BACKGROUND Prosthetic rehabilitation of the posterior maxilla with dental implants is often difficult because of proximity to the maxillary sinus and insufficient bone height. Maxillary sinus floor augmentation procedures aim to obtain enough bone with an association between biomaterials and autogenous bone. PURPOSE The purpose of this study was to evaluate histomorphometrically two grafting ...

Objective: This first aim of this study was to determine whether there is a relationship between the presence Haller cells and Schneiderian membrane thickness (SMT) by considering factors such as age gender. The second investigate correlation visibility on cone beam computed tomography (CBCT) digital panoramic radiographs. Materials Methods: Seventy-eight edentulous patients were included in st...

The careful planning of a sinus lift procedure is the key to avoiding surgical complications. In this clinical case, female patient, 59 years old and totally edentulous in maxilla, was referred Egas Moniz’s Dental Clinic Implantology consultation with indication for bilateral external maxillary sinuses prior implant placement. Both orthopantomography cone-beam computed tomography were used show...

BACKGROUND Insufficient alveolar bone height often prevents the placement of standard dental implants in the posterior part of edentulous maxilla. In order to increase adequately the vertical dimension of the reabsorbed alveolar process, a sinus lift procedure is often necessary. The aim of this study was to evaluate histologic results of a prehydrated corticocancellous porcine bone used in max...

OBJECTIVES The aim of this study was to follow 41 intraoperative perforations of the Schneiderian membrane during sinus floor elevation and to identify potential differences from patients without perforations. MATERIAL AND METHODS Two hundred and one sinus floor elevations were performed at the department of oral and maxillofacial surgery of the University Hospital of Schleswig-Holstein in th...
