Invisalign Invisible Braces in Greenwich, South East London

Invisalign invisible braces

Invisalign is an alternative to wire braces that uses transparent, incremental aligners to adjust teeth. It is manufactured by Align Technology, a multinational medical device company headquartered in San Jose, California. The Invisalign treatment process involves taking a mould of the patient's teeth that is scanned in order to create a computerized model. Using the doctor's treatment plan, the computer model creates stages between the current and desired teeth positions that are used to create moulds for individual aligners.

How invisalign is carried out

Once the Orthodontist decides that a patient is a suitable candidate for Invisalign, treatment begins with the Orthodontist taking x-ray, photographs, a bite registration and polyvinyl siloxane impressions of the patient's teeth and gums. The orthodontist completes a six-page form with a diagnosis and treatment plan. Dental impressions are sent to Align Technology and scanned using a computerized tomography scanner which creates a digital 3D representation of the patient's teeth. Computer technicians move the teeth to the desired location in a software program called Treat, which creates stages between the current and desired teeth positions for individual aligners. About six to forty-eight aligners may be needed depending on the patient, with each aligner moving teeth up to .33 millimeters.

A computer graphic representation of the projected teeth movements is provided to the doctor and patient in a software program called ClinCheck for approval or modification before aligners are manufactured. The aligners are modeled using CAD-CAM (computer-aided-design and computer-aided-manufacturing) software and manufactured using a rapid prototyping technique called stereo lithography. The moulds for the aligners are built in layers using a photo-sensitive liquid resin that cures into a hard plastic when exposed to a laser. The aligners are made from an elastic thermoplastic material that applies pressure to the teeth to move into the aligner's position. Patients that need a tooth rotated or pulled down may have a small tooth-colored composite attachment bonded onto certain teeth. Reproximation, (also called interproximal reduction or IPR and colloquially, filing or drilling), is sometimes used at the contacts between teeth to allow for a better fit.

Each aligner is intended to be worn 20 hours a day for two-to-three weeks. On average the treatment process takes 6-28months. Refinements may be ordered by the Orthodontist during the treatment process. The aligner is removed for brushing, flossing and eating. Once the treatment period has concluded, the patient is advised to continue wearing a retainer at night for the foreseeable future.

Lingual braces

Lingual braces (INCOGNITO) are another method of moving teeth invisibly. They are an excellent system for aligning teeth at the same time deliver improvements to your bite. The word lingual comes from the Latin word for tongue ‘Lingua’, to describe orthodontic brackets fitted behind the teeth, instead of on the front surface of the teeth. While the patients can feel the brackets with their tongue, and in the early days of treatment many find eating and speaking a little challenging, the plus point is that no one can see the braces! Invented in the 1970s, the lingual systems have been refined over the years. Now that the brackets are smaller and neater they are more easily concealed at the back of each individual tooth. A wire is connected to each bracket and exerts force to move teeth into new positions over a period of days, weeks and month.

Damon braces

The Damon braces are a revolutionary method of orthodontic treatment. A full and natural 10-tooth smile is achieved via Damon braces using light biologically – sensible forces which are designed specifically to improve your smile.

  • Damon passive self-ligating braces eliminate the need for elastic band or metal ties and you can now experience orthodontic treatment without tightening
  • Light high- technology shape – memory wires, move teeth faster and need fewer adjustments
  • A clinically proven treatment approach that aligns your teeth and enhances your facial aesthetics – usually without extraction or rapid palatal expander.

The above three treatment methods when used simultaneously by Damon System certified doctor can lead you to achieve a faster result, with fewer appointments and greater comfort!

The Damon system uses a slide mechanism to hold the wire allowing the teeth to move more freely, quickly and comfortably.

The absence of elastic ties makes it easy to clean the teeth and thus reduces the formation of plaque. The Damon System is also available in Clear brackets for patients who would prefer a more discreet option.


Retainers are often used near the end of a course of orthodontic treatment. Retainers hold newly fixed teeth in place while the surrounding gum and bone adjusts to the new position of the teeth and can be either removable or fixed.

Your orthodontist will advise you when to wear your retainer. It is likely that if you stop wearing your retainers there will be some tooth movement. Changes in the position of your teeth can continue throughout life and are part of the normal ageing process. The only way to have permanently straight teeth is to wear a retainer on a part-time basis for life.

Removing teeth

In some cases, it may be necessary to remove a tooth to correct the position and appearance of nearby teeth. But as a result of recent advances in orthodontic treatment, removing teeth has become much less common.

However, if baby teeth have been extracted there is a greater likelihood that adult teeth need to be extracted as part of orthodontic treatment.
