14 exhibitors Chicago Midwinter — February 22, 2019 Primescan perfects digital impressions By Dentsply Sirona Staff n Easier than ever, faster than before, more accurate than previ- ously possible — all describe Primes- can, the new intraoral scanner from Dentsply Sirona. With its completely new, patent- pending digital-impression tech- nology, Primescan enables high- precision digital impressions to be taken of the entire jaw. These scans pre- sent numerous possibilities for users. Primescan was designed for vari- ous digital workflows — with the laboratory directly in the practice, with CEREC or in cooperation with external partners. Validated inter- faces noticeably simplify the process, offering dentists the flexibility they desire, according to the company. What was considered an absolute sensation more than 30 years ago is almost taken for granted today. In terms of quality, digital intraoral impressions are technically equal to, and in some cases superior to, traditional impressions, while also offering an improved patient experi- ence. Dentsply Sirona introduced the digital impression to dentistry with CEREC. Now, with Primescan, Dentsply Sirona is introducing an intraoral scanner with outstanding technol- ogy, which enables scans that are more precise than anything we have known before, the company asserts. This has been substantiated by a new study at the University of Zurich1. “Dentists rightly expect products and solutions from Dentsply Sirona that make their work at the dental practice easier, safer and better,” said Dr. Alexander Völcker, group vice president, CAD/CAM and orthodon- tics at Dentsply Sirona. “Primescan is the solution to an important issue in practices — the option of faster, precise impressioning — which is model calculation, is complete in just two to three minutes. With Primescan, users can lev- erage the full potential of digital processes for better treatment. The modular concept offers a suitable solution for every need within the practice. The digital 3-D model can be transmitted to a laboratory via the new Connect software (formerly Sirona Connect) and can also be further processed with different soft- ware, e.g., for orthodontic or implant treatment planning. The newly developed Connect Case Center Inbox enables laborato- ries around the world to connect to the Connect Case Center. This allows a validated scan data from Primes- can to be received easily for further processing in the desired programs and workflows. Alternatively, the res- toration can be planned and manu- factured in the practice using the new CEREC software 5, with its new design, intuitive touch functionality and noticeably improved screen reso- lution, according to Dentsply Sirona. Dr. Alexander Völcker expresses his confidence in the technology: “Digital impressions with Primes- can are the starting point for other exciting digital processes, without limiting the future decisions of dental practices. With our seamless solu- tions and validated workflows with external partners, we are setting new standards which, thanks to digi- tal technologies, enable even better dentistry.” Reference 1.

The scan of the surfaces of the teeth is completed with high-resolu- tion sensors and shortwave light, cap- turing up to one million 3-D points per second. With optical high-frequency contrast analysis, they can now be calculated more accurately than ever before, according to the company. Dentsply Sirona has submitted a patent application for this process. With Primescan, it also is possible to scan deeper areas (up to 20 mm). This enables digital impressions even for subgingival or particularly deep preparations. Virtually all the tooth surfaces are captured, even when scanning from very acute angles. Pri- mescan captures the dental surfaces immediately, in the required resolu- tion and with a high degree of clarity even at great depths, thereby ensur- ing a much more detailed 3-D model. The precise scanning technol- ogy enables Primescan to be imple- mented universally. Not only does it produce high-precision images of natural teeth and preparations, it also provides extremely accurate images of other materials commonly used in dentistry, according to Dentsply Sirona. For example, implant specialists appreciate the simple impressions of edentulous arches or sites with implants, and orthodontists highly rate the detailed scan results for soft tissues (gums, frenulum). With this new scanning technology, impres- sions can be completed very quickly.

Mouth- guards formed this way offer superior protection, and all appliances bring the comfort of a fit customized for the individual patient. While the manufacturing of such appliances is usually done in a lab, Keystone Industries is happy to bring the process to your office with the Pro- Vac vacuum former. The Pro-Vac offers the same con- Here in Chicago To learn more about Keystone Indus- tries products, visit No. 4011 venience and power of the Machine III at a fraction of the cost. Bringing the Pro-Vac into your office can increase patient services, accelerate appliance delivery times and save lab fees, according to Keystone. Improving on the design of the Machine III, the base of the Pro-Vac vacuum former is made of a strong, lightweight thermoplastic designed for high temperatures. This housing dampens vibrations better than traditional housing, result- ing in a quieter unit. In addition, the thermoplastic casing brings the cost of the Pro-Vac down almost 20 percent from the cost of the Machine III, while maintaining the same superior oper- ating level, the company asserts. The Pro-Vac and Machine III are both more powerful than any other dental vacuum former, according to Keystone, and produce more accu- rate and defined thermoplastics than any other model. Its heating element design and placement ensures even heat distribution throughout the ther- moplastic material. This makes the Pro-Vac ideal for producing bleaching trays, sports mouthguards, implant splints, custom impression trays, den- ture bases, copings, and temporary crowns, bridges, splints and orthodon- tic devices. For superior performance, reliabil- ity and price, add the Pro-Vac vacuum former to your office, Keystone Indus- tries recommends.
