upper vestibular rim, and the upper lingual rim are anteriorly discontinuous for a common length and having a width and a depth below lower surface of the upper teeth to form an intrabuccal instrument channel therethrough, wherein the generally U-shaped central body, the lower vestibular rim, the lower lingual rim, the upper vestibular rim, and the upper lingual rim comprise a single unitary piece.
