About temporary crown material
A temporary crown and bridge resin is a material such as polymethylmethacrylate used to make a temporary crown or bridge, for use until the permanent restoration is made. The FDA classes it as a Class II device (21 CFR 872.3770). These materials divide into methacrylate resins, supplied as a liquid and powder and mixed by hand, and composite resin materials, supplied as two pastes and mostly automixed. Methacrylate resins set by a chemical reaction, while the composite-based ones are self-curing or dual-curing.
An interim prosthesis is a fixed or removable prosthesis made to improve appearance, stability or function for a limited period, after which a definitive prosthesis replaces it. The shelf holds both kinds of material, with the acrylic powders and liquids, the stain liquids and the glaze used to finish a provisional.
How the two kinds of material differ
A review lists the drawbacks of the acrylic as high polymerisation shrinkage, release of residual monomer and ready staining. The same review notes that its contraction and the heat given off while it sets can interfere with the state of the mouth.
Materials containing no methyl methacrylate were introduced to reduce tissue toxicity and thermal irritation. In one laboratory study the self-curing acrylic gave off significantly more heat than the bis-acrylic composite, and took about twice as long to reach its peak temperature.
What to look at when choosing
Span: in a study of provisional materials, fracture of a long span restoration under considerable chewing force was described as more likely than fracture of a short span. How long it stays in: a review notes that provisionals are usually worn for a short time, but complex rehabilitations can keep them in place for a prolonged period.
What it has to do while it is in: cover exposed dentine, prevent unwanted tooth movement, maintain function, allow oral hygiene and prevent gingival overgrowth. Provisional restorations also allow the appearance, the occlusal vertical dimension and the new occlusal scheme to be tested before the final work.
