The owner of Cadent Inc., which provides digital imaging services and equipment for dentists and orthodontists, says it will shut its Carlstadt plant, lay off 119 people and move the work to Costa Rica and Mexico. The closing is part of a consolidation as a result of the company’s acquisition by San Jose, Calif.-based Align Technology Inc. in May, a company statement said. Align is one of several U.S. medical device companies to choose Costa Rica as a location for manufacturing.
