This technique describes the additive manufacture of a dual-material occlusal device using information captured with an intraoral scanner and a vat-polymerization printer. The resulting occlusal device combines a resilient intaglio with a hard resin exterior surface, leading to improved patient acceptance and comfort, better fit, and minimal adjustments required for fit.
A technique to additively manufacture an occlusal device by using a completely digital workflow is described. Using a computer-aided design program, information captured with an intraoral scanner was used to additively manufacture a dual-material occlusal device by using a vat-polymerization printer. This technique allows for the combination of 2 different materials, resulting in an occlusal device with a resilient intaglio and a hard resin exterior surface. Advantages of the resulting occlusal device compared with a single-material device include improved patient acceptance and comfort, better fit, and minimal adjustments to ensure fit.
