Full Gold

Full gold crowns from Nakanishi Dental Laboratory are expertly fabricated from high-quality dental alloys. Our technicians carefully craft each 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.
