가철성 국소의치에서 지대치는 국소의치의 지지, 유지, 안정에 필수적으로, 기능적인 의치제작의 중요한 요소이다. 치주적으로 건전한 지대치가 충분하고 양측으로 위치할 경우 기능적인 의치 제작이 용이 하겠지만, 지대치가 부족하거나 편측에 위치하는 경우에는 생역학적으로 불리하여 기능적인 의치를 만들기가 상대적으로 어렵다. 한편, 최근에는 임플란트 서베이드 크라운을 이용해 지지, 유지, 안정 세 요소를 보강하는 임플란트 지지 국소의치가 치료 계획으로 많이 선택되고 있다. 특히, 소수 잔존치만 남은 경우에 임플란트 서베이드 크라운을 추가함으로써 저작 능률, 심미, 환자의 편안감, 발음의 개선 등을 얻을 수 있다. 본 증례는 하악에 편측 소수 잔존 지대치를 갖는 환자에서 반대편 소구치부에 임플란트 서베이드 크라운을 추가하여 양측성 후방연장 국소의치를 제작하였다. 지대치의 비대칭성을 해소하였고, 환자와 술자 모두 만족하는 결과를 얻었기에 본 증례를 보고하는 바이다.
Abstract
In removable partial dentures, abutment teeth are essential for support, maintenance, and stability of partial dentures, and are an important factor in the fabrication of functional dentures. If the number of periodontally sound abutments is sufficient and they are located on both sides, it will be easy to manufacture functional dentures with good support, maintenance, and stability. But on the contrary, if the number of teeth is insufficient or if they are located on one side, it is biomechanically disadvantageous and relatively difficult to make functional denture. On the other hand, recently, implant-supported removable dentures, which reinforce the three elements of maintenance, support, and stability by using implant surveyed crown, have been frequently selected as treatment plans. In particular, by adding an implant surveyed crown when only a small number of residual teeth remain, mastication efficiency, esthetics, patient comfort, and pronunciation can be improved. In this case, bilateral posterior extension partial denture was fabricated using implant surveyed crown as abutments by placing implants in the premolars area opposite to the residual tooth unilaterally in the mandible. As a result, the asymmetry of the abutment was resolved, and the maintenance and stability of the denture was achieved.
