Last updated 29 April, 2022

Clear aligners are comfortable, easy to use, and offer a better alternative to conventional braces. We look at the similarities and differences between the top clear aligners.

Many people benefit from teeth alignment and straightening. Whether as an adult or a teenager, a perfect smile is a huge asset for your confidence. The good news is that there are several options for invisible braces and clear aligners you can use to align and straighten your teeth.

You have probably come across one or a few of the aligners in this review, and are wondering which method suits you. We’ll compare the various invisible braces and clear aligner options so you can choose the ideal method for you.

What are "clear braces"?

Clear braces are made of medical-grade plastic and work by exerting pressure on teeth, straightening and aligning them over time. Unlike traditional metal braces, they are easily removable and invisible.

The invisible aligners use 3D scanning technology and specialised software to curate the perfect smile and map out treatment. The dentist will digitally scan your teeth to produce aligners that suit your condition. You will have to wear these custom-made aligners for a period of time to straighten your teeth.

To help you decide which of the aligners suits you best, we will review each in terms of price, comfort when wearing them, and the treatment process.

Invisalign

Align Technology Inc.'s Invisalign, a pioneering teeth alignment product, has served over 9 million perfect smiles. It uses 3D visualisation and computer-aided design software to create custom-made aligners to suit individual needs. Let us look at the benefits of Invisalign in terms of comfort, treatment process, price, and pros and cons.

Comfort

Invisalign clear braces are smooth with no sharp edges, making them extremely comfortable to wear. When wearing them, you will not struggle while you chew or eat. They are also easy to attach and detach.

Invisalign treatment process

The treatment process for Invisalign is fast. The patient will have to replace the aligners every week and visit the dentist every 6 to 8 weeks. They treat severe overbite and underbite, overcrowding, crooked and protruding teeth. Depending on the severity of the issue, you can begin to see results in around six months. Here is the Invisalign treatment process:

  • You will need to visit the dentist for an assessment.
  • The dentist will take a digital scan that will be used to create a custom treatment plan.
  • Custom aligners are made and sent to the dentist for fixing.
  • Regular checks to monitor progress.
  • Wearing of refiners after the treatment process.

Price of Invisalign

The price of Invisalign is high as compared to other clear aligners. This is because you get the supervision and care of a licensed dentist. The cost of Invisalign treatment in Singapore varies from one clinic to another. However, the average cost of the treatment is $4,500 to $9,000.

Advantages of Invisalign

  • Invisalign is supported by more than 20 years of research, ensuring its effectiveness.
  • Shorter treatment time.
  • The predictability rate of teeth straightening exceeds 75%.
  • High levels of comfort due to the smart track material.
  • Aligners have a smart force attachment that applies the necessary force in the right direction.

Zenyum is a relatively new teeth-aligner brand in Singapore. It’s more affordable than Invisalign and works on mild and moderate cases. It has two treatment plans:

  • ZenyumClear is suitable for mild to moderate cases involving the movement of upper and bottom eight teeth.
  • ZenyumClear Plus is used for complex cases involving movement of all teeth.

Comfort

Zenyum is comfortable to wear. However, you may experience minimal pain as the tray applies pressure to your teeth to shift them. It’s easy to take off the braces during meal times, so you don’t have to worry about food getting stuck.

Zenyum treatment process

The treatment process is straightforward. All you need to do is fill out the online survey form and then upload a photo. They will send the photo to a specialist. You will be advised which clinic you should visit for a 3D scan and an X-ray.

Which brand of invisible braces is right for me?

When choosing clear alignment braces, there are several factors that you should consider. Here are some things that you should look out for when selecting invisible braces in Singapore.

Cost of the clear braces

Clear aligners provide long-term benefits for your overall and oral health. You must consider your budget and select one that is affordable and suits your needs. Review your needs with your dentist and choose the brand that works for you.

The cost of aligners will depend on the complexity of your case, dentist’s fees, and the cost of customising the aligners.

Treatment time

Your teeth's current state and health will determine how long it takes to get the perfect smile. The aligners you choose also determine how long it takes for your teeth to shift into alignment. Simple cases will need fewer aligners and take less time. Review your case with an expert, and he/she will guide you on the most appropriate aligners that take the least amount of time.

Maintenance of the aligners

You may need to soak the aligners at least once per day to keep them clean and kill bacteria. You need to discuss the maintenance procedure for the aligners you choose with the dentist. 

Complexity of your issue

The type of aligner you choose can depend on the complexity of your issue. Brands like Zenyum may not cover very complex cases. On the other hand, Invisalign will treat even complex cases.

Conclusion: Which one of the clear aligners is the best?

At the end of the day, the best aligner suits your needs and is within your budget. You need to assess the complexity of your teeth issues and select the aligners that work for you. To ensure that you have the right aligners, you can start off by visiting your dentist for an assessment.
