“Is the guided bone regeneration of the posterior mandible reliable and stable.” Review of the 2015 ADF Congress 17 December 2015

Implant treatment in the posterior mandible presents many difficulties. Its anatomical characteristics and its reduced vascularisation can lead to failure. Its centrifugal resorption can cause bone defects in both the horizontal and the vertical planes. Therefore, it is essential to know the physiology of the osseous tissue and the mucous membranes at the mandible, along with any anatomical obstacles prior to placing implants or starting a bone augmentation.

Comparable to guided tissue regeneration, the biological principle of guided bone regeneration is based on the selection principle and competing soft-tissue cells. Exclusion of epithelium and connective tissue while maintaining enough space for bone regeneration is primordial. The membranes provide this barrier thanks to biomaterials.

Two clinical principles must be maintained: primary stability and implant position in the buccal corridor.

The resorption type of the posterior mandible will determine whether the implant will be immediate or delayed from the bone augmentation.
