MJ Arthrocentesis Using the Dental Implant Motor Irrigation Pump and the Conventional Technique in Treatment of Internal Derangement

November 16, 2025 updated by: Alexandria University

Comparison Between TMJ Arthrocentesis Using the Dental Implant Motor Irrigation Pump and the Conventional Technique in Treatment of Internal Derangement

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in pain scores
Time Frame: 1 week, 4 weeks, 3 months
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
Time Frame: baseline, 1 week, 4 weeks, 3 months
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 Outcome Measures

Outcome Measure
Measure Description
Time Frame
post operative edema
Time Frame: 1 week

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)
1 week
change in mandibular movements
Time Frame: baseline, 1 week, 3 months
Patient's TMJ Lateral, protrusive and side to side movements will be measured
baseline, 1 week, 3 months
