Abstract
The inventive retractor includes two half-moon shaped trays at each side located on the sides of the mouth covering the lips and opening the mouth to reveal the teeth from the front. The trays are interconnected by a strap-like member spacing the upper and lower teeth from one another by a slight amount. The angulation between the trays and the strap-like member is devised to improve the patient's comfort level and to better facilitate alignment of the retractor with typical human oral anatomy. Each of the inventive trays has a handle so that the retractor may easily be gripped for insertion into the mouth and removal therefrom.
