LuxaCrown Shines in Polishing Study

04 March 2020

A new study of dental restorative material polishability completed at the University of Pennsylvania School of Dental Medicine is now available on our website. 

The study, completed by Dr. Yin, Dr. Conejo and Dr. Blatz, evaluated the post-polishing surface roughness and the efficacy of polishing protocols of four dental materials, including the new LuxaCrown®️ semi-permanent crown and bridge material by DMG. The authors concluded that LuxaCrown’s surface roughness was statistically identical to that of the other three materials.

Two polishing protocols were evaluated in the study:

  1. 2-step method: 
    • Gray polisher
    • Goat hair chamois white stiff brush
  2. 3-step method:
    • Gray polisher 
    • Goat hair chamois white stiff brush 
    • Felt cloth wheel buff and composite paste 


The study concluded that the 3-step method was significantly more effective than the 2-step method.
