What are the contraindications for getting Invisalign, Zenyum, Clear Smile etc.?

Doctor's Answers 1

Clear aligner as a treatment alternative to traditional braces is indeed a growing market, thanks to the advances in 3D technology. It is no wonder that in recent times, there are quite a few clear aligner companies in the market. Invisalign, Zenyum and Clear Smile are all laboratories that produce clear aligners which are custom made appliances that gradually push teeth to effect the same result as braces except that these braces are less conspicuous, more comfortable and removable.

However, Zenyum and Clear Smile laboratories are only able to produce aligners that correct front teeth alignment and cannot manage complex treatments that require extractions.

In my personal opinion, Invisalign is able to manage simple to complex malocclusions, and may sometimes be a better option than traditional braces in cases such as an anterior open bite or patients who are unable to have metal braces due to medical reasons.

In my opinion, these are some clinical situations where I feel that clear aligners may not be as suitable and these include:

  1. Impacted teeth that require orthodontic traction
  2. Deep bite cases requiring extraction
  3. Patients who feel they will not be so compliant as they need to frequently snack and need to take lots of small meals. Clear aligner treatment is very dependent on patient compliance, you need to wear the aligners for 20-22 hours a day in order for the appliance to be effective. Hence if you feel you are not able to commit to this then it may not be the right appliance for you.
  4. Large spaces that require the back teeth to move forward by more than 3mm (e.g molar extraction spaces)

In deciding if clear aligner treatment is suitable for you, it is best to consult your dentist/orthodontist who will be able to examine your treatment needs and recommend the best appliance tailored to your individual needs.

What's the difference between Invisalign and Zenyum?

Zenyum is a Singapore based company that has been operational in Singapore since September 2018, whereas Invisalign was the first aligner company to be established in Singapore many years back and is the most established aligner company in the market. For other clear aligners systems or braces in general, orthodontic treatment starts with a physical consultation with an orthodontist or dentist of your choosing, and they will advise you on what system is suitable for you and the ideal treatment plan for your case after a clinical examination with the assistance of X-rays and other records.

How do clear aligner brands such as Zenyum, ClearSmile and MBrace compare against Invisalign?

As you have said, Zenyum is a very new clear aligner company. There is very little background information on the official website regarding the technology used for their treatment planning and aligner manufacturing. Zenyum appears to be a collaboration between local orthodontists and tech entrepreneurs. At the moment, there is no verifiable track record that is available for the public to see. I cannot tell you what software they are using for treatment planning.
