But wait, you might be wondering about PMMA vs zirconia. You are not alone. This read will explain the main differences between these two approaches to find out the best-suited option for you. Stay here and keep reading to get informed!
PMMA(Polymethyl Methacrylate)
PMMA (Polymethyl Methacrylate) refers to a lightweight acrylic material that is well known for its use in temporary dental restorations. PMMA is famous for its affordability, aesthetic sense, and easy fabrication. Although it is a cheap and comfortable option for smile restoration, PMMA is less durable and more prone to wear compared to other materials like Zircona.
Zircona(Zirconium Dioxide)
Zirconia (Zirconium Dioxide) is a widely used ceramic material well-known for its durability, biocompatibility, and extraordinary strength. It is mostly utilized in modern restorative dentistry for permanent bridges, Dental Implants and crowns. Zirconia is metal-free and non-toxic, reducing the chances of gum irritation or any allergic reaction.
