Dentsply Sirona and Panthera Dental announce collaboration for custom-made sleep devices

CHARLOTTE, Quebec, CANADA: Dentsply Sirona’s intraoral scanner Primescan, launched in 2019, enables high-precision digital impressions with outstanding imagery. Working with Primescan offers numerous advantages: It can be used for patient consultation, treatment planning in implant dentistry and orthodontics, and for restorative treatments.

With the collaboration between Dentsply Sirona and Panthera Dental, announced recently, dentists can now use the precise scans in a validated workflow as a basis to create a custom-made digital sleep apnea device (D-SAD). The outstanding quality of the intraoral scan data delivers reliable data for the high-quality custom-made D-SAD mandibular advancement device (MAD), indicated for people suffering from obstructive sleep apnea and snoring.

Three steps to D-SAD: Scan, send and treat

Thanks to Dentsply Sirona’s Primescan, a complete and accurate full-arch scan is possible in as little as a minute to give the dentist immediate control of a 3-D model. The outstanding accuracy and reliable quality of Primescan delivers reliable data for the Panthera Dental D-SAD custom-made sleep device. This saves time and nearly eliminates the necessity for adjustments during patient visits.

The data transfer to Panthera Dental is fast and secure: For North America, Germany, France, Belgium, Netherlands, Luxembourg, United Kingdom, Australia and New Zealand the data will be transferred securely via the Dentsply Sirona Connect Case Center. For other Primescan and Panthera Dental countries the data can be sent via STL to Panthera Dental through their user-friendly web portal (regulations per country and availability may vary). With one of the next software versions, there will be a full integration in the Connect Case Center for all Primescan and Panthera Dental-validated countries.

One advantage is that besides Primescan, no additional equipment is needed. After scanning the patient’s complete jaw and the bite registration for the protrusion, the scan data can be sent directly to Panthera Dental, either using the Connect Case Center or via STL-file. Within 15 days, the D-SAD will be designed and manufactured by Panthera Dental’s proprietary CAD/CAM process in their 4.0 manufacturing plant using numerous digital, robotic and automated technologies. It is then shipped back to the dental professional via multinational express delivery service. The dentist receives a custom-made sleep device and can start treatment immediately.

The individualized and fast result distinguishes the dental practice in its treatment of snoring and sleep apnea, and allows for happier, healthier patients with improved quality of life.

A fast and accurate solution for OSA and snoring

Physical and psychological problems that sleep apnea can cause should not be underestimated. If sleep is constantly disturbed, this can have serious effects on mental and physical health. Currently, three main treatment solutions are recommended by experts: lifestyle modifications (weight loss and exercise), continuous positive airway pressure (CPAP) and mandibular advancement devices (MAD). However, sleep masks (CPAP) have considerable compliance issues with 50 percent and 83 percent of patients being non-compliant after six months and five years respectively.[2] Patient compliance of mandibular advancement devices (MADs) remains 86 percent after over three years of use.[3] Thanks to Panthera Dental’s D-SAD, patients with obstructive sleep apnea (OSA), and those who refuse or are noncompliant to continuous positive airway pressures (CPAP) therapy, have a comfortable and effective treatment option available.

Dr. Shouresh Charkhandeh, dentist and dental sleep medicine educator from Canada, says: "Over 1 billion people worldwide suffer from sleep-related breathing disorders such as obstructive sleep apnea. Many of them can benefit from oral appliance therapy (OAT). We need to safely simplify OAT and make it predictable in order for many dentists to get involved in providing this life-saving treatment to patients. The validated digital workflow solution between Primescan and Panthera Dental, which combines Primescan’s impressive accuracy, efficiency and ease of use, with Panthera Dental’s precise and versatile manufacturing, enables dentists around the world to help many suffering patients live a longer, better and healthier life and provide an alternative solution to CPAP therapy."

Panthera Dental’s D-SAD is made out of 100 percent medical grade biocompatible type-12 polyamide nylon. This cutting-edge material is light, smooth, strong yet flexible, very durable and resistant to bruxism. A wide range of plateaus and bands are available and allow for over 300 standard design combinations as well as maximized tongue space. Additional customization is possible, and the D-SAD can be adapted to every possible patient morphology, from basic to the most complex. It is a uniquely simple and easy to care for dental appliance.

The D-SAD’s unique titration mechanism uses interchangeable rods made of the same biocompatible polymer as the device, designed to not elongate and resist to bruxism. The length of the rods varies from 16 to 34 mm and can be adjusted in 0.5 mm increments for an accurate and customized advancement. Moreover, they do not disengage during sleep thanks to a patented connection system and they are easily replaced.

"We are fulfilling an explicit request from customers and providing added value for dentists working with Primescan," said Dr. Alexander Völcker, group vice president CAD/CAM at Dentsply Sirona. “The combination of Panthera Dental’s Digital Sleep Apnea Devices and Primescan is a great example of what can be achieved when a dental workflow starts with an intraoral scan. The digital technology integrates seamlessly into the daily workflow, enabling clinicians to provide a fast and accurate solution for sleep apnea and snoring."

Beatrice Robichaud, co-founder and vice president of marketing & customer experience at Panthera Dental, said: “Our collaboration with Dentsply Sirona is a natural fit that will synergize both our companies’ recent technological advancements in the field of CAD/CAM solutions. Dentists worldwide will benefit from the predictability of the validated Primescan workflow while delivering an accurate, completely customized digital sleep apnea device to their patients, for greater patient satisfaction and quality of life.”

The Panthera D-SAD received FDA 510(k) clearance for snoring and obstructive sleep apnea has the CE mark and complies with the Canadian Medical Devices Regulations.
