INVITED LECTURE: Treating Class III maloclusion. Is there a limit between Οrthodontics and Surgery?
Class III orthodontic problems appear with the four following distinct types of malocclusions 1. Pseudo Class III 2. Midface deficiency 3. True mandibular prognathism and 4. Midface deficiency and mandibular prognathism. Diagnosis and differential diagnosis is essential for the application of the appropriate treatment protocol.
Reestablishment of normal function and occlusion is considered the most important treatment approach to prevent excessive mandibular growth or midface deficiency that results in a Class III malocclusion. Normal occlusion should be established from the age of 6 years in order to a. prevent progressive unfavorable bone and soft tissue growth, b. provide a more favorable environment for normal growth, c. improve function of the stomatognathic system and d. eliminate the probability for future surgery.
In the case that the Class III malocclusion remains untreated till puberty a differential diagnosis between Orthodontic Camouflage and Orthognathic Surgery must be done. Treatment Criteria for Orthodontic Camouflage are as follows: OC1.Average or short facial pattern, OC2.Mild anteroposterior jaw discrepancy, OC3.Crowding < 4-6 mm, OC4. Normal soft tissue features (nose, lips, chin), OC5. No transverse skeletal problem. On the other hand the treatment criteria for Orthognathic Surgery are the following: OS1. Long vertical facial pattern, OS2. Moderate or severe anteroposterior jaw discrepancy, OS3. Crowding > 4-6 mm, OS4. Exaggerated soft tissue features and OS5. Transverse skeletal component of problem.
Clinical cases of the four different Class III types with the treatment protocols are presented.
