Effect of maxillary sinus floor augmentation without bone grafts

OBJECTIVE: The objective of the present review was to determine the effectiveness of maxillary sinus floor augmentation without bone grafts using lateral window technique. MATERIALS AND METHODS: PubMed and Cochrane databases were searched for relevant articles. We also included articles by hand search until June 2012. The analysis included both human and animal studies which satisfied the following criteria: Minimum of 6 months follow-up, no use of bone grafts, and lateral window approach to the sinus. RESULTS: We included 22 articles in the review. A descriptive analysis of the constructed evidence tables indicated that there is evidence of predictable a mount of bone formation in the maxillary sinus augmentation without the use of bone grafts. CONCLUSION: Within the limits of the articles and data available, maxillary sinus augmentation without bone graft might be considered effective inpredictable bone formation.
