Small Bone Defects Augmentation

摘要

The aim of the study was to compare different techniques for small alveolar crest bone defect augmentation with implants adapted to these bone defects. Platform switching , machined collar and zirconia collar implants were placed in the upper and lower jaw in two patients. The bone was placed around the implant on the buccal side and stabilized with osteosynthesis screws. Zirconia collar implant is a very simple method to apply, which can be also useful in the esthetic zone for soft tissue support; its white colour also plays an important esthetic role.
