Using the quantitative analysis of dental radiograms by means of AL-equivalent Images, we can observe easily the progress of clinical cases. Therefore, we compared the inserted Al2O3 (Bioceram®) implants with Ti (Bonefit®) implants by the AL-equivalent Images.
11 male and 12 female partial edentulous patients, who were treated with A12O3 (Bioceram®) implants, and 5 male and 14 female partial edentulous patients, who were treated with Ti (Bonefit®) implants, were examined in this study.
Dental radiograms were pictured before the implantation and 1, 6, 12 and 18 months following implantation.
We observed the alveolar bone which was between implants or implants and natural teeth, which were the lower half of the implant, equivalent to the alveolar bone which was between the 1 st and 2nd mandibular molars.
The average and SD of the computed AL-equivalents varied by age and between male and female.Thus, a Z-score was used for normalization of these variations. We tested the difference between each group by the t-test.
In this study we observed Al2O3 (Bioceram®) implants and Ti (Bonefit®) implants, and we found that after implantation the observed bone of both types of implants was high AL-equivalent. But the AL-equivalent of observed bone of Ti (Bonefit®) implants returned to the state before implantation soon.
