Open bite & modified Sato method

Traditionally, the treatment of an open bite has often been associated with corrective oral surgery. However, this procedure is invasive and associated with risks and a longer recovery time. Fortunately, orthodontics today offers a non-surgical solution for people with an open bite - the modified Sato method with invisible braces.

In our practices in Vienna and Linz, Dr Carina Wick, specialist dentist for orthodontics, has been successfully carrying out this treatment for years. Find out more about the advantages and procedure of Sato treatment here or make an appointment online for a non-binding initial consultation.

What is the modified Sato method?

With the classic braces treatment according to Sato, malocclusions that are difficult to treat, such as an open bite or a strong forward or back bite, can be treated quite effectively using a special strongly curved multi-loop wire and reliable co-operation

This method is named after Prof Sadao Sato from Japan and has already saved many patients with severe malocclusions from having to undergo surgery.

As treatment with this wire is very time-consuming to clean, we no longer offer the fixed Sato method with wire and brackets in our practices.

How does the modified Sato technique work?

For the treatment of an open bite, we have transferred the idea of the Sato method to modern treatment with invisible braces in our practice. This means that there is no need for the multiple bent wire (MEAW - Multiloop Edgewise Appliance or loop wire), but still requires the consistent use of so-called elastics, which must be clamped between the upper and lower jaw in addition to the invisible splints.

This results in a so-called chewing plane tilt, which causes the lower jaw to shift towards the upper jaw, thus correcting the malocclusion. A major change in profile, as is often typical in surgical orthodontic cases, only occurs to a very limited extent and must be assessed individually. However, for patients who want an aesthetic profile or facial change, oral and maxillofacial surgery would be recommended in addition to shaping the dental arches with braces.

What is an open bite?

An open bite occurs when the upper and lower teeth do not close properly and there is a gap between the incisors. This can have various causes, including genetic factors, thumb sucking, incorrect swallowing patterns or malocclusion. If left untreated, an open bite can lead to TMJ problems, jaw discomfort and even speech difficulties.

Treatment of open bite with invisible braces

Invisible braces, also known as transparent aligners, are an orthodontic method that makes it possible to correct misaligned teeth discreetly and effectively. Unlike conventional braces, they are made of transparent plastic and are virtually invisible. This makes them particularly attractive for adults and young people who want to correct their teeth discreetly.

Procedure of the modified Sato treatment

The treatment of an open bite with invisible braces is carried out in several steps. First of all, a comprehensive diagnosis is made in which your tooth and jaw structure is analysed in detail. Based on this information, we design a customised treatment plan for you. Then, customised transparent aligners are made to gradually move your teeth into the correct position.

During treatment, you will come to our practice regularly to receive new aligners and check the progress of your treatment. Each new aligner brings your teeth one step closer to the correct bite position. The total duration of treatment varies depending on the severity of the open bite, but it usually takes a few months to a year.

The advantage of invisible braces is their flexibility. Unlike traditional braces, clear aligners are removable, which means you can take them off to eat and clean your teeth. This allows you to eat without any restrictions and to easily maintain oral hygiene during treatment.

Important: Nevertheless, the aligners should be worn most of the day in order to achieve maximum results.
