Purpose. The aim of this study was to verify the prevalence of alveolar bone loss in Brazilian adolescents through the interproximal X-rays analysis. Methods. Bilateral and standardized interproximal (bitewing) X-rays were performed in 15-year-old adolescents (n = 326), and the processing of films and measurements of alveolar bone levels were accomplished by a single examiner. A distance betwee...

The association between skeletal bone mineral density (BMD) and mandibular alveolar bone mass has been reported to be rather weak, probably due to local functional factors. Many new investigations are therefore focused on assessing the mandibular bone structure. No long-term structural alterations have been reported in human mandibular bone with the exception of alveolar crest changes related t...

osteoporosis is a skeletal disease characterized by reduction in bone mass and micro architectural changes in the bone, which leads to increased bone fragility. the gold standard for the diagnosis of osteoporosis is the measurement of bone mineral density (bmd) by dual energy x-ray absorptiometry (dxa). periodontal disease is a chronic destructive disease which can occur in adults, young people...

The mandible is a unique bone with a two-layered structure comprising the alveolar area that holds the teeth and the base of the mandible. It is subjected to various types of mechanical stress. The mandible has a specialized structure enabling it to sustain localized stress exerted by the teeth. When teeth are lost, the alveolar area is quickly resorbed, and the internal structure of the mandib...

PURPOSE The aim of this study was to assess the efficacy of alveolar vertical distraction osteogenesis and autogenous bone grafting in terms of bone gain, bone resorption, and implant survival and success rates and investigate the relationship between bone gain and resorption after alveolar vertical distraction osteogenesis. MATERIALS AND METHODS A systematic search was done using MEDLINE, EM...

Decoronation of ankylosed teeth in infraposition was introduced in 1984 by Malmgren and co-workers (1). This method is used all over the world today. It has been clinically shown that the procedure preserves the alveolar width and rebuilds lost vertical bone of the alveolar ridge in growing individuals. The biological explanation is that the decoronated root serves as a matrix for new bone deve...

Periodontitis is an inflammatory disease characterized by loss of connective tissue and alveolar bone, and osteoporosis is a common disease characterized by a systemic impairment of bone mass and microarchitecture. To date, the association between periodontitis and osteoporosis has remained to be fully elucidated. In the present study, an experimental rat model of periodontitis was used to expl...

Mini-implant loss is often associated with physical and mechanical aspects that result from choosing an inappropriate placement site. It is worth highlighting that: a) Interdental alveolar bone crests are flexible and deformable. For this reason, they may not offer the ideal absolute anchorage. The more cervical the structures, the more delicate they are, thus offering less physical support for...

PURPOSE In this study, we performed alveolar bone grafting with autologous iliac cancellous bone incorporation with platelet-rich plasma (PRP) and evaluated its efficacy in osteoregeneration. MATERIALS AND METHODS Seven alveolar cleft patients with adult dentition (average age, 16.1 years) underwent iliac bone grafting with PRP. Quantitative evaluation of regenerated bone was made with 3-dime...
