The Proscan 3D non-contact surface 3D surface measurement instrument
offers fast sub-micron resolution measurement for in situ or in vitro
human enamel and dentin materials.
Dental researchers will be aware of the need for adopting new easy to
use methodology to accurately quantify the study of wear, erosion,
abrasion and porosity.
EROSION
Proscan measures the direct effect of erosion on enamel and dentine by acid foods and drinks. Small specimens are mounted onto, or into, acrylic holders for in-vitro testing. The surface profiles are measured both before and after exposure to the erosive element. Once scanned, a datum profile is produced for each sample showing sufficient detail to identify the enamel rod structure. The difference between the two scans is qualified either as height deviations or as a volume measurement.
ABRASION
Proscan is fast becoming the benchmark for enamel abrasion measurement. Favoured for its ease of use, the system easily captures the true surface profile of enamel both before and after abrasion testing. Fast, accurate surface topography allows the user to qualify the exact amount of material abraded away, expressed either as height deviations or as a volume measurement.
ATTRITION
The entire topography of occlusal, incisal and proximal surfaces are
captured through either in-situ modelling or in-vitro testing. 
Accurate
3D measurement of the polished facets formed on the cusp tip or the
flattening of the incisal edge allows qualification of wear levels,
especially where analysis over time is concerned.
SURFACE POROSITY
Sub-micron resolution allows measurements on the intercrystalline structure to be analysed. Studies into the effect of white-spot lesions reveal vital information.
SURFACE ROUGHNESS
Choose from a wide range of standard ISO and DIN surface roughness analysis tools to accurately determine the true surface texture of a material.
