A dental crown is a tooth-shaped "cap" that is placed over a tooth to restore its size, shape, strength, and appearance. Crowns can be made from a variety of materials, including porcelain, metal, and ceramic. While some dentists may make their own crowns in-house using CAD/CAM technology, most crowns are fabricated by a dental laboratory based on the dentist's specifications.
There are several reasons why a dentist might choose to make their own crowns. First, it can be more convenient and time-saving for the patient, as they do not have to visit an outside laboratory. Second, it can give the dentist more control over the quality of the crown and ensure that it meets their exact specifications. Third, it can be more cost-effective for the dentist, as they do not have to pay a laboratory fee.
