Guided bone augmentation
Techniques for bone augmentation
In many cases it is necessary to increase the volume of the alveolar ridge before placing dental implants. Tooth loss due to caries, periodontal disease, extensive infrabony cysts and trauma are the main causes of alveolar bone loss.
Augmentation of the alveolar ridge is achieved by the use of bone grafts and the concomitant placement of semi permeable membranes (absorbable or not). The alveolar ridge can be augmented mainly at width and less predictably at height.
Applying technique for guided bone regeneration to a defective ridge in a maxillary second premolar region. Allograft and absorbable collagen membrane were placed to address the deficit and increase the width of the crest.
Applying guided bone regeneration to a defective ridge in the region of a maxillary central incisor. Bone defect was reaching approximately up to the floor of the nose (radiographic data). Xenograft and an absorbable collagen membrane were placed.
