Guided tissue reconstruction can be performed to restore the supporting structure of a previously lost tooth, which, in addition to maintaining beauty, preserves the function of the tooth in the patient. Finaliy, cases are presented to demonstrate details ct surgical principles and techniques. Currently available membrane systems face certain disadvantages such as difficult clinical handling, inconsistent degradation, undirected cell growth and a lack of stability that often complicate their application. Of the different techniques, the best documented and the most widely used method to augment bone in localized alveolar defects is guided bone regeneration. GUIDED BONE REGENERATION-INDICATIONS [hr] Before this type of surgery, we need a complex clinical exam, a panoramic x-ray, a 3D CT scan and a set of lab investigations. These range from advances in barrier membranes; to changes in the type, size, and preparation of bone and particulate; to . Horizontal bone augmentation by means of guided bone regeneration. Guided bone regeneration is carried out when the bone is lost due to periodontal disease in order to give sufficient bone mass for bridges or dental implants. Thus, cells originating from the intact periodontal ligament is given time and space to repopulate the root surface . The theory of GBR technology is to selectively prevent epithelial cells and connective tissue cells from bone defect area through barrier membrane based on different migration rate of various. Membrane materials possess a number of properties which are amenable to modification. in 1988, inspired by the findings of Murray et al. Thus, indications for GBR consequently include mild horizontal and mild vertical defects (less than 3 mm) and small dehiscence/fenestration defects, the latter of which achieve . Class II furcation defects. Guided bone regeneration (GBR) is a technique used to facilitate bone regeneration, which uses a biocompatible membrane acting as a physical barrier to prevent the adjacent connective tissue from invading the bone defect. the concept of guided bone regeneration (gbr) was introduced to the profession over 30 years ago and entails using a barrier membrane during the healing process to exclude certain nonideal cell types, thereby allowing the growth of slower-growing bone cells. Prof Daniel Buser has assembled a team of the top names in implant surgery to put together a comprehensive guide on the materials, indications, techniques, timing, and results of GBR. Guided bone regeneration emerged from periodontology and the Guided Tissue Regeneration (GTR) technique. Its main indications are for three dimensional bone reconstruction. This resorption results in a reduction in alveolar bone volume, as shown in this clinical example of a missing upper right central incisor. polylactide or glycolide) or natural (e.g. Some scholars argue that GBR should be strictly defined as those cases using a barrier membrane. How to properly time and stage grafting, implant, and prosthetic therapy is a major focus. Avoid compressing the particles excessively during application; less packed particles leave space for blood vessel ingrowth and formation of new bone matrix. It is often necessary to augment the alveolar bone to ensure that implants can be placed correctly in the prosthodontically determined position and also be completely embedded in bone. In addition, these types of membranes show a high incidence of flap sloughing and membrane exposure that often lead to infection and unfavorable results. 3. Recently, GBR membrane . 3. A Guided bone regeneration membrane (GBR ) eg BioGuide, Tutoplast etc is placed over the defects to keep out non bone cells from surrounding soft tissues from invading and populating the bone defects.
