ABSTRACT:
A tripartite dental instrument includes a curved-trough-like lip retractor, flat-fin-like cheek retractor and a straight handle. The handle and the cheek retractor are separately connected to the lip retractor at nearby locations and are each obliquely oriented with respect to the lip retractor. The dental practitioner selectively retracts the patient's lip (upper or lower) and/or cheek (left or right) while the lip retractor cradles the patient's lip at one side of the patient's mouth. The angularities and configurations featured by the inventive dental instrument advantageously afford the dental practitioner unobstructive, noninjurious and precise manipulative adjustability of either or both the lip retraction and cheek retraction functions.
