ABSTRACT:
A bite block where, in a first embodiment, the mouthpiece is flanked by laterally-extending arms that define large, inverted "U"-shaped finger-accommodating openings so that a surgeon may guide a surgical tool by placing fingers within those openings. The mouthpiece has a cylindrical throughbore that receives the surgical instrument. The upper and lower teeth of the patient are supported by flat upper and lower support walls that are formed integrally with the mouthpiece, and each support wall includes a retention ridge that helps keep the mouthpiece in the patient's mouth. Upper and lower flanges extend above and below the plane of their respective support walls, so that the mouthpiece cannot enter the patient's mouth even when the surgeon pulls back the patient's lips to their limit. In a second embodiment, the arms are eliminated to provide unlimited finger access, and a strap has a bifurcated section so that it can weave through upper and lower parts of the bite block to provide a fastener that ensures at least one of its ends will be accessible even when a patient's head is turned to the side on a pillow. In both embodiments, a cushioned pad overlies the mouthpiece for the comfort of edentulous patients.
