Comparison of Intercanine and Intermolar Widths in Dental Malocclusions Based Upon Angle Classification at Tertiary Care Hospital

Abstract

Introduction: Intercanine and Intermolar widths have been considered pivotal assessments on casts for better arch coordination.  This study aimed at comparing the intercanine and intermolar widths in Dental Malocclusion based upon Angle Classification at tertiary level hospital. This might help clinicians to better understand how changes in inter-canine and inter-molar width affect their treatment plans and retention protocols in different malocclusions.

Material and Methods:  Sample size consisted of 78 patients, 23 (29.5%) males and 55 (70.5%) females with mean age 18.52+5.27 years and 17.60+4.82 years respectively. Universal digital caliper was used to assess width at canines and molars across the arch in Angle malocclusions

Results: Insignificant differences were found for inter-canine and inter-molar widths of the maxillary and mandibular dental casts across their bases in angle class I, II and III malocclusions.

Conclusion: Intercanine width was least in Class III and widest in Class I malocclusion whereas intermolar width was least in Class III and widest in Class II malocclusion.
