PMID: 11958398 Purpose: Currently, a number of bioresorbable and biodegradable membranes used for guided bone regeneration lead to incomplete tissue regeneration. Poor mechanical properties, short degradation time, and the lack of integrated biologic components result in the inability to create and maintain an appropriate environment and to actively support tissue remodeling. In the present study, the osteogenic potential of human calvarial periosteal cells in combination with ultrathin polycaprolactone (pc2) membranes of a slow biodegradation rate was investigated. Materials and Methods: In vitro and in vivo analyses of the tissue-engineered constructs were conducted using imaging techniques, immunohistochemistry, and histology. Two types of membranes were investigated. Group 1 consisted of a plain membrane, and in group 2 membranes were treated with sodium hydroxide. Results: In vitro results showed that osteoblast-like cells attached and proliferated on the membranes with the formation of ...

Edentulism refers to a state of full or partial lack of teeth. This situation may interfere with essential functions such as mastication, speech and even appearance.. Dental implants inserted to the mandible or maxilla is a common treatment modality aiming to restore edentulus alveolar ridges by providing support and anchorage for removable or fixed dental prosthesis.There are cases which in addition to a lack of teeth suffer from lack of sufficient bone tissue volume to support the dental implant.A situation like this may originate from a variety of reasons such as residual bone atrophy, prior alveolar bone destruction due to periodontal disease and even a traumatic tooth extraction. In such cases, a routine alveolar bone augmentation is done to enable a dental implant installation at this site.Guided bone regeneration (GBR) is a widely used technique used to augment edentulus bone ridges. It relies on an inert membrane covering a bone substitute placed over the bony site requiring ...

Guided bone regeneration (GBR) is a reconstructive procedure of alveolar ridge using membranes. This procedure is indicated when there is no sufficient bone for implantation, or in the case of optimal implant installation for esthetic or functional needs. GBR can be performed before implant placement, when there is not enough bone for initial stability of implants and less predictable outcomes (staged approach), or performed simultaneously with implantation (combined approach). GBR techniques have been used for vertical and horizontal ridge augmentations with acceptable results. This literature review discusses the background, principles of GBR, the materials used in GBR (types of membranes and bone grafts), success criteria and long term results of GBR.

Guided Bone Regeneration, aka Bone Grafting, is a procedure that stimulates the formation of new bone in your jaw where bone is deficient or lacking.

AlloDerm GBR by BioHorizons is used as an effective barrier membrane in oral reconstruction and can be remodeled into the patients own tissue.

Records of 14 patients (7 male, 7 female) with a mean (SD) age of 36.78 (13.9) years who were treated for soft tissue recessions around implant-supported restorations in the maxillary central or lateral incisor location were analysed. Implant diameters ranged from 3.3-4.7 mm. All patients had bone loss confined to the labial surface of the implant. A solvent-dehydrated particulate mineralized allograft (Puros Cancellous Bone Allograft, Zimmer Biomet Dental, Palm Beach Gardens, FL) and a resorbable membrane (CopiOs Pericardium, Zimmer Biomet Dental) were used in a GBR surgical procedure in combination with a roughened titanium tenting screw placed 3-4 mm below the implant platform to restore unesthetic defects in the anterior maxilla..

It is becoming rare today to come across simple cases in Periodontics; our specialty has come to face complex cases where hard and soft tissue deficiencies are quite common. These suggested protocols and schematic approaches were developed to help the surgical practitioner visualize and divide the problem into a predictable step-by-step workflow. The utilization of 3-D printed CBCT studies of the treatment planned surgical sites was shown to be integral in patient care and clinical outcomes. Every step is dictated by biology; all incision designs, flap management techniques, and biomaterials used have been selected to maximize the blood supply in the area and minimize trauma to the vascular network that nourishes our surgical site. ...

Das Ziel dieser Arbeit war die Etablierung eines neuen Kombinationsmodels. Das verwendete Rattenmodel sah eine, sowohl schnitt- als auch aspirationsinduzierte, Form der Rückenmarksläsion mit nachfolgender Läsionsüberbrückung mittels eines Leitkanals vor. Die Leitschiene besteht aus einem neuartigen, biodegradierbaren Material und ist mit einer Mischung aus Matrigel® und Schwannzellen gefüllt. Die in der Leitschiene vorhandenen Microporen dienen sowohl zur Orientierung der regenerierenden Axone als auch zur Sicherung der Zellernährung, und hemmen zusätzlich die Migration unerwünschter Zellen aus der Umgebung in den Leitkanal. Die im Leitkanal implantierten Schwannzellen können ebenfalls als Leitstrukturen dienen. Sie orientieren sich in Längsrichtung und bilden Büngnersche Bänder. Zusätzlich sezernieren sie kontinuierlich neurotrophe Faktoren, die das Faserwachstum stimulieren. Die in unserem Labor verwendete Behandlung zur Hemmung der Narbenbildung wurde an beide Läsionsgrenzen ...

