Abstract

Purpose: The purpose of this study was to evaluate distalizing effects from the Pendulum appliance on vertical component of craniofacial structures. Materials and Methods: 20 Patients who visited for orthodontic treatments are assigned to two groups. Group I, SN-MP > 37 degrees are showing hyperdivergent pattern. Group II, 29 < SN-MP < 37 degrees are showing mesocephalic pattern. Each group are consisted of 10 people. Results and Conclusions: Differences between skeletal classifications result in significant differences at labioversion of lower incisors and distalized amount, which is larger at Group I (P <.05). Group II has only shown significant distalized molars (P < .05). Labioversion of lower incisors has not shown significant change. Skeletal anchorage-assisted Pendulum appliance doesn't deteriorate vertical component nor significantly improve.

목적: 골격성 고정원의 사용으로 고정원이 보강된 Pendulum 장치가 환자의 두개 안면 요소의 수직적인 부분에 미치는 영향을 분석하고자 하였다. 연구 재료 및 방법: 골격성 고정원과, pendulum을 이용하여 비발치 치료를 시행한 환자 중, 발산형 안모(SN-MP > $37^{\circ}$)와 중간형 안모($29^{\circ}$ < SN-MP < $37^{\circ}$) 각각 10명씩 분류하여 치료의 단기적 효과에 대해 분석하였다. 결과 및 결론: 골격 형태에 따른 차이로 발산형 안모군(HG)은 구치부 후방이동과 관련하여 하악 전치의 순측 경사가 유의하게 나타났다(P < 0.05). 중간형 안모군(MG)은 구치부의 유의한 이동만 나타났다(P < 0.05). 전치의 순측 이동은 유의성이 없었다. 본 논문에서 Pendulum 장치는 수직적인 안모 형태에 유의한 영향을 주지 않으며, 악화시키지 않았다.
