Brief summary

This study will evaluate the patient specific surgical stent and plate for guided reduction and fixation of mandibular angle fractures.

Detailed description

14 Patients were allocated into 2 groups: Group A underwent reduction using a patient-specific surgical reduction guide generated through virtual surgical planning, whereas Group B underwent conventional manual reduction Follow-up extended to 12 weeks. Clinical parameters included pain, operative time, postoperative occlusion, wound healing and mouth opening. Radiographic evaluation was conducted using computed tomography scans acquired preoperatively and postoperatively ,superimposition of the pre and postoperative models will be done to create error map and measure the accuracy

Masking description

Patients were allocated in a 1:1 ratio using an on-site computer software system with concealed allocation through sequentially numbered, opaque, sealed envelopes (SNOSE). Group A (Guided Reduction Group): fracture reduction performed using a patient-specific surgical reduction guide derived from virtual surgical planning. Group B (Manual Reduction Group): fracture reduction performed using conventional intraoperative manual techniques without a reduction guide.
