A group of researchers from the Sri Rajiv Gandhi College of Dental Sciences & Hospital in Bangalore, India evaluated the marginal accuracy of Cobalt-Chromium copings (thin covering of the tooth’s crown portion) fabricated using DMLS, computer-aided milling, traditional casting, and ringless casting and comparatively analyze the marginal discrepancy. They used typodont resin model made of silicone impression material and 40 copings, for which they used 3D laser scanner from 3Shape to obtain an indirect impression of the tooth model, and then used the data to design the coping in 3Shape’s CAD software program, before they were 3D printed on an EOSINT M 270 3D printer from EOS.
A group of researchers from the University of California, Los Angeles (UCLA) are working on using an SLA 3D printing method to manufacture temporary teeth restorations. Temperature Controlled Mask image projection-based stereolithography (TCMIP-SL) processes use a set of horizontal planes to slice a 3D object, and each slice is converted into a 2D mask image. Then, a 2D patterned light beam, which is controlled by a digital micromirror device (DMD), is projected on the surface of a photocurable material, which is then cured layer by layer to build the 3D object.
The largest orthodontic laboratory in the United Kingdom is Ashford Orthodontics, which was founded in 2001 by Sean Thompson. Working with Formlabs Form 2 and aligners models, the new scans sent by the clients are 3D Printed overnight which are then delivered to the clinicians arriving within the next 48 hours. They have gone fully digital, abolishing the traditional route which helps the client in cost and time savings.
Temasek Polytechnic, a university in Singapore, is developing a new technique for better, faster, and cheaper Dental Crowns and Bridges, as a result of 3D printing. The technique involves creation of a traditional impression that is then turned into a form, which is scanned to create a digital model and in turn, the mold for shaping the exterior and interior metal form to attach the prosthetic to the receiving tooth.
Researchers from King Abdullah University of Science and Technology (KAUST) have developed an orthodontic system that uses smart 3D printed braces and flexible, non-toxic batteries. The system consists of a semitransparent, 3D printed dental brace that places two near-infrared LEDs on each tooth, along with one lithium-ion battery to power the LEDs, which provide localized light therapy to the teeth. The redesigned state-of-the-art lithium-ion battery technology are flexible with biosafe encapsulation within the braces to make a smart dental brace.

What does aesthetic dentistry have to offer the discerning dental patient both now and potentially in the not-too-distant future? The possibility of fabricating 3D teeth with antimicrobial properties is already being explored.
There’s no pain or discomfort, and young patients find it “cool” to watch their teeth begin to take shape in 3D on the computer screen. A trip to the orthodontist has suddenly become a high-tech, almost futuristic, experience. In this specific case, taking digital impressions instead of traditional impressions.
Invisalign treatment has been growing in popularity since its launch in 1999, and its reach has spread around the world. Its use of digital scanning, computer modelling and 3D printing enables it to produce customised teeth aligners that steadily move the teeth into place over the period prescribed to each patient.
During the CAD-CAM crown procedure, instead of taking physical impressions, a dentist uses optical or laser scanning technology to capture a digital image of the tooth from all angles. The dental practitioner uses special 3D software to design the crown and sends it to a mill located in the office. The dentist then places a block of porcelain in the mill to form the tooth. Drills in the mill carve and shape the tooth, following the pattern of the mold sent via scan.
We all know technology has the potential to change our lives in so many different ways. But sometimes, there’s a particular area of tech and innovation that goes above and beyond to revolutionize the world; 3D printing is one of them. While 3D printing is still a niche area, it’s growing rapidly.
Researchers were able to produce 3D maps that displayed the location of atoms that are crucial in the decay process. To obtain these 3D maps, researchers used a comparatively new microscopy technique known as atom-probe tomography. The new insight gained about the nanolevel atomic composition of tooth decay helps to prevent dental cavities and maintaining oral health hygiene.
Scientists know a great deal about what enamel looks like. However, they don’t know exactly how it forms. Fortunately, a technique called atom probe tomography now allows researchers to look at the distribution of the various atoms and ions in tooth enamel to see whether there are patterns. The method generates 3D visuals of materials at the atom scale.
"Our [system] will straighten the teeth in incremental steps," said Dan Knoch, who founded iPrint 3D. In the years since, Knoch has adopted ever-more-sophisticated technology — building 3D printers, scanners and software in-house — to fulfill his vision of straightening peoples' teeth.
MIT and the Singapore University of Technology and Design (SUTD) teamed up to create a new kind of structure that can “remember” its original shape, and return to that state even after being deformed. It is able to printed onto a liquid resin using light from a projector, which MIT says is basically what happens when dentists 3D print replicas of teeth or cavity fill.
Teeth Tomorrow dental prosthetics are constructed using 3D dental imaging, customized for each patient’s unique smile.

3D printing provides a high degree of laboratory rationalization as it can satisfy many different dental indications and is also cost-effective. Materials development is central to the adoption of 3D printing in new dental applications.
Some factory bosses have said that 3D printing will never replace mass manufacturing. Perhaps, but it does not have to transform production processes. Additive-manufacturing systems are being mashed together with traditional production methods, which themselves are improving with digital technologies. Even old-fashioned metal bashing and welding is going high-tech.
Josh Stephenson, a graphic designer underwent surgery to remove his left eye, upper left jaw and the roof of his mouth after failure of radiation treatment for malignant melanoma. Using a 3D-scanned and printed copy of Stephenson's skull and scapular bone, Andrew Dawood, a dentist with Dawood and Tanner, recreated his entire jaw.

Periodontist Professor Saso Ivanovski, from Griffith University’s Menzies Institute has announced that he has developed a way to engineer missing bone and tissue in the gums and jaw by using a patient’s own cells after 5 years of research. This will involve taking CT scan of patient's damaged region which will be sent to bioprinter to 3D Print new part and the whole procedure will decrease the significant pain, nerve damage and postoperative swelling. National Health and Medical Research Council has granted it $650,000 for the potential it holds in dental industry.
One of the biggest markets for 3D printed dental devices is in the area of orthodontics. 3D printers enable orthodontic professionals to create all manner of personalized equipment right from their desktops. The technology presented by additive manufacturing allows specialists to dramatically reduce fabrication times and increase technicians’ output times.
STL is the most popular and widespread 3D file format for 3D printing and basic CAD model interchange and is generated directly by the scanning equipment that typically sits within the dentist’s reach. Eliminating the need for the traditional physical teeth impressions, hand-held intra-oral scanners can quickly and comfortably capture a patients’ 3D teeth anatomies without taking messy impressions.
Using a Stratasys Dimension 1200es 3D printer from the New Jersey Institute of Technology, Amos Dudley, a digital design student, 3D Printed his own set of orthodontic aligners. Since it was a DIY aligner costing less than 60$ compared to 1K$, it went viral within a week.
Few people enjoy going to the dentist, but if you can lie back and watch a big screen TV above you or listen to your favorite music, it’s not such a bad way to while away a few hours. Dentistry has certainly changed over the years, but 3D technology has brought about even more dramatic developments in recent years.
The strategy is part of a government push to make Dubai and the UAE a global hub for 3D printing technology by the year 2030. Research is already taking place into the mass production of 3D-printed teeth, hearing aids prosthetics and implants.
