About this study

This study were performed on eight patients to evaluate the accuracy of virtual planning of the custom planning alloplastic TMJ replacement surgery

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients have a history of end-stage TMJ disorders.
  • Patients with mandibular defects involving the TMJ,developmental abnormalities, trauma and, tumor.
  • Patients with failed grafts and alloplastic joint reconstruction.
  • Patients with recurrent TMJ ankylosis.

Exclusion criteria

  • Patients with bone disease that can affect stability of the joint.
  • Patients with systemic disease, malignancy and immunocompromised patients.

Treatment and study plan

Custom made TMJ

Device

Patients with end stage TMJ disorders, Tumors, Recurrent ankylosis, traumaof failed previous joint reconstruction had TMJ total Replacement using custom made TMJ via Virtual planning

Primary outcomes

  1. Accuracy of the Virtually planned TMJ

    Time frame: 3 days postoperative

    superimposition of the postoperative and preoperative instructions using CT calculating Linear deviation (mm) to assess surgical accuracy.

Secondary outcomes

  1. effect of artificial joint on electromyographic activity of masticatory muscle

    Time frame: 3 months following up

    was measured using electromyograph. the parameters were measured through recording Muscle activity during maximum voluntary clenching and at rest.

  2. occlusal force

    Time frame: 3 months following up

    occlusal force and distribution during clenching using B scan device. Parameters including Maximum occlusal force (%)
