Computer guided buccal cortical plate separation was performed for ten patients using patient specific osteotomy locating guides and pre-bent plates. The guide was designed to outline the osteotomy, buccal cortical plate was separated, the lesion was removed, finally the pre-bent plates were used to fix the separated cortex.

Inclusion Criteria:

• Patients with well-defined radiopaque lesion affecting angle region, its conventional removal may compromise the bone continuity and leads to pathological fracture indicating the need of buccal cortical plate separation technique

Exclusion Criteria:

• Patients with any medical condition contraindicating the surgical procedures were excluded
