Guided bone regeneration (GBR) is one of the most utilized techniques to regenerate bone volume for future implant placement. GBR is defined as: “A surgical procedure with the goal of augmenting bone volume in edentulous or peri-implant areas using a barrier membrane, often in conjunction with bone grafting materials and/or biologics ...

2020年10月10日 · Within their limits, the present results have shown that staged and simultaneous vertical reconstruction of deficient alveolar ridges by means of GBR with titanium-reinforced d-PTFE membranes combined with a bilaminar split-thickness flap design delivered predictable hard tissue formation as determined clinically and radiographically.

2019年8月1日 · The staged GBR approach has clear advantages when bone width or height is inadequate for the primary placement of dental implants or in order to achieve the best prosthetically guided position(s).

In the anterior maxilla, staged GBR procedures are conducted not only to provide adequate bone volume for implant placement but also to restore a proper and stable contour of the orofacial ridge for improved long-term esthetics.

For smaller bone defects a simultaneous GBR approach delivers the same results as a staged GBR approach. With large hor-izontal ridge atrophy and vertical defects, a staged protocol seems to be more predict-able and produce better results.4.

To determine whether vertical ridge augmentation (VRA) can be obtained through guided bone regeneration (GBR) using exclusively resorbable collagen membranes and particulate bone substitutes without additional stabilization. This study retrospectively examined 22 participants who underwent VRA with staged or simultaneous implant placement.

2024年3月27日 · One stage GBR involves simultaneous implant placement and ridge augmentation, minimizing the number of surgical interventions and overall treatment time. This technique offers convenience for both patients and clinicians, resulting in reduced chairside time and potential cost savings.

2018年6月1日 · The main outcome measure was survival rate of dental implants placed in the ridge augmented by the GBR procedure (simultaneously or staged) performed using resorbable collagen membranes and particulate bone grafts.

Staged GBR for horizontal augmentation in preparation for implant placement when residual crest is 2.9 mm or wider. Block bone grafts as a two-stage approach when the initial width of the ridge is at least 3.2 mm.

Numerous options have been suggested for staged ridge augmentation such as onlay block grafts, interpositional block grafts, guided bone regeneration (GBR), ridge splitting and distraction osteogenesis. 4 In addition, various bone grafting materials have been described in the literature, including autogenous, allograft, xenograft and synthetic ...
