Canine tip marker: a simplified tool for measuring intercanine distance.

Area of Science:

• Dental Prosthetics
• Anthropometry
• Oral Anatomy

Background:

• Accurate selection of anterior teeth is crucial for successful denture prostheses.
• Facial landmarks offer potential guides for tooth selection in prosthodontics.

Purpose of the Study:

• To evaluate the correlation between intercanthal width and interalar width with intercanine distance.
• To determine the predictive value of facial measurements for maxillary anterior tooth selection in North Indian populations.

Main Methods:

• A study involving 100 North Indian adults (50 males, 50 females) aged 17-21.
• Measurements of intercanthal width, interalar width, and intercanine distance using a digital caliper and canine tip marker.
• Statistical analysis using Student's t-test to assess correlations.

Main Results:

• A significant correlation was observed between interalar width and intercanine distance in both male and female groups.
• Interalar width demonstrated a higher correlation with intercanine distance compared to intercanthal width.
• Intercanthal width showed lower correlation values with intercanine distance in both genders.

Conclusions:

• Interalar width is a reliable anthropometric guide for selecting maxillary anterior teeth in denture fabrication.
• Facial measurements, specifically interalar width, can aid in achieving aesthetically and functionally appropriate tooth selection.
• The findings support the use of interalar width as a practical tool in prosthodontic treatment planning.
