Summary
Osteotome-mediated transcrestal sinus floor elevation is a safe dental implant technique with a high survival rate. Patients found the procedure uncomfortable, requiring thorough preparation.
Area of Science:
- Dentistry
- Oral Surgery
- Implantology
Background:
- The osteotome-mediated transcrestal sinus floor elevation technique is a method for augmenting bone in the posterior maxilla.
- This technique is used to facilitate dental implant placement in partially and completely edentulous patients.
Observation:
- A series of 66 implants were placed in 55 patients over 6 years using this technique.
- Bio-Oss bone graft material was used in over 60% of cases to enhance stability.
- The surgical procedure was generally safe and well-tolerated by patients.
Findings:
- The implant survival rate was 98.5% during healing and 100% after loading.
- Patient-reported pain levels were similar between the osteotome technique group and a control group without the technique.
- However, patients undergoing the osteotome technique reported significantly higher levels of discomfort.
Implications:
- The osteotome-mediated transcrestal sinus floor elevation technique demonstrates high success rates for dental implants.
- Patient education and preparation are crucial due to the potential for procedural discomfort.
- This technique offers a viable option for prosthetic rehabilitation in atrophic posterior maxilla cases.
