Summary
The Intralift® procedure effectively promotes new bone formation in the sinus using bovine grafting material, even with minimal existing bone. This allows for successful dental implant placement without autogenous bone.
Area of Science:
- Oral Surgery
- Periodontology
- Regenerative Medicine
Background:
- Sinus grafting is crucial for dental implant placement in atrophic maxillas.
- Transcrestal sinus elevation techniques aim to augment bone height.
- Limited bone height (<5mm) presents a challenge for conventional grafting.
Purpose of the Study:
- To assess the efficacy of the hydrodynamic ultrasonic Intralift® procedure.
- To evaluate a bovine bone substitute in sinus grafting without autogenous bone.
- To determine the suitability of this method for creating implant recipient sites.
Main Methods:
- A multicenter case study involving 12 patients (16 sinuses).
- Crestal approach utilizing ultrasonic tips for bone preparation.
- Schneiderian membrane elevation and introduction of bovine grafting material (Bego Oss).
- Histomorphometric analysis of biopsies after 6 months.
Main Results:
- Significant new vital bone formation (average 33.4%).
- Integration of bone substitute material (average 43.6%).
- Absence of abnormal inflammatory signs.
Conclusions:
- The Intralift® procedure facilitates new bone generation in the sinus.
- Bovine grafting material can be used successfully without autogenous bone.
- This technique enables subantral implant placement in deficient bone sites.
