The aim of this study was to determine the maxillary expansion index (MEI) for Pakistani population. Also to determine the sexual disparities in sum of incisors perimeter, arch width and expansion indices of maxillary arch. Hirox digital stereomicroscope was used for the fabrication of the digital models. The estimated sample size was 128 Pakistanis (64 females and 64 males; age range from18 -24 years). The perimeters of the maxillary permanent incisors, as well as intercanine, interpremolar, and intermolar arch widths, were measured on digital dental models. Significant sexual disparities were observed (***p < 0.001). There was significant difference observed in arch length and arch perimeter group of maxilla. For the prediction of ideal arch width in intercanine, interpremolar, and intermolar region to be achieved at the finishing stage, orthodontist can forecast the arch width before the initiation of orthodontic treatment. The new formula and the new indexes of arch width can be a helpful adjunct in the orthodontic treatment.

“…13 Decreased arch width is associated with a reduction in arch depth: a 3-mm reduction in arch width is known to be equivalent to a 1-mm increase in overjet. 13 Furthermore, transverse arch correction is well known to be an unstable treatment modality, 25,26 and the arch-width reduction is more likely to be unstable without extractions and is most ineffective in the posterior region. 27 The importance of the transverse dental relationships between arch width and preexisting posterior tooth inclination are sometimes overlooked by orthodontists who are more concerned about surgical jaw repositioning and facial esthetics after surgery.…”

Introduction: Maxillary premolars are often extracted to resolve incisor proclination in presurgical orthodontic treatment for severe skeletal Class III patients. The aim of this article was to compare arch-width changes and orthodontic tooth movements between maxillary premolar extraction and nonextraction modalities, and to provide an additional indication for presurgical maxillary premolar extraction according to the transverse dental arch characteristics of Class III surgical-orthodontic patients. Methods: Pretreatment and posttreatment dental casts of 55 adult Class III patients (24 nonextraction, 31 extraction) who underwent surgicalorthodontic treatment were collected. The changes in maxillary and mandibular dental arch widths were measured from the canines to the second molars. Orthodontic tooth movement was evaluated with an angulation-and-inclination measuring gauge. Results: Statistical analyses showed that intermaxillary arch congruity was attributed mainly to maxillary arch-width changes. The arch-width changes could be interpreted as the result of inclination changes in both posterior dentitions. For the arch-width change, analysis of covariance (ANCOVA) showed a significant extraction effect: the premolar extraction group's ability to accommodate arch-width change was significantly greater than that of the nonextraction group. Conclusions: The indications for maxillary premolar extraction in Class III presurgical orthodontic treatment might depend in part on the characteristics of the maxillary arch width and posterior teeth inclinations.

“…When compared to other studies, they concluded that the enlargement of mandibular arch length in the mixed dentition showed a greater relapse tendency than other directions of treatment. Kahl-Nieke, Fischbach and Schwarze (1996) studied the casts of 226 cases from the University of Cologne Department of Orthodontics files at an average of 15.7 years out of treatment (sd = 4.4 years). 14% showed an upper arch width constriction of 2 mm or more whereas 24% showed a lower intercanine width decrease of more than 2 mm.…”
