When it comes to dental restorations, the materials used must meet strict standards to ensure both functionality and safety for the patient. One such important component in the creation and restoration of dental appliances is the brazing material, a filler metal that joins two metal components through a process known as brazing. The International Organization for Standardization (ISO) has provided guidelines for the use of brazing materials in dentistry through ISO 9333:2022 and has been adopted by the Bureau of Indian Standards (BIS) in India as IS 18803:2024. This standard sets requirements for chemical composition, mechanical properties, corrosion resistance and more for brazing materials used in dentistry, providing clear guidelines for manufacturers and healthcare professionals.

What is IS 18803: 2024 Dentistry for Brazing Materials?

The Indian Standard IS 18803: 2024 which is alike to ISO 9333: 2022 ‘Dental Medicine - Brazing Materials’ issued by the International Organization for Standardization (ISO), which was adopted by the Bureau of Indian Standards (BIS) on the recommendation of the Dentistry Sectional Committee and after approval of the Medical Equipment and Hospital Planning Division Council. It sets guidelines for chemical composition, mechanical properties, biocompatibility, corrosion resistance, and melting point. These materials are crucial for the fabrication of durable and reliable dental restorations.

These materials are crucial for the fabrication of durable and reliable dental restorations. Standards emphasize safety and environmental considerations, including limits for hazardous elements such as cadmium, beryllium, lead, and nickel. By following these requirements, manufacturers can produce high-quality brazing materials that ensure the longevity of dental instruments and prevent adverse reactions in patients.

Significance of IS 18803: 2024 

The IS 18803:2024 standard is very important as it establishes guidelines for the safe and effective use of brazing materials in the dental industry. Brazing is an essential technique for joining dental alloys in the production of dental appliances and restorations. This process ensures the durability and strength of dental products, preventing them from failing prematurely due to weak bonding or poor material performance. By including this standard, dental professionals and manufacturers can be confident that brazing materials used in dental procedures meet rigorous global standards for both safety and effectiveness.

IS 18803:2024 helps ensure biocompatibility of materials used in the dental sector. Biocompatibility is very important because dental materials should not cause adverse reactions when in contact with oral tissues. This standard establishes specific limits for hazardous elements such as nickel, cadmium, beryllium, and lead, protecting patients from potential health risks. Aligned with international standards such as ISO 9333:2022, IS 18803:2024 ensures that dental bracing materials not only perform optimally but also maintain the highest standards of health and safety, promoting patient confidence and satisfaction.

Key Components of IS 18803:2024

IS 18803:2024 is structured to cover many aspects of brazing materials, including their composition, test methods and performance criteria. Here are some key components:

• Chemical composition: The chemical composition of brazing materials is critical to ensuring their effectiveness and safety. The standard states that all elements present in brazing materials must be declared, especially those present in concentrations greater than 1%. If the concentration of a particular element is between 0.1% and 1%, the name or symbol of the element must be given. The standard also sets limits for hazardous elements such as cadmium, beryllium, and lead, ensuring that brazing materials are safe for human consumption.
• Biocompatibility: Although specific quantitative requirements for freedom from biological hazards are not included in the standard, IS 18803:2024 recommends reference to ISO 10993-1 and ISO 7405 when evaluating the potential biological hazards of brazing materials. This ensures that when the material is used in dental procedures that involve close contact with oral tissues.
• Mechanical properties: The standard requires that brazed joints have a tensile strength that meets specific criteria based on the strength of the material being joined. For materials with 0.2% proof strength exceeding 250 MPa, the tensile strength of the brazed joint shall also exceed 250 MPa. This make sure that the brazing material provides a strong and durable bond between the metal parts used in the dental restoration.
• Corrosion resistance: Corrosion resistance is another important property for brazing materials in the dental industry. The standard specifies that the release of metal ions from a brazed joint should not exceed 200 µg/cm² over a 7-day immersion period. This ensures that the material remains stable and does not leach harmful substances into the oral cavity over time.
• Melting point: The melting point of the brazing material is an important consideration for its performance during the brazing process. The temperature of solids and liquids should fall within the range of values specified by the manufacturer's instructions, ensuring consistent performance during the dental procedure.

Scope of IS 18803:2024

The scope of IS 18803:2024 extends to all brazing materials used for joining metal parts in dental restorations and appliances. However, it clearly excludes brazing materials with silver as the main ingredient. The standard is designed for use by manufacturers, dental laboratories and professionals who need to ensure that the materials they are using meet the necessary regulatory and quality requirements. The main purpose of the standard is to ensure the quality, safety and effectiveness of brazing materials, which makes it important for those involved in dental restoration work.

Benefits of IS 18803:2024

Adopting IS 18803:2024 offers several benefits to manufacturers, dentists and patients:

• Improved safety and biocompatibility: One of the most important benefits of following IS 18803:2024 is the increased safety of dental procedures. By setting limits on hazardous elements such as nickel, cadmium, and lead, the standard helps protect patients from the risks associated with the leaching of harmful substances.
