Sažetak:
Objectives: Radiographic assessment of bone quality is of great value in planning prosthodontic treatment. Panoramic radiographs are routinely taken prior to prosthodontic treatment planning. The aim of this study was to determine the changes in bone mineral density (BMD) of the mandible in free-end saddle removable partial dentures (RPD) wearers wearing dentures of different support during a six month period. Methods: Twenty RPD patients (5 men, 15 women) participated. The BMD measurements were performed on digitised dental PRs with a 5 step copper stepwedge attached to each film cassette. Grey levels of each step of the stepwedge were transformed to optical density values and using the 3rd degree polynomial a regression formula was calculated for each digitised image to express BMD values of the measured region of interest (ROI) on the mandible in the copper stepwedge thickness equivalents. The difference in BMD values between the first and the second measurement for each ROI within gender, age groups and different type of RPD support were calculated. Results: The results revealed that the BMD value of the ROIs at the upper border of the partially edentuolous mandible in the projection of the mental foramen and at gonion were significantly different between the different denture supported RPDs (p<0.05). Conclusion: The results support the idea that under the base of mucosa borne dentures occlusal forces stimulate bone resorption, while under the base of tooth and mucosa borne dentures, occlusal forces may even cause apposition of the bone.
