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.

Highlights

The application of osseointegrated dental implants has being increasingly used for functional and esthetic rehabilitation of partially or completely edentulous patients [1]
Resorption and bone remodeling in this region can result in pneumatization of the maxillary sinus
In order to determine the potential cause of the pneumatization within the maxillary sinus graft reported in this case, various factors influencing the success of bone remodeling must be considered

Summary

Background

The application of osseointegrated dental implants has being increasingly used for functional and esthetic rehabilitation of partially or completely edentulous patients [1]. To ensure eligibility for this type of procedure, the patient must exhibit a sufficient amount of bone in the region to be reconstructed This is because insufficient bone height or thickness contraindicates the rehabilitation of patients using implants [2]. The analysis of the digital examination revealed that both the left and right maxillary sinuses were pneumatized and that the anterior region had an extremely thin flange making implant surgery impossible owing to reduced bone thickness (Fig. 1a). Mineralized granular bovine bone was administered on the left side (OrthoGen, Baumer, Mogi-Mirim, São Paulo, Brazil), which was mixed with physiological saline and compressed (Fig. 1b, c), and postoperative care were passed to the patient. After another bone grafting, seven implants were performed in the patient's maxilla for her prosthetic rehabilitation (Fig. 4b)
