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!

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!

Riolo Orthodontics: expand our 3D printing capabilities

INNOVATION AND CUTTING EDGE OF DIGITAL DENTISTRY

Riolo Orthodontics has been using our FormLabs2 printer for a year and it has improve care and convenience for our patients.  3D printing enables us to provide same day retainers and incorporate provisional replacement teeth into your orthodontic appliance.  These advantages have resulted in a large increase in demand for these printing services. Our practice has grown to the point that we have decided to expand our printing capabilities and have acquired a new Juell 3D printer made by Park Dental

3D printing improves orthodontic care
3D printing allow same day retainer delivery and replacement of missing anterior teeth integrated into the patients orthodontic treatment

Our 3D printing technology has improved care for our patients by enabling us to provide retainers the same day as the braces removal and printing temporary replacement teeth used during treatment.

3D PRINTING IN A FLASH

  • JUELL 3D is one of the fastest 3D printers on the market today, Print orthodontic models for complete clear aligner treatment in under 30 minutes without compromising resolution or accuracy.
  • Builds at speeds as fast as 7 seconds per layer!
  • Unbelievable 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.
  • Print from an intra-oral or tabletop scanner using .stl, .obj, .3ds or .amf file.
  • Print jobs are scalable. Build a quadrant or 18 arches with supports! The layer build time remains the same.

How the Juell 3D printer works

First we take a scan with our intra-oral digital scanner. subsequently, the digital model of the teeth is edited, a base is added and holes are filled and the model is smoothed out. The digital model is then uploaded to the 3D printer. The Juell printer employs SLA (Stereolithography) printing technology which hardens photo sensitive resin layer by layer with a ultraviolet light.  Each small layer builds on the last.  This SLA technology is used in the production many orthodontic appliances including Invisalign.

The benefits of the Digital orthodontics and 3D printing for patients

Our TruDefinition intra-oral scanner is less invasive and more convenient than the traditional impressions.  The 3D scan and 3D printing is also more accurate than impressions so the retainer will fit your teeth perfectly.  Since the these digital models are printed in house we can turn these models around the same day!  We also can fabricate custom pontics (replacement teeth) in house and integrate these teeth into your custom orthodontic appliance system.

Retainers for a lifetime!

All of our models are stored digitally and we give our patients copies of their final printed models of their teeth.  In addition, as a direct result of our 3D printing capabilities Riolo Orthodontics now offers replacement retainers for a lifetime.

 

3D Printer

Form-2-printer-three-quarters-Hart

The office now has a new Form Labs 3D printer

We use the 3D printer to print models of your teeth and create retainers, aligners and many other orthodontic appliances. Combined with the 3D digital scanner it can create models of your teeth that are much more accurate. Furthermore this method will create a more accurate retainer compared to the traditional method of taking a mold of your mouth. After you get your retainer you can keep the 3D printed version of your teeth. This model can be brought in to make a new retainer if you lose your retainer or your dog happens to chew it. We also keep a digital copy of your teeth that can be reprinted if you happen to lose both your retainer and 3D printed model.

How the 3D printer works

First we take a scan with our intra-oral digital scanner. Next the file is edited to have a base added and so that it is smoothed out. After the file has been edited it is uploaded to the 3D printer. Our Printer employs SLA (Stereolithography) printing technology which hardens resin with a ultraviolet laser in very small layers building upon each other. After the print the build supports of the model are removed. The model is then soaked in a bath of isopropanol for two sessions of ten minuets. After that you are left with an orthodontic model. This SLA technology is used in the production many orthodontic appliances including Invisalign.

The benefits of the 3D printer for patients

The intra-oral scanner is less invasive than the traditional impressions. Since the these digital models are printed in house we can turn these models around the same day!  We now have the ability to produce retainers the same day as the braces are removed.  This means there is no chance the teeth will move before you get your retainers. The 3D scan and 3D printing is also more accurate than impressions so the retainer will fit your teeth perfectly.
