Use of panoramic radiographs for evaluation of maxillary and mandibular residual ridge resorption:
In vitro study

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. KEYWORDS- Average alveolar
bone, panoramic radiograph, mental foramen, mandibular ridge, zygomatic
process, maxillary ridge.
