    ABSTRACT: Objectives: The aim of this study is to evaluate dental and/or skeletal changes following orthodontic treatment with Damon self-ligating (SL) brackets in non-extraction patients. Methods: Frontal and lateral images of 20 patients before and after non-extraction treatment with Damon SL brackets were traced in Dolphin Imaging. Using a computer software program (3Dceph, UIC, IL., USA) these two-dimensional images (i.e. lateral and frontal) were combined in order to generate a three-dimensional (3D) cephalogram. Bolton standards (templates) were used as controls. Bolton templates were also converted into 3D frames using 3Dceph software. Changes in both upper and lower intermolar and intercanine distances of subjects treated with Damon SL brackets were compared to those of corresponding untreated controls. Distances between both crowns and roots were studied. Also, skeletal measurements of maxillary basal bone widths were evaluated. Results: Nonparametric (Mann-Whitney) tests showed that differences in changes of the following outcome variables were statistically significant between Damon group and controls: distance between roots of upper molars (P-value<.001) (+4.59mm in Damon group vs. +.8mm in Control group) and distance between roots of lower canines (P-value= .001) (+2.19mm in Damon group vs. +.18mm in Control group). There were no statistically significant differences in changes of the other outcome variables (P-value>.01). Paired t-tests and Nonparametric (Wilcoxon) tests showed that there were no statistically significant changes in angles made by each first molar and Crista Galli-A point line and in interjugular distance (P-value>.01) before and after treatment with Damon brackets. Conclusion: With regards to transverse dimensions, a three-dimensional analysis revealed that cases treated with Damon SL brackets showed greater increase of distance between roots of upper molars and between roots of lower canines compared to untreated cases. No tipping of molars or expansion of maxillary base was observed following Damon treatment, whereas both upper and lower incisors were protruded.

    ABSTRACT: Three-dimensional cephalometric analyses are getting more attraction in orthodontics. The aim of this study was to compare two softwares to evaluate three-dimensional cephalometric analyses of orthodontic treatment outcomes. Twenty cone beam computed tomography images were obtained using i-CAT(®) imaging system from patient's records as part of their regular orthodontic records. The images were analyzed using InVivoDental5.0 (Anatomage Inc.) and 3DCeph™ (University of Illinois at Chicago, Chicago, IL, USA) software. Before and after orthodontic treatments data were analyzed using t-test. Reliability test using interclass correlation coefficient was stronger for InVivoDental5.0 (0.83-0.98) compared with 3DCeph™ (0.51-0.90). Paired t-test comparison of the two softwares shows no statistical significant difference in the measurements made in the two softwares. InVivoDental5.0 measurements are more reproducible and user friendly when compared to 3DCeph™. No statistical difference between the two softwares in linear or angular measurements. 3DCeph™ is more time-consuming in performing three-dimensional analysis compared with InVivoDental5.0.
