Founded in 1972, Zest Dental Solutions in Carlsbad manufactures the globally patented LOCATOR Attachment System used in implant-retained overdenture restorations. The LOCATOR platform integrates with more than 100 implant manufacturer systems, supporting clinical workflows at implant-focused practices including Packard Dental across North County. Zest operates its global headquarters and primary R&D facility on Loker Avenue East near Poinsettia Park, with satellite production in Anaheim and Escondido. The company's portfolio extends beyond attachments to include Danville Materials chairside composites and the ENCOMPASS digitally powered overdenture treatment system. BC Partners acquired the company to expand distribution that now reaches restorative practices including La Costa Dental Excellence across the La Costa corridor. The LOCATOR FIXED system's dual-retention abutment design accommodates up to 15 degrees of angular correction per implant, enabling full-arch rehabilitation on as few as four fixtures.
