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.
What's the difference between adjust and calibrate? Prover is a device which helps us to know the 'K' factor (multiplication factor) for a metering unit (flow meter). Calibration is the process in which we minimize the error in the measuring device using a calibrator or prover.
