Brief Summary

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.

Conditions

TMJ Disorder

Outcome Measures

Primary Outcomes (2)

• Change in pain scores

  a 10 point visual analogue scale (VAS)\*. (0-1=none, 2-4=mild, 5-7=moderate, 8-10=severe) .

  1 week, 4 weeks, 3 months

• Change in mouth opening

  The patient's maximum mouth opening (MMO) value will be measured by taking the average of three consecutive measurements of the distance between the maxilla and mandible mid-central incisive teeth with the Endo ruler after the patients were asked to open

  baseline, 1 week, 4 weeks, 3 months

Secondary Outcomes (2)

• post operative edema

  1 week

• change in mandibular movements

  baseline, 1 week, 3 months
