PurposeThe aim of this prospective and preliminary study was to compare the clinical and radiographic outcomes of two types of rough surfaced implants after implant placement in the atrophic posterior maxilla with sinus membrane elevation without bone grafting using the crestal approach.Materials and MethodsAll clinical and radiographic records for 28 patients who received 40 implants were included in this study. The patients were recalled for radiographic and clinical examinations at 1, 3, and 6 months and every 6 months thereafter following implantation.CBCT images were taken to evaluate the amount of bone gain in the maxillary sinus. Standardized periapical digital radiographs were taken to evaluate changes in the crestal peri-implant bone level and peri-implant fixture radiolucency.ResultsThe Kaplan-Meier survival estimates demonstrated a 100% probability of survival to 24 months. There were no significant differences in cervical bone loss (CBL) and residual bone height (RBH) between the TS III CA group and the TS III SA group during the 2 years of follow up after implant placement. The CBL values according to gender, implant placement region, prosthesis type, and the time of implantation were not significantly different between the two groups.ConclusionThis preliminary study demonstrates that two types of rough surfaced implants placed in the atrophic posterior maxilla with sinus membrane elevation without a bone graft have good clinical and radiographic outcomes.
