CDS bite splints can be constructed for the upper or lower arch. These clear appliances are a one-part or two-part construction. For the CDS Easy-Guard hard-soft appliance, there is a hard external surface and a soft internal surface for improved patient comfort. The hard and soft Easy-Guard options have only one part, providing hard, solid protection or a soft alternative. These bite splints are recommended for patients that brux and those with cosmetic restorations.
