Allogeneic Bone Graft for Stability of Inverted L Osteotomy Mandibular Ramus

Abstract

In corrections of dent facial deformities where the mandible is the problem, the inverted 'L' osteotomy may be a good option in specific cases, such as large mandibular advancements, condylar alterations, reoperations of the mandible, to increase the posterior facial height, among other situations. This technique was not much-used because the procedure used to be performed extra orally, leaving undesirable scars. We will describe the use of the technique via intraoral access, with allogeneic grafts and use of rigid internal fixation, exemplifying with some clinical cases.
