What are the advantages of invisible orthodontics?
Invisible orthodontics, also known as transparent orthodontics or clear aligners, offers several advantages compared to other methods of orthodontic treatment.

Innovation
Aesthetics and Comfort
Transparent and smooth aligners that offer discreet dental correction and reduce discomfort.
Hygiene and Practicality
Removable to facilitate cleaning and eating, simplifying the oral hygiene routine.
Optimized Visits
Less frequent appointments needed with the orthodontist, with follow-up at home.
Unchanged Lifestyle
Allows continuing with daily activities without interference in speech or dietary restrictions.
It is important to note that invisible orthodontics may not be suitable for all cases of dental malocclusion. The choice of the appropriate treatment method will depend on the evaluation and recommendation of the orthodontist, taking into account the complexity of the case and the individual needs of the patient.
What are the brands of invisible orthodontics?
There are several prominent brands in the invisible orthodontics market, each with its own characteristics and advantages.
Main brands available
The most recognized brands in the invisible orthodontics market:
- Invisalign: Recognized and pioneer with custom clear aligners to correct dental alignment.
- Spark: Introduced in 2020, it has received excellent reviews for its innovations and effectiveness in invisible orthodontics.
- ClearCorrect: Another leading brand that provides a similar alternative to Invisalign with global reach.
- SureSmile: Combines 3D imaging technology with clear aligners for a more precise and efficient approach.
- Smartee System: With the advantages of Invisalign and Spark, but even more effective due to high technology, and with ultra-transparent high-end material that provides more aesthetics and effectiveness in treatment.
Differences between Spark and Invisalign system?
Spark presents several technological improvements compared to Invisalign:
- Greater retentive force: Spark provides superior retention force, which can result in shorter treatments and the ability to treat more complex cases.
- Greater transparency: Unlike Invisalign aligners, Spark has introduced TruGEN™ material in 2021, offering greater transparency and free of BPA, mercury, latex, and phthalates.
- Polished edges: Spark stands out for a more refined polish compared to Invisalign, which can contribute to a more comfortable experience for the user.
- Polymer fit to the tooth: Spark ensures closer contact between the aligner and the tooth, allowing for more effective movement at more points on the dental surface.
Invisible aligners for cases of different complexity
Both Invisalign and Spark offer options for different levels:
- Invisalign: Offers solutions such as Invisalign i7 and Lite for simple cases, and Comprehensive for more complex situations such as severe crowding or malocclusions.
- Spark: Provides a range that includes Spark 10 for simple cases, Spark 20 for intermediate ones, and Spark Advanced for the most complex.
- Software technology: With Invisalign, primarily the dental crown is visualized. Spark software allows integrating the complete root anatomy for more detailed planning and preventing side effects such as gingival recessions. Spark also offers the option to position attachments on the inner face of teeth and add posterior bite ramps to aesthetically improve results.
In conclusion, while Invisalign provides outstanding results, Spark stands out for its clarity, superior polish, and more comprehensive planning that considers the root of the teeth to prevent possible complications. Finally, the Smartee invisible orthodontic system is presented as a state-of-the-art innovation, combining the qualities of previous systems and improving them to achieve ideal results. The selection of the appropriate brand should consider individual characteristics, advantages, and orthodontist recommendations.

What factors influence the cost of invisible orthodontics?
The final price varies considerably from one patient to another. These are the main factors that the orthodontist evaluates at the initial consultation.

Case complexity
Mild crowding or a small gap requires fewer aligners (Lite / Spark 10–20) than a severe malocclusion requiring Comprehensive / Spark Advanced treatment. Greater complexity means more aligners and longer treatment time.
System and brand chosen
Invisalign, Spark and Smartee have different licensing structures. Within each brand, Lite plans are more affordable than Comprehensive or Advanced. The clinic can recommend the most suitable option for your case.
Number of arches treated
Correcting only one arch (upper or lower) is usually less expensive than treating both simultaneously. In many cases treating both arches at once is the most effective option.
Need for extractions or prior treatments
If the treatment plan requires dental extractions, periodontal treatment or fillings before orthodontics, these procedures have an additional cost and must be planned in advance.
Clinic experience and accreditation
Clinics with orthodontists directly certified by the brands (Invisalign Preferred, Spark Certified) have greater training and access to the most advanced planning systems, which may be reflected in the price but also in the quality of the outcome.
The only way to get an exact price is through a personalised assessment. At Clínica ENIQ we offer a no-obligation quote after the initial examination.

Yes, in certain cases. Clear aligners can be used in children as an alternative to traditional removable appliances, with the advantages of aesthetics, comfort and being removable, but not every case is suitable: an individual assessment by the orthodontist is needed. As with adults, the result depends on wearing the aligners 20-22 hours a day. In children and teenagers treatment can be faster, because their bones and teeth are still developing.
The price of invisible orthodontics in Madrid varies according to the system and case complexity. As a reference, Invisalign Lite (simple cases) starts from €3,100 and Invisalign Comprehensive (moderate or complex malocclusions) can reach up to €5,600. Spark and Smartee have similar ranges.

Invisible orthodontics is suitable for many cases of dental malocclusion, but not all. It is especially effective for mild to moderate crowding, spaces between teeth, overbite, underbite and crossbite. However, very complex cases of severe malocclusion may require traditional brackets. The success of treatment also depends greatly on the patient's discipline to wear the aligners for the recommended time (20-22 hours a day). Your orthodontist will evaluate your specific case during the initial consultation.
Duration varies according to case complexity. For mild or moderate cases (Invisalign Lite / Spark 10–20) treatment usually ranges from 6 to 12 months. Comprehensive treatments for more complex cases can last between 12 and 24 months. Your orthodontist will determine the exact duration at the initial assessment.
Orthodontics with clear aligners is usually the treatment that causes the least discomfort. It is considered a generally painless technique in its placement. It is normal to feel some pressure during the first days after changing to a new set of aligners, indicating they are working correctly. This discomfort usually disappears within one or two days and most patients describe it as very tolerable.
It depends on individual needs. Invisible orthodontics offers aesthetic and comfort advantages: it is virtually imperceptible, removable and does not restrict eating. Traditional brackets can be more effective for very complex cases and usually have a lower cost. Your orthodontist will evaluate your malocclusion, lifestyle and budget to recommend the most appropriate option. Both methods are effective when applied to the right case.
Yes. Some very specific tooth movements, severe malocclusion cases or patients with active periodontal disease may not be ideal candidates. Success also depends greatly on the patient's consistency (wearing aligners 20-22 hours a day). The initial assessment will determine whether you are a good candidate and, if not, which alternative is most appropriate.
With clear aligners the frequency of visits is lower than with traditional brackets. Reviews are typically held every 6-8 weeks to monitor progress, deliver new aligner sets and make adjustments if necessary. The total number of visits depends on the duration of treatment.

At Clínica ENIQ we work with Invisalign, Spark and the Smartee system. Each has specific advantages: Invisalign is the pioneer and most recognised brand; Spark stands out for its TruGEN™ material with greater transparency and retentive force; Smartee combines the best of both systems with high-end materials. Your orthodontist will recommend the most suitable option for your case and budget.
In the vast majority of cases invisible orthodontics is practically unnoticeable. The aligners are transparent and fit closely to the teeth. You may notice a slight lisp when speaking during the first few days, which usually disappears within a few days of adaptation. Attachments (small composite buttons) match the colour of the tooth and are difficult to notice at a normal conversational distance.
