What is a key difference between porcelain and metal inlays?

Cementation is a critical factor that differentiates porcelain and metal inlays, primarily due to the materials' distinct properties and interactions with dental adhesives. When it comes to porcelain inlays, they require specific types of resin cements that can bond effectively to the ceramic material, often involving additional surface treatments to enhance adhesion. This process can be more complex than that for metal inlays, which may be configured to utilize a simpler cementation process, typically employing traditional dental cements. The choice of cement can affect the clinical outcomes regarding retention and durability of the inlay.

Additionally, the method of cementation influences aspects such as the aesthetic outcomes and bonding strength, making it a pivotal consideration in restorative dentistry. Understanding the nuances of cementation helps clinicians choose appropriate materials based on the situation, patient needs, and desired outcomes, thereby showcasing the importance of this difference in clinical practice.
