Summary
A palatal approach for maxillary sinus elevation with simultaneous implant placement is effective in select cases with thick buccal bone. This technique offers a viable alternative to traditional lateral window osteotomy for achieving successful implant restoration.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Regenerative Medicine
Background:
- Traditional maxillary sinus lift elevation with simultaneous implant placement often uses lateral window osteotomy.
- Anatomical variations, like thick buccal bone, may necessitate alternative approaches.
Purpose of the Study:
- To evaluate the feasibility of a palatal approach for maxillary sinus floor elevation with simultaneous implant placement in a patient with specific anatomical conditions.
Main Methods:
- A 48-year-old male with 2-3 mm residual bone height underwent a palatal approach sinus lift using the DASK kit.
- Simultaneous implant placement was performed, with bone graft material surrounding the implants.
Main Results:
- Postoperative CBCT showed a sinus graft height of 10 mm.
- At 7 months, CBCT confirmed bone-to-implant integration, mature osteogenesis, and no peri-implant radiolucency.
Conclusions:
- The palatal approach is a technically feasible treatment for maxillary sinus floor elevation and simultaneous implant placement.
- This technique is a preferable alternative in selected cases with specific anatomical variations, such as thick buccal bone walls.
