conclusions the outside diameter/inside diameter ratio at the metaphyseal/diaphyseal junction of the distal radius on ap radiographs is suitable for use as a predictor of distal-radius bone density. further studies should be performed, and clinical utility evaluated. results the mean bmd was 0.559 (sd = 0.236) g / cm2. the mean outside diameter/inside diameter ratio was 1.24 (sd = 0.013); the r...

accurate measurements of physical characteristics of bone are essential for diagnosis, assessment of change following treatment, and therefore, indirectly, for evaluation of new forms of therapy. this is particularly true of osteoporosis and aging skeleton, in which fractures occur easily. methods: in this study an ultrasonic system was set-up and calibrated on plexiglas tubes of variable thick...

Abstract Background and Aim: This study aimed to assess the bone thickness at the interradicular spaces in the anterior mandible on cone-beam computed tomography (CBCT) scans of patients to find appropriate sites for mini-implant and miniscrew placement. Materials and Methods: This analytical cross-sectional study was conducted on 161 CBCT scans of patients (98 females and 63 male...

objectives: the purpose of this study was to determine buccal bone and soft tissue thicknesses and their correlation in the maxillary anterior region using cone beam computed tomography (cbct). materials and methods: in this cross sectional study, 330 sound maxillary incisors in 60 patients with a mean age of 37.5 years were assessed by cbct scans. for better visualization of soft tissue, patie...

PURPOSE The aim of this study was to determine the relationship between buccal bone thickness and gingival thickness by means of a noninvasive and relatively accurate digital registration method. METHODS In 20 periodontally healthy subjects, cone-beam computed tomographic images and intraoral scanned files were obtained. Measurements of buccal bone thickness and gingival thickness at the cent...

introduction: knowledge of the presence of the alveolar antral artery in the lateral maxillary sinus wall is essential for surgeons who operate in this region. the purpose of this study was to investigate the correlation between alveolar antral artery diameter and lateral maxillary bony wall thickness in dentate patients.   materials and methods: thirty five cone-beam computed tomography (cbct)...

objective: implants are being used in orthodontics as a reliable mode of anchorage. among other factors, the cortical bone thickness plays a major role in determining the stability of these implants. the objective of this study was to study the relationship of various arch forms and the cortical bone thickness and to determine if the cortical bone thickness varies between various arch forms. th...
