About hard splint blanks
Hard splint blanks are rigid sheets that are thermoformed over the model of the teeth to make a hard splint or night guard. A splint has to be mechanically stable to withstand high occlusal forces.
An occlusal splint is a removable appliance worn over the teeth. The device should be mechanically stable to withstand high occlusal forces, chemically stable and biocompatible. The Glossary of Prosthodontic Terms describes a night guard as a removable device, usually of hard polymethylmethacrylate, that covers the occlusal and incisal surfaces of all the teeth in one arch.
How hard, soft and dual splint materials differ
- Hard Splint Blanks — Rigid sheet for a hard splint.
- Soft Splint Materials — Flexible sheet, or a laminate with a soft inner layer.
- Soft & Dual Blanks — Soft sheet, or soft bonded to hard.
- Splint Sheets — Thin sheet for temporary splints and surgical trays.
- Athletic Mouthguard Materials — EVA mouthguard material and mouthguard laminates.
- Mouthguard Blanks — The same EVA material and laminates, filed as blanks.
- Mouthguard Sheets — The same EVA material and laminates, filed as sheets.
What to look at when choosing a splint material
Material and thickness: in a study of thermoforming foils, both the type of material and its thickness affected weight change, colour stability and elastic modulus.
Properties change in forming: one study concluded that the physical and mechanical properties of thermoplastic materials should be evaluated after thermoforming.
Size and gauge: sheets are listed by thickness, by shape (5 inch square or round) and by pack count.
