Abstract

Introduction: Ridge resorption is the major reason of mandibular complete denture losing its stability and retention. The location of the mental foramen can be identified easily on panoramic radiographs, and radiographic examinations are considered an important component of Prosthodontics diagnostic and treatment planning. Also, the location of maxillary landmark is important to known how much resorption is there. Aim: To determine the average ratio of bone height with nearest constant anatomical landmarks in maxilla and in mandible. OBJECTIVE- To find out the association between radiographic findings & prosthodontics, such as measurements of the amount of resorption and the variation in the treatment planning of edentulous patients. Methods: In this study OPG machine- Kodak C 8000 and Software to calculate the distance- Screen calipers v2.1 is used. 100 patients OPG was taken in this study. Major inclusion parameters included were presence of mandibular premolars and molars, minimal ridge resorption and clear radiographic landmarks visible on the OPG. After which the landmarks and specific structures were marked on the OPG. Then measurement was done for distance ‘c’, ‘a’, ‘x’, ‘y’, ‘z’. Lastly, the calculations from measurements were done to calculate the ratio of c/a, to calculate the ratio of x/y, to calculate the ratio of x/z. Result: The descriptive statistics was done. The C/a ratio mean is 2.71 ± 0.31. The X/Y ratio mean is 1.49 ± 0.34 and the X/Z ratio mean is 1.51 ± 0.24. Conclusion: This ratio can be assessed in edentulous patients and then their further treatment plan can be decided according to the ratio. The implant placement can be assessed by using the measurements in this study.
