TEMPOROMANDIBULAR DISORDER
Twenty participants of group I (the control group) received MAD. The upper and lower arch impressions were recorded in irreversible hydrocolloid impression material (DPI Algitex) and the cast was poured in dental stone (Kalabhai). Using a George Gauge, the protrusion index was calculated for all study participants by extending the jaw to 60–80% of its maximal protrusion (roughly 6 mm). The upper and bottom halves of the device were made of acrylic, and they were joined by moving the mandible 6mm forward from its central location. Symptoms related to temporomandibular disorder (TMD) were assessed but none of the study group participants had any complaints related to it. All the patients were counseled to wear the appliance during sleeping for a minimum of 6 h daily.MAD placed intra-orallyCMOA
