Introduction
Horizontal or vertical alveolar bone augmentation procedures usually cannot be avoided in edentulous regions. Many studies have shown that GBR is predictable treatment at infrabony defects. However, GBR on extrabony defects still shows a lack of predictability.
Purpose
This study aims to clinically and radiographically evaluate a bone gain on extrabony defects after GBR using Oss-builder with or without collagen membrane.
Materials & Methods
Surgical produce
Oss-builder was selectively applied to each region with extrabony defects. In horizontal bone augmentation cases, 1 Wall Oss-builders (buccal length 9mm, buccal width 10mm) were used. In vertical bone augmentation cases, 3 Wall Oss-builders (buccal length 9mm, buccal width 12mm)
Results
All implants were followed up at least 9 months after implant 1st surgery and the survival rate was 100%. At implant 2nd surgery, all of the implants’ ISQ was measured more than 60.

Conclusion
Although hard tissue gain between when membrane was used and not used didn’t show statistically significant difference, horizontal bone gain more than 2mm, which is important for the long-term prognosis of the implant, could be assured. This results suggested that GBR using Oss-builder can be considered as a valuable treatment option for GBR on extrabony defects.
