Questions
AI-generated answers, 19 Sep 2026
What types of dental restorations is the Howmedica A-35 Dental Alloy specifically designed for, and how is it used in the dental laboratory?
The Howmedica A-35 Dental Alloy is designed exclusively for dental laboratories to fabricate cast or porcelain-fused-to-metal crowns and bridges. It is supplied in a form suitable for dental casting procedures, meaning it is melted and poured into molds to create precise restorations. The alloy’s noble metal composition—including gold, palladium, platinum, or silver—ensures durability and biocompatibility for long-term use in patients.
Is the Howmedica A-35 Dental Alloy intended for reuse, or is it meant to be used only once in a dental laboratory?
The Howmedica A-35 Dental Alloy is explicitly intended for single-use in dental laboratories. Since it is supplied for casting procedures, each batch is meant to be consumed during one fabrication cycle. Reuse is not recommended, as it could compromise the alloy’s integrity, sterility, or performance for patient restorations.
What storage conditions should be followed to maintain the alloy’s integrity before use in dental casting?
While the data does not specify exact storage conditions, the alloy’s single-use nature and sensitivity to handling imply it should be stored in a dry, sealed environment to prevent contamination or degradation. Proper storage ensures the alloy remains suitable for casting without oxidation or corrosion, which could affect the final restoration’s quality.
How was the FDA clearance for this alloy determined, and what does the product code EJS indicate about its regulatory classification?
The Howmedica A-35 Dental Alloy received FDA 510(k) clearance under the product code EJS, which falls under Class II special controls for dental devices. The clearance was granted as *Substantially Equivalent* (SESE) to a predicate device, meaning it was deemed comparable in safety and effectiveness to an already-approved dental alloy. The Dental (DE) advisory committee reviewed it, confirming its suitability for cast or porcelain-fused-to-metal restorations.
