Abstract
Progressive ridge resorption is one of the main causes of loss of stability and retention of mandibular complete dentures. 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- The subjects OPG was taken using standard radiographic procedural parameters. The measurement was done for distance ‘c’, ‘a’, ‘x’, ‘y’, ‘z’. Then 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. Results: 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. Keywords: Average alveolar bone, panoramic radiograph, mental foramen, mandibular ridge, zygomatic process, maxillary ridge. Mandibular landmarks -‘c’: is from the inferior border of the mandible to the alveolar crest. ‘a’: is from the inferior border of the mandible to lower edge of the mental foramen in dentulous mandible.
