United States v. Dentsply Int'l, Inc., was a 2005 Third Circuit antitrust decision in the United States finding that Dentsply, a monopolist manufacturer-supplier of dental supplies, used its exclusive dealing policy to keep rival firms' sales "below the critical level necessary for any rival to pose a real threat to Dentsply's market share,". This was in violation of Sherman Act § 2. The court so held despite the lack of long term contracts between the manufacturer and its dealers.
