Types of Braces

Fixed braces are little attachments (called “brackets”) bonded on the outside of the teeth – they allow the orthodontist to control the movements of the teeth in all three dimensions and are the most effective and efficient way to move teeth. Sometimes metal bands are placed around the very back teeth. Wires (called “archwires”) are locked into the slot in the brackets to control the tooth movements.

Damon self-ligating braces

The most usual braces are stainless steel bonded braces which, in this practice, are Damon self-ligating braces. These are a relatively sophisticated appliance that holds the archwire into the bracket in a much more secure manner than “traditional” braces that require tiny elastic bands or very fine wire ties, both of which can break, causing delays to treatment.

And, yes, you can still have colours with Damon braces!

Clear braces

Damon also makes clear brackets which are possibly the best of their type available.

Clear brackets are more fragile than metal brackets and at certain stages of treatment, progress has to be gentler. Often they are used for the upper front teeth only which is a good compromise between aesthetics and function. They are also slightly more expensive than metal brackets.

Invisalign uses a series of clear thin aligners shaped a bit like a mouthguard but covering only the teeth. The aligners are worn for about two weeks each and are individually manufactured with exact calculations to gradually shift teeth into place. The aligners are so clear it is likely that people will not know that they are being worn.

Being removable, they can be taken out for eating and drinking, and brushing and flossing the teeth. After a short initial period, patients get to the stage where they are quite unaware that they are wearing them.

All the aligners and the movement are customised for each individual patient. Before treatment starts, a 3-D “virtual reality” image of the teeth moving from start to finish is viewed. The orthodontist works with the patient to finalise the treatment plan.

Invisalign works well for minor problems, can be quite good for mild problems and generally is not recommended for moderate to severe problems. Some tooth movements are relatively straight forward and work well with Invisalign but, as Invisalign will advise, there are some movements that the technique has considerable difficulty with. Overall, Invisalign is the most “invisible” form of braces, but you must check with your orthodontist as to whether or not your problem is suitable for this treatment modality.


Lingual braces

These are stainless steel brackets placed on the tongue side of the teeth. Of all the fixed braces, these are by far the least obvious although they do have some disadvantages.

The main disadvantage is that they can interfere with speech and irritate the tongue but the vast majority of patients gradually adjust to this. They are also more difficult to clean and meticulous care must be taken of the gums on the inside. There are high technical costs involved in setting up these braces (which has to be done overseas) and it is much more difficult for the orthodontist and auxiliary staff to work on braces on the inside. Therefore appointments for lingual patients are longer. Most patients are happy to have lingual braces on the top teeth and ordinary braces on the outside on the lower teeth. The fee for this arrangement is approximately twice that of braces on the outside on all the upper and lower teeth.

Almost all orthodontic problems can be treated with lingual braces, including those patients who require jaw surgery.

固定矫正器是一些小的托槽(叫 “brackets”)粘 在牙齿的外面,钢丝(叫“archwires”)锁在托槽 里,从多方向移动牙齿。是非常有效移动牙齿的 方法.有时候,金属圈粘在后牙上。

Damon 之锁矫正器

大部分的矫正器是用不锈钢做的,我们诊所是用Damon 之 锁矫正器。这是一种相对复杂的矫正器,相比较传统矫正 器它能把钢丝锁着更紧。正常矫正器是用小橡皮圈或非常 细的钢丝节来固定矫正钢丝,它们容易损坏, 延迟治疗时间。

用Damon 矫正器也是可以有颜色的:

Damon 之锁矫正器也有透明的托槽,它们是所有的透明托 槽中最好的。

下面的矫正器是透明的,但传统的不锈钢Damon 矫正器是 效果最好的,不容易有问题。

透明托槽比普通的要容易损坏,所以操作需要比较轻。通 常适用于上前牙。它们也比通常的托槽要贵。

Clear Braces


Invisalign 是一系列每两周更换一副的无托槽隐形矫治器。每个矫治器均在精确计算后逐个生产以便逐步将您的牙齿 矫正到理想位置。

他们是可以在您吃东西,刷牙和用牙线拿下来。过了一段 时间以后,病人就不觉得他们自己戴着矫正器。由于您的 Invisalign 是根据您的牙齿量身定做的。从一开始就能看到 从开始到结束的情况。

它适用于比较轻度的病例,对重度的病例不太推荐。它只 能有限的移动牙齿,但有的角度不容易移动。Invisalign 是 最不易看见的矫正器,但必须联络矫正专科医生看您是否 适用于Invisalign。




最主要的缺点是它会影响正常发音和舌头的不舒服,但很 快就会习惯。而且它们不容易清洁,所以要特别注意清洁 舌侧的牙龈。 他们的制作成本很高(海外制作),操作困 难,通常我们需要操作的时间比较长。大部分病人喜欢上 隐型矫正器,下牙用普通的矫正器。 它的费用是普通的矫 正器两倍。
