Installation of reconstruction plate and ilican crest bone graft in a pseudoartrosis area after anterior vertical osteotomy in the mandible: case report

Abstract

Introduction: The anterior vertical osteotomy of the mandible is an extremely versatile procedure and can be used in selected cases in which orthodontic mechanics have their limitations. On the other hand, there are studies that demonstrate that the complications of this procedure include pseudoarthrosis, neuropraxia, the possibility of periodontal problems and the fact that this technique is not always useful. Case report: The objective of this study is to report the case of a patient who underwent surgery for anterior vertical osteotomy of the mandible in 2002, evolving without bone integration and with mandibular mobility for years, presenting as the main complaint, gingival retraction. Being proposed in 2018, a surgical re-approach, with the use of iliac crest graft and reconstruction plate. Final considerations: It is concluded that the use of autogenous bone graft, associated with reduction and fixation with reconstruction plates, are considered positive for the treatment of pseudoarthrosis, and can be considered as an option during surgical treatment.
