Sinus augmentation for dental implants: the use of autogenous bone

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Bone Grafting Techniques

Background:

• Autogenous bone has been the preferred graft material for sinus augmentation at our institution since 1983.
• Successful sinus grafting relies on achieving functional stability for dental implants.

Purpose of the Study:

• To evaluate the long-term success of autogenous bone grafts in the sinus for supporting posterior maxillary restorations.
• To assess implant survival rates in conjunction with sinus augmentation using autogenous bone.

Main Methods:

• A retrospective analysis of patients undergoing sinus grafting with autogenous bone.
• Evaluation of functional stability and implant survival over a 10-year follow-up period in selected cases.
• Analysis of implant loss in relation to autogenous bone grafted sinuses.

Main Results:

• The criteria for successful sinus grafts were met, demonstrating functional stability in patients with long-term follow-up.
• Out of 173 implants placed in autogenous bone grafted sinuses, 20 implants were lost in four patients.
• The overall success rate indicates a high degree of predictability for this technique.

Conclusions:

• Autogenous bone grafting is a reliable method for sinus augmentation, providing functional stability for dental implants.
• Long-term follow-up is essential for all graft materials used in sinus augmentation to ensure sustained success.
• While generally successful, careful patient selection and monitoring are recommended to minimize implant loss.
