Gold is one of the precious metals that has been used in dentistry for a long time due to its unique properties. In this article, we will examine the features and various applications of gold in dentistry.
Features of Gold in Dentistry
- Biocompatibility: Gold does not cause any allergic reactions and is compatible with human body tissues. This makes it a safe material for use in dentistry.
- Durability and Stability: Gold is highly resistant to corrosion and wear, giving it a long lifespan. This feature is especially important in dental fillings and crowns.
- Malleability and Formability: Gold can be easily shaped and molded, allowing dentists to create precise restorations. This feature is particularly useful for detailed dental repairs.
Applications of Gold in Dentistry
- Dental Fillings:
- Gold is used as a material for filling decayed and damaged teeth. These fillings are highly durable and resistant to breaking or wearing out.
- Gold fillings also help prevent dental sensitivities due to their compatibility with mouth tissues.
- Dental Crowns:
- Gold is the main material used in the fabrication of dental crowns and bridges. Gold crowns are ideal for dental restorations due to their high resistance and compatibility with oral tissues.
- These crowns are especially useful for back teeth, which endure greater chewing pressure.
- Dental Posts (Pins and Posts):
- Gold is used as a material for making dental posts and pins, which help reinforce and stabilize teeth. These posts and pins are commonly used in restorative and reconstructive dental procedures.
- Orthodontics:
- In the past, gold was used to make braces and orthodontic wires. Today, although newer and cheaper materials like stainless steel have replaced gold, it is still used in certain cases due to its flexibility and resistance to corrosion.
Advantages of Using Gold in Dentistry
- Chemical Inertness: Gold is a stable and safe material for use in the mouth because it does not react with oral fluids.
- Aesthetic Appeal: Although the yellow color of gold may not always be desirable, in many cases, its beautiful and luxurious appearance is considered an advantage.
- Long Lifespan: Gold restorations have a significantly longer lifespan compared to other materials like composites and amalgams.
Conclusion
Due to its unique properties, gold continues to be one of the main materials used in dentistry. Its biocompatibility, durability, and high formability make it an ideal choice for various dental restorations and applications. Despite its high cost, the numerous advantages of gold ensure it maintains a special place in modern dentistry.
