Outline of Final Research Achievements

In orthodontic treatments, developing a mathematical model to predict the effects of facial aging using skin viscoelasticity and three-dimensional facial topography leads to effective treatment planning that reflects facial aging. Thus, the present study aimed: (1) to analyze the three-dimensional facial soft-tissue topography and skin viscoelasticity at rest and during facial expressions in two age groups (young adult and elderly groups), (2) to clarify the vector elements (or mathematical expressions) that can effectively detect facial aging, and (3) to develop a mathematical model to predict the effects of facial aging using the aforementioned vector elements.
