TLDR
The resorbable membrane, Bio-Gide, in combination with a bone graft, can be a useful alternative to the well-established expanded polytetrafluoroethylene membranes.Abstract:
The purpose of this clinical investigation was to compare the new resorbable collagen membrane, Bio-Gide, to the conventional expanded polytetrafluoroethylene material (Gore-Tex) for guided bone regeneration in situations involving exposed implant surfaces. Over a 2-year period, 25 split-mouth patients were treated randomly: one defect site was treated with Bio-Gide and the other defect site with Gore-Tex; all 84 defects were filled with Bio-Oss and covered with the respective membrane. The defect types, their dimensions, and their morphology were measured in detail initially and at re-entry to allow for calculation of the exposed implant surface. Changes in defect surface for both types of membranes were statistically significant (P .94) could be detected between the two membranes. The mean average percentage of bone fill was 92% for Bio-Gide and 78% for Gore-Tex sites. In the latter group, 44% wound dehiscences and/or premature membrane removal occurred. The resorbable membrane, Bio-Gide, in combination with a bone graft, can be a useful alternative to the well-established expanded polytetrafluoroethylene membranes.read more

Which hard tissue augmentation techniques are the most successful in furnishing bony support for implant placement
Tara Aghaloo,Peter K. Moy +1 more
TL;DR: The maxillary sinus augmentation procedure has been well documented, and the long-term clinical success/survival (> 5 years) of implants placed, regardless of graft material(s) used, compares favorably to implants placed conventionally, with no grafting procedure.

Bone augmentation techniques.
TL;DR: The techniques for reconstruction of bony defects that are reviewed in this paper include the use of particulate bone grafts and bone graft substitutes, barrier membranes for guided bone regeneration, autogenous and allogenic block grafts, and the application of distraction osteogenesis.

Immediate or early placement of implants following tooth extraction: review of biologic basis, clinical procedures, and outcomes.
TL;DR: Immediate and delayed immediate implants appear to be predictable treatment modalities, with survival rates comparable to implants in healed ridges, and clinical outcomes of immediate and delayed implants were comparable to those of implants placed in healed alveolar ridges.

Bone augmentation procedures in localized defects in the alveolar ridge: clinical results with different bone grafts and bone-substitute materials.
TL;DR: There is a high level of evidence to support that survival rates of implants placed in augmented bone are comparable to rates of Implants placed in pristine bone.

Collagen Membranes: A Review
TL;DR: The use of grafting material in combination with collagen membranes seems to improve clinical outcomes for furcation, but not intrabony, defects when compared to the use of membranes alone, and the properties that make collagen membranes attractive for use in regenerative therapy will be addressed.
