UNIQUE MEASUREMENT TECHNOLOGY
At the heart of the technology is a patented Confocal multiplexing sensor with up to 0.005µm resolution. The technology works well on human enamel and dentine for two reasons:
Safe white light is transmitted through a lens, which has carefully manufactured spectral aberration built in. It is this effect that takes the white light and divides it into the full spectral field, focusing each different colour frequency at a slightly different point through a defined measuring range. When an object is placed within this range, only one particular colour frequency reflects back from the surface.
This information passes back into a processor where a spectrometer analyses the signal and converts it to a measurement. Proscan combines these measurements with the precise location of a moving X and Y linear table, giving three co-ordinates from which a three dimensional profile is created.
The Chromatic Measuring Technique
Proscan measures the direct effect of erosion on emanel and dentine by acid foods and drinks. Small speciments 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.
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 eith as height deviations or as a volume measurement. (Ref ISO 11609:2010)
The entire topography 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.
Sub-micron resolution allows measurements on the inter-crystalline structure to be analysed. Studies into the effect of white-spot lesions reveal vital information.
