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.

Change in pain scores
a 10 point visual analogue scale (VAS)\*. (0-1=none, 2-4=mild, 5-7=moderate, 8-10=severe) .
Time frame: 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
Time frame: baseline, 1 week, 4 weeks, 3 months
post operative edema
Scales: * None (no swelling) * Mild (intra oral swelling confined to surgical field) * Moderate (extra oral swelling in the surgical zone) * Severe (extra oral swelling spreading beyond the surgical zone)
Time frame: 1 week
change in mandibular movements
Patient's TMJ Lateral, protrusive and side to side movements will be measured
Time frame: baseline, 1 week, 3 months
