Different kinds of braces

There are many different types of braces. In orthodontic practice, we also call them appliances. There are internal and external braces. For the internal braces, a further distinction is made between removable and permanent braces.

Removable appliance

Firstly, there are removable braces. These are so named because the person wearing them can put them into their own mouth and remove them. Removable braces are usually made of a type of plastic (artificial resin actually) into which metal wires are attached. In our practice, the following removable braces are used.

The plate

Plate Plate
Plate Plate

These braces consist of a resin plate that fits up against the palate. Metal wires are attached to the plastic to keep the plate in place in the mouth (clasps), and also springy wires that can displace the teeth (springs). A plate is often used to make the upper jaw wider as well. In this case, there is a screw in it that can be turned open. The plate is best worn day and night (24 hours) and only removed for brushing the teeth. It’s also best to learn to eat with the plate in the mouth. Getting used to a plate usually proceeds very smoothly. In the first week, you may be troubled with too much saliva and have difficulty swallowing and speaking. A plate is usually used for the upper teeth. In some cases it can also be used for the lower teeth.

The activator

Twin block

The activator, also called block braces, is used to stimulate lower jaw growth. After this phase of the treatment, which usually lasts for 9-12 months, your upper and lower jaw will fit together better. This means you can use your teeth and jaws better and your lower lip will no longer sit between your front teeth. Your appearance will also change. Apart from stimulating lower jaw growth, an activator can also be used to widen the upper jaw. In this case, there’s also a screw in the top part of the activator.The activator ensures that the muscles that are attached to your lower jaw become stronger. At the beginning, you’ll feel some muscle ache. Once your muscles have become strong enough, they will hold your lower jaw in the new, correct position. Only then can the lower jaw really start to grow (bone development around the joint). An activator only works if it’s worn for 14-16 hours a day, except during eating, doing sport and brushing. When you bite wearing braces, you are obliged to do this in a very different way from what you were used to. Swallowing and speaking are also very different. This is actually the intention. Of course, at the beginning, you’ll have to get used to your activator. At the beginning, many patients suffer from a tired feeling and pain in the jaw muscles, difficulty speaking, sensitive teeth, a lot of saliva and/or hissing speech.  As a rule, these complaints don’t last long. The better you wear the activator, the more quickly they will disappear. At the beginning, it can also be that there are sharp edges on the braces. If so, do mention it – we’ll just grind a little of the resin off the braces.The activator is usually worn for from 9 to 12 months. After this phase of jaw correction, in almost all cases, there follows a second phase with a fixed appliance for the necessary tooth position corrections.


The EVAA activator

These are also a type of block braces and, just like the activator, they are used to correct the forwards and backwards jaw alignment. The EVAA is a type of activator that can be combined with a permanent appliance in the upper and/or lower jaw. It’s not however possible also to widen the upper jaw with this type of block braces. The recommendation for the wearing of this activator is the same as that for the ordinary activator (14-16 hours).



Headgear is also called external or outboard braces. These braces retard the growth of the upper jaw and displace the molars backwards. In this way, the jaws will fit together better. Part of the headgear fits inside the mouth and part outside. Bands with tubes are installed around the molars in the upper jaw. The headgear’s inner ring is slid into the tubes and the outer ring is attached to a neckband. You must wear this headgear for 14 to 16 hours a day and it is often used in combination with other orthodontic appliances. There are also types of headgear that are attached to sort of cap on your head rather than a neckband, but these are used less often.



Invisalign corrects your teeth using a number of invisible removable sheaths. These are custom-made. They must be replaced every two weeks. In this way, the teeth move very gradually into the desired position. The Invisalign appliance must be worn 24 hours a day. Sometimes it is necessary to put small, white fillings into your teeth for firmer support.


Permanent appliance

Bracket braces

Bracket braces

These permanent braces, also called plate or bracket braces, cannot be removed from the mouth by the wearer. These permanent braces consist of brackets that are bonded to the teeth. Metal rings (bands) are sometimes put around the molars. These brackets and bands together provide an attachment for the wire (arch) that is installed into the brackets. These arches are very flexible, thermally sensitive and have a kind of ‘shape memory’. The teeth are displaced by constant, gentle and carefully-controlled biocompatible forces. The gentle force of this orthodontic arch ensures that the brackets move the teeth gradually and with no or only minimal sensitivity. The teeth are moved through their surrounding bone and supporting tissue to the desired position in the jawbone. This is possible through the physiological conversion process of bone apposition (formation) and resorption (breakdown). We use the latest ‘self-ligating’ technique to allow us to offer our patients the best care and quality. With us, you can also opt for less-visible bracket braces made of ceramic.

