- PURPOSE. To compare the effectiveness of and patient preference for crestal versus la- teral sinus lift. MATERIALS AND METHODS. Fifteen partially edentulous patients missing bilateral maxillary molars and/or premolars and having 2 to 6 mm of residual crestal height below the maxillary sinuses were randomised to receive one to three implants placed in sinuses crestally or laterally lifted with bone substitutes according to a split-mouth design. Implants were submerged and loaded after 6 months with definitive screw-retained metal-ceramic prostheses, and patients were followed-up to 1 year after loading. RESULTS. Twenty crestal implants were placed versus 23 lateral ones. One patient drop- ped out and one lateral implant failed (n = 14; difference = 0.07, 95% CI from -0.28 to 0.13; P = 0.99). No prosthesis failed. Three patients were affected by three complications at crestal versus three patients by four complications at lateral sites. The difference was not statistically significant (n = 14; Diff = 0.07; 95% CI -0.24 to 0.38; P-value = 0.99). Statistically significantly less time was required to place crestal implants (28.2 versus 62.2 minutes on average; Diff = 33.4; SD = 12.1; 95% CI -40.4 to 26.4; P = 0.001). Eight patients preferred the crestal procedure and six had no preference. Crestal implants lost 0.99 mm (SD = 0.55) of peri-implant bone height versus 1.02 mm (SD = 0.57) for lateral ones, the difference being not statistically significant (0.03 mm; 95% CI of difference -0.52 to 0.59; P = 0.89) CONCLUSIONS. Both techniques produced successful outcomes, but the crestal technique required less surgical time and was preferred by patients.
