Basic Principles for Clear Aligner Treatment

By Jerry 10.09.2022

Clear aligners, often known as invisible braces, are used to correct crooked teeth and bad bites. They are an almost undetectable, detachable substitute for braces that are made for comfort and adaptability. However, some movements may be more challenging to complete than with conventional braces since they aren't anchored to the teeth.

It's crucial that you understand the clear aligner's limits in order to correctly evaluate if they can provide the desired therapy results. Here, we will tell you more about these limits and the basic principles associated with them.

The following are the clear aligner principles you should keep in mind when using them for your patient:

Space is necessary for teeth to move

Due to your dentition, tight contact between teeth is frequent and exists naturally. The teeth are closely packed together that they physically exert pressure on one another. Depending on how much room is needed, you can decide to make space to allow teeth to move. Nonetheless, there may still be certain situations where there is not enough room. If enough pressure is applied, the adjacent teeth may simply slide in to fill the opening you've made. If this occurs, you might need to make more room than you had planned. Without doing this, the remaining motions will no longer have enough room to straighten out. As a result, the course of therapy may veer off course, and the aligners may no longer work. On the other hand, too much space between the teeth is undesirable. If a floss pops in and out with ease, the space is adequate. Approaches such as arch extension and IPR extraction may help solve space issues.

To move teeth, you need pressure

With a small bit of constant pressure, the majority of teeth will shift. However, some movements, particular types of teeth, and other variables are more susceptible to problems than others. They include molars, premolars, health and age of teeth, rotation, extrusions, and intrusions. The approach you can use to increase pressure are dimples, engagers, digital power chains, overcorrection, rotating with auxiliaries, and extruding with auxiliaries. The choice of the correction method will depend on preferences and the situation. For example, while dimples are the best choice for increasing aligner retention, digital power chains may be employed to close residual space resulting from excessive IPR.


Are there overall solutions to insufficient pressure and space?

Yes, there are techniques to aid in addressing insufficient pressure and space.

They are:

1.Long wear schedules: Used to help if you require more time to attain the desired tooth movements

2.Backtracking: You wear previous aligners longer prior to moving to the next step to aid in getting the teeth back on track

Final Word: Why address insufficient pressure and insufficient space?

You should always monitor and deal with insufficient pressure and insufficient space failure to which you will suffer undesired consequences, including:

Non-fitting aligners

Tracking problems

Prolonged treatment time
