About PMMA discs
PMMA, polymethyl methacrylate, is used in dentistry for artificial teeth, denture bases, retainers and provisional crowns. Milled PMMA is used for long-term provisional restorations, up to one year. The FDA defines temporary crown and bridge resin as a material such as polymethylmethacrylate for a temporary prosthesis used until the permanent restoration is made, Class II (21 CFR 872.3770).
A CAD/CAM block or disc is a prefabricated piece of material from which a restoration is milled by a computer-controlled machine. The Glossary of Prosthodontic Terms defines CAD-CAM as the computer-controlled subtractive fabrication of a three-dimensional object, used to produce crowns, veneers, inlays, onlays and other prostheses. By material, a systematic review groups CAD-CAM materials into silicate ceramics, oxide ceramics, composite resins, PMMA, PEEK, polymer-infiltrated ceramic network materials and metal.
How the types of block and disc differ
- Zirconia discs and blocks — The strongest of the materials here, with aesthetics somewhat below the silicate ceramics. Milled oversize and then sintered, because it shrinks in the furnace.
- Hybrid ceramic blocks — Part ceramic and part polymer, where zirconia is all ceramic. Resin block composites can be used for permanent restorations.
- PMMA discs — A polymer for provisional work, where zirconia and hybrid ceramic are for permanent restorations.
- Wax discs — Not a final material: the milled wax is a pattern that is removed from the mould, usually by heat.
What to look at when choosing a zirconia disc
Yttria content: the cubic phase and the translucency rise with the yttria concentration. More cubic phase improves translucency and lowers strength.
Grade names: with 3 to 8 mol% yttria the material is called partially stabilised zirconia (PSZ), and at about 3 mol% it is close to fully tetragonal (TZP).
Colour: a zirconia restoration is coloured either by using a pre-coloured block or by immersing or brushing the white restoration with colouring solution.
Sintering: the optimum sintering temperature range given in the review is 1350 to 1550 °C.
