Introduction: To analyze the skeletal features of patients with maxillary canine impaction. Materials and Methods: Pretreatment lateral cephalograms of 30 patients in buccally displaced canine group (BDCG), 15 in palatally displaced canine group (PDCG), 30 in impacted canine group (ICG), and 50 in control reference sample (control group [CG]) were used to analyze the selected dentoskeletal characteristics. One-way analysis of variance was used to identify the differences in angles among the four groups (BDCG, PDCG, ICG, and CG). The differences in the relative distribution among the groups were tested by Pearson's Chi-square test. Independent samples t-test was used to test the significance of differences between the two groups. Results: In BDCG, retrognathic maxilla, tip up maxilla, retrognathic mandible, skeletal Class II, and horizontal growth pattern were the significant factors. In PDCG, skeletal Class II and hypodivergent were significant factors. In ICG, retrognathic maxilla, retrognathic mandible, hypodivergent relationships are poorly significant factors. The nasolabial angle and Steiner's S line were insignificant in all groups except the ICG where acute nasolabial angle is poorly significant. Conclusion: When compared to controls, canine impaction(s) revealed a trend toward retrognathic maxilla, retrognathic mandible, skeletal Class II, and hypodivergent skeletal relationship.
