Polished Ceramic Plate

Dental esthetics is becoming more important for dental patients in recent years. Ceramics are commonly being used for tooth restoration due to their better chemical inertness and mechanical strength.

It has been demonstrated that the surface roughness of polished ceramics is linked to the crack formation, so this feature needs to be thoroughly investigated.

Nanosurf Nanite AFM

A Nanite AFM operated in contact mode was used to record the measurement. The measurement was conducted in a noisy environment with no vibration insulation.

The AFM image (Figure 1) compares a polished ceramic surface to an unpolished one where the RMS roughness is 310 nm and 570 nm, respectively.The polishing scratches are clearly visible in the unpolished area.
