Summary
Endoscope-guided sinus elevation provides adequate bone for dental implants. This minimally invasive technique offers high implant success rates and reduces complications.
Area of Science:
- Oral Surgery
- Implant Dentistry
- Maxillofacial Reconstruction
Background:
- Sinus floor elevation augments the atrophic maxillary posterior region for dental implants.
- Minimally invasive techniques are sought to improve outcomes and reduce complications.
Purpose of the Study:
- To assess the efficacy of endoscope-guided internal sinus elevation for bone augmentation.
- To determine if this procedure yields sufficient bone support for stable implant placement and long-term success.
Main Methods:
- Sixty-two implants were placed in 30 patients following endoscope-guided internal sinus elevation without grafting material.
- Radiographs and Resonance Frequency Analysis (RFA) evaluated bone levels and implant stability.
Main Results:
- Significant bone gain was achieved in premolar and molar sites.
- Implants demonstrated sufficient stability (ISQ=60) with a 94% success rate during healing.
- A 100% success rate was observed after loading, with no further failures.
Conclusions:
- Endoscope-controlled internal sinus floor elevation is a reliable technique for maxillary augmentation.
- The procedure results in minimal trauma, good initial stability, and high long-term implant success rates.
- Visual guidance by endoscope aids in complication management, such as sinus membrane perforation.
