Abstract

Successful treatment of the non-growing patient with an open bite of either dental skeletal pattern often presents a difficult challenge. The morphologic pattern in anterior open bite is characterized by longer vertical dimensions, an increase in development of the maxillary posterior dento-alveolar structure and a steep mandibular plane. In such cases, molar intrusion would be a good remedy for treatment. This article reports the successful treatment and retention of two anterior open-bite cases. We used orthodontic mini-implants for treatment and a circumferential retainer with posterior bite block or skeletal fixed retainer for retention. The diagnostic criteria and mechanics for appropriate treatment are discussed. Our results suggest that open bite can be reduced successfully with intrusion of molars using orthodontic mini-implants (OMI) without orthognathic surgery, and that circumferential retainer with posterior bite block and skeletal fixed retainer are effective for retention.

성장이 종료된 치성 또는 골격성 개방교합 환자를 치료하는 것은 매우 어려운 일이다. 전치부 개방교합 환자는 증가된 전안면고경, 상악 구치부의 과도한 수직성장, 큰 하악각 등의 특징을 지닌다. 이러한 증례에서 구치의 압하를 통한 개방교합의 해소는 좋은 치료전략이다. 본 연구는 교정용 미니임플란트를 이용하여 개방교합을 치료하고 성공적인 유지를 얻은 두 명의 환자에 대한 보고이다. 적절한 진단이 시행되고 교정용 미니임플란트 등의 장치를 이용한 치료기법을 적용하면 수술치료 없이 교정치료만으로 개방교합의 치료가 가능하며, 하악구치부에 posterior bite block을 추가한 가철식 유지장치 및 SFR이 개교환자를 위한 유지장치 또는 보조유지장치로 유용하게 사용될 수 있다는 결론을 얻었다.
