PEEK has become an increasingly interesting material in digital dental technology. Unlike traditional ceramics and metals, it is a high-performance polymer that combines low weight, good mechanical properties and high chemical stability. At the same time, it can be processed efficiently using CAD/CAM technology.
For dental laboratories, PEEK expands the range of materials available for frameworks, selected implant prosthetic components and occlusal appliances. Prefabricated PEEK blanks can be processed with modern dental milling machines, allowing complex geometries to be produced directly from digital designs.
However, PEEK behaves very differently from materials such as zirconia or PMMA. Tool selection, machining strategy and especially surface treatment must therefore be adapted to the material.
