Different types of narrowness and deviation of the jaw and the characteristics of each

tightness And The deviation of the jaware disorders in the position and coordination of the bones of the upper jaw (maxilla) and the lower jaw (Mandible) They cause disruption. These disorders can affect facial appearance, chewing, swallowing, speaking and even breathing. The classification of these disorders is usually based on the relationship between the maxilla and the mandible, known as malocclusion classes.. In this article from the site of Dr. Behnam Khorrami (Isfahan nose surgeon _ Jaw surgeon of Isfahan), we examine different types of narrowness and deviation of the jaw:

1. Class I malocclusion (Neutral malocclusion):

In this type, the relationship between the upper jaw and the lower jaw is normal. That is, the upper and lower first molars are in the same line. However, there may be other problems, such as crowded teeth, tooth rotation, or an overbite (Excessive coverage of the upper teeth over the lower teeth) Or overjet (Excessive protrusion of upper jaw teeth) to exist. Although these problems are classified as class I, they require orthodontic treatment.

Features:

• The relationship of the first molars: Rhinoplasty is performed to give the nose a perfectly shaped shape (in the same direction)
• There may be other problems such as crowding, teeth rotation, overbite and overjet.
• It usually requires orthodontic treatment.

2. Class II malocclusion (Retromandibular malocclusion):

In this type, the lower jaw is further back than the upper jaw. This means that the molars of the lower jaw are further back than the molars of the upper jaw. This type of malocclusion is often associated with an overbite (Excessive coverage of the upper teeth over the lower teeth) Is mobile. Class II is divided into two subgroups:

• Class II Division 1: Backwardness of the lower jaw compared to the upper jaw, with a large overbite.
• Class II Division 2: Backwardness of the lower jaw compared to the upper jaw, with moderate or low overbite, but with protrusion of the central teeth of the upper jaw..

Features:

• The lower jaw is behind the upper jaw.
• The molars of the lower jaw are further back than the molars of the upper jaw.
• Often associated with overbite.
• It may require orthodontic treatment or in severe cases, orthognathic surgery.

3. Class III malocclusion (Promandibular malocclusion):

In this type, the lower jaw is more forward than the upper jaw. This means that the molars of the lower jaw are more forward than the molars of the upper jaw. This type of malocclusion is often associated with overjet (Excessive protrusion of lower jaw teeth) and reverse overbyte (Covering the lower jaw teeth on the upper jaw teeth) Is mobile.

Features:

• The lower jaw is in front of the upper jaw.
• The molars of the lower jaw are more forward than the molars of the upper jaw.
• Often associated with overjet and reverse overbite.
• It usually requires orthodontic treatment or, in severe cases, orthognathic surgery.

Effective factors in causing narrowness and deviation of the jaw:

Several factors contribute to these disorders, including::

1. Genetics: Heredity plays an important role in determining the position of the jaws.
2. Environmental factors: Finger-sucking habits, pacifier use, mouth breathing, and improper chewing habits can affect jaw development..
3. diseases: Some diseases can affect the growth of the jaws.

Treatment of jaw tightness and deviation:

The treatment of these disorders is different depending on its type and severity and can include the following:

• Orthodontics: Using brackets or plaques to correct the position of teeth and jaws.
• ارتوگناتیک surgery: Surgery to correct the position of the jaw bones.
• Combined treatments: A combination of orthodontics and surgery to treat complex cases.

This article is only a general overview of the different types of narrowness and deviation of the jaw. For accurate diagnosis and treatment planning, it is necessary to see an orthodontist or maxillofacial surgeon. Each person with their unique characteristics needs a specific evaluation and treatment plan.
