Maxillary Sinus Floor Augmentation With Autogenous Bone Graft From the Ascending Mandibular Ramus

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Regenerative Dentistry

Background:

• Maxillary sinus floor augmentation is crucial for dental implant placement in atrophic maxillae.
• Autogenous bone grafts from the mandibular ramus are a common source for this procedure.
• Long-term outcomes regarding patient satisfaction and esthetics are important for evaluating this treatment.

Purpose of the Study:

• To evaluate patient satisfaction and esthetic outcomes 10 years after maxillary sinus floor augmentation.
• To assess the long-term success of dental implants placed in augmented maxillary sinuses using autogenous bone grafts.

Main Methods:

• Retrospective analysis of 48 patients undergoing maxillary sinus floor augmentation with mandibular ramus bone grafts (2002-2006).
• Evaluation of 34 sinus augmentation procedures and 37 implants in 24 patients after 10 years.
• Subjective patient and professional assessments of peri-implant soft tissue, implant crown, and overall treatment esthetics.

Main Results:

• 10-year survival rates for suprastructures and implants were 84% and 100%, respectively.
• Patients reported high satisfaction (>90 on visual analog scale) with esthetic and implant treatment outcomes.
• Mean pink esthetic score was 9 (max 14) and white esthetic score was 8 (max 10).

Conclusions:

• Maxillary sinus floor augmentation using autogenous bone grafts provides high long-term implant survival.
• This procedure leads to significant patient satisfaction and favorable esthetic results for dental implants.
