Vertical bone augmentation

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.

 

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.

 

Advantages of Yxoss CBR® compared to conventional titanium mesh or titanium-reinforced membranes:

  • Customizing can lead to a shortened operation time and fewer complications, as there are no sharp edges or restoring forces.
  • Easier fixation - with one or two screws as needed - which is also possible in the coronal area.
  • Incorporating a pre-determined break point also makes removal of the titanium mesh easier.
  • The augmentation material can be determined individually in relation to autogenous bone and bone replacement.
