A Method for Detecting Bone Density at Different Sides and Five Sites of Mandibular Bone by New Computerized Measurements

Abstract

Introduction:The bone quality also affects the stress distribution under buccolingual load. Low density bone presents reduced stiffness and increases implant displacement. Under highest displacement, the bone is deformed, consequently higher stresses in the bone are predicted. The mental foramen is a principle factor for placing implants in the foraminal rang of the mandibular arch.Objectives: To detect and identification of mandibular bone density around the tooth and alveolar ridges at the different five sites for both male and female groups and comparing them for accurate plane and not interfere with the mental foramen and canal during surgical treatment. Material and Methods:Twelve patients ranged from 45-60 year old (6 males and 6 female) came to the Department of Prosthodontics, Alexandria University. Studied for identify the accurate nature of bone structures and detecting measurement of bone density around the implant prior to their surgical treatment. At the insertion after delivery of the denture and comparing between two gender and age groups) the evaluation of alveolar mandibular bone density using a new computerized method (Image J program) which was not used in the previous studies for prober assessment of bone height measurements. Results:The result of bone density measurements around 5 sites of mandibular bone, the mean and standard deviation of bone density measurements in right side for both male and female groups and statistical results comparison were done. There was insignificant change of bone density around the 5 sites at both groups. In the midline, there was gradual increase in the bone density from midline region to molar region and in males more than females. Conclusions:There was no statistical significant difference between the right side for female and male density at different sites, indicating more favorable stable supported overdenture with the use of accurate surgical position.
