This study assessed the efficacy, safety, and technical feasibility of inducing bone formation in an animal model of maxillary sinus floor augmentation using recombinant human bone morphogenetic protein-2 (rhBMP-2) impregnated on an absorbable collagen sponge (ACS). Bilateral antral maxillary sinus floor elevation procedures were surgically performed in six adult female Alpine-Saanen goats. Bon...

PURPOSE An-organic bovine bone graft is a xenograft with the potential of bone formation. The aim of this study was to evaluate the bone density using cone beam computed tomography scans around functional endosseous implant in the region of both augmented maxillary sinus with the an-organic bovine bone graft and the alveolar bone over which the graft was placed to provide space for the implants...

Background: Considering the growing interest in dental implants to replace missing teeth and the subsequent increase in sinus augmentation surgery, one of the anatomical landmarks that may be injured during this procedure is the posterior superior alveolar artery (PSAA).The purpose of this study was to evaluate thelocation of PSAAusing cone beam computed tomography (CBCT) scans. Methods:160 CBC...

PURPOSE This study aimed to evaluate the effectiveness of the modified sinus floor elevation technique described hereafter as a "hybrid technique," in 11 patients with severely resorbed posterior maxillae. METHODS Eleven patients who received 22 implants in the maxillary premolar and molar areas by the hybrid technique were enrolled in this study. A slot-shaped osteotomy for access was prepar...

BACKGROUND The purpose of the present study was the clinical and the histologic evaluation of fresh frozen human bone (FFB) allografts used for maxillary sinus-augmentation procedures. METHODS Ten subjects were treated with maxillary sinus augmentations using FFB. Radiologic measurements were recorded on computed tomography scans preoperatively and 5 months after the sinus surgeries. At 5 mon...

Due to the close anatomical relationship of the maxillary sinuses to the dentoalveolar complex, surgical procedures involving these anatomical structures represent a part of a everyday practice in oral surgery and implantology. Those interventions are directed mainly towards the treatment of odontogenic infections of the sinuses as well as surgical treatment of oroantral fistulae and odontogeni...
