Summary
Sinus lift surgery is successful even with thickened sinus membranes, showing a high dental implant success rate. Membrane thickness often decreases post-procedure, indicating it
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Dentistry
- Implantology
Background:
- Thickened sinus membranes can pose challenges for maxillary sinus augmentation.
- Assessing the impact of sinus lift on membrane thickness and implant success is crucial.
Purpose of the Study:
- To evaluate dental implant success rates.
- To assess changes in sinus membrane thickness after sinus lift in patients with pre-existing membrane thickening.
Main Methods:
- 16 patients with thickened sinus membranes (>2 mm) and adequate bone height underwent sinus lift and dental implant placement.
- Cone-beam CT (CBCT) evaluated sinus membrane thickness pre-surgery and 6 months post-surgery.
- Short-term dental implant success was monitored.
Main Results:
- 18 implants were placed in 16 patients.
- Sinus membrane thickness decreased in 14 cases and increased in 2 cases post-sinus lift.
- All dental implants achieved successful short-term outcomes.
Conclusions:
- Sinus augmentation is feasible in patients with thickened sinus membranes.
- Pre-existing sinus membrane thickening does not contraindicate sinus lift procedures.
