Objective
The purpose of this article is to describe a technique with a mini bone scraper for lateral bone window approach and simultaneous bone harvesting during sinus floor elevation.
Methods
This study included five consecutive patients with the atrophic posterior maxilla. After elevation of mucoperiosteal flap, a bone window was then opened safely using a Micross Mini Bone Scraper® with small shape and easy handling. Data were recorded on the residual alveolar bone height, number of implants, site of implant placement, collected particulate bone volume, and bone harvesting time.
Results
There was no injury of the Schneiderian membrane, and one to two implants of 11.5 mm length were placed simultaneously after sinus floor elevation in all cases. Mean residual bone height was 4.6 mm. The mean volume of particulate bone collected from the anterior wall of the maxilla using this technique was 0.74 cm3. Supplementary allogeneic materials were not required in all cases. Mean bone harvesting time was 4.6 min.
Conclusions
Our technique with Micross Mini Bone Scraper® is a simple and safe procedure in lateral bone window approach and simultaneous bone harvesting during sinus floor elevation, because it is performed under better visualization of the membrane without irrigation.
