Maxillary sinus lift for single implant-supported restorations: a clinical study PURPOSE: The aim of this study was to evaluate single- tooth implant-supported restorations placed in conjunction with several methods of maxillary sinus augmentation. MATERIALS AND METHODS: A retrospective review was conducted of all consecutively treated patients who received single-implant tooth rehabilitation in combination with sinus augmentation. Implant survival rate and peri-implant condi- tions, such as marginal bone resorption (mm), pocket depth (mm), Plaque and Bleeding Indices, and Periotest values, were compared for the different augmentation procedures. RESULTS: Fifty-one patients were treated with 54 screw- type single implant-supported restorations in the posterior maxilla in combination with isolated sinus floor augmentati- on. Depending on the residual ridge height and the intended augmentation height, sinus lift elevation was performed eit- her in a 1-stage lateral approach (25 patients, 28 implants), in a 2-stage lateral approach (12 patients, 12 implants), or with the osteotome technique (14 patients, 14 implants). The predominant use of long implants provided for a favo- rable implant-crown ratio (> 1.0) and produced an overall clinical survival rate of 100% over the observation period (44.5 ± 22.7 months), with no differences between the augmentation procedures and implant types used. The most frequent site for single-tooth replacement in combination with sinus floor augmentation was the first molar region (61%). Implants with wider diameters (94% ≥ 4.3 mm) were used in this region. The most frequent intraoperative compli- cation was tearing of the sinus membrane (58%) as a result of the restricted access for the lateral 1- or 2-stage approach, and the most frequent prosthetic complication was crown loosening. CONCLUSION: On the basis of this retrospective review, the following was observed: (1) Successful function and excel- lent peri-implant parameters may be anticipated for single implant-supported restorations placed in conjunction with sinus elevation procedures. (2) Clinical and radiographic ex- aminations demonstrated similar conditions for single-tooth restorations despite the use of different surgical approaches to sinus augmentation.
