What is the primary reason to optimize taper during tooth preparation?

• A. Better esthetics
• B. Increased retention
• C. Decreased food impaction
• D. Minimizing tooth structure loss

Answer: (B)

The primary reason to optimize taper during tooth preparation is to increase retention. In restorative dentistry, taper refers to the angulation of the preparation walls. When the taper is optimized, it helps to create a more favorable geometry for the dental restoration, allowing it to resist dislodgment forces.

A well-designed taper enhances the surface area for adhesion and mechanical retention, particularly in crowns, bridges, and other indirect restorations. This increased retention is crucial for the longevity and stability of the restoration in the oral environment, where various forces from chewing and other activities exert pressure on dental work.

Other factors such as esthetics, food impaction, and preserving tooth structure certainly play roles in tooth preparation, but they do not serve the primary purpose of ensuring that the restoration remains securely in place. Retention is paramount for the functionality and effectiveness of the dental restoration, making it essential to focus on this aspect during the preparation process.
