How Does an Invisalign Retainer Work?
The treatment procedure for Invisalign involves the following steps:
Orthodontic diagnosis and preparation
The doctor will scan the patient’s current dentition using the latest imaging technology. Using the image, the doctor will determine appropriate treatment and form plans about the sequence of treatment.
Preparation of three-dimensional dentition computer model
The 3D model will be used to demonstrate the current condition of the patient. In this model, the doctor’s prescription will be applied, as well as the materials to be used for the procedure.
When the treatment plan is applied, the stimulation of the teeth movement will be demonstrated using the 3D model. It will also show the before-and-after-treatment demonstration of the patient’s teeth.
Construction of molds
The series of molds are similar to the patient’s dentition within the two-week stage of treatment simulation. These molds are customized and shaped for the patient’s teeth, which will give pressure to where the teeth will exactly move according to the desired alignment of the teeth. Often, the replacement of retainers happens every one to two weeks. However, it still depends on the prescription of the professional.
Benefits of Using Retainers
- Unlike traditional braces, these aligners are nearly invisible.
- The retainer and aligner are light, thin, and smooth. It provides more comfort, and it is safer and considered conventional for patients.
- Retainers are removable if you need to do difficult tasks, such as eating, brushing, and flossing. It can also help reduce the chance of having tooth decay and damage during the treatment.
- Invisalign is designed to correct the alignment of teeth but reducing unintended and unnecessary tooth movements.
- It reduces the chance of root resorption or damage on the roots of teeth from the pressure, as it is designed for short-time treatment unlike with traditional braces.
- It is more convenient to replace a lost or broken aligner because the next series of the aligner can be the replacement.
Limitations of Retainers
- The pricing policy of aligners varies for every professional.
- The manufacturing process of the actual series of aligners might take a month or more after the diagnosis and placement of treatment.
- According to research, a patient experiences relapse three years after the treatment from an aligner. However, this topic still needs further research.
- Aligners alone cannot treat severe Malocclusion, which may need a combination with other conventional braces to see results.
- The patients may experience a temporary period of irritated gums, cheeks, and lips that may affect speech.
