What Are Spark Aligners Made Of

Spark Clear Aligners are manufactured using TruGEN™ material, which is designed to offer comfort, clarity, and a lower likelihood of staining. The material is engineered to facilitate more efficient and effective tooth movement. TruGEN™ aims to provide sustained force retention and improved contact with the tooth surface. Spark Aligners are free from BPA, mercury, latex, and phthalates.

The TruGEN™ material comes in two varieties: TruGEN and TruGEN XR™, with primary differences in their flexibility. TruGEN XR is more rigid, indicated by a higher flexural modulus value, while TruGEN is comparatively more flexible. Both TruGEN and TruGEN XR maintain a uniform material thickness of .75mm (.030”). This diversity in material properties allows for tailored treatment approaches depending on the specific needs of the patient’s orthodontic case.

How Are Spark Aligners Different?

Spark Aligners distinguish themselves in the market through several key features. Firstly, they are more clear, nearly invisible, and reportedly less noticeable than competitors like Invisalign. The use of TruGEN™ and TruGEN™ XR materials in their construction is said to result in aligners with scalloped, smooth edges, claiming to offer better comfort compared to Invisalign.

Additionally, Spark Aligners are designed to be more resistant to staining from common beverages such as coffee, hot chocolate, or tea, compared to Invisalign. 

Furthermore, Spark Aligners are specifically engineered for efficient tooth movement. The TruGEN™ and TruGEN™ XR materials are claimed to provide more advanced and sustained force retention and improved contact with the tooth surface.

Who Is a Candidate for Spark Aligners?

Spark clear aligners are available for adults, teens, and children, provided they have all their permanent teeth, including second molars.

Treatable Cases

Spark Clear Aligners can be used to treat various malocclusions, including:

  • Open Bite: A condition with a vertical gap between the upper and lower teeth.
  • Deep Bite: Characterized by an excessive overlap of the upper teeth over the lower teeth.
  • Overbite (Class II): A condition where the upper teeth protrude significantly over the lower teeth.
  • Underbite (Class III): Occurs when the lower teeth extend forward beyond the upper teeth.
  • Crossbite: A misalignment where the upper and lower teeth do not align properly side to side.
  • Crowding: A misalignment that occurs when there’s insufficient space in the mouth for all the teeth to fit normally.
  • Spacing: Involves gaps or spaces between the teeth.

Patients who have severe periodontal disease are not suitable for Spark aligner treatment until their periodontal condition is effectively managed and under control.

Worth Knowing

In 2021, the Spark Clear Aligner System was granted FDA clearance for use in younger patients.

Types of Spark Aligners

Spark™ Aligners provide a trio of treatment options designed to accommodate various teeth straightening needs. These options include Spark™ 10, Spark™ 20, and Spark Advanced, each tailored to meet specific orthodontic requirements. The choice among these systems is determined based on the individual treatment needs and personal smile objectives of the patient, as assessed during the initial consultation. Spark does not offer night aligners; all their systems are designed for continuous wear.

Spark Advanced

The Spark Advanced aligner system is designed for the comprehensive treatment of complex malocclusions. It offers an unlimited number of aligners and allows for unlimited refinements to ensure thorough and precise treatment outcomes. This system can be used for either double or single-arch treatments, depending on the patient’s needs. 

For effective results, patients are required to wear the aligners for 22 hours per day. Each set of aligners in the Spark Advanced series is typically worn for one week before progressing to the next set in the treatment plan.

What The Process Looks Like

Spark aligners, unlike some other aligner brands, are provided through a network of Spark-affiliated orthodontists, emphasizing a doctor-directed approach to orthodontic treatment. 

Initial Consultation: The process of wearing Spark aligners involves a series of steps, beginning with an initial consultation with an orthodontist. This consultation includes an examination of the patient’s teeth and an introduction to what the Spark system can offer.

