Intended Use
Dental casting alloy used in combination with dental ceramics for fabrication of metallo-ceramic restoration.
Device Story
Palceram 56 is a palladium-silver based dental casting alloy. It is used by dental technicians in a laboratory setting to fabricate metallo-ceramic restorations. The alloy is cast to form the metal substructure, which is then veneered with dental ceramics. The device provides the structural framework for dental prosthetics, benefiting patients by restoring dental function and aesthetics. It is a prescription-only device.
Clinical Evidence
Bench testing only. Physical and mechanical properties (melting point, hardness, yield strength, elongation, CTE, density) were compared to the predicate device using ANSI/ADA 5 and ISO 9693 test methods.
Technological Characteristics
Palladium-silver based dental casting alloy. Composition: 32% Ag, 56.5% Pd, 3.9% Sn, 7.3% In, 0.3% Ru. Physical properties: Melting range 1200-1230°C, Vickers hardness 200-265, CTE 14.9 x 10^-6/°C, Density 11.1 g/cm3. Tested per ANSI/ADA 5 and ISO 9693.
Indications for Use
Indicated for patients requiring metallo-ceramic dental restorations.
Regulatory Classification
Identification
A noble metal alloy is a device composed primarily of noble metals, such as gold, palladium, platinum, or silver, that is intended for use in the fabrication of cast or porcelain-fused-to-metal crown and bridge restorations.
Special Controls
*Classification.* Class II (special controls). The special control for these devices is FDA's “Class II Special Controls Guidance Document: Dental Noble Metal Alloys.” The devices are exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 872.9. See § 872.1(e) for availability of guidance information.
