ZEST Anchors has been a global leader in the manufacturing of overdenture attachments. The original ZEST Anchor Attachment was developed in 1972 by Max Zuest at his dental laboratory in San Diego, California. Forty years later, our departed founder Max is remembered for his vision as a pioneer in dentistry.Zest pioneered self-aligning attachments to combat the damage done by the improper seating of overdentures. We have since achieved certification to the stringent requirements of ISO 9001 for the design and quality manufacturing of dental attachments. The LOCATOR product line is our third generation of attachments and has achieved worldwide acceptance as the premier overdenture attachment in the dental industry.
