Abstract
결 론
저자들은 서울대학교병원 소아치과에 내원한 Ⅱ급1류 부정교합을 Twin Block을 이용하여
치료하고 다음과 같은 결과를 얻었다.
1. 2-3개월 내에 빠른 안모의 개선이 이루어졌다.
2. 환자의 협조도가 양호하였다.
3. 과도한 수평피개 및 수직피개가 감소되었다.
4. 구치관계가 Ⅱ급에서 I급으로 개선되었다.
#초록#
Twin Blocks are simple bite-blocks that effectively modify the occlusal inclined plane
to induce favorably directed occlusal forces by causing a functional mandibular
displacement. These devices use upper and lower bite-blocks that engage on occlusal
inclined planes.
Twin Blocks use the forces of occlusion as the functional mechanism to correct the
malocclusion. To get an excellent result in the treatment by using the Twin Block
appliances, proper case selection must be needed.
Twin Block treatment is performed in two stages. Twin Blocks are used in the active
phase to correct the anteroposterior relationship and establish the correct vertical
dimension. Once this phase is accomplished, the Twin Blocks are replaced with an upper
Hawley type of appliance with an anterior inclined plane, which is then used to support
the corrected position as the posterior teeth settle fully into occlusion. The Twin Block
is the most comfortable, the most esthetic tone the most efficient of all the functional
appliances. Twin Blocks leave many advantages compared to other functional appliances.
Patients can wear Twin ;Blocks 24 hours per day and can eat comfortably with the
appliances in place. From the moment Twin Blocks are fitted, the appearance is
no-ticeably improved. There is less interference with normal function. Integration with
con-ventional fixed appliances is simpler than with any other functional appliance. Twin
Blocks allow independent control of upper and lower arch width. Appliance design is
easily modified for transverse and sigittal arch development.
The authors treated Class Ⅱ malocclusion with Twin Blocks, and the results as
follows ;
1. Rapid profile improvement was achieved in 2-3 months.
2. There was excellent patient cooperation.
3. Severe overjet and overbite were reduced.
4. Class Ⅱ molar relationship was changed to Class Ⅰ.
