What Is Invisalign?

Invisalign clear aligners are a type of orthodontic treatment available in Singapore designed to straighten teeth and fix a variety of orthodontic misalignment issues using a series of customised clear plastic aligners — offering a modern alternative to traditional metal braces.

Invisalign clear aligners are developed with a patented multi-layer thermoplastic material called SmartTrack, engineered specifically to provide a comfortable yet effective experience by exerting a gentle corrective pressure while ensuring a tailored fit.

Invisalign aligners are transparent and close to invisible when worn, making them popular among people who seek more discreet orthodontic solutions compared to traditional metal braces that use brackets and wires. They are also removable, allowing you to take them out before eating, drinking, brushing, and flossing.

This makes Invisalign an ideal choice for those in Singapore looking to maintain their usual lifestyle without food restrictions and potential discomfort associated with traditional braces.

How Does Invisalign Work?

The Invisalign system starts with a thorough assessment by a dentist or orthodontist to understand your current oral condition, concerns and desired results. This consultation also helps your dentist or orthodontist assess your suitability for Invisalign.

A 3D model of your teeth is then created using a specialised software, allowing your dentist to craft a personalised treatment plan tailored to your needs, and to explain the improvements you can expect during the various stages of your treatment. This digital model is also used to physically produce a series of custom-made aligners designed to fit snugly and comfortably over your teeth.

Over time, with consistent use of the aligners, Invisalign gradually and gently shifts your teeth into the desired position with controlled force. Patients are advised to wear their Invisalign aligners for 20 to 22 hours a day.

Your progress is monitored every 6 - 8 weeks and you’ll be required to switch to a new set of aligners every 2 weeks, with each new set bringing your teeth closer to their final position. This is unlike conventional braces, where the orthodontist needs to manually adjust the wires and brackets.

Invisalign allows for consistent and gentle movement with each new aligner from the comfort of your home, minimising discomfort and the need for frequent clinic visits.

What Results Can I Expect?

Invisalign clear aligners deliver gradual and significant results, with many patients in Singapore seeing changes within a few months of starting treatment. The final outcome is typically a straighter and better-aligned smile that not only improves the teeth’s appearance, but also allows it to function more effectively. This, in turn, accords patients improved confidence and self-esteem, making Invisalign a life-changing experience for many.

The effectiveness of Invisalign depends on several factors, including the complexity of your dental issues and how closely you follow the treatment plan. Invisalign aligners must be worn consistently for the recommended 20 to 22 hours per day to achieve optimal results within the estimated timeline.

After treatment, most patients will need to wear a retainer at night to maintain their new smile. Teeth may shift back into their original position if retainers are not worn as directed, so it’s important to follow your orthodontist’s advice. With proper maintenance, you can expect your Invisalign results to last a lifetime.

How many treatment sessions are needed?

Treatment sessions

The number of treatment sessions and the overall length of Invisalign treatment largely depends on the individual. On average, Invisalign treatment takes about 12 to 18 months. However, some patients with minor alignment issues may complete treatment in as little as 6 months, while more complex cases can take up to two years. Each treatment plan is unique, and your orthodontist will give you an estimate based on your specific needs and goals.

Throughout the treatment, regular appointments with your dentist or orthodontist every six to eight weeks. These appointments allow them to monitor your progress and ensure the aligners fit properly, making adjustments when necessary to optimise your progress.

Number of aligners needed

Similarly, the number of aligners needed during treatment varies depending on the extent of your alignment issues. Some patients may require as few as 10 sets of aligners, while others may need up to 50. Each aligner is custom-designed to the structure of your teeth, allowing it to gradually and gently reposition your teeth into place. It’s important to keep to the schedule advised for ideal results.

Invisalign Aligners vs Traditional Braces in SIngapore

Transparent and discreet

Invisalign aligners are clear and practically invisible compared to traditional braces with visible wires and metal brackets that are more noticeable.

Easily removable

Made with SmartTrack flexible material, Invisalign aligners are easy to remove and put back on. Conventional braces, on the other hand, are fixed and cannot be removed, making it harder to consume certain foods.

Less pain and discomfort

SmartStage and SmartForce technologies allow for gradual, gentle, and effective teeth movement. Braces often cause irritation and pain due to constant pressure.

Less frequent trips to the dentist

Invisalign requires clinic visits only once every six to eight weeks, while braces typically require visits every three to six weeks.

Visual timelines

Invisalign provides a visual plan for each stage of treatment so you have a clearer understanding of your patient journey. Conversely, braces typically only offer an approximate timeline at the start of treatment.

Improved dental hygiene

Invisalign aligners are removable so you can brush and floss normally. Braces can impact oral hygiene, leading to plaque build-up around the metal brackets that can affect gum health long-term.

Your Questions Answered

Invisalign aligners should be worn for approximately 20 to 22 hours per day to achieve optimal results. The aligners should only be removed for eating, drinking anything other than water, brushing, and flossing. Inconsistent wear can result in delayed progress or ineffective treatment.

While Invisalign is generally less painful than traditional braces, patients may experience mild discomfort, especially when starting a new set of aligners. This discomfort is usually described as a feeling of pressure rather than sharp pain, and it typically subsides after a few days as the teeth adjust to the new aligners.

Invisalign aligners should be cleaned regularly to prevent the buildup of bacteria, plaque, or food particles. You can clean them using a soft toothbrush and lukewarm water, or use Invisalign cleaning crystals or solutions designed specifically for this purpose.

While Invisalign is highly effective in treating a variety of orthodontic issues, very severe cases of misalignment may still require traditional braces or other alternative forms of treatment. If your condition involves extreme crowding, significant jaw misalignment, or other complex conditions, your orthodontist may recommend a different approach.

The cost of Invisalign varies depending on the complexity of the case and the length of treatment. Generally, the cost ranges from SGD $4,000 to $9,000.
