382 elevaciones de seno con técnica de ventana lateral y uso de biomaterial de relleno

Abstract

Background Since the studies of Boyne and James research and then Tatum, maxillary sinus floor augmentation and grafting has become a standard procedure for dental implants in cases where the bone height in posterior maxilla it was insufficient. Although autogenous graft is considered the gold standard, there is currently a large amount of biomaterials which avoid the problems of autogenous bone grafts. One of the most used biomaterials is deproteinised bovine bone mineral matrix in granules (Bio- Oss ®). Objective The purpose of this study is to report our experience after 382 sinus augmentations with a lateral window approach and Bio-Oss ® graft. Material and Methods The clinical records from 382 patients having posterior maxillary atrophy treated with lateral approach sinus floor augmentation, Bio-Oss ® material graft and simultaneous or delayed dental implants. The technique used and short- term postoperative results were reviewed. Results A total of 382 patients were treated (of which 340 were done in a single phase and 42 in two phases) during the period from October 2004 to January 2010. A total of 726 implants were made, of which 27 (3.7%) failed. Conclusions Our study shows that maxillary sinus augmentation with Bio-Oss ® and lateral window approach seems to be a reliable technique with predictable long-term results.
