Augmentation with bone substitute material
Guided Bone Regeneration (GBR)
In the past, implants were only placed in the jawbone where there was adequate size and density, which limited the indications for their use.
We now plan to place implants where they are most desirable from a prosthetic point of view. This has been made possible, among other things, by bone reconstruction procedures.
At UNIDENT UNION® clinic, we use quality-confirmed, authorised Bio-Oss and Bio-Gide products. Statistically, 41% of implant insertion procedures require the additional contribution of guided bone regeneration (GBR).
The decision to extend the procedure sometimes has to be made by the doctor during the operation itself.This is because it is only during the procedure that it is possible to see the need for alveolar reconstruction or expansion in a specific area. Even a CT scan only shows an image of the transverse dimension of the bone. The generation of new tissue and the thickening of the bone layer is achieved by the GBR procedure. It is essential for the surgeon to prevent the movement of epithelial cells and cells arising from connective tissue towards the newly formed bone tissue. Physical barriers in the form of special membranes are used for this purpose.
The use of biomaterials - bone substitutes combined with a membrane - makes it possible to achieve complete regeneration of the damaged bone around the implant or to widen the missing own bone in the desired direction.
After a period of 6-9 months, the particles of the biomaterial used fuse with the bone and provide the basis for the body to create a new bone structure, and then gradually decompose. The membrane is absorbed by the body once it has fulfilled its role.
Once the process of guided tissue regeneration is complete, the bone is permanently altered and subsequent radiological images are often indistinguishable from your own bone!
HOW CAN THE BONE BE REBUILT?
Human bone tissue has the capacity to regenerate, in other words to rebuild missing bone. However, in most cases, the body needs help. The natural products Bio-Oss and Bio-Gide effectively support the body's own processes during bone reconstruction.
Newly formed bone needs a scaffold that behaves like a structural skeleton. The bone substitute material Bio-Oss, with its highly porous structure, meets this requirement perfectly. The Bio-Gide membrane is placed on the surface of the healing bone and serves as a protective barrier to prevent fast-growing soft tissue from growing into the space that should be occupied by slow-growing bone. In addition, Bio-Gide promotes proper wound healing.
WHAT ARE BIO-OSS AND BIO-GIDE?
Bio-Oss and Bio-Gide are natural products. Due to their high similarity to human tissue, they ideally stimulate the bone formation processes of tissue healing taking place in the human body. During the healing process, they integrate into the tissues and then gradually decompose during the metabolic processes in the human body. In the case of Bio-Oss, this process can take several years, while the Bio-Gide membrane is completely broken down within a few months.
Bio-Ossis a zoonotic product. During the production process, the organic elements are removed, so that only the hard part of the bone consisting of calcium compounds remains.
Bio-Gideis a membrane produced from animal collagen. In the human body, collagen protein is the main component of skin and connective tissue. The natural protein structure of Bio-Gide accelerates wound healing processes and, thanks to its specific action as a protective barrier, enables optimal bone regeneration.
HOW IS THE TREATMENT CARRIED OUT?
The bone reconstruction procedure takes place in one or two stages.
One-step- bone reconstruction and implant insertion take place at the same time
- dental implant - insufficient bone (both vertically and laterally)
- application of Bio-Oss - filling the bone defect with Bio-Oss to form new bone
- use of Bio-Gide - in order to protect the forming bone, the wound is covered with Bio-Gide membrane
Two-stage- insertion of the implant only takes place after completion of the bone reconstruction after approx. 6 months
- use of Bio-Oss - filling a bone defect with Bio-oss material to create new bone (e.g. Sinus Lift)
- use of Bio-Gide - in order to protect the forming bone, the wound is covered with Bio-Gide membrane
- dental implant - is inserted after the completion of the bone reconstruction, i.e. after approx. 5-6 months
