Effect of the chin cap on biomechanical deformation of the craniofacial complex

Abstract

Using a three-dimensional finite element model, I investigated how use of the chin cap affected the distribution of stress in the mandible and temporomandibular joint. Dried human skulls were used to create the three-dimensional finite element model. Different directions of traction force that might be applied by the chin cap were input to the model. We found that different directions of traction imparted different stresses on the condyle. Using this model we were able to quantify the distribution of stress in the mandible.
