Dentistry moves to 3D Printing Author: Avi Cohen, Solutions Marketing Manager, Objet Geometries Ltd Custom rapid manufacturing of implants, supporting structures and other dental solutions is just around corner. The days when dentists have to ladle quantities of goo into patients' mouths to take impressions are over. As the 3-D-printing bullet train continues to accelerate so does the pace of change in dentistry. The day when everything from scheduling to final restoration is handled digitally, has arrived. Today, a two-minute digital scan of a patient's teeth captures the patient’s entire dentition in real time. The 3-D digital file is then delivered to a dental lab where milling or 3-D printers craft a solid artificial model of the dentition from zirconium dioxide (instead of the traditional materials of choice, gold and platinum). New and exciting technologies are empowering dentists to provide more rapid, accurate, non-invasive, and automated dental solutions. Intra-oral scanners and their designated imaging software continue to improve. Scan speed, image capture, and enhancement capabilities are developing at a record pace, enabling Cone Beam CT scanners to provide astounding diagnostic and treatment possibilities. This year has seen a dramatic increase in chair-side and laboratory devices dedicated to digital imaging and impressioning, and CAD/CAM fabrication of restorations. Data capture systems has expanded the scope of digital dentistry for practices and laboratories alike. As a result of intense R&D efforts, manufacturers have created 3-D scanning systems engineered to capture data from the “negative” spaces inside tray impressions, both in the laboratory and in the clinic. From a precise, detailed 3-D image of the impression, CAD software converts the “negative” form into a “positive” 3-D representation of the missing teeth. Working from this virtual model, the clinician can manipulate a number of different components. This approach is seen as a transitional step for laboratories that see the benefits offered by digital dentistry but that need to accommodate client-dentists who prefer traditional tray impressions. For many dental professionals, the digital evolution has been a long-awaited and welcomed transition that paves the way for more rapid, labor-saving CAD/CAM automation, which improves quality and precision and lowers costs. The open question is when dentists will embrace these innovative technologies and use them to advance their practices forward? With the roll-out of new systems and materials over the coming year, increasing current capabilities even more, many believe that more dentists will see the technology as a viable alternative to their current dental techniques. For dentists who are ready, willing, and able to integrate digital impression technology, systems are available today that move the digital process back to the oral preparation site. By scanning the prepared tooth and creating a digital impression, the accuracy of the data capture is enhanced and the digital restorative process begins sooner. For most labs that work with these progressive dentists all that is required is an investment in design software (and appropriate training). The crafting of the dental products is outsourced to production facilities where 3-D printing technology rapidly prints accurate 3-D models, to the dentist specifications. In many respects, digital dentistry is already here, and a growing number of laboratory owners have incorporated digital dentistry in some form into their strategic business models. Some day in the near future, we may look back at 2009 as the year when the dental-lab industry passed the point-of-no-return in the transition from the traditional manual workflow to an all-digital process.