Objectives: Guided bone regeneration (GBR) is a commonly utilized surgical technique in the craniofacial region. The transcriptional mechanisms associated with this type of bone regeneration are not well understood. The aim of this study was to characterize the transcriptome associated with GBR of a critical-size calvarial defect in the rat. Material and methods: Critical-size calvarial defects were created in six Wistar strain rats and treated according to the principles of GBR. The tissue filling the regenerating defect was harvested at 7 and 14 days. Total RNA was extracted and microarray analysis was carried out to identify the differences in the transcriptome between days 7 and 14. Results: Gene ontology (GO) analysis of the genes up-regulated at day 7 showed that immature wound healing-related mechanisms, such as protein metabolism and cell proliferation, were upregulated at this time point. Furthermore, the immuno-inflammatory process was also up-regulated at the earlier time point. In ...

AU - Wendelschafer-Crabb, Gwen. AU - Kennedy, William R.. AU - Tranquillo, Robert T.. PY - 1999/1/1. Y1 - 1999/1/1. N2 - Bioresorbable collagen nerve guides filled with either magnetically aligned type I collagen gel or control collagen gel were implanted into 4- or 6-mm surgical gaps created in the sciatic nerve of mice and explanted 30 and 60 days postoperation (dpo) for histological and immunohistochemical evaluation. The hypothesis was that contact guidance of regenerating axons and/or invading nonneuronal cells to the longitudinally aligned collagen fibrils would improve nerve regeneration. The criterion for regeneration was observation of regenerating myelinated fibers distal to the nerve guide. Consistent with previous studies showing poor regeneration in 6-mm gaps at 60 dpo with entubulation repair, only ...

DOI: 10.11607/prd.1175 This report describes a novel bone reconstructive technique based on guided bone regeneration for extensive three-dimensional hard tissue augmentation. This two-stage technique utilizes bioresorbable osteosynthesis plates, pins, and collagen membranes that form a physical barrier resembling a fence, which contains the bone graft biomaterials composed of a combination of deproteinized bovine bone matrix and autologous bone grafted from intraoral sites. This technique can result in significant bone regeneration with minimal patient discomfort. Four case reports are presented. Histologic analysis of specimens shows the presence of mature bone. This procedure yields favorable results for bone formation, implant placement, and patient satisfaction. (Int J Periodontics Restorative Dent 2013;33:129 136. doi: 10.11607/prd.1175 ...

Periodontal or gum disease causes bone loss around teeth, which can increase the chances for tooth loss. The gums are attached to the underlying bone supporting the teeth. When gum disease is present, this supporting tissue and bone are destroyed and pockets in between the teeth and gums develop. Eventually, if too much bone is lost as a result of gum disease, the tooth will likely need to be extracted. Once a tooth has been lost, the supporting jaw bone has a tendency to disappear over time affecting the contour of the face. Loss of facial contour may make wearing dentures uncomfortable, and insufficient bone can render placing dental implants impossible. However, a doctor can provide simple techniques that are now available to regrow lost bone, provide support for dental implants, or to improve the aesthetics beneath a fixed bridge. Guided tissue bone regeneration does not always require the removal of bone from any other part of the body. Instead, doctors offer many options that use membrane ...

GBR Membranes and the Barrier Effect. Melcher, in 1976, described the theoretical principles of GTR (guided tissue regeneration around teeth) and these were later applied to GBR (guided bone regeneration for placement of dental implants). These principles are based on placing a physical barrier that prevents unwanted tissues invasion, allowing selective cell population of the wound site.

The most recent development in periodontal regeneration is the use of proteins to induce the formation of tooth supporting structures lost to periodontal disease. Available since 1999, the procedure calls for placing embryonic cells into the defect, which in turn stimulate production of new bone and tissue cells which reform the normal periodontal complex. These cells are porcine (pig), and carry no risk of disease transmission. While long-term studies are not yet available, the research to date warrants use of this approach under certain circumstances. (See Emdogain) The periodontist must decide in each case whether the chances of improvement warrant the added expense of bone regeneration. However, restoring bone and the periodontal complex is the gold standard, and periodontal regeneration is being used more and more ...

