Summary
Sinus floor elevation using autogenous bone grafts effectively increases bone height for dental implants in the posterior maxilla. This reliable pre-implant procedure allows for successful dental implant placement with a high success rate.
Area of Science:
- Oral and Maxillofacial Surgery
- Periodontology
- Dental Implantology
Background:
- Maxillary sinus expansion and alveolar bone resorption limit dental implant placement.
- Sinus floor elevation is a surgical solution to augment bone height.
- The Tatum 'top hinge door' method is a specific sinus grafting technique.
Purpose of the Study:
- To evaluate the efficacy of sinus floor elevation using cancellous iliac bone grafts.
- To assess the success rate of ITI screw type implants placed in augmented maxillary sinuses.
- To determine the reliability of this pre-implantological procedure.
Main Methods:
- Performed 62 sinus floor elevations using autogenous cancellous iliac bone grafts in 42 patients.
- Inserted 161 ITI screw type implants into the augmented alveolar process.
- Followed patients for 1-6 years post-implantation.
Main Results:
- No implants were lost during the follow-up period.
- Two cases of infection occurred, and one implant required extended integration time.
- ITI screw type implants demonstrated suitability for placement in grafted sinuses.
Conclusions:
- Sinus floor elevation with autogenous cancellous bone grafts is a valuable and reliable pre-implant procedure.
- Proper pre-operative assessment and careful surgical technique are crucial for success.
- This technique enables dental implant placement with a high success rate in cases of insufficient bone height.
