Laboratory certification does not offer concrete guarantees of consistent high quality of products or services. It does, however, identify, for the dental profession, a competency and acceptability factor on which to base a predication of performance by the laboratory. Also, laboratory certification establishes a framework within which the dental laboratory industry can work to continue upgrading its facilities and personnel, demonstrates the concern of certified laboratories for continuing competence, and indicates to government and third-party payers a willingness to develop standards endorsed by the industry.
