Guided bone regeneration

Posted on Jul 16, 2020

Why is guided bone regeneration technique so important and even irreplaceable in bone grafting and implantation? Membrane separates epithelium and other soft tissues from bone matrix, therefore, soft tissue does not interfere with new bone formation in the wound. The overgrowth of epithelium is extremely unwanted. Moreover, membrane works not just as a simple barrier, but it also actively changes and facilitates some molecular processes, which occur during new bone formation.

No matter which brand of titanium implants you use, there should be enough bone tissue for correct bio integration. In order to achieve this state, some techniques should be applied. Guided bone regeneration is performed by precise isolation of fast-growing epithelium cells from slowly dividing bone tissue. If there is no full isolation of one type of cells from another, cells with higher proliferating state, namely, epithelium, will overgrow bone progenitor cells and destruct forming bone structure. By performing this technique there is a higher chance that an implant will not be rejected.

There are plenty of types of isolating collagen membranes, but overall, membranes which do not resorb over time are considered to be obsolete.

So as was mentioned before, a bone for future implant placement should be prepared. The most dangerous condition, which can interfere with implantation is bone resorption. Unfortunately, the loss of bone tissue leads to several unpleasant conditions. Firstly, impaired bone structure is less functional than a healthy one. Secondly, it leads to teeth loss and, therefore, poor esthetic result.
