Horizontal Bone Augmentation
Successful placement of implants in complete or partly edentulous patients requires sufficient alveolar ridge width. Horizontal bone augmentation procedures increase the width of the ridge.
Conventional approaches include fixing an autogenous bone block graft into remaining lingual/palatal walls or stimulating new bone formation under titanium-reinforced membranes.
Autogenous bone block grafts
Autogenous bone block grafts are the material of choice to compensate for insufficient bone width. However, extensive resorption of the autogenous block graft can result in functional and esthetic failures.1 Contouring the autogenous bone block graft with Geistlich Bio-Oss® and covering the grafted area with Geistlich Bio-Gide® considerably reduces graft shrinkage.2
Case by Prof. Carlo Maiorana & Dr. Mario Beretta, Milan, Italy
An alternative GBR approach to obtaining additional bone width utilizes titanium-reinforced membranes which create space for bone formation.3 However, due to their material properties, they are associated with impaired healing of the overlaying soft tissue and are non-resorbable, requiring a second surgical procedure for membrane removal.4 In order to overcome this complication, Geistlich Bio-Gide® can be used to completely immobilize and protect a particulate bone graft that results in horizontal bone augmentation.5
- Geistlich Bio-Gide® is fixed securely with pins on the lingual/palatal and buccal aspects.
- The area is packed compactly with autogenous bone chips and Geistlich Bio-Oss® granules, creating a sausage skin effect.
- Graft material is completely immobilized and remains stable.
Geistlich Bio-Gide® collagen membrane provides a viable replacement for non-resorbable barrier membranes and does not require a second surgical procedure.
