Soft Tissue Analysis

Soft tissue structures: tissue thickness at upper lip, lower lip, Pogonion', and Menton' are depicted. Soft tissue thickness and dentobskeletal factors determine the profile. Upper lip angle and nasolabial angle are depicted. These soft tissue structures are altered by movement of the incisor teeth. Soft tissue objectives that must be considered in the treatment planning process include the following: retract, maintain, or protract upper and/or lower lip; increase, maintain, or decrease vermilion display (lip thickness); reduce lip strain, mentalis muscle strain, and interlabial gap or maintain lip competence.
