Hypothesis
The osseodensification technique used for transcrestal sinus floor elevation would result in a low membrane perforation rate.
Conclusion
The osseodensification technique resulted in a low membrane perforation rate, with certain risk factors identified.
Supporting Evidence
- The study included 621 patients across six centers.
- Sinus membrane perforation occurred in 49 cases, representing a 7.31% rate.
- RBH ≤3 mm was identified as a significant risk factor for perforation.
- Most sinus lifts were performed in the molar region and in healed bone sites.
Takeaway
This study looked at how often the sinus membrane gets damaged when using a special drilling technique for dental implants, and found it happens less often than with older methods.
Methodology
A multicenter cross-sectional study evaluating sinus membrane perforation rates during transcrestal sinus floor elevation using osseodensification burs.
Potential Biases
The study involved multiple centers, which may introduce variability in surgical techniques and patient populations.
Limitations
The study did not follow up on the long-term performance of the implants placed.
Participant Demographics
Patients over 18 years old, average age 57.9 years, missing maxillary posterior teeth.
Statistical Information
P-Value
p<0.001 for RBH <3 mm as a risk factor.
Statistical Significance
p<0.05
