| Abstract | ||
| Aim of the study This study was conducted to evaluate the accuracy of a new constructed 3D CBCT image–based surgical guide for miniscrew implantation . Materials and Methods Twenty five adult patients of were included in the current study (13 males and 12 females). Mandibular arch of every patient was randomly divided into : one experimental side ( miniscrews were placed using surgical guide ) and one comparison side ( miniscrews were placed conventionally without surgical guide. For both sides (experimental and comparison side); Linear measurements were recorded on the software of coronal deviations, apical deviations and vertical deviations . Also , angular measurements were recorded in both mesiodistal and buccolingual dimensions for the actual plan and the real mini screws . At the end all deviations were calculated and statistical analysis was performed. Results A significantly higher level of accuracy (lower differences from the actual value) was achieved with the surgical guide technique (p < 0.001) than hand drilling technique for all measurements . Conclusions Three Dimensional surgical guides provide a precise method for miniscrew placement into the dentoalveolar bone. | ||
