Heat Generation During Ore Milling

Milling Burs - Articon

Milling Burs - Articon

When processing plastics such as PMMA or PEEK, suppression of heat generation during milling plays a crucial role. Processing these materials with standard cutting tools usually results in strong heating of the dental milling tools. The resulting melting of plastics has a detrimental effect on the surface quality and the fit of restorations.
