Modern orthodontics offers revolutionary solutions for straightening teeth that are changing the way we view orthodontic treatment as a whole.
At DentaTime Dental Clinic, we are proud to offer our patients the most advanced technologies for achieving a perfect smile. The Invisalign system represents the pinnacle of innovative technology for treating misaligned teeth.
What is Invisalign?
Invisalign is one of the most modern and preferred aesthetic systems for treating misaligned teeth in modern orthodontics. It is carried out using a set of completely transparent, removable aligners, which are changed every 1–2 weeks.
Each set of aligners is custom-made for each patient using modern 3D technology to analyse dental impressions.
Invisalign aligners are made from a unique, high-quality material called SmartTrack, which helps shape the smile with maximum treatment precision to achieve the desired aesthetics, comfort and predictable results.
Invisalign is the world’s leading aligner treatment company, with over 20 years of experience, continuous innovation, improvements and research.
What are the advantages?
The specific advantages of Invisalign lie in its innovative approach to orthodontic treatment. This system offers many benefits compared to traditional braces. An experienced dentist will explain all the options to you.
The main advantages are:
- Teeth straightening is virtually unnoticeable and the aligners are almost invisible.
- Patients can track the progress of their treatment at every stage and feel satisfied with the changes.
- There are no dietary restrictions, and you do not need to give up your favourite foods.
- There are no restrictions on wearing them whilst playing sport.
- Maintaining oral hygiene with braces is a problem, whereas with aligners it is made as easy as possible – teeth are cleaned as usual because the aligners are removed.
These comfortable aligners offer undeniable advantages over conventional methods. The noticeable comfort of aligners makes them suitable for various age groups, including active people.
How does treatment with them work?

The treatment planning itself takes place in 3 main steps following a visit to our orthodontist at the Dentatime clinic and draws on the expertise of a broad international team.
Step 1
Once the orthodontist has carried out a medical assessment and confirmed that Invisalign treatment is suitable for you, photographs and X-rays will be taken and dental impressions will be made.
The impressions are scanned in Amsterdam, the Netherlands, to be transformed into a virtual model. This data will be used to create a 3D digital treatment plan tailored to your needs.
A week later, we will receive a video simulation (ClinCheck) of your treatment, and you will be able to track the movement of your teeth and the final result. This digital simulation is based on data from over 5 million treated patients.
Step 2
The aligners are manufactured in Mexico and delivered to us at the Dentatime clinic. As soon as we receive them, we will provide you with the first set of aligners, which you should wear for 22 hours a day and change at home every 1–2 weeks on average.

Step 3
This is followed by visits to our orthodontist approximately every 6–8 weeks to monitor and assess the treatment results and receive the next set of aligners. The specific duration of treatment varies depending on the complexity of each case.
Once the treatment plan is complete, retainers will be required to maintain your new smile, a standard procedure following orthodontic treatment. Retainers are worn for an extended period of time, typically for life.
Comparison of the Invisalign system with other treatment methods
Making the right choice between the various orthodontic methods requires a detailed comparison. Ceramic braces, sapphire braces, self-ligating braces and lingual braces are alternatives, each with their own specific characteristics.
The table below compares Invisalign with other options for orthodontic treatment.

Who is it suitable for?
The Invisalign system is effective for correcting a wide range of misalignments.
Misaligned and crowded teeth
When there is not enough space in the jaw for all the teeth to align properly, they may be rotated, overlap, and sometimes even protrude significantly forwards or inwards.
Crowded teeth make it difficult to clean them properly with a toothbrush and floss, making it easier for unwanted plaque to build up and tartar to form. These are problems that are a major cause of tooth decay and gum and periodontal disease, which can lead to tooth loss in the future.
Deep bite
When the upper front teeth cover more than a third of the lower teeth when the teeth are clenched, or the upper teeth completely cover the lower teeth, this is known as a deep bite. This is a problem that can lead to excessive and premature wear of the teeth.
This, in turn, can cause pain in the lower jaw joint; in some people, the bite is so deep that the lower front teeth press against the gum/palate behind the upper teeth, causing trauma.
Presence of a crossbite (reverse bite) in the front teeth
This is observed in cases where, when the mouth is closed (teeth clenched), the lower front teeth are positioned in front of the upper ones. This can lead to problems with chewing and speech, and can also cause faster and abnormal wear of the teeth. Receding gums and exposure of the roots of the front teeth may also occur.
Open bite
When the lower and upper teeth do not touch when the mouth is closed and a gap remains between them. This makes it difficult to chew food; such patients are prone to gum inflammation, multiple cavities, tooth loss and premature wear of the temporomandibular joint.
Gaps between the teeth
When there is more space between two adjacent teeth, these are called diastemas or gaps and can lead to the formation of pockets between the teeth and the gums, due to difficulty in cleaning between the teeth. This can cause gum inflammation, followed by loosening and loss of teeth.

Frequently asked questions
How much does the full course of Invisalign treatment cost?
The cost of Invisalign treatment is determined by the severity of the problem and the number of aligners required for the correction. The exact number of aligners is calculated when the virtual treatment plan is drawn up. The cost ranges from 5,000 to 9,000 BGN.
How many hours a day should the aligners be worn, and how are they cleaned?
It is important to wear them for 20–22 hours a day for the best results. It is recommended that they be brushed carefully every evening with a non-abrasive (non-whitening) toothpaste and rinsed to keep them clean and fresh.
Is there any discomfort when wearing aligners?
At first, it is normal to feel slight tension or discomfort, which subsides during the first few days of wearing them.
