May 29, 2026Clear aligners have become the choice for those who prioritise discretion when deciding to achieve a perfectly aligned smile. Spark™ aligners are one of the most advanced orthodontic solutions, used to straighten teeth in a discreet, controlled and predictable manner.
Spark™ is a clear aligner system used to correct tooth alignment. The treatment is planned digitally; the aligners are worn for 20–22 hours a day, and the cost at DENT ESTET clinics starts from €1,800, depending on the complexity of the case.
In this article, Dr. Ștefan Ciobanu, a specialist in Orthodontics and Dentofacial Orthopaedics, explains the advantages of Spark™ aligners compared to other types of clear aligners, outlines the stages of treatment, and provides information on the cost of Spark™ aligners.
What are Spark™ braces?
The Spark™ dental aligner is a modern orthodontic system based on clear aligners, which stands out in the dental aligner market due to the material from which the aligners are made.
TruGEN™ material was developed by the American company Ormco to offer a combination of aesthetic clarity and biomechanical efficiency.
TruGEN™ is optimised to provide:
- better contact between the aligner and the tooth;
- sustained force over a longer period;
- clearer, more comfortable and more stain-resistant aligners.
According to research carried out by Ormco, 98 per cent of dentists agree that the contact surface between the aligner and the tooth is a key factor in determining the predictability of tooth movement, and the TruGEN™ material is designed precisely to maximise this contact.
The advantages of Spark™ aligners over other clear aligners
Beyond its clinical effectiveness, the Spark™ solution offers a range of practical benefits that radically transform the experience of wearing braces.
| Superior aesthetics | Thanks to TruGEN™, the Spark™ aligner is much more transparent than other aligners. |
| Enhanced stain resistance | The plastic material is specially designed for clarity and superior stain resistance. |
| More efficient tooth movement | A smoother surface increases the contact points between the tooth and the aligner. |
| Enhanced comfort | Hand-finished edges ensure comfort without irritating the gums. |
| Digital planning and predictability | You know from the very first consultation how long the treatment will take and what your teeth will look like at the end. |
| Enhanced biocompatibility | The aligners contain no BPA, mercury, latex or phthalates. |
How does treatment with Spark™ aligners work?
Spark™ treatment strikes the perfect balance between the expertise of orthodontists and the most advanced digital technologies. Here is the complete, step-by-step process:
Consultation and 3D digital scanning
The orthodontist carries out an assessment of dental health and bite (occlusion).
Using an intraoral scan, a digital replica of the teeth is created, which forms the basis for an accurate treatment plan.
Digital Planning
The Spark Approver™ software offers flexibility in accessing the platform and comprehensive treatment solutions.
Cloud-based access facilitates orthodontic diagnosis and treatment planning.
Personalisation through innovation
The custom aligners are produced based on the data obtained.
Each set of aligners corresponds to a specific stage in the treatment plan.
The 22-hour rule
For best results, the aligners should be worn daily for 20–22 hours, and should only be removed at mealtimes and to clean your teeth.
On the orthodontist’s advice, the set of aligners is usually changed every 7–14 days.
Constant monitoring
Visits to the clinic focus on monitoring progress in straightening the teeth.
Because the aligners can be easily removed, appointments are shorter and less frequent than with traditional braces.
Retention stage
Once the desired alignment has been achieved, the retention phase begins: wearing special, discreet and comfortable retainers that prevent the teeth from returning to their original position.
In this way, the results achieved are maintained in the long term.
“In my opinion, Spark™ aligners are one of the most balanced orthodontic systems available today. Digital planning using Spark Approver™ allows me to control every stage of tooth movement with a level of precision that traditional braces cannot match. For my patients – both adults and teenagers – Spark means a discreet, comfortable treatment with predictable results right from the very first consultation.” – Dr. Ștefan Ciobanu, specialist in orthodontics and dentofacial orthopaedics
What orthodontic conditions does Spark™ treat?
Treatment with Spark™ aligners is a versatile solution, designed to address a wide range of dental irregularities, from the simplest to those of a high degree of complexity:
- Dental crowding – Spark™ uses controlled forces to create the necessary space and reposition the teeth.
- Diastema – The aligners are extremely effective at closing excessive gaps between teeth.
- Underbite – The aligners help to correct a situation where the lower teeth are positioned in front of the upper teeth, contributing to normal functioning of the temporomandibular joint and preventing premature tooth wear.
- Deep bite (Overbite) – Using the Spark Approver™ digital planning system, the orthodontist can precisely control the movement of the teeth up or down to achieve correct vertical overlap and a balanced smile.
- Crossbite – The technology behind these aligners allows for the expansion of the dental arches and their correct alignment, preventing tooth wear and facial asymmetries.
- Open bite – Aligners are often preferred in these cases due to their ability to control vertical movements and restore masticatory and phonetic function
How much does treatment with Spark™ aligners cost?
The cost of Spark™ treatment is not standard, as it reflects each patient’s individual anatomical characteristics and the complexity of their case. At DENT ESTET clinics, the cost of Spark™ aligner treatment starts at €1,800, but the final price is determined by the personalised treatment plan, which takes into account the number of aligners required.
The exact cost of Spark™ treatment is determined only following an in-depth consultation and a thorough analysis of the orthodontic diagnosis.
Medical expertise: a key factor in the success of treatment
Although Spark™ technology offers advanced tools, the success of the treatment depends directly on the diagnosis and treatment plan established by the specialist in Orthodontics and Dentofacial Orthopaedics.
Each case is assessed on an individual basis: whether it involves a minor aesthetic correction or a complex functional problem, the orthodontist will determine whether the Spark™ system is the right solution for each patient’s anatomy and treatment goals.
The first step is a consultation with a specialist orthodontist, who will assess your situation and recommend the optimal treatment option.
