Crossbite: A Type of Malocclusion
A crossbite is often referred to by your orthodontist as prognathism or protrusion of the jaws. In this article, we simplify and clarify this condition.
What Is a Crossbite?
First of all, a crossbite, scientifically known as prognathism, is a type of dental malocclusion where one or more lower teeth are outside the upper teeth while eating.
This malocclusion can be particularly uncomfortable and annoying, especially during meals, but can also lead to long-term difficulties with speech.
Are There Different Forms of this Dental Malocclusion?
The short answer to this question is: yes.
A more detailed answer shows that this malocclusion can present several forms, necessitating a more precise definition.
In this case, crossbite may first and foremost involve one or more teeth at a time. It can occur at either the front or back of the dental arch. The dental arch can be defined as “the curved structure that houses your teeth and consists of the supporting gum and alveolar bone”.
Finally, a crossbite may be associated with other malocclusions that are already present. In this case, the orthodontist will have to treat all these malocclusions as a whole.
Dr. Normand Bach, an experienced orthodontist in Montréal, will be able to determine precisely the treatment that is most adapted to your condition. He will take into account many factors, such as your age, the number of teeth involved in the crossbite, the origin of the misaligned teeth and your general condition. Other factors may also be considered.
Types of Crossbite
Although there are many studies on the subject, there are generally two types of crossbite:
- Anterior crossbite
- Posterior crossbite
The first type of this malocclusion mainly concerns the front teeth, while the second type involves the back teeth. However, both types of crossbite can occur in combination, which is why the orthodontist needs to make the right diagnosis for optimum treatment.
Let’s go a step further. In the literature, crossbites are generally classified based on the location of the malocclusion. Consequently, the anterior crossbite, which, as we already mentioned, occurs at the front teeth, is more apparent. Patients can easily see this themselves.
On the other hand, the posterior crossbite in the back teeth is less noticeable.
How Is Crossbite Treated by Your Orthodontist?
First of all, it’s important to stress that the approach will be different for children and adults.
Scientific references1 on the subject show that the sooner the intervention is carried out in children, the better the results. After the age of 13 or 14, treatment is more complex.
Treatment of crossbite in children does not require surgery.
The orthodontist will first try to gradually widen the upper jaw with braces. This phase of the treatment is fairly quick. It is followed by general alignment with another appliance.
Crossbite is best treated in children between the ages of 7 and 14.
In adults, treatment will depend on the patient’s specific situation and objective.
There are non-surgical treatments that work. One example is an alignment treatment in which the orthodontist seeks to improve the angle of your teeth. This compromise treatment should be discussed with the patient beforehand.
For example, if the crossbite involves a single tooth that is incorrectly positioned in the mouth, a simple alignment will give the desired result. But in the more complex case of a crossbite affecting several teeth, surgery will be essential.
In the case of a simple malocclusion, treatment with Invisalign aligners can correct an aesthetic situation. The treatment plan will be quite straightforward and spread over several months.
In short, in adults, there are two alternatives to consider: in one case, the crossbite can be treated without surgery. In the other case, surgery is required, especially if the jaw has to be widened. Once again, only your orthodontist can advise you on the appropriate treatment plan. Each situation is carefully evaluated.
