ABSTRACT:Purpose: To determine the variations in mandibular arch morphology among different Anglesâ€™ Classes of malocclusion using canine width to depth ratios.

Material and methods: Canine width and depth linear measurements were performed on 93 study models to determine the arch form. Canine width to depth rations were calculated and compare with occlusal patterns and between genders.

Results: The most common class was Class I (54.8%), more females (p<0.05) had Class I and II than males

Females significantly (p<0.05) recorded higher canine width: depth ratios, they had tapered and ovoid arch forms (p<0.05), opposite to males who had square arches (p<0.05).

In females, tapered and ovoid forms predominated in Classes I and II arches. However, square form was recorded in males with Class III relations.

Conclusion: The most common arch form in Class I was the ovoid, tapered form in Class II, and square form in Class III subjects.
