Do You Outsource Lab Work or Send Work Offshore?
If the answer is yes, find another lab. The only way for a laboratory to really know how restorations are being fabricated is if they make them on-site. If lab work is routinely being sent elsewhere or to an overseas lab, no one really knows what is happening or if there is any type of quality control. You may not be getting the quality materials that you paid for.
Outsourcing also sets up a chain reaction of events should your restoration not fit correctly. Who is responsible? With outsourcing, the dentist will never be able to communicate directly with the fabricator. When laboratory mistakes happen, your patient ultimately loses and they will blame you.
