FAS Aligner System®
FAS Aligner System® is a modern, invisible orthodontic system based on custom-made clear aligners, designed to correct the position of the teeth in a discreet, comfortable and predictable way. Unlike traditional braces, FAS® aligners are virtually invisible and can be removed whilst eating or brushing your teeth.
The FAS Aligner System® stands out for its advanced approach to orthodontic treatment, which focuses not only on the aesthetic alignment of the teeth, but also on achieving a correct and stable functional occlusion in the long term.
How do FAS® aligners work?
Treatment with the FAS® aligner system uses a series of digitally-designed clear aligners, which apply controlled pressure to gradually move the teeth into the correct position.
Each set of aligners is customised according to the patient’s dental anatomy and the orthodontic treatment plan established by the dentist. The aligners are changed progressively, with each stage designed to achieve precise tooth movements and balance the bite.
One of the innovative features of the FAS® system is the integration of vertical control into the treatment plan. This concept enables the achievement of correct occlusion with fewer aligners and fewer intermediate adjustments.
The benefits of FAS Aligner System®
Treatment with FAS Aligner System® shares similarities with other types of invisible braces, but is distinguished by its ability to functionally correct dental occlusion.
Understated aesthetics
FAS® aligners are transparent and almost invisible when worn. They are an ideal solution for adults and teenagers who want discreet orthodontic treatment that does not affect the appearance of their smile.
Superior comfort
The aligners are made from innovative materials and have smooth edges, designed for optimum comfort. There are no metal brackets or wires that could cause irritation.
Personalised digital treatment
Each treatment is planned digitally, which ensures a high degree of predictability in the results and allows for precise monitoring of the teeth’s progress.
Fewer alignments and fewer adjustments
Thanks to its advanced biomechanical control, the FAS® system can reduce the number of aligners required and the frequency of readjustments in certain orthodontic cases.
Improving occlusion and mastication
The FAS Aligner System® is designed not only to achieve aesthetic alignment of the teeth, but also to harmonise the relationship between the teeth and the temporomandibular joints. This can help to:
- improved chewing;
- the correct distribution of occlusal forces;
- reducing discomfort associated with bite problems;
- long-term functional stability.
Easy to maintain
Aligners can be removed for:
- meals;
- brushing;
- flossing;
- special occasions.
This makes oral hygiene much easier compared to fixed braces.
What dental problems can the FAS Aligner System® correct?
The FAS Aligner System® can treat a wide range of malocclusions and orthodontic problems, such as:
- crowded teeth;
- gaps between teeth;
- deep bite;
- open bite;
- crossbite;
- incorrect occlusion;
- relapses following previous orthodontic treatment.
Eligibility for treatment is determined following an orthodontic consultation and a digital scan.
Who is treatment with FAS Aligner System® suitable for?
FAS® aligner treatment is recommended for:
- adults who want invisible braces;
- teenagers concerned about their appearance;
- working professionals;
- people looking for a comfortable alternative to metal braces;
- patients who want digital and predictable orthodontic treatment.
How long does treatment with FAS® braces take?
The duration of treatment varies depending on the complexity of the orthodontic case. Generally, treatment with FAS® aligners can last from a few months to approximately 1–2 years.
Following the dentist’s recommendations and wearing the aligners for at least 20–22 hours a day directly affects the effectiveness and duration of treatment.

Am avut o experiență excelentă la DENT ESTET Aviatorilor 98 și îi recomand cu toată încrederea pe Dr. Alexandru Georgescu și Dr. Maria Ruse. Dr. Alexandru Georgescu mi-a realizat intervenția de sinus lift și inserarea implantului dentar. M-a impresionat prin profesionalism, punctualitate, precizia cu care lucrează și rapiditatea intervenției, fără a face niciun compromis în privința calității. Mi-a explicat fiecare etapă a tratamentului, iar pe tot parcursul m-am simțit în deplină siguranță. De asemenea, îi mulțumesc doamnei Dr. Maria Ruse, care mi-a reparat cu multă răbdare și atenție un molar de minte. Profesionalismul, grija pentru pacient și atenția la detalii au făcut ca rezultatul să fie unul excelent. Un gând de apreciere și pentru doamna Mari Grecu Pîrvan, asistenta medicală, pentru amabilitate, calm și sprijinul oferit la fiecare vizită. Se vede că formează o echipă extraordinară alături de Dr. Alexandru Georgescu. Felicitări întregii echipe DENT ESTET pentru profesionalism și pentru standardele înalte pe care le oferă. Recomand cu toată încrederea!

Mereu locul este curat, personalul primitor, nu esti fortat sau pus sub presiune cu privire la efectuarea unui tratament, ti se prezinta alternative. Multumesc domnisoarei dr.Lascău! Cred ca este al 4-lea sau al 3-lea an consecutiv de cand am decis ferm hotarat care este medicul potrivit pentru mine. Nu mai vin la dentist cu teama si acesta este cel mai mare avantaj pentru mine in calitate de pacient, deoarece imi este sporita complianta la tratamentele aplicate astfel.

My family and I have been patients of Dent Estet for many years, and this is the only clinic where we do our regular dental check-ups and treatments. I recently went in for a routine dental cleaning, which led to a discussion about replacing some of my old fillings with ceramic restorations. It turned out to be a more complex treatment than I initially expected, but I couldn’t be happier with the result. The quality of the work is outstanding, the entire team is professional, and throughout the treatment I always felt I was in very good hands. A special thanks to Dr. Horațiu Dobre for the excellent work and attention to detail. The treatment is certainly not inexpensive, but the quality, professionalism, and final result make it well worth the investment. Looking back, I would make exactly the same decision again. I can genuinely recommend Dent Estet to anyone looking for long-term, high-quality dental care.
