Fixed dentures – tips and maintenance

Probably the most common and popular way to treat malocclusion is a fixed prosthesis. In some cases, treatment is even the only way to correct severe malocclusions. In this text, we will try to provide you with basic information about the fixed prosthesis, the method of maintenance and the process of placing the prosthesis.

The fixed dentures come with classic fixed braces attached to each dental plate, which are connected to each other with wire. The wire extends in the shape of an ideal dental arch and makes the necessary effort by continuously pressing on the teeth to move them to the ideal position. In order not to exert too much pressure, the treatment takes place in small steps.

There are several types of fixed dentures:

Metal locks
Ceramic locks
Self-ligating locks
Lingual technique
Retainer for teeth


Metal brackets are still the standard procedure in orthodontics today. Due to the widespread use of the fixed prosthesis technique, this form is widely accepted by young patients – they have become normal and are almost no longer perceived as aesthetically undesirable.

Advantage of metal locks:

Metal holders have lower friction values ​​than other materials. This means that the wire can slide well through the holder and that the friction forces do not make it difficult to move. This has a very positive effect on treatment. Metal brackets are a relief for the practitioner because, for example, when inserting a wire, the border of the lock can be better recognized.


Transparent and efficient

Ceramic braces are almost invisible because they are crystal clear and that is why your teeth look especially attractive. Also, the comfort is especially high. This means that: you can enjoy
daily treatment, because you know that your braces not only look worldly good, but also correct teeth very effectively.


Gentle tooth correction

Self-locking locks are so-called passive self-locking brackets. Self-ligating means that the wire in the holder is held by a special locking mechanism. Together with specially adapted braces, the self-locking bracket system allows the locks to move more freely and allows a gentle force to be used for the necessary movement of the teeth. The treatment time is reduced by an average of several months compared to conventional locks.


Invisible inside the tooth

The lingual technique is special tongue locks that are glued to the inside of the tooth, so that corrections of dental malocclusions are possible without anyone seeing the fixed locks. The world works with the established language systems of Incognito and OrthoRobot.


Straightened teeth for the rest of your life

Regardless of which method of treatment is used, after a successful treatment, the phase of later retention is very important. To prevent the teeth from warping again and to stabilize the ideal position of the teeth, fixed retainers are glued to the inside of the teeth.

The removable clasp gives the teeth space to break through. If almost all permanent teeth have erupted but are crooked, the attachments (locks and wires) must be attached to certain actuators to move the wire in the right direction.

Fixed prosthesis placement procedure

The metal wire is stretched in the shape of an ideal dental arch and moves the teeth, by applying force, slowly to the ideal position. In order not to exert too much pressure, the treatment takes place in many small steps.

Most surgeries work with the most modern pre-programmed bultibrand technology according to the latest scientific findings. Using high-quality supports with a low content of nickel and copper, as well as titanium and metal arches.

Alternatively, dentists use aesthetic transparent ceramic locks and self-ligating locks with reduced force. If you do not want the braces to be seen at all, a lingual treatment is recommended in which the braces are glued to the inside of the tooth (lingually). A carrier adhesive filled with fluoride-containing ionomer glass preserves fluoride during daily brushing.

Useful tips for a diet with a fixed prosthesis
