High Growth Space - Digital Dentistry Market Making Forces Chair time savings Variability reduction Selling efficiency improvement "Incalculable value; huge!" - - Joe Carrick, D.D.S, Past President, American Association of Cosmetic Dentists 2006 Annual Report Looking ahead, our recent acquisition of Brontes technologies and its 3-D imaging technology will give patients and dentists another reason to smile. This system will use intraoral scanning technology to rapidly capture precise, 3-D digital dental impressions directly from patient's mouth. As their profession grows more competitive, dentists are seeking patient-friendly ways to improve care, increase productivity and distinguish their practice. 3M's transformations in digital dentistry fit that model perfectly.
