How does the bevel edge assist in tooth preparation?

1. It provides a sharper edge for extractions

2. It allows for better seating and holding of a crown

3. It decreases the chance of infection

4. It helps align orthodontic appliances

The correct answer is: It allows for better seating and holding of a crown

The bevel edge is a crucial feature in tooth preparation because it improves the seating and retention of a crown. When a tooth is prepared for a crown, the bevel allows for a smooth transition between the prepared tooth structure and the crown itself. This angled edge increases the surface area for the crown to adapt closely to the tooth, enhancing the fit and stability of the restoration. A well-seated crown is essential for preventing any movement that could lead to marginal discrepancies, which can, in turn, affect susceptibility to decay and further dental issues. The bevel enhances the overall effectiveness of the dental restoration by ensuring a tighter and more secure fit, promoting long-term success in crown placement.
