BACKGROUND: Inter-foraminal implant placement poses a risk to the sublingual artery as it enters the mandibular midline lingual foramen. Lack of consensus on the source of this artery poses a dilemma to surgeons during management of haemorrhagic episodes. Determination of the exact source of this artery is therefore pivotal. METHODS: This was a cross-sectional descriptive study involving 34 adult human cadavers. The facial and lingual arteries were followed from the external carotid artery to determine whether they terminated as the sublingual artery...

This clinical report illustrates a multidisciplinary approach for the rehabilitation of a young adult patient affected by a bilateral edentulous space and an anterior deep bite. The patient required orthodontics and surgical corticotomy and implantology (both performed with a piezo device). A multidisciplinary planning approach, including orthodontics, oral and periodontic surgery, and restorative dentistry, has an important role in the final outcome of treatment. In fact a dental class I occlusion has been established only on the right side...

In oral implantology, the most serious complications occur intraoperatively or within a short period. We describe an unusual case of focal osteoporotic bone marrow defect involving dental implant in the posterior mandibular region of the adult woman. Despite the fact that this condition requires no treatment, it could lead to the displacement of the dental implant. Additionally, this case report reinforces that histopathological analysis is mandatory for precise diagnosis of the radiolucency into posterior mandibular region of the adult woman associated or not with dental implant placement...

BACKGROUND: The dimension of attached gingiva is a very important landmark in the periodontal health, and determine the function of the mucogingival unit, the progression of marginal inflammation and also affects aesthetic dentistry, orthodontics and implantology. The determination of gingival/periodontal biotype is important in dental/periodontal practice. Hence, the aim of this cross sectional clinical study was to assess the width and thickness of attached gingiva in young, periodontally healthy individuals and to provide anthropometric data in Hungary...

Implantation of a biomaterial provides an adhesion substratum both to host cell integration and to contaminating bacteria. We studied simultaneous competitive adhesion of Staphylococcus aureus in serial 1:10 dilutions of 10(8) colony forming units (CFU)/mL and human osteogenic sarcoma (SaOS-2) or primary osteoblast (hOB) cells, both 1x10(5) cells/mL, to the surfaces of titanium, polydimethylsiloxane and polystyrene. The bacterial adherence and human cell proliferation, cytotoxicity and production of reactive oxygen species (ROS) were studied using fluorometric (fluorescent microscopy and flow cytometry) and colorimetric methods (MTT, LDH and crystal violet)...

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 biodegradation were both studied in vitro through soaking in phosphate buffered saline (PBS) and in vivo by implantation in the subcutis of rats for 4, 8, 16, 26, 48 and 52 weeks...

Edentulous mandible frequently undergoes severe bone atrophy with problems of prosthetic instability. Instability of the lower denture may cause difficulties with eating and speech, ulcerations of the oral mucosa for lower denture trauma, loss of facial vertical dimension. These problems may be solved by bone augmentation of severe resorption of edentulous mandible. The aim of this short review is to describe surgical techniques for bone augmentation of the severe resorption of edentulous mandible. In this paper, we define a severe resorption of edentulous mandible as a mandibular height in the symphyseal area of 12 mm or less as measured on a standardized lateral cephalogram...