Digital Scan and Treatment Plan: Following the consultation, the orthodontist takes a digital scan of the patient’s smile. This scan is used to create a personalized treatment plan using Approver™ – Spark’s proprietary 3D software. This software generates a simulation of the patient’s teeth, including root positions, based on a library of past cases.

Custom Manufacturing of Aligners: The orthodontist uses the treatment plan to manufacture custom aligners for the patient. Depending on the treatment’s complexity, they may add attachments to certain teeth. These attachments help move the teeth in sync with the aligners.

Treatment Commencement: Treatment starts when the patient visits their orthodontist to pick up the first set of aligners. During this visit, the orthodontist checks the aligners’ fit, discusses the treatment process and schedule, and answers any questions. The patient then schedules to pick up subsequent sets of aligners.

Regular Wear and Schedule: Patients typically receive a new set of aligners every one to two weeks as part of their personalized treatment plan. They should wear their Spark aligners for 22 hours a day, removing them only for eating, drinking, or brushing.

Regular Orthodontist Visits: The treatment requires regular orthodontist visits, every 4 to 10 weeks. During these visits, the orthodontist monitors progress and makes any necessary adjustments.

Post-Treatment Retention: After completing the treatment with Spark aligners, the final stage involves wearing retainers. This is crucial for maintaining the alignment of the teeth and ensuring the long-term stability of the treatment results.

Worth Knowing

Worth Knowing

According to the article published in The Angle Orthodontist, aligner therapy requires significantly fewer visits to an orthodontist and a shorter treatment time than braces.

How Long Does Treatment Take?

The length of treatment with Spark aligners depends on the individual’s orthodontic requirements. While it can range broadly from 12 to 36 months, patients with mild malocclusions usually complete their treatment within a shorter timeframe, typically between 12 to 15 months.

How Much Do Spark Aligners Cost?

The cost of Spark clear aligners varies and is determined by the individual Spark provider, based on factors such as the complexity of the case and the length of the treatment. The price range typically falls between $3,500 and $8,000, which is comparable to Invisalign. 

Included in your Spark treatment are services like a 3D scan during your initial consultation with a Spark orthodontist, custom-designed aligners, and ongoing virtual or in-person monitoring and consultations with your orthodontist throughout the treatment.

Can Spark Aligners Be Covered by Insurance?

Spark Aligners can potentially be covered by insurance if you have dental or orthodontic coverage. Coverage for a portion or the full cost of treatment, especially when consulting a specialist orthodontist, is likely under many insurance plans. However, as policies and coverage vary, it’s important to discuss financing options directly with your dental office.

Additionally, you can use Pre-Tax Dollars from a Health Savings Account (HSA) or a Flexible Spending Account (FSA) to pay for clear aligner treatment. These accounts allow you to set aside money on a pre-tax basis for qualified medical expenses, which may include orthodontic treatments like Spark Aligners.

Furthermore, many orthodontists offer interest-free payment plans, allowing for the spreading out of payments over time to make treatment more affordable. For those facing financial hardship, programs like Smile for a Lifetime Foundation and the American Association of Orthodontists Donated Orthodontic Services Program offer deeply discounted or free treatment for eligible individuals, especially children from low-income families.

Does Spark Really Work? Customer Reviews

Customer feedback on Spark aligners is predominantly positive. Users commend their invisibility and effectiveness, with many noting their superiority in thinness and clarity compared to similar products like Invisalign. While some initial discomfort is reported, it tends to decrease over time. The aligners are also praised for their durability and resistance to staining. However, a few customers have experienced incomplete results, necessitating additional orthodontic treatments.


Spark Clear Aligners emerge as a strong competitor in the clear aligner market. Backed by decades of orthodontic experience and utilizing advanced TruGENTM material, Spark offers comparable results to leading brands like Invisalign at an equivalent price point. Though minor limitations exist, the aligners effectively treat a wide range of malocclusions in adults and teens.

With benefits like improved comfort, stain resistance, tooth control, and nearly invisible aesthetics, Spark Aligners present an appealing choice for those seeking affordable, doctor-directed clear aligner therapy.
