Mandibular reconstruction of segmental defects is an arduous surgical procedure that requires an utmost degree of surgical fidelity. Whether primary bone reconstruction is feasible or not, alloplastic bridging between the remaining bone stumps is mandatory to achieve functional, aesthetic, and symmetrical demands of the lower third of the face. Mandibular reconstructive surgery should be directed toward the maintains of the normal orthognathic centric condylar position, mandibular kinematics, and muscles of mastication function. Mandibular resection with coronoid removal cause imbalance in the attachment of one of the large muscles of mastication, the temporalis muscle. The use of computer-aided surgery allowed the creation of custom made fixation plates with a plethora of advantages over the conventional plates. the study aims to introduce a novel plate design, which creates an enthsis for the reattachment of the temporalis muscle tendon.

Mandibular Kinematics assessment
range of mandibular excursions were recorded preoperatively (T0) and at 1-postopertive week (T1), 1-postoperative month (T2), 4-postoperative month (T3), 6- postoperative month (T4).
Time frame: 6 months
Postoperative temporalis muscle activity
surface-Electromyogram (sEMG) was used by the patients during their maximum voluntary clenching by placement of two channels on the bilateral temporalis muscles
Time frame: 6 months
