Successful placement of implants requires sufficient alveolar ridge height. Conventional approaches to increase the ridge height include autogenous bone block grafting, interpositional bone grafting, and form-stable membranes.
Augmentation with bone blocks
Autogenous bone blocks are the material of choice to compensate insufficient bone height. Resorption, however, can result in functional and aesthetic complications.
Contouring the bone block with slow resorbing Geistlich Bio-Oss® bone substitute and covering the augmented area with a Geistlich Bio-Gide® collagen barrier reduces graft shrinkage. The volume of the augmented ridge remains stable1.
A mixture of autogenous particulated bone and Geistlich Bio-Oss® is used to cover the bone blocks and to cover steps between the margins of the grafts and the recipient bed. This procedure will simplify the contouring of the graft.
The grafts (blocks and particulated bone + Geistlich Bio-Oss®) are covered with a resorbable collagen membrane (Geistlich Bio-Gide®) in order to stabilise the particulated graft and to reduce the risk of bone resorption.
The final prosthetic result showing optimal reconstruction of the ridge with an aesthetic outcome.
Yxoss CBR® - Individually made 3D Titanium Mesh
Larger and complex augmentations, especially with a combined horizontal-vertical defect morphology, still present a major surgical challenge. In these cases, the augmentation material requires a high level of regenerative ability, which can be achieved by mixing Geistlich Bio-Oss® and autologous bone. In addition, long-term stabilization of the augmentation material is necessary, which the ReOss® Customized Bone Regeneration (Yxoss CBR®) mesh structure can provide. The aim of this technique is to use the tried and tested material titanium in combination with modern CAD/CAM technology to achieve defect-specific, customized bone regeneration.
