MJ 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.

Inclusion criteria

  • TMJ internal derangement with reduction.
  • Both genders.

Exclusion criteria

Treatment and study plan

Motor irrigation with 80% power

Other

ten patients with TMJ internal derangement with reduction using dental implant motor irrigation pump in power 80%

Motor irrigation with 40% power

Other

ten patients with TMJ internal derangement with reduction using dental implant motor irrigation pump in power 40%

conventional TMJ arthrocentesis

Other

ten patients with TMJ internal derangement using conventional technique

Primary outcomes

  1. 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) .

  2. 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

Secondary outcomes

  1. 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)

  2. change in mandibular movements

    Time frame: baseline, 1 week, 3 months

    Patient's TMJ Lateral, protrusive and side to side movements will be measured
