A cheek and lip retractor (30) for dentistry comprises respective cheek portions (36, 38) and lip portions for the upper and lower lips. In one embodiment, the lip portions each comprise a lip shield (32, 34) and mucosa pads (40a, 40b, 42a, 42b) that are separate and spaced apart from the lip shield (32, 34). The lip shield (32, 34) includes a first side edge (82) that is disposed within a patient's mouth, and a second side edge (84) that is disposed outside the patient's mouth, when the retractor (30) is used to separate the lips of the patient. The cheek portions (36, 38) and lip portions are connected to each other by flexible connecting elements (44, 46, 48, 50) and the connecting elements (44, 46, 48, 50) are disposed between the lip shields (32, 34) and the mucosa pads (40a, 40b, 42a, 42b). In another embodiment, the cheek portions (36, 38) of the retractor (30) include first side edges (90) disposed within a patient's mouth, and second side edges (92) disposed outside the patient's mouth during use to separate the lips of the patient. |
