Abstract:
Objective: Intermolar width is a key measurement which assists in treatment planning of orthodontic patients requiring
expansion as an alternate to premolar extraction. The present research was aimed at determining the mean value of intermolar
arch width (IMW) of untreated normal arch Pakistani patients visiting tertiary care dental hospital
Material & Methods: This cross sectional study was carried out using IMW measurements on plaster model of 120
untreated normal occlusion patients, at Department of Orthodontics, Faisalabad Medical University and de’Montmorency
College of dentistry, from 15-12-2016 to 15-10-2017. The non probability consecutive sampling technique was used in
this study. Data analysis was done using SPSS software 21.0.0.
Results: The mean age of the subjects was 18.23±3.75 years. The mean value of IMW in selected subjects was 45.33±3.42
mm.
Conclusion: Study results concluded that in Pakistanis, ideally align maxillary arch and occlusion can be achieved with
upper intermolar distances of 45.33±3.42 mm
