Vertical bone augmentation

Successful placement of implants requires sufficient alveolar ridge height. Conventional approaches to increase the ridge height include autogenous bone block grafts, inter-positional bone grafts, and titanium-reinforced membranes.  

Augmentation with autogenous bone block grafts

Autogenous bone block grafts are the material of choice to compensate for insufficient bone height. Resorption however, can result in functional and esthetic complications. Contouring the autogenous bone block graft with slow resorbing Geistlich Bio-Oss® bone substitute particles and covering the augmented area with a Geistlich Bio-Gide® collagen barrier reduces graft shrinkage. The use of these biomaterials provides long-term volume preservation of the augmented ridge1.


Augmentation with titanium-reinforced membranes

Currently, a titanium-reinforced membrane is required for large vertical ridge augmentation when an autogenous bone block graft is not utilized. Although these membranes are often used in these procedures, there is a risk of premature exposure and bacterial infection2,3. The use of Geistlich Bio-Gide® favors soft tissue healing and minimizes wound dehiscences4. A mixture of autogenous bone chips and Geistlich Bio-Oss® granules can be placed underneath the titanium-reinforced membrane. This facilitates both optimal bone formation which is induced by the autogenous bone chips, and volume preservation through the slow resorption rate of the Geistlich Bio-Oss®5 granules.
