Abstract:

Background Non-extraction treatment protocols are better accepted by patients as well as clinicians. Among the techniques and mechanics with the potential to facilitate non-extraction treatment includes headgears, fixed sagittal correctors, transverse expansion screws and self-ligating systems. Objectives To evaluate the intra-arch dimensional changes in moderate crowding cases, treated non-extraction with a passive self-ligating (Damon ۳MX) appliance using digitized models and lateral cephalograms. Methods A total of ۲۰ patients (age group of ۱۵ - ۱۸ years) who had undergone non extraction orthodontic treatment with the Damon ۳MX appliance were selected. All the pre-treatment and post-treatment dental stone models of maxillary and mandibular arches were scanned using ۳D digital scanner (Maestro ۳D, Greatlakes, USA) and were converted into digital models. Various parameters undertaken were measured digitally on the computer in millimetres. Cephalometric tracings of pre and post treatment cephalograms were performed using digital cephalometrics (Nemo Ceph, version ۶.۰, Spain). Statistical analysis was performed using t-test. Results More transverse expansion was observed in the region of ۱st and ۲nd premolars as compared to the inter-canine and inter molar region in maxillary and mandibular arch. However a decrease in arch depth was observed in maxillary arch but arch depth of mandibular arch was found to be increased. There was significant increase in anterior proclination in both maxillary and mandibular arches. Conclusions Passive self-ligating system causes a significant increase in transverse width in both maxillary and mandibular dental arches.
