<![CDATA[Residual ridge resorption and remodeling directly affect the function of removable prostheses which relies greatly onthe quantity and architecture of jaw bones. The purpose of this study was to assess the remaining bone height level inrelation to some pathophysiologic factors that may affect on the resorption process. The factors involved in this studywere Diabetes mellitus, periodontitis, menopause, and edentulousness time (more than 10 years). Maxillary andmandibular bone height on 115 dental panoramic radiographs belonged to full edentulous patients were measured andcompared to 35 controls using MB Ruler software. The soft images were collected using the radiographic machines inthe faculty of dentistry. The measurements included maxillary middle anterior and lateral bone heights, middlemandibular dimension, right and left mental bone heights. The results showed that women with completely edentulousarches showed relatively higher rate of bone resorption than men, and control group. Indian patients also demonstratedhigher bone resorption rate, particularly on the mandible, followed by Chinese and Malay. In regard to different healthconditions, edentulousness time for more than 10 years showed the minimal bone height reduction that affected mainlythe mandible sides compared to other conditions and the control group. On the sides of maxilla, periodontitis exhibitedhigher effect on the residual ridge resorption rather than other studied conditions. However, on the middle of maxilla,menopause was associated with maximum bone resorption compared to the others. As conclusions, residual ridgeresorption in completely edentulous patients may be influenced by gender, race and patient’s health conditions.]]>
