The use of properly fabricated custom-made mouthguards has been shown to significantly reduce both the incidence and severity of orofacial injury in contact sports. In this hands-on workshop participants experience the difference between vacuum-made and pressure-made athletic mouthguards. The technique for pressure thermoforming, which provides the best combination of comfort and protection, will be presented. Participants will have the opportunity to fabricate and finish a pressure-laminated mouthguard. Other uses of the demonstrated pressure technique are implant splints, bruxism splints, model duplication, orthodontic retainers, crown and bridge stents for provisional, bleaching trays and other appliances.
