Dental amalgam is a material used in restorative dentistry for filling cavities caused by tooth decay. It is a reliable and durable alloy composed primarily of mercury, silver, tin, and copper. For over a century, dental amalgam has been a cornerstone in dental practices worldwide due to its strength, longevity, and cost-effectiveness.
Use in Dentistry:
- Durability and Strength: Dental amalgam is renowned for its exceptional durability and strength, making it an ideal choice for restoring molars and premolars that endure significant chewing forces. Amalgam fillings can last for many years, often decades, with proper oral hygiene and care.
- Affordability: Compared to other restorative materials like composite resins, gold, and ceramics, dental amalgam is more affordable, making it a practical option for patients seeking effective and economical dental care.
- Ease of Use: Amalgam is relatively easy to work with for dental professionals. It remains pliable for sufficient time, allowing for precise placement and contouring. Once placed, it hardens quickly, providing an efficient and effective restoration.
Types of Dental Amalgam:
- High-Copper Amalgam: High-copper amalgam offers superior physical properties, such as enhanced strength and reduced corrosion. It is composed of:
- Mercury (Hg): 50% by weight
- Silver (Ag): 22-32%
- Tin (Sn): 14%
- Copper (Cu): 8%
- Other metals (e.g., Zinc): 1-2%
- Low-Copper (Traditional) Amalgam: Traditional amalgam, despite newer alternatives, remains a reliable and widely used material. Its composition typically includes:
- Mercury (Hg): 50% by weight
- Silver (Ag): 22-30%
- Tin (Sn): 14%
- Copper (Cu): 6%
- Other metals (e.g., Zinc): 1-2%
How to Use and Handle Dental Amalgam
Preparation and Placement:
- Preparation: The cavity is cleaned and shaped to receive the amalgam filling.
- Mixing: The amalgam alloy powder and mercury are mixed to form a pliable mass.
- Placement: The mixed amalgam is placed into the cavity and carefully condensed to remove any voids.
- Shaping and Carving: The amalgam is shaped and carved to restore the tooth's natural anatomy.
- Hardening: Amalgam hardens quickly, providing a durable restoration.
Handling and Disposal: Proper handling and disposal of amalgam are crucial to minimize environmental impact. Dental practices should use amalgam separators to capture amalgam particles, preventing them from entering wastewater systems.
