골격형 Ⅲ급 전치개교와 과개교합에 대한 비교고찰 및 MEAW에 의한 치험예 = CONSIDERATION OF THE ANTERIOR OPENBITE AND DEEP BITE IN CLASS Ⅲ AND THEIR TREATMENT WITH MULTILOOP EDGEWISE ARCHWIRE (MEAW)

다국어 초록 (Multilingual Abstract)

The purpose of this report is to review vertical dysplasia such as open bite or deep bite in skeletal Class Ⅲ malocclusion and their treatment modality and to present two cases treated with MEAW.
The results obtained were as follows.
A. Open bite case
1. The treatment time was 3 year 8 months.
2. Upper and lower incisors showed extrusion and especially lower anterior alveolar process showed remodelling.
3. The mesially inclined upper and lower molars were uprighted and especially lower first molars showed extrusion that means remodelling of alveolar bone.
4. Normal over bite and over jet were established.
5. Mandible showed slight clockwise rotation.
6. Maxilla showed slight downward bending of ANS part.
7. Upper lip showed downward drop and lower lip showed retraction and touch between upper and lower lip was established.
8. Tongue posture of post-treatment was more raised than pretreatment.
B. Deep bite case
1. The treatment time was 1 year 8 months.
2. Upper incisors showed intrusion and labioversion and lower incisors showed slight intrusion and linguoversion.
3. The lower molars showed distal uprighting and intrusion and upper molars showed mesial movement and extrusion.
4. Normal over bite and over jet were established.
5. Maxilla did not show downward movement.
6. Mandible showed slight clockwise rotation.
7. Lower lip showed retraction and downward drop and upper lip showed downward drop.
