Bruxism, or teeth grinding, is estimated to affect more than 10% of the population and is becoming increasingly popular. It can cause headaches, TMD (Temporomandibular Joint Dysfunction) and even result in major teeth damage. Occlusal guards are regularly prescribed by the NHS; however, many patients reject them due to discomfort often caused by poor fit.
We set out to produce a highly accurate occlusal guard that provided a custom fit for the patient whilst remaining durable. A secondary challenge was to ensure that the time and cost required to produce the occlusal guard could compete with traditional methods. Furthermore, it was critical that the device complied with Class IIA medical classifications.
“ITERATE provide a refreshing product design perspective and are ever conscious of pragmatic, efficient and intelligent design solutions” Richard Slade, Client Services Director at Brandrefinery
A recent convergence of 3D printing and scanning technologies, as well as the market introduction of biocompatible resins makes it possible to produce Class IIA devices. We sought advice from professional Dentists in order to validate the quality of the occlusal guards produced, and to offer a critical comparison against the current methods of production.
The project outcome consisted of an optimised workflow for the production of occlusal guards that leveraged Stereolithography (SLA) technology and produced from Formlabs Biocompatible Dental LT resin with 3D model data obtained through intraoral scanning.
