30 Years of GBR in Implant Dentistry: Development, progress and state-of-the-art

Description

This webinar lecture will present 30 years of development and progress with GBR in implant patients. The development started in the late 1980â??s. The first 10 years was a development phase, in which the basic principles of GBR procedures were developed and improved. After the millennium change, a phase of routine application started with fine-tuning efforts, to improve the outcomes and to make GBR more patient friendly by reducing the patientâ??s morbidity and reducing healing periods.  In esthetic implant sites, the technique is called Contour Augmentation, since the goal of bone augmentation is an over-contouring of the ridge to optimize the esthetic outcome. The technique is using a 2-layer Composite Graft with two synergistic bone fillers. As 1st bone filler, we use locally harvested autogenous bone chips to enhance new bone formation during the initial phase of bone healing. This osteogenic promotion is much better understood today, since the autograft chips quickly release growth factors into the surrounding blood clot as documented by numerous pre-clinical studies. This Bone Conditioned Medium (BCM) contributes to the initiation and progression of osteogenesis by exhibiting synergistic TGF-β1/BMP-2 activity. The 2nd bone filler is a low-substitution filler such as DBBM (deproteinized bovine bone mineral), which is superficially applied. It is used to optimize the augmentation volume and to improve the long-term stability of the augmented bone volume. The two synergistic fillers are covered by a resorbable collagen membrane. The membrane provides a temporary barrier function, and stabilizes the applied bone fillers. The surgery is completed with a tension-free, primary wound closure. The surgical procedure will be presented with different case reports, and documented by clinical and radiographic long-term studies using CBCT up to 10-years of follow-up.
