Full cast gold crowns from Nakanishi Dental Laboratory are expertly fabricated from high-quality dental alloys. Our technicians carefully craft each full cast crown and bridge to exhibit exceptional contours and exquisite attention to detail. Thanks to their clinical success, biocompatibility, and ease of use, these restorations have withstood the test of time and remain a popular choice. They are durable but remain gentle on opposing dentition, which makes these an excellent option for bruxers.
Through the use of CAD/CAM technology, our technicians can fabricate these industry staples with superior fit and finish than before. We utilize the traditional "lost wax" casting method to fabricate these durable and high-quality restorations.
Digital Full Gold Crowns
Noble and high noble gold restorations enter the digital age with milled gold. Milled full gold crowns eliminate the "lost wax" casting method traditionally used to fabricate gold crowns. Models are scanned and milled directly from our technicians digital design from a solid gold disc. This process eliminates any possibility of porosity and results in high quality, stunning restorations with minimal chairside finishing or polishing.
Full-cast gold crowns are indicated for crowns, veneers, inlays, onlays, and bridges.
Full-cast gold crowns are contraindicated for partials and implants.
Inlays and onlays can also be fabricated as a full-cast restoration. Feather-edge margin preparations are indicated for full-cast restorations, but any margin preparation may be used.
