Answer :
Final answer:
A dental laboratory technician requires an accurate impression of the prepared tooth, details on occlusion, and shading information to fabricate a custom dental crown.
Explanation:
Before a dental laboratory technician can fabricate a crown, several preliminary steps must be completed by a dentist. The crown fabrication process usually begins with a dentist preparing the tooth by removing any decay and shaping it for the crown. Afterward, an accurate impression of the prepared tooth and surrounding teeth is taken using a dental impression material.
This impression serves as a mold for creating the crown. Additionally, the dentist may select a shade that matches the patient's other teeth to ensure that the crown blends in aesthetically. The impression, along with any other necessary details on occlusion (bite) and shading, is then sent to the laboratory where the technician can begin the process of creating a custom crown that fits the patient's mouth perfectly.
