Summary
Indirect sinus lifts using osteotomes without bone graft material effectively increase residual crestal bone height. This technique is valid for placing implants in atrophic posterior maxillas.
Area of Science:
- Dental implantology
- Oral surgery
Background:
- Atrophic posterior maxilla poses challenges for dental implant placement.
- Maxillary sinus elevation is a common procedure to augment bone height.
Purpose of the Study:
- To systematically review and meta-analyze the efficacy of indirect sinus lifts without bone graft material.
- To evaluate bone gain and implant survival rates associated with this technique.
Main Methods:
- Systematic literature review and meta-analysis of studies published between January 2005 and January 2012.
- Included studies focused on osteotome-based indirect sinus lifts without bone graft material and a minimum 5-month follow-up.
Main Results:
- Eleven articles were included in the analysis.
- The mean gain in residual crestal bone height was 3.43 mm ± 0.09 mm (range: 2.5-4.4 mm).
- Implant survival rates ranged from 94% to 100%.
Conclusions:
- Indirect sinus lift using osteotomes without bone graft material is a valid technique for increasing crestal bone height.
- This method enables successful dental implant placement in posterior maxillary atrophy with initial crestal heights of 5-9 mm.
