연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

Purpose: Orthognathic surgery is required in patients with severe skeletal disharmony and facial asymmetry, which results in functional and esthetic improvement. Recently, bimaxillary surgery has become generalized. Establishment of the occlusal plane among several other factors included in the surg...

제안 방법

  • This study was conducted on patients with the skeletal class III malocclusion, visited department of oral and maxillofacial surgery of Chosun Dental Hospital, from 2000 to 2007, and among patients underwent two-jaw surgery in the department of oral maxillofacial surgery at our hospital (Le Fort I osteotomy in the maxilla and bilateral saggital split osteotomy in the mandible), the difference of the mandibular set-back degree was less than 3 mm and thus severe facial asymmetry was not shown, and 20 patients able to followed up for minimum 1 year. All patients underwent orthodontic therapy prior to surgery, the fixation using miniplates was performed on the maxilla and the mandible, and after surgery, intermaxillary fixation was performed by placing splints approximately for 2 weeks. As the gender of the subject patients, the male was 14 patients and the female was 6 patients, their age distribution was form 18.
  • In this study, the horizontal as well as vertical relapse volume of the B point and the Pogonion point were examined. After longer than 1 year, the horizontal and vertical relapse of the B point was 0.
  • Therefore, in this study, the stability after two-jaw surgery was evaluated by measuring the standard plane present in the craniofacial plane, the B point in the mandible (Pogonion point), and the relation to the occlusion plane of which location is inevitably changed during two-jaw surgery.
