What are base metals commonly used for in dental prostheses?

1. Heat resistance

2. Strength and durability

3. Ornamental purposes

4. Lightweight and flexibility

The correct answer is: Strength and durability

Base metals are commonly used in dental prostheses primarily for their strength and durability. These metals, such as nickel, chromium, and cobalt, are favored in dentistry because they provide the necessary structural integrity required for dental restorations, such as crowns, bridges, and dentures. Their strength allows them to withstand the forces of chewing and the wear and tear that occur in the oral environment, making them suitable for long-lasting restorations. Furthermore, base metals have excellent corrosion resistance properties, which is crucial for maintaining the integrity of a dental prosthetic in the moist and chemically diverse environment of the mouth. The durability of these metals ensures that dental restorations can endure significant functional use without breaking or failing. In contrast, while lightweight and flexibility, heat resistance, and ornamental purposes may be relevant considerations for certain materials in dentistry, they do not capture the primary reasons why base metals are utilized in prostheses. The focus is primarily on achieving robust and lasting functional results in dental applications.
