Minor bone augmentation

Guided bone regeneration (GBR) is a surgical procedure that uses grafting materials and barrier membranes to stimulate and direct the growth of new bone at defect sites.

Autologous bone, and/or a biomaterial, is placed into a bone deficient area, maintaining space and stimulating formation of new bone. Barrier membranes covering the filled defect prevent the ingrowth of soft tissue. 

GBR approaches are used, for example, to restore bone in case of fenestration or dehiscence defects around an implant, to compensate for major jawbone deficiencies or to avoid bone resorption after tooth extraction in deficient alveoli.

Why use a bone substitute instead of autologous bone?

Autologous bone best stimulates new bone formation and therefore seems to be the preferred grafting material. Harvesting patient bone, however, causes pain and prolongs surgery and recovery time. In addition, autogenous bone is subject to a certain degree of resorption1.
Biomaterials are a valuable alternative to autologous bone and show several advantages. Geistlich bone substitute materials spare the patient painful bone harvesting, offer a stable scaffold for bone formation and help to attain long-term volume stability due to their low resorption rate2. For these reasons, Geistlich Bio-Oss® is the most frequently used bone substitute material in dentistry3,4.

“GBR with Geistlich biomaterials is a successful therapy from an esthetic and functional point of view with a high degree of predictability and low risk of esthetic complications.”
Prof. D. Buser, Berne, Switzerland

 

Why use a barrier membrane?

Use of a membrane ensures undisturbed bone regeneration in the protected area and strongly enhances bone regeneration5,6.
More than 16 years of clinical experience have shown that a native collagen membrane such as Geistlich Bio-Gide® provides an ideal barrier, and ensures optimal tissue integration7,8 and complication-free healing9. Surgical removal is unnecessary as the membrane is resorbed by the body.

Geistlich Bio-Oss® and Geistlich Bio-Gide® are the most frequently used products in regenerative procedures such as minor bone augmentation3,4.

They ensure

  • Reliable bone formation10-15.
  • Excellent osseo-integration and long-term volume preservation12,16,17.
  • Long-term implant survival rate18.   
  • Complication-free healing9.
  • Excellent aesthetic outcome19.


Geistlich biomaterials are reliable and facilitate procedures even for less experienced surgeons.
