Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy of the Virtually planned TMJ | 3 days postoperative | superimposition of the postoperative and preoperative instructions using CT calculating Linear deviation (mm) to assess surgical accuracy. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| effect of artificial joint on electromyographic activity of masticatory muscle | 3 months following up | was measured using electromyograph. the parameters were measured through recording Muscle activity during maximum voluntary clenching and at rest. |
| occlusal force | 3 months following up | occlusal force and distribution during clenching using B scan device. Parameters including Maximum occlusal force (%) |
