2019 Moyers Symposium: 3D printing Orthodontic Braces

Dr Riolo at the 2019 Moyers Symposium

Seattle Orthodontist Chris Riolo spoke at the 2019 Moyers Symposium giving a lecture titled, Digital Technology in Orthodontics: a custom appliance revolution on the horizon.  We presented progress we have made developing a “in-house” 3D metal printed custom orthodontic appliance system.  Dr Riolo began by explaining  that orthodontic is experiencing “disruptive innovation”.

In health care, disruptive innovation involves technologies, products, or services that are cheaper, simpler, and more convenient, making it possible for less-expensive professionals to provide advanced services in affordable settings, or even for patients to care for themselves.

Disruptive innovation in the orthodontic market place has taken the form of the “Direct to Patient Care Model”.  This direct to patient care model is represented by corporate providers such as Smile Direct Club (SDC), Candid Co, Byte, Smile Love among others.

We have designed and 3D printed a custom lingual orthodontic appliances in Chrome Cobalt

These custom orthodontic braces where designed using off the shelf CAD software, Rhino.  The custom design brackets are then exported and 3D printed using a Concept printer.  The brackets are printed in chrome cobalt using laser sintering technology.  You can see the digitally design custom bases with their adaptors in the figure below.

These digitally design custom orthodontic braces where design using Rhino and 3D printed using a Concept printer.

We are continuing to develop this system and developing the software used to facilitate the digital design process.  This is an opportunity to move the work flow associated with the fabrication of the custom appliances used in the care of our patients back into our private clinics, for the benefit of our patients.

 

Next Gen Orthodontics: 3D printing to fabricate In-house custom appliances

In-house custom orthodontics is on the horizon.  With the advent of of accurate and inexpensive resin 3D printing it is now obvious to many that in-house clear aligners are the future of specialty orthodontic care.  As market penetration of intraoral scanner approaches 100% among orthodontic specialists the means to manifest these “models” physically cannot be far behind.  Over the next 5 years there will be an explosion of resin 3D printing in orthodontic office around the world.

Once an orthodontist has the ability to manufacture a same day or same appointment Essix type retainers using their 3D printers instead the alginate and stone technology from the last century; how far behind can be in-house clear aligner for the correction of minor problems such as food impaction spaces, minor rotations and orthodontic relapse?

3D printing has the potential to revolutionize orthodontics.  Rather than working with third party entities to purchase stock fixed orthodontic appliance systems or in some cases using third party entities for the fabrication custom fixed appliance systems such as Invisalign or Incognito we will soon have the ability to fabricate these appliance systems in-house.  We believe that many cutting edge orthodontist will soon be printing in-house custom appliances for their patient using both resin and metal 3D printing technology.  At Riolo Orthodontic we have been employing these technologies to improve the care we offer our patients.  We are dedicated to providing the best possible orthodontic care aesthetically.  We believe that not only should your smile look great after treatment but it should also look great during treatment!

2018 AAO American Association of Orthodontists (AAO) meeting

 

The 2018 AAO, American Association of Orthodontists held their 2018 annual meeting in Washington DC.

The 2018 AAO, American Association of Orthodontists held their 2018 annual meeting in Washington DC. May 4th through May 8th.   Chris Riolo and Cali Kaltschmidt from Riolo Orthodontics presented 6 hours of workshops and lectures to both doctors and staff from around the world.  Our Events started on Friday May 4th with 3D Printing workshops at 1:00 and 3:00. The workshops presented by both Cali Kaltschmidt and Dr Riolo were titled “From the Scanner to your Hand”  and consisted of a short presentation on 3D printing technology including SLS and DLP printing.  The lecture was followed by a hands on STL editing session lead the Cali using Meshmixer.  Breakout groups followed, participants were assigned to 1 of 3 printing groups to print their edited dental arches.  All of the participants enjoyed one on one time with Dr. Riolo Cali and the printer techs while the dental arches printed.

Moonray, Juell and Formlabs2 printers were available at the 2018 AAO workshops for the participants; each of the participants spend time with the printing software required to format dental arches on each of these printers.

Riolo Orthodontics uses the JUELL 3D-2 is one of the fastest 3D printers available for orthodontic practices today.

The JUELL 3D-2 is one of the fastest 3D printers available for orthodontic practices today. The Juell printer is capable of printing orthodontic models for complete clear aligner treatment in under 30 minutes without compromising resolution or accuracy. The Juell printer builds at speeds as fast as 36mm per hour with accuracy achieved by using enhanced UV/DLP/LED  technology and JUELL 3D Flash OC software to project an HD image with 1920 x 1080p resolution.  With the Juell printer we can print from an intra-oral or tabletop scanner using .stl, .obj, .3ds or .amf file formats. Cali and Doctor Riolo also presented a 2 hour staff lecture on 3D printing at the 2018 AAO meeting in Washington DC.  This lecture covered topics ranging from 3D printing technology to editing raw STL files and digital workflow associated with “In-House” clear aligners.  Cali also presented 3D printing applications associated with provisional tooth replacement.  On Sunday, Dr Riolo Presented his lingual orthodontic lecture for the doctors scientific program.  Dr. Riolo covered material related to custom orthodontic appliance and the impact these appliance can have to improve patient care.  Almost half of our patients at Riolo Orthodontic are treated using some sort of lingual appliance.  At Riolo orthodontics we use Incognito, Harmony and SureSmile systems to treat our adult patients so that no one knows they are even wearing braces!
