Abstract
The cheek and lip retractor for dentistry comprises respective cheek portions and lip portions for the upper and lower lip, the lip portions comprising a lip shield and mucous pads which are separate and spaced apart from the lip shield, the cheek portions and lip portions being connected to each other by flexible connecting elements, and the connecting elements being disposed between the lip shield and the mucous pad. Such a retractor allows a largely free treatment of the tooth portions to be treated and provides a comfortable fit for the patient.
