Conference Program:

Guided Bone Regeneration

For successful dental implant placement in a prosthetically ideal position, it is essential to have sufficient bone height and width at the recipient site to ensure both functional and aesthetic outcomes. When the available bone volume is insufficient for implant placement, various ridge augmentation techniques have been proposed.

Recent experimental and clinical studies have shown that guided bone regeneration (GBR) combined with dental implants can successfully regenerate bone around exposed implant threads. The final outcome of these procedures is influenced by biological, technical, and material-related factors.

This presentation will critically review the evidence from experimental and clinical studies on the GBR principle, both with and without the use of bone grafts under varying conditions. It will highlight critical surgical considerations and factors impacting healing outcomes, relating these to practical clinical scenarios. Additionally, insights from current systematic reviews will also be discussed.
