Final answer:
The second appointment for the placement of a cast restoration typically involves placing the restoration. Impressions and tooth preparations are generally done during the first appointment, and the cast is made in a lab before the second visit.
Step-by-step explanation:
The procedure that takes place during the second appointment for the placement of a cast restoration is placing the restoration. During the first appointment, the tooth is prepared for the restoration and an impression is made to create a model for the cast.
The model is then sent off to a lab where the restoration is fabricated. At the second appointment, the restoration is fitted, adjusted, and cemented into place. Administration of anesthesia may also be necessary if there is a need for any minor adjustments to the tooth structure or if the patient requires it for comfort.
