Bone loss occurs when the cellular events of bone formation are quantitatively larger than bone formation. This manuscript discusses the measurement of bone loss, occurrence in the population, risk factors and consequences of bone loss. Recent developments in bone mass measurement and biomarkers have improved our ability to assess bone loss. This process is a normal concomitant of ageing. There...

introduction: the survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. implant success also is affected by the maintenance of the crestal bone around implants. the aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3...

Background: Osteoporosis is one of the uncomfortable postmenopausal symptoms. The risk of imbalanced nutrition especially traces elements and vitamins are high during post menopause and may lead to osteoporosis due to reduction of content of mineral bone. The aim of this study was to investigate the potential consequence of Selenium (Se) treatment in ovariectomized rat model with osteoporosis i...

crestal bone loss is a biological complication in implant dentistry. the aim of this study was to compare the effect of progressive and conventional loading on crestal bone height and bone density around single osseointegrated implants in the posterior maxilla by a longitudinal radiographic assessment technique.twenty micro thread implants were placed in 10 patients (two implants per patient). ...

Background and Aim: This retrospective study aimed to investigate the effects of surface roughness and implant body design on the amount of crestal bone loss around implant. Materials and Methods: In this retrospective study, dental records of 87 patients who received 139 implants were evaluated. The ITI group received 63 implants with moderate roughness, while the DIO group received 76 implan...

introduction radiographs provide unique information about the status of periodontium and permanent records of condition of bone throughout the course of the disease. interproximal images record the distance between the cementoenamel junction and the crest of the interradicular alveolar bone, more accurately. the aim of this study was to investigate the effect of different vertical angles of x-r...

different studies have reported contradictory results about the effect of osteoporosis on periodontal status. we performed this study to evaluate the periodontal status of menopausal women by methods with enough accuracy and confidence.this study was performed based on the evaluation of bone mineral density using dual energy x-ray absorptiometry in 2010. a total of 60 patients who met the inclu...
