How Your Invisalign Aligners Are Custom Fitted for You

Invisalign® is a system of transparent aligners that are custom-made to fit a person's teeth. Like braces, it corrects alignment by delivering different levels of pressure to individual teeth. Since everyone has a unique smile, you will need a custom-made pair of Invisalign clear aligners. This article provides information on how clear aligners are custom-made for patients.

Getting fitted with custom Invisalign aligners

The shape of the aligners allows them to induce force on the misaligned teeth, causing them to move into a straighter position. Clear aligners like Invisalign require an adjustment phase, as with conventional metal braces. As the aligners begin to function, a person can anticipate feeling some pressure. The patient becomes used to their aligners gradually, and the pain and discomfort subside.

The orthodontist will evaluate a patient's teeth to determine the best approach to teeth straightening. If a patient opts for Invisalign instead of traditional orthodontic procedures, we will:

Take an impression of the patient’s teeth

In some cases, the orthodontist may ask the patient to bite down on something that looks like putty. They will create a cast of the patient's teeth from the resultant mold. Most orthodontists nowadays take a digital 3D scan of the patient's mouth using an optical camera.

Design the Invisalign trays

The 3D scan from the camera will be sent into software that will create a model of the patient's mouth. The orthodontist will use the model to plan how each pair of trays will move each tooth to its ideal position. The trays will be custom-made to suit a patient's specific configuration.

Construct the Invisalign trays

The impressions taken by the orthodontist will be utilized to manufacture and sculpt the Invisalign trays in a lab. The aligner-making machine operates similarly to a 3D printer. It prints or mills a set of Invisalign trays based on the orthodontist's designs. There may be five or six sets of trays in each Invisalign series.

Make an appointment with the patient for a fitting

The orthodontist will contact the patient for a fitting when the aligners are available. The patient will be asked about how comfortable the aligners are. The orthodontist will make any necessary modifications to make the device more comfortable for the patient. They will also instruct the patient on how to use and care for the aligners. The aligners are typically worn for 22 hours each day. The patient will need to transition to a fresh set of aligner trays after a while, typically two weeks.
