What is Invisalign® ?


Invisalign is a system of digitally-designed clear removable aligners to straighten teeth

How does Invisalign work?


A set of moulds/digital scans of your teeth are taken to create your virtual Invisalign treatment plan (Clincheck). The Clincheck shows the tooth movements required for overall teeth alignment in a virtual 3D simulation. This is previewed BEFORE starting your treatment. 



A series of customised clear aligners based on the Clincheck stages are worn to gradually move your teeth. Each aligner is slightly different from the last.



How long does Invisalign treatment take to complete?


Treatment duration depends on the case. The average Invisalign treatment in Singapore runs for about 20-30 months because of the nature of orthodontic problems in the population which is distinct from cases done in the USA and Europe.


What is the Invisalign treatment process like?


Step 1: Consultation & Assessment


During your initial consultation, we will first discuss your treatment goals with you. A clinical assessment is also done to ensure that you are suitable for Invisalign. Following the assessment, photos, moulds and X-rays of your teeth will be taken to design your treatment plan.



Step 2: Virtual Treatment Plan (Clincheck)


The photos, moulds and x-rays will be sent to Invisalign to create a virtual 3-D model of your teeth as well as to plan the tooth movements required at each treatment stage. This virtual 3D simulation is called a Clincheck. Once the Clincheck has been explained to you and approved, your unique Invisalign aligners will be printed and shipped to our practice.



Step 3: Wearing aligners

You are required to wear your aligners for 20 to 22 hours daily. Aligners are NOT worn during meals and NOT worn for flossing/brushing. Compliance with aligner wear is crucial for treatment success.



 At your first visit, you will have customised attachments glued on to your teeth, called attachments. These attachments help by improving the grip and fit of the aligners onto your teeth to help your teeth to move.



You will need to change your aligners as directed by your dentist. Each set of aligners will gently and gradually shift your teeth into place, until your ideal smile is achieved.



You will be monitored during the Invisalign treatment process. Monitoring visits take place every 6-8 weeks.



Step 4: Completing treatment


Once you have reached the end of your Invisalign treatment, the attachments are removed from your teeth and a set of removable retainers will be made.



Retainers help prevent relapse (where the teeth shift after alignment is complete). Relapse can occur very soon after stopping treatment or occur many years later.

Visits to the dentist for reviewAligner trays are changed every 2 weeks. Monitoring visits every 6-8 weeksAdjustment visits every 3-4 weeks
