Device Story

Porta Maximum is an extra-hard, gold-based dental alloy (83% noble metal content) used by dental technicians to fabricate dental restorations. It serves as a substrate for inlays, onlays, crowns, bridges, and removable partials. The alloy is copper-free, facilitating telescopic and milling applications. Technicians veneer the alloy with low-fusing dental ceramics or composites to achieve aesthetic results. The device provides a durable, corrosion-resistant, and biocompatible foundation for dental appliances, benefiting patients by restoring dental function and aesthetics.

Clinical Evidence

Bench testing only. The device complies with international standard ISO 9693 for dental alloys and meets essential requirements of the European directive 93/42/ECC.

Technological Characteristics

Extra-hard gold-based dental alloy; 83% noble metal content; copper-free. Complies with ISO 9693. Suitable for veneering with low-fusing dental ceramics and composites.

Indications for Use

Indicated for patients requiring dental restorations including inlays, onlays, partial crowns, crowns, short and long span bridges, and removable partials. Suitable for telescopic and milling work.

Regulatory Classification

Identification
