What is the best restorative treatment for a large class II restoration?

• A. Composite filling
• B. Amalgam filling
• C. Gold onlay
• D. Resin onlay

Answer: (C)

For a large class II restoration, the use of a gold onlay is often considered the best restorative treatment due to several key factors that make it particularly suitable for this type of restoration. Gold onlays provide excellent strength and durability, which is essential for large restorations that need to withstand significant biting forces. The mechanical properties of gold, such as its high resistance to wear and fracture, help ensure that the restoration will last a long time, making it an ideal choice for areas of the mouth that are subject to heavy chewing pressure. Additionally, gold can be precisely fabricated to fit the specific contours of the tooth, allowing for optimal adaptation to the prepared tooth structure. This fit helps to prevent future caries and provides a good seal at the margins, which is crucial for long-term success. Another benefit of gold onlays is their biocompatibility, which minimizes the risk of allergic reactions. The aesthetic aspects may not be as favorable as some other materials; however, in many cases, the functional advantages of gold onlays outweigh issues regarding appearance, especially in posterior teeth where aesthetics are less critical. Other treatment options, such as composite and amalgam fillings, while they can also be effective, may not offer the same level of durability or be as suitable
