Resumo: |
Dental Implant treatment planning requires an accurate evaluation of bone site which includes density, width and height as well the relationship with anatomic structures such as maxillary sinus and mandibular canal. In order to have precise dental implant treatment it is important to have radiographies exams that would provide diagnosis, good quality images and accuracy to the treatment. The present study aims to evaluate the accuracy of conventional linear tomography and cone beam computerized tomography compared to predetermined and marked points of references in five dry mandibles and maxillas skulls. After all tomography were performed, the dry mandibular and maxilla bones were prepared for measurements thus considered real measurements. Dry bone and conventional linear tomography measurements were performed using the obtained image using the program AutoCAD® while the cone beam computerized tomography measurements were recorded using Dental Slice 2.4.3 software (BIOPARTS - prototipagem biomédica). Regarding, statistical analyses of the results, Wilcoxon non parametric statistic test showed differences between dry bones and cone beam computerized tomography (P<0,0001). There were differences between dry bones and conventional linear tomography (P< 0,0001). In addition, there were differences between cone beam computerized tomography and conventional linear tomography (P< 0,0001). Concerning the preciseness of technique, Mann-Whitney non parametric statistic test demonstrate that both tomography methods presented statistic significant differences, showing P<0,0001. Although, the cone beam computerized tomography presented with lower statistical significant differences. |
