Invisible Braces: The Orthodontics Industry Goes Wireless
A new high-profile start-up company, Align Technology, says its 3D computer imaging and manufacturing systems are key to straightening adult teeth without uncomfortable metal braces. Their system, called Invisalign (www.invisalign.com), utilizes 3D scanning hardware, automatic surfacing software, 3D animation programs, and rapid manufacturing systems --powered in part by Geomagic technology --to produce customized, removable, clear plastic appliances called "aligners." Combined with an orthodontist's treatment plan, these retainerlike aligners provide an innovative alternative to traditional braces.
"Align Technology will make history as the first company to lead the wave of mass customization in the 21st century." -- Ping Fu, President and CEO, Geomagic
How Invisalign Works
-
Step 1
The patient meets with an Invisalign-certified orthodontist who takes an impression and x-rays of the patient's teeth, prescribes a treatment plan, and sends the impression to the Align Technology lab. -
Step 2
At Align's lab, a physical model is cast from the patient's impression. That model is then digitized using a 3D scanner. Next, the data is imported into the Invisalign computer system, where it's used to produce precise, manufacturable digital models and start-to-finish 3D animations of the patient's personal treatment plan. -
Step 3
The orthodontist reviews the 3D models and animations and approves the treatment plan. From these images, Align Technology manufactures a unique set of clear, plastic aligners that are custom-fitted to the patient's teeth and mouth. -
Step 4
The patient wears each stage of aligners for approximately two weeks before switching to the next in the series. Week by week, the patient's teeth are straightened, millimeter by millimeter. Total treatment time is similar to traditional braces and usually ranges from six to 24 months depending on the complexity of the case. A single patient's treatment series may contain up to 60 pairs of upper and lower aligners.
"Our rapid design and manufacturing processes require automation, throughput, and customization -- all of which Geomagic has the unique ability to provide." -- Zia Chishti, CEO, Align Technology
The Invisalign system has received FDA clearance, meeting all medical device specifications. Geomagic's patented technology and engineering services enable Align to optimize its manufacturing process to meet current demand and increase capacity in the future.
"Imagine viewing a 3D animation of the next two years of changes to your daughter's teeth -- the day after her first visit to the orthodontist." -- From Geomagic's first corporate brochure, 1997
