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!

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.

We are continuously working to improve the quality and convenience at Riolo Orthodontics.  You can contact us at SeattleOrthodontist.com to make an appointment or just ask us a question.

Some Questions and Answers Regarding Incognito Braces

Q: Would that treatment plan be as effective using braces behind the teeth as conventional braces?

A: Custom made brackets are more efficient than standard stock brackets that are mass produced for the “average” person.  The standard prescription in the stock bracket is not ideal for any individual.  It is produced to be as close to the correct prescription for the greatest number of patients and thereby is correct for no single individual. Theoretically, custom lingual is more efficient especially in terms of treatment time and precision. The literature show this and I have noticed a difference clinically; that being said it is possible to get an excellent result with either product.Read more on Some Questions and Answers Regarding Incognito Braces…
