kinematic strain-free tooth movement

Virtual motion of a tooth among its antagonists and its neighboring teeth by treating the tooth as a rigid body (solid). Kinematic refers to the concept that a tooth is not allowed to interpenetrate another tooth and thus its motion is defined as part of a mechanism comprised of its antagonists and neighbors and constraints of the occlusal surface and arch form. Strain-free refers to the concept that a tooth is not allowed to deform. Strain is caused by the deformation of a body (tooth) over part or all of its volume. Kinematic strain-free tooth movement is achieved by requiring the tooth to act as a rigid body experiencing no deformation under motion. Used in some complete denture digital design software.
