Maxillary Sinus Lifting Procedures Using Xenogeneic Cortico-Cancellous Graft Material With Simultaneous Implant Placement: A 1- To 3-Year Follow-Up

Abstract

Abstract:Aim: The aim of this study was to evaluate retrospectively the clinical outcomes of laterally approached sinus floor lifting with xenografts and simultaneously dental implant placement procedures. Material and methods:All patients treated with sinus lifting and simultaneous implant placement procedure and were followed for at least 1 year were retrospectively selected for this study. The lateral window technique was performed using a xenogeneic corticocancellous grafting material and submerged implants were placed immediately. Survival rates of implants and clinical features of patients and implants were evaluated.Results : A sample of 30 patients, 42 implants were placed according to the one-stage approach. Residual preoperatively alveolar ridge height varied between 3 and 6 mm with a mean of 4.58 mm and the bone gain at 1-year follow-up varied between 6 mm and 10 mm with a mean of 8.6 mm. Only two implants were lost before loading and overall survival rate was 96% for the implant-based analysis. Conclusions:Maxillary sinus lifting procedure with xenogeneic cortico-cancellous graft material and simultaneously implant placement was showed as a predictable and successful treatment modality.
