Craniofacial morphology in patients with impacted canine: a case control-study

Area of Science:

• Dentistry
• Orthodontics
• Cephalometric analysis

Background:

• Maxillary canine impaction is a common orthodontic concern.
• Cephalometric analysis aids in understanding craniofacial relationships.
• Identifying risk factors for canine impaction is crucial for early intervention.

Purpose of the Study:

• To evaluate cephalometric predictors of maxillary canine impaction.
• To compare craniofacial variables between impacted and non-impacted canine groups.

Main Methods:

• Retrospective study of 182 Caucasian patients (mean age 12.4).
• Comparison of 90 patients with impacted canines versus 92 with normal eruption.
• Analysis of multiple cephalometric variables including SNA, ANB, and Go-Me distance.

Main Results:

• Impacted canine group showed increased Go-Me distance, SNA angle, and A1s-Pt angle.
• A decrease in A-SN distance and SP-Cl distance was observed in the impacted group.
• Statistical significance was determined using t-tests and Mann-Whitney tests (P<0.05).

Conclusions:

• Increased mandibular length (Go-Me) and SNA angle are associated with canine impaction.
• Reduced A-Sn distance and interclinoid distance (SP-Cl) are indicators of impaction risk.
• Cephalometric analysis can help identify individuals at risk for maxillary canine impaction.
