Background: Arch dimensions are very important to clinicians in orthodontics, pedodontics, prosthodontics, as well as to anthropologist. The dimensions include arch widths, arch length, and intra-alveolar width which assist in establishing proper diagnosis and treatment planning. Aims: This study aims to determine the arch dimensions in Qatari sample with different malocclusions, compare the results obtained with other previous studies and also compare the result between the different Angle's malocclusions classes. Materials and Methods: The sample consisted of 90 pairs of pretreatment orthodontic study casts selected from patients attending the orthodontic clinic. The sample was classified into three groups according to Angle's Classification as follows: Class I, Class, II, and Class III malocclusion and each group consisted of 30 pairs. The age range was between 13 and 20 years old. The intercanine width, inter-premolar width, intermolar width, and intra-alveolar width measurements were made in each dental cast using an electronic digital caliper. Independent t-test was performed for comparative analysis. Results: Descriptive statistics were presented for the three Angle's classifications. No significant difference was noted between the maxillary variables in Class I and Class III. Statistically significant difference was noticed in maxillary variables in Class II (intermolar II and inter-premolar I and II). Furthermore, significant differences were revealed in mandibular intermolar I and II, inter-premolar II, and inter-alveolar between Class III and Class I and also between Class III and Class II malocclusions. Class III malocclusion showed wider arch dimensions than that in Class I and Class II. Conclusions: The result of the present study is important to the orthodontist, pedodontist, and also to the prosthodontist and anthropologist.
