초록
부분 무치악 환자에서 구강 기능의 회복을 위한 보철 계획을 수립할 때, 잔존하는 치아에 따라 다양한 치료 방법을 선택할 수 있다. 특히 대합이 상실된 소수의 잔존치가 불안정한 교합을 야기하는 엇갈린 교합의 경우, 대합 되는 위치에 임플란트를 식립함으로써 교합지지를 회복할 수 있다. 이 증례에서는 발치 후 엇갈린 교합이 된 환자에서 의치의 하중을 견딜 수 있도록 상악 잔존치에 대응하는 하악 무치악 부위에 임플란트를 식립하고 자석유지장치(magnetic attachment)를 연결하는 국소의치를 제작하였다. 또한 상악 전치의 돌출과 하악 입술 지지도가 부족한 것을 개선하고 싶어한 환자의 요구사항에 따라 상악 전치부 보철적 수복 및 하악 의치를 통해 심미적 안모를 회복하였다. 5개월 정기검진 결과, 환자는 저작 기능 및 심미적인 면에서 만족하였고 의치의 안정성 또한 잘 유지되고 있기에 이를 보고하고자 한다.
Abstract
When attempting to restore the oral function of a partially edentulous patient, there are a number of prosthetic treatment options available, depending on the structure of remaining teeth. For example, when only one set of maxillary and mandibular teeth are diagonally in place across from each other, it is difficult to gain stable occlusion. In this case, implants can be put in place at the corresponding edentulous area to achieve balance. By doing so, a stable occlusion can be achieved. For this case report, a patient with crossed occlusion after extraction was treated with maxillary RDP (removable dental prosthesis) and mandibular implant-supported RDP (removable dental prosthesis). Moreover, an implant fixture was placed under the posterior molar of the distal extension base diagonally across from the remaining maxillary teeth. Then, magnetic attachment was implemented. According to the patient who received the treatment, the result was functionally and aesthetically satisfactory.
