Brief Summary:
The aim of the present prospective randomized controlled study is to clinically and histologically investigate the safety and efficacy of bony wall repositioning compared to rotary window preparation with membrane coverage in maxillary sinus floor augmentation.
Detailed Description:
40 patients were randomly divided in two study groups after radiological and clinical evaluation. Both groups received bone grafting by a xenogeneic bone substitute (BSM, cerabone, botiss biomaterials GmbH, Zossen, Germany) using the lateral approach. In the bony wall group (BW), following piezosurgery the retrieved bony wall was repositioned. In the collagen membrane group (CM), the lateral window was created by rotary instruments, covered via a native collagen membrane (collprotect, botiss biomaterials GmbH, Zossen, Germany). After 6 months, biopsies were taken to analyze both approaches in terms of new bone formation. Duration of treatment, the number of perforations, postoperative patient discomfort were registered. Established histopathological analysis and histomorphometrical measurements to analyze the tissue reactions and the tissue distribution, i.e., the fractions of newly formed bone tissue (NB), of remaining bone substitute material (BSM) and connective tissue (CT), were conducted.
