How Invisalign Works
- Step 1
The patient meets with Dr James Walmsley – an Invisalign-certified dentist 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 model’s and start-to-finish 3D animations of the patient’s personal treatment plan.
- Step 3
Dr James Walmsley reviews the 3D models and animations and approves the treatment plan. From these images, Invisalign manufacturers 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.
