These materials are known for their exceptional strength, making them suitable for both anterior and posterior restorations. Lithium disilicate offers a natural appearance, whereas zirconia is renowned for its toughness and wear resistance.
• Multilayered Zirconia: Traditional zirconia materials used in dental restorations were often opaque, which could compromise the esthetic outcomes. However, recent advancements have led to the development of multilayered zirconia that incorporates different shades and translucencies, mimicking natural tooth enamel. This has expanded zirconia’s use in more aesthetic applications, such as anterior crowns.
• Nanotechnology in Ceramics: The introduction of nanotechnology into ceramic materials has further enhanced their properties. For example, nanoceramics, which are created by incorporating nanoscale particles, offer improved strength, wear resistance, and translucency. This makes them suitable for both functional and esthetic restorations.

2. Polymers and Hybrid Materials

Polymers are another category of materials that have seen significant innovation in recent years. Although not as strong as ceramics, polymers offer advantages in terms of flexibility, ease of handling, and cost-effectiveness.

• Resilon® and PMMA: These are examples of polymer-based materials commonly used for temporary restorations or partial dentures. They are lightweight and offer good esthetic results but were previously limited by their lack of long-term durability. However, advances in polymer chemistry have led to the development of stronger, more durable polymers that can be used for permanent restorations in some cases.
