Abstract:	In the posterior maxilla the residual bone volume very often is not sufficient for implant placement and consecutive implant supported prosthetic treatment. Thus the technique of sinus grafting, utilizing the lateral window techique, has to be applied. The objective of this retrospective study was to evaluate frequency and type of postoperative complications and their influence upon treatment outcome.In the last ten years 397 sinus sites have been augmented consecutively. 41 (10.3%) for single tooth replacement. 247 (62.2%) for partial edentulous sites and 109 (27.5%) treating maxillary edentulous patients. 869 implants have been placed. All patients are in an least once-a-year recall routine. Data management and check-ups of patinets was achived by an independent researcher not involved in patient treatment.In 250 sites (59.7%), with bone height of less than 4 mm, two stage procedure was chosen. 147 sites (40.3%) showed sufficient bone volume for primary implant stability. 80.9% of the sites were augmented with special xenografts (Bio-Oss), 4.3% with special autografts and 14.8% with combinations of brafting materials. 62 complications involving 77 implants were subsumized in 6 different groups and 3 degrees of severity. There were 31 sites with implant failures. 4 buccal implants exposures. 15 dehiscences of oral mucosa with and without loss of augmentation material or membrane/implant exposure. 3 acute po. Infections. 9 considerable reductions of augmentation volume and 2 cases of acute late sinusitis with empyema. This means a complication rate of 15.6%. In 34 (8.6%) cases the treatment plan was not affected. 20 (5%) made necessary modification of the treatment plan and in just 8 cases (2% of all) implant supported prostheses could not be achived.Despite a raletively high incidence of postoperative complications the treatment objective of implant-supported rehabilitation of the posterior maxilla could be achived in 97.2%, including changes of the treatment plan in 8.2%. Within the limits of a retrospective study the present investigation showed implants placed in combination with sinus augmentation functioned successfully during an observation period of 10 years.
