Backround: This cross-sectional study aimed to quantify the proportion of 3D tooth\u2013face superimposition in young adults and examine age- and gender-related differences. Methods: In 98 dental students, intraoral MCI and facial scans were acquired under standardized protocols, processed in Mesh Mixer v. 3.5.474and Blender v. 4.3.2., and aligned to reference planes for superimposition. Residual tooth volume, reflecting tooth\u2013face correspondence, was computed via Boolean subtraction. Statistical analyses were performed in IBM SPSS Statistics 25 at \u03b1 = 0.05. Results: Total tooth volume (1,626,120.79 \u00b1 210,659.56 \u00d7 103) exceeded the superimposed volume by 285,052.34 \u00d7 103 (17.53%; 95% CI: 15.84\u201319.22%; p < 0.001), giving a superimposition proportion of 82.6%. Positive correlations between total and remaining tooth volumes were observed overall (\u03c1 = 0.448; p < 0.001), in females (\u03c1 = 0.515; p < 0.001), and in participants < 21 years (\u03c1 = 0.662; p < 0.001). Men had higher total tooth volume than women (1,706,232 \u00b1 151,086 vs. 1,583,561 \u00b1 225,978; p = 0.005). Conclusions: Volumetric analysis revealed high but incomplete dentofacial correspondence. Larger tooth volumes were associated with greater incongruence in females and younger participants, confirming volumetric size as a determinant of morphological congruence. Results highlight clinically meaningful superimposition, supporting the MCI as a reliable reference for restorative planning and esthetic reconstructions, and emphasize the value of 3D analysis for precise dentofacial evaluation and individualized esthetic planning.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
