objectives : bone assessment is essential for diagnosis, treatment planning and prediction of prognosis of periodontal diseases. however, two-dimensional radiographic techniques have multiple limitations, mainly addressed by the introduction of three-dimensional imaging techniques such as cone beam computed tomography (cbct). this study aimed to assess the accuracy of cbct for detection of marg...

Background: Osteoporosis one of the postmenopausal symptoms is characterized by bone loss. There is a link between excessive reactive oxygen species (ROS) formation, estrogen deficiency due to cessation of ovarian function and bone loss. Free radicals are responsible for causing osteoblast apoptosis and reducing osteoblastogenesis in bone remodeling. Vitamin E is a potent antioxidant with the a...

background radiography is as a part of periodontal examination. early detection of periodontal disease is important in the prevention of tooth loss and patient’s general health. objectives the objective of this study was to compare diagnostic accuracy of cone-beam computed tomography (cbct) with digital direct intraoral radiography, in assessment of periodontal osseous lesions. materials and me...

the biological interaction between the jaw bones and dental implant is fundamental for the long-term success of dental implant placement. nevertheless, the insufficient bone volume remains a major clinical problem, especially in case of immediate dental implant. using a canine model, the present study proves the regenerative potential of adipose- derived stem cells (adscs) to repair peri-implan...

objective: vertical bone loss evaluations in the nobel biocare replace® select tapered tm implant system in the human after one-year loading time. materials and methods: this retrospective cross-sectional study was performed on 31 patients (14 men, 17 women; mean age, 60.39 years) receiving 170 implants (mean, 5.48 for each patient) of groovy and non-groovy designs in the nobel biocare replace®...

o bjectives: the aim of the present randomized clinical trial was to evaluate marginal bone loss around two types of implants modified at the neck area: nobel active and nobel replace groovy, both manufactured by nobel biocare. materials and methods: a total of 25 nobel active and 21 nobel replace groovy implants were included in the present study. the implants were placed based on the relevant...

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...
