There was no statistically significant difference between the groups and identified time periods in terms of the overjet, overbite, maxillary and mandibular intercanine widths, intermolar widths and arch lengths. In addition, although the maxillary and mandibular irregularity indexes increased from the post-treatment to the post-retention phase, the difference was not statistically significant.
A study reported an increase in inter-first premolar width, inter-molar width and an insignificant decrease in arch length and no change in arch depth.12 Another study reported an increase in the inter-first permanent molar width13 while another reported an increase in the inter-first permanent molar width among males and no change in females.26 Regarding arch length, several studies have reported a decrease in their respective samples.16,27,28
(3) Through the methods combination of similar simulations and field measurements of drilled holes, the hanging arch lengths in the goaf of 6.4 m, 22.1 m, and 29.6 m, high above the coal bed, were determined to be 9.5 m, 11.6 m, and 14.1m, respectively.

Impacted maxillary canines can lead to root resorption of adjacent teeth, transposition of canines, decrease in arch length or development of cystic masses causing infection and pain.9,10 Diagnosis of impacted canine is done both clinically and radiographically.
Furthermore, MASDO is effective in increasing alveolar arch length and correcting anterior crossbite in patients with a cleft lip and palate [13,14,16].
The patient had tooth size arch length discrepancy (TSALD) and according to Bolton analysis there was mandibular anterior tooth material excess.
This introduces an imbalance to the maxillary and mandibular dental arch length.1 Treatment for the replacement of the missing tooth depends on a number of factors, such as arch length, the number of missing teeth, patient profile and smile line.
