Detailed explanation-1: -Disc displacement with reduction (DDWR) is one of the most common intra-articular disorders of the temporomandibular joint (TMJ). Factors related to the etiology, progression and treatment of such condition is still a subject of discussion.
Detailed explanation-2: -Disk displacement with reduction typically manifests with clicking/popping and pain with jaw use (such as chewing). Disk displacement without reduction does not manifest with clicking/popping, but maximum jaw opening is limited to ≤ 30 mm. Surrounding tissues may become painfully inflamed (capsulitis).
Detailed explanation-3: -The anterior disc displacement without reduction is a benign and self-limiting condition. The first line of treatment is mandibular manipulation to recapture the displaced disc. If mandibular manipulation is successful, the patient should be provided with an occlusal appliance.