The purpose of this study is to compare a new biomaterial with an already existing treatment principle (Bio-Oss/Bio-Gide) with regard to their ability to preserve the dimensions of the alveolar ridge and to promote bone regeneration and to evaluate the early survival rate of dental implants placed in the augmented socket area and to assess radiographically and clinically changes of peri-implant soft and hard tissues ...

BEGO Implant Systems GmbH & Co. KG, Bremen, Germany. The loss of volume of the alveolar ridge that regularly occurs after tooth extractions can compromise the hard and soft tissue situation for implants and thus the aesthetic outcome. The principle of membranesupported guided bone regeneration (GBR) is currently the most commonly used technique for bone regeneration in the dental practice. The separation of the rapidly proliferating soft tissue from the more slowly regenerating hard tissue creates a protected compartment in which damaged or lost bone tissue can be regenerated. Commercially available barrier membranes can be clearly differentiated from one another on the basis of several properties. Factors such as source tissue and preparation process have been just as exhaustively studied as the effect of the species from which the collagen was harvested or the networking properties. To what extent these factors are essential for the biodegradation time of a barrier membrane, for example, ...

Apparatuses, systems, and methods for enhancing bone or soft tissue regeneration are provided. For example, a conduit, having one or more segments, can originate at a tissue regeneration site and can have a first opening to promote physiological signals to enter the conduit and transit to a second opening that penetrates a histologically rich source of multipotent mesenchymal cells, promoting the multipotent mesenchymal cells to produce tissue regeneration response products, the response products transiting through the second opening to egress at the first opening of the conduit, and promoting tissue regeneration at the tissue regeneration site. Transit of the physiological signals and the tissue regeneration response products is promoted through physical and/or chemical means, as is promotion of the anatomical functionality of the regenerated tissue. For example, a number of the segments of the conduit can be formed at least partially from an osteoceramic material.

Professor Maher Almasri, Dean of the College will be presenting at the Dental Tribune Symposium, Istanbul, on 13 April 2019.. Details:. DT Sempozyum. The presentation will be about Our Patients Do Not Require Augmentation Anymore! Dogma vs. Reality.. Successful placement of dental implants revolves around the availability of adequate bone at the time of implantation, and resorption of the alveolar ridge adversely affects treatment success rates. Guided Bone Regeneration has been used to successfully augment implant sites, and the use of autogenous bone was previously considered the gold standard. However, donor site morbidity and other complications have led to exploration of alternative techniques. Concentrated Growth Factors have been increasingly used as graft materials, with or without other bone scaffolds, mainly because they contain the molecular proteins known as Growth Factors, which seem capable of positively influencing hard and soft tissue regeneration. Nevertheless, efforts are ...

Summary: Objective: to evaluate the efficiency of a resorbable membrane «Bio-Gide» in combination with chitosan for guided bone regeneration during the degradation under the experimental conditions. Material and Methods. The histological methods provide the study of tissue samples from 6 adult rabbits from artificial mandible through 14, 28 and 42 days after surgery. In group 1 the treatment was carried out without the use of additional materials, by a blood clot. In group 2 closing of the damaged area was produced by xenopericardial plate «Bio-Gide» in combination with chitosan. Results. It has been established that the conduct of bone wound under a blood clot causes inflammatory response on the 14th day after the operation, to the 28th day inflammation disappears and it practically does not appear on the 42nd day. Closure of the bone defect using xenopericardial plate «Bio-Gide» with chitosan causes lesser inflammatory response. In the long-term period after the surgery inflammatory ...

The researchers filled hollow nerve conduits with engineered aligned collagen gels. In the body, aligned collagen fibers help axon pathfinding, but, in the hollow nerve guides available today, the aligned collagen fibers are absent. The aligned collagen gel acts as a scaffold for axons and directs their growth. In addition, the conduits contain a substance called NGF (nerve growth factor) which, as its name implies, is essential for the growth of the nervous system. Imagine that we implanted guiding cues in the gel, which are the aligned collagen fibers, and that these guiding cues also have a treat for the growing axons, suggested Antman-Passig, like bait neatly scattered for the growing axons. An axon that reaches the gel follows these cues and finds the right direction more easily. In fact, the novel system combines several techniques for nerve regeneration, Shefi added. Axons like to grow toward these markers that can be left for them, like collagen scaffolding and NGF. The novelty of ...
