EVALUATION OF THE EFFICACY OF ARTHROCENTESIS USING PATIENT SPECIFIC GUIDE IN THE TREATMENT OF INTERNAL DERANGEMENT WITH REDUCTION OF TEMPOROMANDIBULAR JOINT - A COMPARATIVE STUDY.

The temporomandibular joint (TMJ) forms one of the most fascinating and complex synovial joints in the body. Temporomandibular disorders (TMDs) are defined as clinical problems involving the masticatory musculature and the TMJ associated structures or both. Treatment strategy for TMDs consists of various nonsurgical and surgical methods. Arthrocentesis of TMJ has emerged over the years as a useful technique to manage TMDs.

Arthrocentesis, a simple minimally invasive technique is generally suggested in patients irresponsive to conservative therapies. Arthrocentesis requires experienced hand and takes multiple punctures to enter the joint space with subsequent post-operative discomfort and probability for facial nerve injury.

Thus, to overcome the shortcomings of manual arthrocentesis 3d printed guides has been designed with help of ct scan. Patient with internal derangement of TMJ with reduction of disc between age of 21 to 60 years will be included in the study. Efficacy of these guides will be compared with manual arthrocentesis by comparing Time required for procedure, Number of attempts required to insert needle into superior space, Patients discomfort during procedure, Post operative pain, Maximal Mouth opening, Presence of joint sound, Postoperative complications, Cost effectiveness.
