The radial forearm free flap is beneficial for reconstruction of large palatal defect with oronasal fistula.A 51-year-old male patient who had anterior palate defect including alveolus after the radiation therapy of malignant cancer on the nasopharyngeal area undertook the radial forearm osteocutaneous free flap to close the oronasal fisula and restore the alveolar arch. The small radial bone segment was fixed in the alveolar defect and vascular anastomoses were performed with facial vessels in neck. The donor site was closed with split thickness skin graft...

Implant treatment is safe and predictable with sufficient amount and quality of bone tissue. In case of severely reduced bone tissue after a tooth was lost, augmentation of such tissue is necessary before implant embedment. Retrospective evaluation covered 380 alveolar ridge reconstructions. The study material consisted of human grafts prepared by the Department of Transplantology and Central Tissue Bank, Medical University of Warsaw. Presentation of laboratory procedures in the context of physical parameters of frozen, radiation sterilised, allogeneic corticocancellous material was presented...

The aim of this study was to evaluate the final vertical gain at the deficient anterior maxillary alveolar ridges using onlay bone grafts with titanium mesh versus inlay bone grafting. This was a single institutional randomized comparative clinical trial. The study population included 16 patients, with edentulous anterior maxillary alveolar ridges (40 implant sites) who were presented and treated at the Faculty of Oral and Dental Medicine in Cairo University from September 2013 to August 2015. Selected patients were randomly divided into two equal groups...

The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental surgeons. This report describes the outcome of treatment after alveolar ridge augmentation in the atrophic posterior maxillary region via segmental sandwich osteotomy combined with placement of an interpositional autograft prior to placement of endosseous implants...

Transplantation of mesenchymal stem cells (MSCs), which possess self-renewing properties and multipotency, into a periodontal defect is thought to be a useful option for periodontal tissue regeneration. However, developing more reliable and predictable implantation techniques is still needed. Recently, we generated clumps of an MSC/extracellular matrix (ECM) complex (C-MSC), which consisted of cells and self-produced ECM. C-MSCs can regulate their cellular functions in vitro and can be grafted into a defect site, without any artificial scaffold, to induce bone regeneration...

PURPOSE: The aim of this study was to compare the complication rates of recipient sites prepared using two incision techniques: crestal and tunnel. MATERIALS AND METHODS: In this prospective study, patients underwent augmentation procedures (68 patients; 75 sites) by the same surgeon that were performed consecutively using the crestal incision technique (27 horizontal, 10 vertical; crestal group) or the tunnel incision technique (27 horizontal, 11 vertical; tunnel group)...

BACKGROUND: Incorporation of bone substitute material into the extraction socket could minimize the edentulous ridge volume loss or maximize the bone formation within the healing area. PURPOSE: The aim of the study was to test the effectiveness in maintaining the volumetric contour of fresh extraction sockets grafted with or without 2 types of porcine biomaterials and covered with a resorbable barrier. MATERIALS AND METHODS: In the present multi-center single-blind randomized control trial, 55 patients underwent 1-tooth extraction, were surveyed, and randomly allocated to control- (25 sites, nat-group) or test groups (15 sites grafted with pre-hydrated collagenated cortico-cancellous porcine bone, coll-group, and 15 with cortical porcine bone, cort-group)...

PURPOSE: Many histologic and histomorphometric studies as well as systematic reviews have shown the clinical success of the use of anorganic bovine bone (ABB, Bio-Oss) in maxillary sinus floor augmentation (MSFA). The molecular processes involved in bone healing are, however, still unknown. The aims of this study were to explore gene expression associated with bone remodeling and inflammation in MSFA sites. MATERIALS AND METHODS: The mRNA expression levels of runt related transcription factor 2 (RUNX2), receptor activator of NF-kB ligand (RANKL), osteoprotegerin (OPG), matrix metallopeptidase 9 (MMP-9), tartrate-resistance acid phosphatase (TRAP), and interleukin-1beta (IL-1β), as well as the ratio of RANKL/OPG were compared between alveolar bone of a group after MSFA with ABB and a maxillary posterior edentulous bone group...

Objective: to investigate the predictive factors of failure in bone grafts for alveolar ridge augmentation and implant surgery. Methods: we reviewed the charts of 166 patients operated between 1995 and 2014. A total of 248 grafting procedures were performed. We submitted the data to the binomial test at 5% significance. Results: grafts to gain width of the alveolar ridge (65.32%) were more frequent than sinus lifting (p<0.0001) and the number of grafts to the posterior maxilla (48...

PURPOSE: The aim of this study was to assess dimensional changes of the fresh sockets grafted with collagen sheets and maintenance of reactive soft tissue, using cone beam computed tomography (CBCT). MATERIALS AND METHODS: Tooth extractions were performed with maximum preservation of the alveolar housing, reactive soft tissue was left into the sockets and collagen sheets filled bone defects. Cone beam computed tomography were performed before and 3 months after extractions...

BACKGROUND: Several types of bone grafts are used in ridge preservation procedures. PURPOSE: To compare the healing of allografts and xenografts applied for alveolar ridge preservation. MATERIALS AND METHODS: Twenty volunteers in need of extraction of a single-rooted tooth prior to implant installation were randomized into two groups. One group received a deproteinized cancellous bovine bone xenograft embedded in a 10% collagen matrix and the other a demineralized freeze-dried cortical bone allograft...

BACKGROUND: A three-dimensionally favourable mandibular bone crest is desirable to be able to successfully implant placement to meet the aesthetic and functional criteria in the implant-prosthetic rehabilitation. Several surgical procedures have been advocated for bone augmentation of the atrophic mandible, and the sandwich osteotomy is one of these techniques. The aim of the present case report was to assess the suitability of segmental mandibular sandwich osteotomy combined with a tunnel technique of soft tissue...

The purpose of this article was to report the clinical and radiographic findings about a case of a man affected by severely atrophic maxilla to demonstrate the clinical proceedings associated with alveolar reconstruction destined for dental implant rehabilitation. The 3-dimensional augmentation of the alveolar ridge with the use of fresh-frozen bone graft, platelet-rich fibrin membrane, and titanium mesh suggests potential benefits to the development of the bone formation physiology. The treatment combination may result in an optimal prognosis and represents an option for reconstruction of bone defects...

BACKGROUND: Cortical and cancellous mineralized freeze-dried bone allografts (FDBA) are available for use in alveolar ridge preservation after tooth extraction. There are currently no data regarding the use of a combination 50/50% cortico-cancellous FDBA compared to a 100% cortical or 100% cancellous FDBA in ridge preservation. The primary objective of this study is to dimensionally and histologically evaluate healing following ridge preservation in non-molar sites using 50/50% cortico-cancellous FDBA versus 100% cortical and 100% cancellous FDBA...

BACKGROUND: Postoperative resorption of vascularized bone grafts jeopardizes the success of dental implant(s) and functional rehabilitation of the jaw. Recent evidence supports the crucial role of innervation in bone regeneration and turnover. METHODS: This study reports a new technique for simultaneous innervation of vascularized iliac flaps in mandibular reconstruction, through neurorrhaphy between ilioinguinal nerves, which innervate iliac bone, and inferior alveolar nerves or great auricular nerves...

BACKGROUND: Loss of the alveolar ridge width and height following tooth extraction is well-documented, but models to evaluate ridge preservation are neither standardized nor cost-effective. This rat model characterizes the pattern of bone turnover and inflammation after extraction and bone grafting with or without local simvastatin (SIM).
