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.
Calibration is the process of calculating a conversion factor so that the parameters measured by the recording device can be converted into eye movements. Therefore, a faulty calibration will cause the amplitude of the eye movements to be inaccurate in all of the subsequent subtests in the ENG or VNG test battery. Let us examine the calibration procedure in more detail and identify the causes that can lead to calibration errors.
