"Invisalign" is a highly marketed technique for straightening teeth with a series of fairly invisible plastic repositioning trays. Each aligner tray is slightly different to the previous tray and gradually moves the teeth a bit further with each tray.  Invisalign is the original and most researched brand, however now there are also some other competing clear aligners.

It is most suited to adults or sometimes teenagers with mild problems, who don't want anything obviously visible, and who would be both patient and disciplined enough to wear them exactly as instructed.

Stuart officially completed the Invisalign accreditation course in Arizona in 2016.

It can work well in certain cases, however there are drawbacks.

* If the trays are forgotten or left out for a few days, it may mean going back several stages to earlier trays, until finding one that fits, and extending the treatment time which in many cases is more than 2 years

* Often the technique requires a significant amount of tooth reduction (drilling away enamel between the teeth) to allow the teeth to fit into place. We can minimise this however by starting with expansion appliances to enlarge the jaws and dental arches

* There may be as many as 40 separate trays in the process and if any are lost, new trays will be needed at an extra fee

* The cost is greater than most other techniques, as there is a large laboratory fee which must be passed on to the patient


Sometimes we will use our own invisible repositioning trays to finish off a case at no extra charge, or we may do a minor case with only a few  trays and no braces. Although this is not technically "Invisalign" it is the same principle.
