Outline of Final Research Achievements |
We analyzed three dimensional facial soft tissue changing between before and after mandibular setback surjery using facial-dental cast hard and soft tissue three dimensional model originaly developed. We used multiple regression analysis for analizing soft tissue changing to find useful explanatory variable. Result of 5 cases, about explanatory variable, hard tissue changing was selected at all region, and soft tissue thickness before orthognathic surgery was selected at almost all region. Furthermore,upper lip tention value was selected at under nose region, and lower lip tention value was selected at upper and lower lip region. R2 was 0.10-0.39 at upper 4 region, 0.51-0.60 at lower 4 region. and was higher than single regression analysis analized before.
