Introduction: Fibrous dysplasia (FD) is a rare but important benign lesion affecting the maxillofacial region, which presents bone pain, deformities and fracture. Although FD presents radiographic patterns, it has to be analyzed histologically for the final diagnosis. Currently, there is no guide for FD treatment universally accepted. We report a success case of excision of the entire lesion in...
BACKGROUND Collagen membranes for guided bone regeneration (GBR) and guided tissue regeneration (GTR) are used extensively as bioabsorbable barriers. Cross-linking of collagen increases its biodurability and enables the control of its degradation kinetics and barrier function. A novel cross-linking technology was used to produce a porcine type I collagen membrane (GLYM). The purpose of this stu...
Alveolar ridge resorption has long been considered an unavoidable consequence of tooth extraction. While the extent and pattern of resorption is variable among individuals, there is a progressive loss of ridge contour as a result of physiologic bone remodeling. Over the long term, prosthodontic complications, loss of function, and inadequate bone for the placement of dental implants may result....
The world of dentistry knows the benefits and results guided bone regeneration. One most successful techniques introduced a decade ago utilizes, as barrier membrane, sheet made collagenated xenograft called lamina. Indications applications with different surgical have been well described by several authors. This technique not only presents very low degree complications, but also has some added ...
BACKGROUND/AIM A novel nanofibrous membrane of a degradable biopolymer poly (lactide-co-ε-caprolactone) (PLCL) for guided bone regeneration (GBR) was designed and its tissue compatibility and ability to promote the regeneration of new bone were investigated in a rat mandibular defect model. MATERIALS AND METHODS The nanofibrous structuring of the PLCL polymer was facilitated by a solvent-indu...
Polymer membranes have been widely used in guided tissue regeneration (GTR) and guided bone regeneration (GBR). In this review, various commercially available membranes are described. Much attention is paid to the recent development of biodegradable polymers applied in GTR and GBR, and the important issues of biodegradable polymeric membranes, including their classification, latest experimental...
Now a days most commonly used material to treat the defects in bone after trauma or any pathology are grafts. Bone grafting is procedure which performed surgically join defect surrounding for union of bone. It was found that graft allogenic nature as well other bioactive synthetic substitutes shows good integration with remaining To increase chances acceptance these materials and others additio...
Membranes for guided bone regeneration (GBR) were prepared from the synthetic biodegradable polymer poly-D,L-lactic/glycolic acid (PLGA). This GBR membrane has a bi-layered structure with a dense film to prevent gingival fibroblast ingrowth and ensure mechanical function, and a micro-fibrous layer to support colonization by osteogenic cells and promote bone regeneration. Hydrolysis and biodegra...
Osseous defects of the jaws following trauma, cysts, infection or congenital deformity may show poor osteogenesis and the affected area may never be completely filled with bone. It is widely accepted in guided tissue regeneration that physically halting soft connective tissue proliferation into bone allows bone regeneration. This concept is called the "osteopromotion principle." The purpose of ...
Guided bone regeneration (GBR) evolved from the concept of guided tissue regeneration (GTR) and has been used for reconstructing sites with bone deficiencies associated with dental implants. For GBR, the use of absorbable collagen membranes has been increasing, but, at present, scientific information on the use of collagen membranes for GBR is limited. This study was aimed to clinically and his...
