Abstract

It often happens that a removable partial denture needs to be repaired due to tissue changes in the remaining alveolar ridge, fracture of the denture, or fracture of the abutment tooth. There are several advantages to retrofitting a customized surveyed crown under the existing RPD. Retrofitting a crown to the RPD decreases the economic burden to the patient and avoids the need for several appointments to fabricate a new RPD. It is difficult for artificial teeth used to repair dentures due to fractured natural teeth to have a shape similar to that of natural teeth, and to repair aesthetic artificial teeth, it is necessary to manufacture customized artificial teeth similar to the shape of each patient's teeth. Recently, CAD/CAM technology has been used to fabricate customized prosthetics on existing RPD to achieve high retention and fitness accuracy, and by manufacturing customized artificial teeth, more aesthetic and harmonious artificial tooth repair is possible. This is a case in which a denture was repaired using a digital method to fabricate a customized prosthesis on an existing partial denture and customized artificial teeth that mirrored the adjacent dentition, saving time and cost, simplifying the process, and achieving aesthetically and functionally satisfactory results.

치조제의 조직 변화, 의치 또는 지대치의 파절 등으로 인해 국소의치의 수리가 필요한 경우가 종종 발생한다. 기존 국소의치의 금속 구조물에 맞는 보철물을 제작하면 몇 가지 장점이 존재한다. 환자의 경제적 부담이 줄어들고, 새로운 의치를 제작하기 위해 여러 번 내원할 필요가 없다. 자연치아가 파절되어 의치를 수리할 때 사용되는 인공치는 자연치아와 유사한 형태를 갖기 어려우며, 심미적인 인공치 수리를 위해서는 환자 개개인의 치아 형태와 유사한 맞춤형 인공치 제작이 필요하다. 최근에는 CAD/CAM 기술을 이용한 기존 국소의치에 맞는 보철물을 제작하여 높은 유지력과 적합도를 확보할 수 있으며, 맞춤형 인공치아를 디자인하여 더욱 심미적이고 조화로운 의치 수리가 가능하다. 디지털 방식을 이용하여 기존 국소의치에 맞춤형 보철물과 인접치열을 미러링한 맞춤형 인공치를 제작하여 의치를 수리한 증례로 시간과 비용을 절약하고 과정을 단순화하면서 심미적, 기능적으로 만족스러운 결과를 얻었기에 이를 보고하는 바이다.
