[Stability of grafts and implants after bone grafting of the maxillary sinus. Retrospective analysis of 44 patients].

Objectives: We assessed the reliability of maxillary bone grafting and implant stability, comparing our results with reports in the literature.
Material and Methods: This retrospective series included 44 patients who underwent maxillary sinus bone grafting between 1998 and 2002. An analogous graft was used for 31 patients and a combination autologous-bone substitute graft for 13. One hundred twelve dental implants were positioned at the grafting site (2.5 implants per graft). We assessed recipient site morbidity, bone graft integration and stability, and stability of the implants.
Results: Bone grafting was successful in 97.8% of patients. There was one failure. Two of the 112 implants failed.
Discussion: Our results are comparable with those in the literature. This study demonstrated the reliability of maxillary bone grafting with equivalent results using autologous bone and combination autologous bone-bone substitute.
