While traditional veneers are much thicker, requiring the grinding down of your original tooth structure, Lumineers are so thin that little to no tooth reduction is necessary. Additionally, the durability of Lumineers allows them to resist wear and remain resilient to last over 20 years.
CALIBRATION - An operation that, under specified conditions, in a first. step establishes a relation between the quantity values with  measurement. uncertainties  provided by measurement standards and corresponding. indications with associated  measurement uncertainties  and, in a second.
Traceable Calibrations and Reference Standards. Here in the USA, most literature for flow instrumentation and/or instrumentation calibration services includes a statement explaining that the deviceâs calibration is NIST-traceable. Other countries may see similar statements such as PTB-traceable, or INMETRO-traceable calibrations.
