Abstract
The selection of anterior artificial teeth in edentulous patients poses a significant challenge in prosthodontics due to the loss of pre-extraction records. Skull anthropometry offers a potential alternative by providing fixed craniofacial landmarks that may correlate with tooth dimensions.
Objective: To evaluate the correlation between skull anthropometric parameters and the dimensions of anterior artificial teeth to aid in complete denture teeth selection.
Methods: This cross-sectional study was conducted on 60 dry human skulls (32 male, 28 female). Measurements included bizygomatic width (BZW), intercondylar width (ICW), and intercanine width (ICanW). The suggested central incisor width (CIW) and total anterior teeth width (ATW) were calculated using standard formulas. Statistical analysis involved Pearson’s correlation and linear regression, with a significance threshold set at p<0.05.
Results: The mean BZW was 126.4 ± 5.8 mm, ICW was 110.7 ± 4.6 mm, and ICanW was 44.2 ± 3.5 mm. A strong positive correlation was found between BZW and ATW (r = 0.82, p < 0.001) and between ICW and ATW (r = 0.74, p < 0.001). Regression analysis showed that BZW significantly predicted ATW (R² = 0.68, p < 0.001). A predictive formula was derived: ATW (mm) = 0.27 × BZW (mm) + 2.8.
Conclusion: Skull anthropometric parameters, especially bizygomatic width, are reliable predictors for estimating anterior tooth width in edentulous patients. Incorporating craniofacial measurements can enhance prosthetic esthetics in complete denture fabrication when pre-extraction data is unavailable.
