Description

Dental Amalgam CAS NO 8049-85-2 is a durable, high-strength restorative material used for direct fillings in posterior teeth. Its primary value lies in its exceptional longevity, cost-effectiveness, and ease of manipulation, making it a cornerstone material in restorative dentistry for decades. This alloy is essential for dental clinics, hospitals, and dental material manufacturers globally who require a reliable and proven solution for long-term tooth restoration. Its performance is defined by a precise composition of silver, tin, copper, and other metals, which react with mercury to form a hard, stable compound.

Application

• Posterior Dental Restorations: Primary material for Class I and Class II cavity fillings in molars and premolars due to its wear resistance and strength under chewing forces.
• Core Buildups: Used as a foundation material for building up tooth structure prior to crown placement.
• Pediatric Dentistry: Employed in fillings for children's primary teeth where durability and speed of placement are critical.
• Long-Term Temporary Restorations: Suitable for situations requiring a robust, long-lasting temporary filling.
• Dental Education and Training: A standard material used in dental schools for teaching restorative techniques.
• High-Stress Bearing Areas: Ideal for restoring teeth in patients with heavy occlusal forces or bruxism.

Quality Control

Our Dental Amalgam is manufactured and tested to meet or exceed international standards, including ISO 24234:2015 for dental mercury and ISO 1559 for dental amalgam alloy. Each batch undergoes rigorous quality testing to ensure compliance with industry standards for composition, particle size, setting time, compressive strength, and creep. Certificates of Analysis (COA) detailing these parameters are available upon request to ensure traceability and quality assurance for dental professionals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat and incompatible materials. Ensure containers are properly sealed to prevent contamination and exposure to air.
