Primescan, the latest generation of intraoral scanners, is designed for different digital workflows – in practice with CEREC as well as with the dental laboratory or other partners. Using the Connect software, a digital 3D model can be transferred directly to the laboratory of choice for further processing. Using high-resolution sensors and a short-wave light, a scan of the tooth surfaces is accurately captured. Up to one million 3D pixels per second are captured by Primescan, and these can be executed more reliable than ever using optical high-frequency contrast analysis.
New studies confirm high performance of Primescan
Primescan enables highly precise digital impressions to be taken over the entire jaw, as evidenced by a 2019 University of Zurich study.1 Recently, Primescan’s accuracy has been further demonstrated once again by national and international studies.3-5
The study of Dutton et al. demonstrates the versatility of the acquisition technology of Primescan, as it not only records natural and prepared tooth surfaces with high precision, but also captures materials used in dentistry with a high degree of accuracy across all substrates and for complete arch scanning.3 They further tested the effect of different substrates on the trueness and precision of eight different intraoral scanners. In 11 out of 15 categories, Primescan ranked number one, and for the remaining four categories, Primescan ranked among the top three.3
Primescan’s impressive degree of precision in taking digital impression over the entire jaw1 continues. An in-vivo study done by the University of Gießen confirms the accuracy of digital and conventional full-arch impressions in patients, and results show that among the tested scanners, only Primescan showed no significant deviations to long-span accuracies obtained with conventional impressions.4
A study by Beijing University tested the precision of Primescan and two other intraoral scanners in edentulous jaws. The precision of Primescan was significantly better than the other two scanners for maxilla.5 In trueness of the three scanners, when scanning the maxilla and mandible, there was no significant difference.5
The results of the 2020 in vitro study by the University of Zurich showed that the preparation margin accuracy of Primescan was significantly better than the other intraoral scanning systems involved in the study in local accuracy for single-tooth preparations.2
Dentists like the fact that, with Primescan, it is possible to scan deep regions (up to 20 mm). This allows a digital impression even with subgingival or particularly deep preparations. Almost all tooth surfaces are captured, even when scanning from a very sharp angle.
Our customers are our compass
“The studies confirm again that, with Primescan, we have provided our customers with a high-quality technology that delivers truly impressive results," said Dr. Alexander Völcker, Group Vice President CAD/CAM at Dentsply Sirona. "We continue to add and improve workflows with Primescan as we’re convinced Primescan’s outstanding technology opens the doors for more applications in digital dentistry. Thanks to the technology of high-frequency contrast analysis, Primescan enables our customers to achieve outstanding accuracy in digital impression. And the extensive positive feedback from our respected experts and users all over the world, our most important compass, encourages us to continue to lead in this area’s development and innovation.”
“As a dentist, my expectation of myself is to deliver exceptional results for every one of my patients.” said Dr. Carlos Repullo, a dentist from Seville, Spain. “And with Primescan I can do so: the scan delivers a precision that one can scarcely imagine being improved. And this also applies to a full jaw scan, which can be prepared exceptionally quickly. This is exactly the quality we need in our practices.”

G-ænial™ Universal Injectable is GC’s strongest direct restorative ever*, and now available in unitip delivery! This innovative material is highly filled and stronger than many traditional paste composites. Thanks to its highly thixotropic viscosity, it adapts very well to the cavity walls and margins and fills any void or undercut, yet is able to retain its shape during placement. It can be used for all cavity classes, as it is strong enough for posterior restorations (without capping), and displays optimal esthetics for the anterior area. Now, GC America Inc. is pleased to announce the availability of G-aenial™ Universal Injectable composite in a convenient, single-use unitip delivery system, effective October 15, 2020.
A lot of thought has been put into the handling of this unique composite. GC’s R&D developed a new technology called Full-coverage Silane Coating (FCS) to improve the coupling between the fillers and the matrix. As a result, it is easy to extrude, does not slump or stick to the tip and displays amazing wear-resistance.
Because G-ænial™ Universal Injectable has flexural strength and wear-resistance comparable to conventional paste composites, expanded indications are possible. Its high thixotropy enables it to keep its shape or to spread on the tooth surface depending on the constraint applied on the material, which is why it can be used for many applications with simplified techniques. It is indicated for all restoration classes, from Class I to Class V, and to build margins or restore occlusal surfaces, cusp by cusp. Because the material is so wear-resistant, it is well-suited for the direct restoration of worn tooth surfaces using the injection moulding technique.
On top of these handling advantages, this composite also offers great esthetic possibilities with 16 beautiful shades including opaque and enamel shades. The homogeneous dispersion of the material’s ultra-fine barium particles helps to achieve beautiful gloss retention for a long-lasting shine. Additionally, the high radiopacity of 252% allows for easy follow-up on your restorations.
G-ænial™ Universal Injectable offers you easy restorative options, without having to compromise on durability or esthetics. Now, with the availability of single-use unitips, clinicians can choose the best delivery for their patients and practice. For more information, please visit: www.gcamerica.com.

