Long-Term Clinical Outcomes of Transalveolar Maxillary Sinus Floor Elevation with Rotatory Instruments: An 8-Year...

Area of Science:

• Dental Implantology
• Oral Surgery
• Periodontology

Background:

• Transalveolar sinus floor elevation (TSFE) addresses reduced maxillary posterior alveolar bone height for dental implant placement.
• The minimal invasive sinus elevation (MISE) technique offers a less invasive approach to TSFE.

Purpose of the Study:

• To evaluate the clinical outcomes of TSFE using the MISE technique.
• To assess implant survival and complication rates in partially and totally edentulous maxillary patients.

Main Methods:

• Prospective clinical study adhering to STROBE guidelines.
• TSFE performed with MISE technique and simultaneous implant placement, with loading at 6 months.
• Bone height measured by CBCT; marginal bone loss assessed by periapical radiographs.

Main Results:

• Ninety-one patients received 107 implants with a mean 96.2-month follow-up.
• Achieved mean bone height increase of 4.3 mm with a 97.2% cumulative implant survival rate.
• Reported peri-implantitis (9.3%), membrane perforation (7.7%), and technical complications (5.5%).

Conclusions:

• The MISE technique is a successful protocol for posterior maxilla implants with reduced alveolar ridge height.
• Biological and prosthetic complication rates were below 10% over an average 8-year follow-up.
• This technique provides a viable solution for complex implant cases.
