Bone Grafting And Socket Preservation

Extraction Socket Preservation

Following tooth extraction, the alveolar ridge undergoes horizontal and vertical dimensional changes. It is common to see approximately 50% of the alveolar width and height resorbed within the first three months. This can lead to ridge deformation and other complications.

Problems associated with ridge resorption for crown and bridge restorations include:

* Gap between the pontic and the soft tissue of the ridge

* Impaired phonetics

* Impaired aesthetics

* Hygiene complications
 

Problems associated with ridge resorption for implant placement procedures include:

* Insufficient bone for implant placement

* Need for subsequent invasive Guided Bone Regeneration treatment
 

Ridge preservation with Geistlich biomaterials

The use of scientifically documented biomaterials such as Geistlich Bio-Oss Collagen® and Geistlich Bio-Gide® in ridge preservation procedures can provide new bone formation and restore the hard tissue.

Regenerative treatment also may result in:

* Reduced number of secondary augmentations at implant placement.

* Superior volume preservation under pontics.

A regenerative approach with Geistlich Bio-Oss Collagen® and Geistlich Bio-Gide® to prevent hard tissue loss following a tooth extraction.


Bone Graft/Augmentation

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

Autogenous bone and/or a biomaterial is placed into the bony defect to maintain space and stimulate formation of new bone. The filled defect is then covered with a barrier membrane to assist in wound-healing and prevent the ingrowth of soft tissue.

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

Why use a bone substitute instead of autogenous bone?

Autogenous bone is effective in stimulating new bone formation and is considered to be the preferred grafting material. The harvesting of patient bone can cause additional pain as well as prolong surgery and recovery time. In addition, autogenous bone is subject to a certain degree of resorption.

Biomaterials are a valuable alternative to autogenous bone and possess several advantages. Geistlich bone substitute materials eliminate both the harvesting of patient bone and the additional discomfort associated with a second surgical site.

In addition, they offer a stable scaffold for bone formation and help to attain longterm volume preservation due to their low resorption rate. For these reasons, Geistlich Bio-Oss® is the most frequently used bone substitute material in dental bone regeneration.


Why use a barrier membrane?

Use of a membrane ensures undisturbed bone regeneration in the protected area and strongly enhances bone regeneration.

More than 16 years of clinical experience have shown that a native collagen membrane, such as Geistlich Bio-Gide®, provides an ideal barrier to ensure optimal tissue integration and complication-free healing. Surgical removal is not necessary since the membrane is naturally resorbed by the body.
