Question

A gingival retraction cord is placed ____after the crown preparation is completed; it is removed just before______ the final impression is taken.

Answer 1

A gingival retraction cord is placed after the crown preparation is completed; it is removed just before the final impression is taken. Gingival retraction cord is a dental material used to temporarily move the gums away from the tooth structure for crown preparation.

Step-by-step explanation:

A gingival retraction cord is placed after the crown preparation is completed; it is removed just before the final impression is taken.

Gingival retraction cord is a dental material used to temporarily move the gums away from the tooth structure. It acts as a barrier, allowing the dentist to access deeper parts of the tooth for crown preparation.

By placing the retraction cord after the crown preparation, the dentist creates space for a more accurate impression of the tooth. The cord is then carefully removed before taking the final impression to ensure that the gums return to their normal position.

Answer 2

A gingival retraction cord is placed after the crown preparation is completed; it is removed just before the final impression is taken.

Step-by-step explanation:

A gingival retraction cord is placed after the crown preparation is completed; it is removed just before the final impression is taken.

In dentistry, a gingival retraction cord is used to push the gingival tissue away or retract it from the tooth structure. Once the crown preparation is completed, the retraction cord is inserted into the sulcus, which is the space between the tooth and the gingival tissue.

This helps to expose the tooth structure and create space for a more accurate final impression. The cord is typically removed right before taking the final impression to ensure that the impression material captures the exact contours of the tooth without any interference.
