Anthony Gillit, digital laboratory specialist at Henry Schein Dental, looks at the latest digital technology that’s transforming laboratory workflows.
Today’s digital technologies are working to transform every aspect of the dental industry, and dental laboratories are no exception. The advances, especially in state-of-the-art milling systems, CAD/CAM software, materials and 3D printing, not only offer technicians the chance to deliver custom-made solutions with speed and precision, but ultimately make laboratories more productive, efficient, and profitable.
When it comes to in-lab milling, the Programill PM7 from Ivoclar Vivadent is a high-quality bench top milling machine. With an 8-disc changer, the PM7 is capable of milling a wide variety of materials in wet and dry mode, from wax and PMMA through to glass ceramic and zirconia, including Zirlux, in a variety of shades. The machine automatically switches from wet to dry extremely quickly, reducing the often lengthy ‘drying out’ time, while also speeding up overall production.
The high dynamics and efficiency of the machine result in fast and precise manufacture and technicians have commented that the detail on the occlusal surfaces of restorations is superb. Its 20-position tool changer means a multitude of different tool sizes can be selected during the milling process and production can run 24/7 without constant supervision, freeing up technicians’ time for the next design or characterisation.
The PM7 features an integrated ioniser and automatic self-cleaning function that removes minute particles of dust and plastic in the milling chamber that can be a cause of milling source failure. This feature also helps to lengthen the life of the tools.
Rise of 3D printing
3D printing is now starting to have quite an impact in digital dentistry and the application of this technology is now starting to gather pace, especially with the advances in materials that can now be 3D printed.
In the case of implant work, technicians need an articulated model to work from to ensure an accurate fit. A printer such as the Asiga Max 3D can produce such models in less than an hour. Offering exceptional accuracy and speed, the Asiga is also ideal for the manufacture of orthodontic aligners, crown and bridge, surgical guides, custom trays, and partial dentures.
The Asiga Max 3D uses projection technology. This involves projecting a light onto the resin to cure an entire layer in one go before moving on to the next. It’s Smart Positioning System (SPS) uses a series of positioning encoders that read the exact position of the build platform during each layer approach. This ensures that subsequent layers are only exposed and formed once the build platform target position has been reached. It has an open material system, so technicians have the freedom to choose the most suitable material for the job in hand, from any material manufacturer.
I first began working with digital technology over 16 years ago and even then it was obvious that the future for dentistry was going to be digital. We are now seeing digital techniques become the norm and this is really starting to change the dental landscape.
Digital technology is improving technicians’ lives, doing away with more routine manual tasks and allowing them to benefit from faster, cleaner, more efficient and optimised digital workflows. For anyone looking at the future of their business, investing in digital technology really is the only way forward.
Henry Schein Dental combines a wide choice of digital technology solutions with all the knowledge, service, training and support needed to help laboratories navigate the rapidly changing world of digital dentistry.
