[Pre-implantation bone graft coffering technique for posterior mandibular edentulism: between onlay grafting and regeneration].

Background: Pre-implant placement posterior mandibular bone grafts remain a challenge for maxillofacial surgeons. We present a coffering technique we prefer using in this localization.

Surgical Procedure: This original technique involves creating a sagittal mandibular groove in which a graft harvested from the retromolar region is wedged vertically, after being sharpened in a bone mill.
