prospective study of bone augmentation with lateral sinus lift and osseointegration of dental implants

Conditions: Atrophic Maxilla; Partial Edentulism

Summary: by using a split-mouth model in the maxilla, lateral sinus lift procedures will be performed using xenograft on one side vs autologous bone augmentation and prf membranes on the other side. the purpose is to qualify and verify each step of this study to ensure the reliability and validity of the results.

title: "histomorphometric evaluation of bone augmentation using xenografts versus autologous bone grafts in dental implant patients: a comparative clinical study" objective: this study aims to compare and analyse the effectiveness of xenograft and autologous bone grafts in bone augmentation procedures for patients requiring dental implants in a clinical setting. by comparing the outcomes of bone augmentation using xenografts and autologous bone grafts, this study aims to develop treatment protocols prioritising reduced invasiveness and enhanced efficiency. understanding which grafting material yields better osseointegration can lead to more streamlined procedures, benefiting clinicians and patients. furthermore, we aim to assess their efficacy in achieving optimal outcomes in bone augmentation procedures by implants and biomaterials in the study. the unique aspect of this study is the use of a split-mouth model and advanced digital technologies for data collection and analysis, which can provide more accurate and comprehensive insights into the comparative effectiveness of xenografts and autologous bone grafts. methodology: utilizing a split-mouth model in the maxilla, external lateral sinus lift procedures will be performed using xenograft on one side and autologous bone augmentation and prf membranes on the other side of the patients. a total of 20 patients will be included, with 40 implants placed. as part of the study methodology, digital technologies will be utilised for data collection and analysis. this includes digital imaging techniques for pre-operative assessment and post-operative evaluation of bone augmentation outcomes. by leveraging digital technologies, we aim to enhance the accuracy and efficiency of data collection, enabling comprehensive analysis of the comparative effectiveness of xenografts and autologous bone grafts. rest assured, every step of this study has been meticulously planned and executed to ensure the reliability and validity of the results. rationale: the success of dental implants, particularly in cases of partial or total edentulism with jaw atrophy, hinges on achieving primary stability and osseointegration. bone augmentation using either xenograft or autologous bone has been commonly employed for such treatments. however, there is an urgent need for further clinical research to evaluate the osseointegration outcomes between xenografts and autologous bone in bone augmentation procedures. the comparative analysis of xenografts and autologous bone grafts will provide crucial insights into the prevention and management of complications such as infection, graft failure, and resorption associated with bone augmentation procedures. by identifying which grafting material leads to fewer biological and technical complications, clinicians can tailor treatment protocols to minimize adverse events and maximize patient safety. this aligns with straumann's commitment to continuously improving treatment protocols to ensure the long-term success of dental implants and restorative procedures. significance: with the ageing population and increasing prevalence of partial or total edentulism, the challenges associated with dental implants will continue to rise. bone augmentation using xenografts or autologous grafts can potentially enhance implant stability and success rates, improving patients' quality of life and mental well-being. this study aims to contribute valuable insights into treatment protocols that can positively impact patient outcomes.
