Hypothesis The investigators hypothesis that fixation of mandibular angle fractures using a 3D titanium miniplate will provide better occlusal bite force than intraoral fixation using the standard two-plate technique. The investigators expect that this method will facilitate a faster recovery time for participants to regain baseline occlusion force.

Fixation using two titanium miniplates. One plate at the inferior border of the mandible with bicortical screws. Second plate \~5 mm above or at the external oblique ridge with monocortical screws.
Single 2.0 mm 9-hole 3D titanium plate fixed with monocortical screws. Plate contoured with horizontal crossbars perpendicular and vertical struts parallel to fracture line. Screws placed diagonally first.

Occlusal force
use bite force measurement device . make patient bite to muser the force (, newton unit).
Time frame: first day surgery , second visit 30 days , the last visit 120 days. .
maximal incisal opening.
Ask the patient to open their mouth as wide as possible without feeling pain. Using a ruler or caliper, measure the vertical distance between the incisal edge of the upper central incisor and the incisal edge of the lower central incisor

Patient satisfaction
will be measured on a visual analogue scale (VAS) with zero being unsatisfied and ten being satisfied and happy .
