임플란트에 대한 급여의 확대로 임플란트의 지지를 받는 서베이드 고정성 보철물 제작 후 국소의치로 수복하는 증례에 대한 관심이 증가하고 있다. 이러한 증례의 예지성 있는 결과를 위해서 국소의치의 기본적인 설계 원칙과 잔존 치조골을 동시에 고려한 임플란트 계획수립이 필요하다. 본 증례는 편측 소수 잔존치를 가진 67세 남자 환자로 국민건강보험의 적용을 받을 수 있는 치료를 희망했다. CAD 소프트웨어를 활용하여 임시의치의 교합면, 국소의치의 기본적인 설계 원칙 및 흡수된 치조제를 모두 고려한 임플란트의 식립 위치를 결정하였다. 치료 결과 상악 및 하악 의치의 안정성 및 유지력이 적절하게 확보되었다. 본 증례는 임플란트 고정성 보철물 제작 시 국소의치의 기본적인 원칙과 흡수된 치조제를 모두 고려하기 위해 디지털 기술을 진단 및 치료에 활용하였고, 안정적인 결과를 얻었기에 이를 보고하고자 한다.
Abstract
As implant can be covered by National Health Insurance Service (NHIS), it was increased the interest in the removable partial denture (RPD) with the surveyed fixed prosthesis supported by implant fixture. To achieve predictable result, it needs the prudent implant planning by basic principles of RPD and patient’s residual ridge. This 67 years old age male had a few unilateral remaining teeth, and hoped the treatment covered by NHIS. As using CAD software, the position of implant is planned with regarding to occlusal table of provisional denture, basic principles of RPD, and resorbed residual ridge. The definitive prostheses can ensure the stability and retention of removable prosthesis. When planning implant fixed prostheses, the digital technique was utilized to consider basic principle of RPD and resorbed residual ridge. As a result, it provided satisfactory prostheses.
