Background: Millions of individuals worldwide suffer from temporomandibular joint (TMJ) disorders and are characterized by pain and joint dysfunction. TMJ internal derangement (ID) is the most frequent type of temporomandibular disorders (TMDs). TMJ arthrocentesis represents a form of minimally invasive surgical treatment in patients suffering from internal derangement of the TMJ Aim of the study: To clinically compare between the effect of TMJ arthrocentesis under high hydraulic pressure by dental implant motor and the conventional method in treatment of TMJ internal derangement regarding pain and mandibular movements.
