As dentists, we are responsible for the services that we provide to the patient. In the case of a filling, for example, we have full control over that process from start to finish as so can confidently stand behind the service we have provided to the patient. Where there are requirements for lab work however, we lose control over a part of the process. If there are any problems with colour, thickness, design, aesthetics, fit, or a combination of all of these things, it can undermine our clinical efforts and result in a negative experience or outcome for the patient, the clinician and the practice.
