Functional orthodontics is a method of correcting jaw abnormalities in children and teenagers, which by affecting the jaw muscles and bones, solves problems such as the front or back of the jaw and irregular bite without pulling teeth.

This method of dental orthodontics has two types: fixed (more precise but more expensive and requiring high hygiene) and mobile (more convenient and cheaper but dependent on the patient's cooperation) and usually gives the best results between 6 and 14 years of age. Its advantages include prevention of surgery and improvement of facial shape and breathing, and its disadvantages are long treatment duration, high cost and dependence on regular use of the device.

What is functional orthodontics

Functional orthodontics is one of the newest orthodontic methods that can be used to solve the problems and abnormalities of the upper jaw and lower teeth. Mostly, this method is used for children and teenagers so that the jaws are formed without deformity and irregularity at the age of growth. Functional devices usually affect the muscles and bone structure of the upper and lower jaw and change and correct its position. In this case, without the need for tooth extraction, enough space is created for the teeth and even some problems such as sleep apnea and breathing problems are solved.

Types of functional orthodontics

Functional orthodontics is divided into two types, each of which has its own advantages and disadvantages, and each of which can be used for certain people. In the following, we will examine each of them and compare them and which of them is better for whom.

Fixed functional orthodontics

As its name suggests, functional orthodontics is permanently placed on the teeth and cannot be removed from the teeth until the treatment period is over. This model cannot be easily adjusted or replaced by the patient himself, and he needs an orthodontist to do it. In the beginning, it might be a little hard to get used to it; But you can easily eat or talk with it. Of course, you should know that in this type, because it is fixed and cannot be removed from the mouth, it is very important to observe oral and dental hygiene and clean it using special brushes for the orthodontic device.

Movable functional orthodontics

This device is made of plastic and the patient can take it out of his mouth while eating or cleaning his teeth. The cost of functional removable orthodontics is lower than fixed and is more popular among patients, and the patient must use it in the designated hours to get the full result. This model is mostly used for younger people who need frequent adjustment.

Is fixed functional orthodontics better or mobile?

It is impossible to say exactly which model is better, because each model is used for certain people; But according to the comparison table below, you can choose the best model. Of course, you must be careful that the orthodontist must finally approve the model.

Types of functional orthodontic devices

Special devices are used for functional orthodontics, the most important of which are the following.

Herbst appliance (fixed functional orthodontics)

This device is permanently installed on the molars of the upper jaw and moves it forward with gentle pressure on the lower jaw. This device is mostly used for severe dental overbite (the teeth of the upper jaw protrude from the teeth of the lower jaw) and undergrowth of the lower jaw.

Mara device

This device is also fixed and it is used to guide the lower jaw forward and align it with the upper jaw. Especially when the upper jaw protrudes more than the lower jaw.

Activator device

This device is mobile, and its different types include H activator, V activator and hyrax device, whose main task is to align the upper and lower jaw simultaneously.

Biotinor (functional lower and upper jaw device)

This device is mobile, which is used to move the lower jaw forward, and it is made of plastic. One side of this device is placed behind the upper jaw teeth and the other side moves the lower jaw teeth forward.

Twin block

This device works similar to Biotinor; But the difference is that it uses two parts to move the jaws so that the mouth and teeth are more comfortable. This device is mostly used to treat overjet or the horizontal distance between the front teeth of the upper and lower jaw and the growth of the lower jaw.
