Less than two months after changing hands, Santa Maria-based DenMat Holdings has acquired some of the assets of its new CEO’s old company.

DenMat, a major employer with several hundred workers at its Skyway Drive facility, said on Jan. 6 that it has acquired a portfolio of dentistry products from Discus Dental. Steve Semmelmayer was CEO of that firm from 2008 until early 2011.

Late last year, Semmelmayer joined in with Centre Partners, a private equity firm, and Mill Street Partners, to buy DenMat. That acquisition came four years after DenMat was purchased by DLJ Merchant Banking Partners, the private equity arm of megabank Credit Suisse.

The new portfolio includes a line of impression materials – the stuff patients bite down on to provide impressions for making crowns and other products – and a line of bonding agents. They will join DenMat’s flagship line of Lumineers, a kind of high-end tooth veneer about the thickness of a contact lens that can be applied without grinding down patients’ teeth.

“Over the past three decades, DenMat built some of the most successful and recognized brands in dentistry,” Semmelmayer said in a news release. “Leveraging this brand equity with expanded product offerings that give dental professionals a wider range of effective treatment solutions is our goal. The acquisition of the Discus Dental restoratives and impressions brands is an important step forward in developing a vibrant, new DenMat.”
