Platelet-Rich Plasma for Bone Healing in Maxillary and Mandibular Fractures

The goal of this clinical trial is to learn if platelet-rich plasma (PRP) made from the patient's own blood helps broken jaw bones heal faster and stronger in adults with fractures of the upper jaw (maxilla) or lower jaw (mandible). The main questions it aims to answer are: * Does adding PRP during fracture surgery increase bone density at the fracture site at 6 months compared with surgery alone? * Is the effect of PRP on bone healing similar in upper jaw and lower jaw fractures? Researchers will compare patients who receive standard fracture fixation with titanium plates plus PRP to patients who receive the same fixation without PRP, to see if PRP improves bone healing. Participants will: * Give a small blood sample (12 ml) before surgery, from which PRP will be prepared (PRP group only) * Undergo surgery under general anaesthesia to fix the fracture with two titanium plates and screws * Take antibiotics and anti-inflammatory medicine for one week after surgery * Return for check-ups and a CBCT (3D dental X-ray) scan at 1 week, 3 months, and 6 months after surgery to measure bone healing