Roughly half of U.S. dentists experienced verbal or reputational aggression by patients in the past year, and nearly one in four endured physical aggression, according to a new study led by researchers at NYU College of Dentistry.
The study, published in the October issue of the Journal of the American Dental Association, is the first to document aggression toward dentists in the United States.
Workplace aggression toward health care professionals is common, with health care settings second only to law enforcement in the rate of violent incidents. However, there are no studies of aggression toward dentists in the U.S.—a workforce of 200,000—and only four studies have been conducted in other countries.
“Workplace violence toward health care professionals is both widespread and widely overlooked,” said Kimberly Rhoades, a research scientist in the Family Translational Research Group at NYU College of Dentistry and the study’s lead author. “The purpose of this study was to provide an initial estimate of rates of patient aggression in dental practices in the United States.”
Rhoades and her colleagues surveyed 98 dentists practicing in the New York City metropolitan area; the dentists had been working an average of 17 years. Participants completed a confidential online survey assessing whether they had experienced any of 21 specific types of aggressive behaviors from their patients, including types of physical (e.g. being pushed or kicked), verbal (e.g. being insulted or sworn at), and reputational (e.g. threats of lawsuits or posting nasty comments on social media) aggression.
A substantial proportion of dentists reported experiencing aggression from patients in the past year, including physical (22.2%), verbal (55%), and reputational (44.4%) aggression. An even larger proportion of dentists surveyed were subjected to physical (45.5%), verbal (74%), and reputational (68.7%) aggression at some point during their career. These rates of patient aggression toward dentists are high and comparable with those reported in other health care settings.
Rates of aggression did not differ by dentists’ sex, race, ethnicity, specialty, age, years practicing, or average number of patients treated per day.
The rates of physical and reputational aggression toward dentists were similar to those from a parallel study by NYU researchers of aggression toward dental students published earlier this year in the Journal of Dental Education. However, practicing dentists experienced less verbal aggression from patients than dental students (55% versus 86%), suggesting that additional experience may reduce the risk of verbal aggression.
“Dentistry is rife with situations that can elicit strong negative emotions, such as fear, pain, distrust, and anger. Many patients also experience high levels of anxiety and vulnerability, which may increase negative responses or aggression,” said Rhoades. “Establishing that aggression toward dentists is a problem and how often it occurs can help us develop interventions to prevent aggression in dental practices.”
The researchers note that, while a larger, national study is needed to determine the true prevalence of aggression in U.S. dental settings, dental practices should consider implementing training that incorporates strategies for handling workplace violence. Training could address how to prevent patient aggression, and manage or de-escalate aggression when it does occur.
In addition to Rhoades, study authors include Richard E. Heyman and J. Mark Eddy of NYU College of Dentistry; former and current NYU dental students Nicole C. Haydt, Jacqueline E. Glazman, Zachary F. Dispirito, Sammie Jo Fat, Charlotte M. Guerrera, and Allison N. Rascon; and Mark S. Wolff of the University of Pennsylvania School of Dental Medicine.

Formlabs, a leading 3D printing company, today announced two new proprietary materials, Rigid 10K Resin and a reformulation of Draft Resin, to expand design capabilities for users and enhance what’s possible with 3D printing. The reformulated Draft Resin enables users to print up to four times faster than currently available resins, while maintaining the highest degree of accuracy and improving part quality. The new formulation offers improved surface finish, postprocessing requirements, and a new grey color. Rigid 10K Resin is the stiffest material in Formlabs’ entire portfolio, meeting engineering and manufacturing customers’ need for a stiffer, more heat and chemically resistant material. Together, Draft Resin and Rigid 10K Resin complement the natural progression of product development, supporting customers from quick initial designs through high performance parts.
“One of the most powerful advantages of stereolithography (SLA) 3D printing is the wide range of printing materials,” said Max Lobovsky, CEO and co-founder of Formlabs. “Our customers don't just need parts with the right geometry, they also need the right material properties. With our expansive library of resins,our users can make anything from surgical tools, to retainers, to jigs and fixtures and everything inbetween.”
The reformulated Draft Resin features and benefits include:
●Prints up to four times faster than standard materials
●Minimal support removal, wash, and cure times.
○Live 3D printing demos
Aside from use in manufacturing, engineering and product design, the new Draft Resin is also key withint he dental and orthodontic fields. Capable of printing aligner and retainer models in-house in under 20 minutes, Draft Resin opens up chair-side or same-day delivery for orthodontic practices. For dental labs, Draft Resin enables improved throughput and efficiency, producing over 95 models per day on a Form3BL. Compared to Formlabs Grey Resin, which can print eight models in 9 hours and 48 minutes, Draft Resin accomplishes this in just one hour and 30 minutes. From set-up to post-processing, Draft Resin builds on Formlabs’ easy-to-use, accurate, and reliable 3D printers, while bringing print speeds to newlevels.
Rigid 10K Resin
Rigid 10K Resin features and benefits include:
