Which type of ceramic is the most commonly used in dentistry?

  1. Glass-ceramic

  2. Composite

  3. Porcelain

  4. Alumina

The correct answer is: Porcelain

Porcelain is the most commonly used ceramic in dentistry due to its excellent properties that align with the requirements of dental restorations. It has a favorable appearance, mimicking the natural translucency and color of teeth, which makes it ideal for aesthetic dental work such as crowns, veneers, and bridges. Porcelain also provides good wear resistance and can withstand the forces that occur during chewing, making it durable for long-term use in the oral cavity. Moreover, porcelain can be easily shaped and polished to achieve a smooth surface, enhancing both its aesthetic appeal and functionality. Its biocompatibility is another significant advantage, allowing it to be used safely in the mouth without causing adverse reactions. These characteristics have made porcelain a go-to material for dental professionals when creating restorations that require a balance of beauty and strength in a patient's smile.
