Orthodontic treatment is a series of processes that move the teeth to the desired positions in the mouth by orthodontic appliances.

Orthodontic treatment is a complex dental treatment. Before commencing an orthodontic treatment, you should consult an orthodontist to understand your oral condition and the details of the treatment involved.

Purpose

To improve aesthetics
To improve the occlusion between the upper and lower teeth in order to improve the masticatory function
To improve the alignment of teeth so that a well-support denture / bridge can be fitted

B. Types of orthodontic appliances

1. Fixed orthodontic appliance

Materials and mechanism

Orthodontic brackets are attached to the tooth surfaces in appropriate positions so that when the orthodontic brackets and orthodontic wire are tied up, the spring back action of the orthodontic wire will move the teeth.
Gradually, the teeth are moved to the desired positions determined by the shape of the orthodontic wire.

Procedures for fixed orthodontic appliance

Placement of orthodontic brackets
The orthodontic wire and orthodontic brackets are connected by elastics and stainless steel wire (ligatures).
Regular dental visit should be made according to the instruction of the orthodontist to:
- Check the movement of the teeth
- Change the elastics or stainless steel wire
- Change the orthodontic wire
After the teeth have moved to the desired positions, a retainer is inserted to hold and stabilize the tooth positions.

Treatment duration

Overall treatment duration lasts for about one and a half to three years. The actual time needed depends on the complexity of treatment.

2. Removable orthodontic appliance

Materials and mechanism

Springs or screws are embedded in an acrylic plate, which is held in place by clasps, to move the teeth to their desired positions.

Procedures for removable orthodontic appliance

Impressions of the teeth are taken.
The removable orthodontic appliance is fabricated in the dental laboratory.
Adjust the springs and screws and let the patient try on the appliance.
Regular dental visits to check the tooth movements and adjust the springs.
After the teeth have moved to the desired positions, the removable orthodontic appliance will serve as a retainer to stabilize the tooth positions.

Treatment duration

The overall duration lasts for about 6 to 12 months. The actual time needed depends on the complexity of treatment.

C. Points to note on orthodontic treatments

If you are wearing orthodontic appliances, you should pay extra attention towards oral hygiene to prevent dental caries and periodontal disease.
If you are wearing a removable orthodontic appliance, the appliance and teeth must be thoroughly cleaned every morning and evening before wearing it again. Leave the appliance in plain water when it is not worn.
If severe discomfort is felt when wearing orthodontic appliances, consult your orthodontist immediately.
