Paget’s disease is a chronic non-metabolic bone disorder that is characterized by increased bone resorption, bone formation and remodeling. This unbalanced process may lead to osseous deformities, structural weakness and altered joint biomechanics all of which can make surgical reconstruction difficult. Although few patients with Paget’s disease ever require surgical treatment, successful surgi...
It appears that until bone graft has not achieved 100% success, intraradicular diseases remain controversial and therefore, different treatment plans are suggested for them. Treating intraradicular diseases depend on many factors: maxillary molars are more prone to bone loss and have worse prognosis. To assess prognosis more carefully these factors should be considered: 1) bone loss: its apical...
The geometric shape of dental arch (square, tapering, ovoid) is an important factor in stress distribution pattern around dental implant. The aim of this study was to evaluate the role of arch form and the amount of bone loss (normal, moderate, high) in stress distribution around dental implant by considering different load direction. Three arch forms square, ovoid, and tapering with three diff...
background: ankylosing spondylitis (as) is an inflammatory rheumatic disease that leads to a progressive ankylosis of vertebras and ossification of paravertebral ligaments. bone loss and osteoporosis are amongst the important complications of as, treatment of which is a challenging issue. objectives: this study aimed to clarify the effect of alendronate on the prevention of bone loss in patient...
OBJECTIVE This study used con-beam computed tomography (CBCT) to investigate the prevalence and severity of alveolar bone loss in middle-aged (40-59 years) Chinese with chronic periodontitis. MATERIALS AND METHODS The study group comprised 145 dentate individuals aged 40 to 59 years residing in China who suffered from chronic periodontitis. CBCT and the application of NNT software were used t...
