Orthodontics and The Technology Behind Invisalign Braces

You may wonder what goes on with your Invisalign braces between the time that your orthodontist takes impressions of your teeth for your clear braces and when you receive your first set of aligners.

State-of-the-art computer technology plays a vital role in the process of creating your Invisalign braces. In fact, Invisalign's high-volume, customized orthodontics manufacturing process is the first of its kind in the world.

Below are some of the ways advanced computer technology in used in the manufacture of Invisalign invisible braces.

• To ensure a high degree of accuracy throughout the process, your orthodontists take impressions of your teeth.
• Your orthodontics professional then sends Invisalign your dental impressions which are used to make plaster models of your teeth.
• Using advanced imaging technology, Invisalign transforms the plaster models of your teeth into a highly accurate 3-D digital image.
• From your approved ClinCheck® file, Invisalign uses laser scanning to build a set of actual models that reflect each stage of your dental treatment plan.
• Using the Internet, your orthodontists review your ClinCheck® file - if necessary, adjustments to the depicted orthodontics plan are made.
• A computerized movie - called ClinCheck® - depicting the movement of your teeth from the beginning to the final position is created.
• Your customized set of aligners for your Invisalign clear braces are made from these models, sent to your orthodontist, and given to you. You wear each aligner for about two weeks.
• After wearing all of your orthodontics aligners in the series, your crooked teeth are gone and you've got the beautiful smile you've always wanted.

How Malocclusion - or Bad Bite - Can Be Fixed by Braces for Teeth

It is ironic that one of the most common dental disorders is also the most neglected. The way the teeth fit together when the jaw closes and chews is of profound importance to the long-term health of your teeth.

If surfaces of the teeth interfere with how the jaw moves, the teeth can be worked loose or the enamel can be worn away. The muscles that move the jaw are very powerful and can do major damage to the teeth when the biting surfaces don't fit together properly.

The problem can be compounded if teeth interfere with functional muscle patterns, the jaw muscles will attempt to "erase" the part of the tooth that interferes by grinding against it all the more. This can lead to even more severe wear or it may crack off a cusp or split the tooth. Or it may loosen the tooth or cause it to move out of alignment. The excessive muscle activity often results in pain in the muscle itself. All of the jaw muscles can become sore including the temporal muscles that are the source of many so-called tension headaches.

Some excessive muscle activity may be caused by emotional stress. But with some special exceptions, damage done by stress induced grinding and clenching can be minimized to a manageable level by equalizing the biting surfaces that are in conflict with jaw movements. Proper fitting of braces for teeth can solve the problem by gently moving the teeth into a more optimal position.

The power of the jaw muscles may surprise you. Some people can exert over 900 pounds of compressive force with their jaw muscles so you can imagine how much damage such force can do when you close into a single tooth and then work it from side to side. The effect is very much like working a fence post loose as the bone around the root breaks down. If you can put your finger on any tooth in your mouth, and then squeezing your teeth together causes the tooth to move, you can be sure that it is just a matter of time before there will be a problem with that tooth.

Sometimes the muscle forces that work the tooth sideways stimulates bone around the root to build up and become stronger. When that happens, the tooth actually bends in its socket and this creates a microscopic chipping away close to the gum line to form a deep groove in the tooth. This is called an abfraction. These deep grooves at the gum line are often mistaken for toothbrush abrasion, but scientists have shown us that the grooves are actually the results of bending of the tooth in its socket. These grooves can lead to much sensitivity in those teeth because the opening into the tooth exposes nerves that can be exquisitely sensitive. Correction of the bite with Dental Braces to remove excessive lateral forces on the teeth in most instances either eliminates the sensitivity completely or reduces it to a much more acceptable level.

Patients should be aware that much confusion surrounds the importance of a harmonious bite, including many misconceptions that have been fostered by flawed research that has failed to properly relate the bite interferences to the position and condition of the temporomandibular joints. Knowledgeable clinicians, however, are very much aware of this relationship and can achieve excellent results with braces for teeth that will help make both your teeth and your jaw muscles more comfortable by bringing your whole biting into harmony.