This ‘self-ligating’ technique and the associated highly flexible arches mean the forces are very small. The use of small forces also means less tooth sensitivity. However, after every visit to the orthodontist, sensitivity in the teeth can occur, but it generally passes within a few days. At the beginning, you might suffer from minor wounds inside your mouth. By applying a bit of sticky wax to the sharp parts of the appliance, you can relieve the irritated places somewhat.

Usually, the orthodontist will ask you to wear elastics during the treatment. If you wear the elastics properly and according to the instructions, this will have a major effect on the length of your treatment. It’s most important that you are careful with your bracket braces. Hard food (such as apples, French bread and nuts) and sticky sweets (like toffee and chewing gum) are best avoided. Permanent appliances are not harmful to the teeth when you brush properly. However, plaque formation around the brackets can lead to calcium loss from the enamel and initiate cavities. Brushing properly several times a day is therefore necessary and you should drink as little soft drinks and/or fruit juice as possible.

Lingual technique

Lingual Lingual

Adults sometimes have aesthetic objections that the braces are visible. To address this, we can place the brackets on the back of the teeth. This is called the lingual technique. It requires more treatment time and is therefore more expensive. Keeping the teeth clean demands somewhat more time and care, because you have no view of the brackets and gums.


Suture expansion appliance

Suture expansion braces, also called Hyrax, butterfly or spider braces, widen the upper jaw. With these braces too, rings (bands) are used to attach the appliance to the molars. A metal structure then runs over the palate with a screw that can be tightened on the orthodontist’s instructions. By undoing the screw, the palate becomes wider relatively quickly. A wide gap develops between the front teeth and the molars of the upper jaw fit better with those of the lower jaw. After achieving the right width, this appliance remains in the mouth for some months to stabilise the new width. After this first widening phase, a second treatment phase with a fixed appliance always follows. Getting used to the suture expansion device usually proceeds very smoothly.

Forsus Springs

Forsus Springs are attached to the permanent braces. They are not braces in themselves, but rather an addition to bracket braces just as elastics are. They are also often used instead of elastics when those are worn too little or do not achieve the envisaged result. The springs stimulate the forwards growth of the lower jaw and move the teeth in the upper jaw backwards. This reduces the overbite (overjet). The effect of the Forsus Springs is more ‘dental’ (teeth) while that of the block braces is more ‘skeletal’ (bone). Depending on the correction desired, the springs are worn for between three and nine months. The springs may cause a tired and painful feeling in the jaw muscles at the beginning. Small wounds may also develop on the inside of the cheeks. By applying a bit of sticky wax to the sharp parts of the appliance, you can relieve the irritated places somewhat. Generally you will be completely used to the springs in a few weeks.


Retention period and aftercare

Usually, towards the end of the active treatment, splints are bonded behind the upper and lower teeth. These are thin, braided wires that are bonded to each tooth with a small drop of adhesive. In the upper and lower jaw, from canine to canine. These splints give the teeth the support they need to remain in their new, straight position. If a splint comes loose, an appointment must be made immediately to attach it again. If the splint remains loose for too long, the teeth could shift. Also, if you think there is a change in the position of your teeth, you should make an appointment to have this looked at. The intention is that these splints remain in place for a long time and provide support. In fact, these splints are not usually removed. If the dentist considers it necessary to remove a splint temporarily (e.g. if a cavity needs to be filled), this is possible. Just call and make an appointment.

Hawley OIR
Hawley OIR (SX)

After we remove the bracket braces, you return once more for a splint check-up and we assess whether the final result is still good. These check-ups are after eight weeks, six months and 18 months. After this, the dentist takes over. After three years, we invite you once more to check the splints. If necessary, we take an overview X-ray to examine your wisdom teeth.

A splint isn’t sufficient to prevent your teeth from moving again. Therefore, the orthodontist will advise you to wear night braces as well as the splint. We have two types of night braces, Hawley and OIR (SX).
