Overview
Dentsply Sirona is a United States-based dental technology company formed in 2016 through the combination of Dentsply International and Sirona Dental Systems. The merger brought together two businesses with complementary capabilities: Dentsply had long been associated with dental consumables, artificial teeth, restorative materials, endodontic products, preventive care products, and related laboratory supplies, while Sirona was particularly recognized for dental equipment, digital workflows, imaging systems, treatment centers, and computer-aided dentistry. The resulting company markets products in more than 120 countries and operates manufacturing facilities in numerous jurisdictions. The roots of the Dentsply business extend to Dentist's Supply Company, established in New York City in 1889. Its early activities included the manufacture and distribution of artificial teeth and other dental supplies. The company developed expertise in dental ceramics, denture teeth, restorative materials, and equipment, and expanded through acquisitions and international distribution relationships. It adopted the Dentsply name in 1969, reflecting the growing recognition of its product brand. Sirona traces its history to a dental manufacturing business founded in Erlangen, Germany, in 1877. Dentsply's 1993 combination with Gendex Corporation created a larger publicly traded dental-products group and strengthened its position in dental imaging and equipment. Subsequent acquisitions broadened the portfolio, notably the purchase of Astra Tech's dental implant business from AstraZeneca in 2011. In 2016, the merger with Sirona created a broad dental-solutions platform spanning consumables, clinical equipment, digital dentistry, imaging, implants, orthodontics, endodontics, prosthetics, laboratory products, and preventive care. The company serves general dentists as well as specialists in orthodontics, endodontics, implant dentistry, prosthodontics, oral surgery, and dental hygiene. Its portfolio includes treatment centers, imaging systems, CAD/CAM equipment and software, intraoral scanning and milling workflows, dental instruments, anesthetics, restorative materials, adhesives, impression materials, endodontic files and obturation products, implants, artificial teeth, prophylaxis products, and laboratory consumables. Important brands and platforms associated with the group include CEREC, Sirona treatment centers, Cavitron, Astra Tech Implant System, Primescan, Primemill, Orthophos, and other professional dental technologies. Dentsply Sirona has used acquisitions, product development, and digital integration to expand beyond individual consumables or machines toward connected workflows. Its strategic proposition is to help dental practices diagnose, plan, treat, restore, and maintain oral health using equipment and materials that can be integrated across the practice and laboratory. The company also participates in dental education and research initiatives, including sponsorship of the SCADA student research competition with the American Association for Dental Research. Corporate leadership has changed substantially since the merger. Jeffrey Slovin, Bret Wise, and Christopher Clark departed senior roles in 2017; Donald Casey Jr. became chief executive in 2018, was dismissed in 2022, and was temporarily succeeded by John Groetelaars. Simon Campion became chief executive in 2022. In 2025, the company announced that Daniel Scavilla would become president and chief executive officer on August 1, succeeding Campion. The company has also faced regulatory and governance scrutiny, including investigations related to disclosures and allegations involving former senior executives, as well as criticism of its continued business activity in Russia after the 2022 invasion of Ukraine. These matters form part of the company's recent public record but do not alter its status as an active global dental-products manufacturer.
History
Dentsply Sirona combines the histories of Dentsply and Sirona, two long-established dental businesses with different but complementary specializations. Sirona's origins are traced to a dental manufacturing enterprise established in Erlangen, Germany, in 1877. The Dentsply lineage began in New York City in 1889 as Dentist's Supply Company. Its early business included artificial teeth and dental supplies, and it developed manufacturing expertise in dental ceramics, denture teeth, restorative products, and professional equipment. During the first half of the twentieth century, Dentist's Supply Company expanded through distribution relationships, international subsidiaries, and acquisitions. E. de Trey & Sons became an important European marketing and distribution partner in the 1920s. The company also acquired interests in artificial-tooth manufacturing and developed overseas production and research capabilities in response to tariffs and international competition. Acquisitions such as LD Caulk, Ransom and Randolph, and other dental businesses broadened its product range. The company changed its name to Dentsply International in 1969 as the Dentsply product identity became increasingly established. Dentsply's postwar development included products and technologies for prophylaxis, dental materials, artificial teeth, and equipment. The company expanded internationally and built a portfolio serving both dental practices and laboratories. In 1993, Dentsply acquired Gendex Corporation in a reverse transaction, creating a larger public dental-products company and adding capabilities in dental imaging. It subsequently acquired Eureka X-Ray, although that business was later divested. The same period also included the bankruptcy of Healthco, a major U.S. distributor, illustrating the importance and volatility of dental distribution channels. International markets became increasingly important to Dentsply. By the early 2010s, the company generated a majority of sales outside the United States and had built a broad portfolio in restorative dentistry, endodontics, implants, preventive care, laboratory products, and equipment. In 2011, Dentsply purchased Astra Tech's dental implant business from AstraZeneca. The transaction significantly enlarged the company's implant activities and added the Astra Tech Implant System to its strategic portfolio. On February 29, 2016, Dentsply combined with Sirona Dental Systems in a merger described as a merger of equals. The transaction created Dentsply Sirona and united Dentsply's consumables-oriented business with Sirona's equipment and digital-dentistry capabilities. The combined company could offer dental practices a more complete set of products, from diagnostic imaging and treatment centers to CAD/CAM workflows, restorative materials, implants, and laboratory equipment. The years after the merger were marked by leadership changes and continued portfolio development. In 2017, chief executive Jeffrey Slovin, executive chairman Bret Wise, and president Christopher Clark left their senior positions. Donald Casey Jr. became chief executive in 2018 after an interim period under Mark Thierer. Dentsply Sirona later acquired Byte, an orthodontics company, in 2021, extending its presence in direct-to-consumer and digitally enabled orthodontic services. In 2022, the company removed Casey as chief executive and appointed John Groetelaars on an interim basis. Simon Campion, formerly an executive at BD, was subsequently appointed president and chief executive officer. The company and regulators also examined securities-related allegations involving former executives. In 2023, external observers criticized the company's continued business activity in Russia after the invasion of Ukraine. In 2025, Dentsply Sirona announced Daniel Scavilla as the incoming chief executive, effective August 1. The business remains an active international supplier of dental equipment, digital systems, consumables, implants, orthodontic products, and laboratory solutions.
