When it comes to dental restorations, dental prostheses are usually the last alternatives. These restorations are only used when a tooth is severely damaged or even when they're lost.
In the case of crowns and bridges, the dentist usually needs to make a temporary restoration. This specialized type of restoration protects the tooth while the final restoration is being crafted. Furthermore, they help identify every defects or detail that must be fixed before the restoration is made.
These temporary restorations are usually made of an acrylic polymer. Although the dentist can make the restoration by mixing the polymer with the monomer, using a dental PMMA block makes the process easier and more accurate.
A dental PMMA block is a solid piece of a specialized acrylic material that can be used to mill temporary restorations. Pmma stands for Poly Methyl Methacrylate. This is an acrylic material used in temporary dental restorations.
Dental PMMA blocks are used with CAD/CAM technology to produce a high-quality restoration.
To do so, the dentist has to design the restoration on a computer using CAD software. Afterward, the dental PMMA block must be introduced on the milling machine. When given the order, the machine cuts and wears down the block. Therefore, shaping it as the intended restoration.
Dental PMMA blocks come in different colors to match the patient's aesthetics. Also, they have excellent physical properties.
