Objectives: Twenty years after Summers’ first description of the transalveolar osteotome technique in the posterior maxilla, this procedure is the standard method for sinus floor elevation. Minimal post-operative morbidity, reduced treatment time and lower patient expenses are some of the advantages over the more invasive lateral window approach. The aim of this study was to retrospectively evaluate screw-type implants with simultaneous sinus augmentation placed between 2002 and 2008. Methods: Screw-type implants (n = 45) were placed in molar sites with reduced bone height using the osteotome technique with simultaneous augmentation and deproteinised bovine bone mineral (DBBMc). After a minimum healing time of 12 weeks, implants were loaded with single cemented (porcelain-fused-to-metal) crowns. All patients were followed up clinically and radiographically for more than 5 years. Results: Of the 45 implants, 3 (6.6%) were lost and 37 (82.2%) were in “optimum functional and aesthetic condition”. All implant sites with functioning fixtures showed complete radiographic opacity in the formerly augmented sinus areas. Bone height increased significantly (p Conclusion: Transalveolar sinus floor elevation using graft material leads to successful functional and aesthetic long-term outcomes.
