Transcrestal Maxillary Sinus Membrane Elevation using Osseodensification Compared with Alveolar Ridge Augmentation...

Area of Science:

• Dentistry
• Oral Surgery
• Implantology

Background:

• Maxillary sinus floor elevation is crucial for dental implant placement in atrophic maxillae.
• Traditional methods include osteotome-mediated sinus floor elevation (OMSFE) and lateral window augmentation (MSFA).
• Osseodensification offers a novel approach to transcrestal sinus membrane elevation (TSMEOD).

Purpose of the Study:

• To compare implant outcomes between TSMEOD and conventional sinus lift techniques.
• To evaluate primary and secondary outcomes including implant survival, stability, and surgical parameters.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials (RCTs) published up to March 2025.
• Included RCTs had a minimum six-month follow-up period.
• Primary outcomes: implant and superstructure survival. Secondary outcomes: ISQ, bone gain, complications, surgery duration, and patient-reported outcomes.

Main Results:

• Six high-risk, low-GRADE RCTs were included.
• Comparable high implant survival rates were observed across all techniques.
• TSMEOD showed significantly higher implant stability quotient (ISQ) and reduced surgery duration, complications, and analgesic use compared to OMSFE and MSFA.

Conclusions:

• TSMEOD demonstrates comparable implant survival to OMSFE and MSFA in short-term studies.
• TSMEOD offers potential advantages in reduced surgical morbidity.
• Further long-term RCTs are necessary to establish superiority of TSMEOD.
