Not just straight teeth – lasting function. For us, orthodontics is work on function, facial aesthetics and the balance of the entire chewing system. Every treatment is an individual plan – not a template.

A SMILE THAT CHANGES EVERYTHING

A smile is the first signal we send to the world – and it has a real impact on quality of life.

NOT JUST TEETH – THE WHOLE FACE
Orthodontics as a facial transformation.
Teeth are the centre of the face – and it is their alignment, proportions and visibility that determine whether a face appears harmonious, rested and attractive. That is why orthodontic analysis always begins with the face – not the teeth.
We assess facial proportions and symmetry – how the teeth fit the features, how much of the incisors shows at rest and when smiling, how the smile line follows the lower lip. Excessively flared incisors dominate the face – one of the more common problems, and one that can be corrected effectively.
After completing orthodontic therapy, children, adolescents and adults show improved body image and greater confidence – which translates into reduced anxiety in social situations. PubMed Central
TMJ status and the face
An improper position of the temporomandibular joint is often the hidden cause of malocclusions that affect the whole face. An untreated TMJ can lead to an open bite – the face appears “open”, with muscle tension visible at rest – or a retruded lower jaw, where the profile appears “bird-like” and the lower face loses its proportions.
Diagnostics – Comprehensive bite analysis based on digital or analogue bite registration. Craniofacial CBCT – assessment of the joint surfaces, airways and the bite–joint relationship.
A COMPREHENSIVE TREATMENT PLAN
Orthodontics that sees the whole.
A patient comes to us with crooked teeth, but may at the same time have worn teeth, lost natural anatomy or improper bite support. In such situations, simply lining the teeth up is not enough.
That is why we always look at the whole: how the teeth should meet, how they work during chewing and how they support the facial features. Sometimes this means combining orthodontics with restorative treatment.
Because the most beautiful smile is one that serves you for a lifetime.
WHAT DOES TREATMENT LOOK LIKE?

A smile that looks like yours – only healthier and lasting.

01
Consultation and diagnostics
We analyse the bite, facial proportions, bite registration, CBCT and the patient’s history.
02
An interdisciplinary plan
We define the scope – orthodontics, prosthodontics, surgery or a combination.
03
Treatment
Predictable stages – the patient knows what comes after what.
04
Retention and care
Maintaining the results for years – retention, check-ups, support.
TREATMENT METHODS

We choose the method to fit the patient – not the other way round.

Fixed braces
Metal, ceramic and self-ligating
Proven effectiveness for a wide range of malocclusions. Self-ligating braces – less friction, better hygiene, gentler forces.
More →
Lingual braces
WIN – completely invisible
Brackets on the tongue side – invisible from the outside, fully effective. The WIN system (Prof. Wiechmann) has the lowest decalcification risk of all fixed braces.
More →
Aligners
Invisalign & Angel Aligner
Clear, removable trays. A digital simulation of the result before treatment. Angel Aligner with the innovative angelButton – no additional attachments on the teeth.
More →
Early treatment · from age 6
Palatal expanders
Fixed expanders and the Hybrid Hyrax with mini-implants – widening the upper jaw without extractions, even in older teenagers and adults.
More →
TMJ · TMD
Relaxation and repositioning splints
A splint is often the first step before definitive treatment. It establishes the therapeutic jaw position – one in which the joint works without pain.
More →
Extraction-free treatment
Beneslider, IZC screws, skeletal anchorage
Thanks to skeletal mini-implants, in most cases we can avoid removing teeth. The face keeps its full, harmonious oval.

Diagnostics · everything in one place
Orthodontic consultation – full diagnostics on site
OPG, cephalogram, CBCT, digital scans and photographic documentation – analysis and a discussion of the treatment plan in a single visit. No further referrals.
