Treatment of SKELETAL class III (Karen McDonagh)

Although the traditional orthodontic treatment, for developing class malocclusion, focused in the jaw as the primary cause of discrepancy, recent studies have suggested that 63% of skeletal class III malocclusions display retrus?o jaw. Most patients tend to present maxillary hypoplasia in conjunction with a normal or slightly prognata jaw.

Unfortunately, I also see many young patients, for a second opinion, who are told that there is nothing that the orthodontist can do but wait until your facial growth is complete and then work them for orthognathic surgery. Although most surgical procedures to correct the poor class involves advances JAWS! This suggests that the problem has never been excessive mandibular growth, but rather a lack of jaw development. Such problems may have been caused by nasal obstruction, when the child was younger.

Orthodontic treatment for malocclusion of class can be defined in the following categories:

1. growth Modification involving jaw expansion and protraction face mask therapy

2. growth Modification involving a cup of Chin to curb the mandibular growth, or

3. wait until growth ceased, thus compromising the patient for dental camouflage treatment or orthognathic surgery.

In my orthodontic practice, children exhibiting the first signs of a class III malocclusion are priority for treatment. My current treatment approach involves development of jaw and protraction, but I did not use Chin cups as I feel that they have an adverse effect on the temporomandibular joints.

Controversy currently exists as the ideal time to begin orthodontic treatment of class. Takada examined maxillary protraction therapy and reported that the time frame mid-pubertal and prepubertal is better, due to the natural growth of the jaw (stage C2-C3).

GOALS OF TREATMENT FOR THE PATIENT:

If we treat the patient as early in the growth cycle as possible, i.e. as soon as the problem of class III can be diagnosed, the following treatment goals can be reached:

1. reduce the growth of the size of the jaw.

2. increase the size of the jaw to its maximum genetic potential, and

3. move the jaw forward to its maximum genetic potential.

It is essential to confirm the diagnosis of class III malocclusion and formulate a plan of non-surgical or surgical treatment, a cephalometric analysis.

I personally use the cephalometric analysis of Jefferson as this is ideal for the correct diagnosis of a class III patient. Jefferson's jaw size and the position of the jaw can be easily related to the length and position of the cranial base. The size of the jaw and the jaw position, can also be related to the size and position of the cranial base.

The cephalometric analysis Jefferson offers a visual easy means identifying maxillary/mandibular disproportions
