Pneumatization within a maxillary sinus graft: a case report

Viviane Rozeira Crivellaro et al. Int J Implant Dent. 2016 Dec.

Abstract

Rehabilitation of edentulous posterior maxilla with implant-supported prostheses frequently presents a challenge to dentists. This is due to insufficient bone within the region, in addition to other limiting factors such as anatomical pneumatization of the maxillary sinus. Thus, grafting of the maxillary sinus is a common procedure used to counteract these problems. Regardless of the type of biomaterial used, the success of the procedure is dependent on the formation of high-quality bone. Therefore, vascularization is a key factor for successful grafting and for the long-term maintenance of the treatment. This paper reports a clinical case of bone graft pneumatization and attempts to elucidate its potential etiology.

Keywords: Angiogenesis; Bone graft vascularization; Maxillary sinus; Pneumatization.
