Sažetak
The aim of the study was to measure the bone mineral density (BMD) on regions of interest (ROIs) on maxillary alveolar ridges close to the implant and to compare them with BMD ROIs on the other sites of the bone. In cases if there were other remaining teeth in the maxilla the aim was also to compare BMD of ROIs close to the implants with the ROIs close to the remaining teeth. For this reason periapical radiograms with a 10 steps copper stepwedge attached to each film were made in 10 patients with 23 ITI implants in maxilla. Films were processed together and were digitised. Grey levels of each step were transformed to optical density values and using the 3rd degree polynomial the regression formula was calculated for each image. All the measured values (ROIs) were expressed in actual copper stepwedge thickness equivalents using the calculated regression formula. Comparison of BMD close to the implant in comparison to BMD close to the remaining teeth shows the rate of success of osseointegration. This method may help dental surgeon to assess the success of osseointegration of the implants and even to assess the quality of bone prior to the treatment.
