Key Differences Between Spark Aligners vs Invisalign for Clear Aligner Treatment

Clear aligners have transformed the world of orthodontics. More people than ever before have undergone orthodontic treatment thanks to clear aligner options. They have attracted people of all ages, including teenagers undergoing orthodontic treatment for the first time and young adults who avoided metal braces when they were younger. It also includes older patients who have previously undergone orthodontic treatment but wish to perfect their smile further. Clear aligners allow patients to transform their teeth without drawing unwanted attention to their mouth.

A Brief Outline of Invisalign and Spark

Since 1998 the most popular clear aligner treatment has been Invisalign. Invisalign has treated millions of patients across the world in the last two and a half decades and continues to be the most popular aligner of choice. This is because Align Technology, the company that designs and manufactures Invisalign aligners held the patent for clear aligners for almost two decades. In 2017, the patent expired, and since then other companies have also established themselves in designing and manufacturing clear aligners.

Ormco is a global leader in orthodontic products with over 60 years of experience. In 2021 Ormco received FDA approval for Spark aligners. Since then Spark aligners have already been used to treat thousands of patients across the world, beginning with Australia and New Zealand and then moving on to the USA.

Spark Aligners vs Invisalign

When considering Spark aligners vs Invisalign it should be noted that both aligners work in a similar way. They are designed to treat a range of orthodontic issues. This includes crooked or overlapping teeth, protruding teeth, overcrowded teeth and some types of bite disorders. Both options are discreet, comfortable and convenient, suited for a modern lifestyle. Although they work in a similar way there are also key differences in Spark aligners vs Invisalign.

Material Differences of Spark Aligners vs Invisalign

One of the key differences between Spark aligners vs Invisalign is the material with which they are manufactured. Invisalign is manufactured using SmartTrack aligner material. This is a multi-layer polymer that helps to control tooth movements and conform to the shape of teeth. It is the original clear aligner material and Align Technology holds the patent for it.

Spark aligners are made from TrueGen material which is patented to Ormco. The key difference between the two material types is that TrueGen is more transparent than SmartTrack. Although SmartTrack aligners are also clear, the exceptional clarity of TrueGen aligners provides an enhanced offering of discretion. When considering Spark aligners vs Invisalign, you may opt for the former if truly invisible orthodontic treatment is your top priority.

Another difference between the materials of Spark aligners vs Invisalign is that TrueGen is more stain-resistant than SmartTrack. With Invisalign it is recommended that you remove your aligners or at least use a straw when drinking tea, coffee, cola or wine, whereas Spark aligners can forego this warning as they have been designed to resist stains. While Invisalign aligners are still stain-resistant to a certain extent, discolouration has been a complaint amongst clients, prompting Ormco to develop Spark aligners with stain resistance in mind.

How Comfortable are Spark Aligners vs Invisalign?

Invisalign aligners have been used for more than two decades and are known to be comfortable and convenient. They can be taken out of the mouth and replaced with ease. However, since their introduction, it has been found that Spark aligners are just as comfortable, if not more. This may be due to a difference in the manufacturing process of Spark aligners vs Invisalign. Invisalign aligners are 3D printed while Spark aligners are hand-trimmed for a more refined finish. Although the difference is small it is still noteworthy and patients looking for greater comfort may wish to opt for Spark aligners.

Which is Best: Spark Aligners vs Invisalign?

Since both options are similar, your dentist can help you weigh up the benefits of Spark aligners vs Invisalign. Invisalign has been used for the last 25 years and has helped treat millions of patients worldwide. Spark aligners have become popular very quickly and have been subject to much research and development before being introduced to the public. If you are looking to improve the alignment of your teeth for either cosmetic purposes or dental health issues, speak to your dentist today and find out which aligners are most suitable for you.
