Abstract

Long-term alveolar bone resorption in edentulous patient causes difficulty in denture use. Applying an implant overdenture with 2 to 4 implants to edentulous patient is easily approachable. Moreover, it improves denture stability, support, and retention. Milled bar, the attachment used in implant overdenture, can be used to induce better stability and retention to the supporting structure than conventional bar. It has become convenient to use due to the development of CAD/CAM system which had allowed the simplification of dental techniques. In this case, application of conventional maxillary full denture and mandibular overdenture made of CAD/CAM milled bar with 4 implants showed satisfactory results in the patient who had used upper and lower full dentures for a long time.

무치악 환자에서 치아 상실 후 오랜 기간에 걸친 치조골 흡수는 의치의 사용을 어렵게 한다. 하악 무치악 환자에게 두 개 혹은 네 개의 임플란트를 식립하여 임플란트 피개의치를 이용하는 방식은 쉽게 접근할 수 있고, 의치의 유지, 지지와 안정을 크게 향상시킬 수 있는 방법이다. 임플란트 피개의치에 사용되는 어태치먼트 중에서 milled bar는 기성 bar보다 상부 구조물의 견고한 안정성과 충분한 유지력을 얻기 위해 사용할 수 있으며, 최근 CAD/CAM system의 발달과 함께 기공과정이 간소화되어 이용이 용이하게 되었다. 본 증례는 오랜 기간 상, 하악 총의치를 사용했던 환자에게 상악은 전통적인 방식으로 제작한 총의치와 하악에 네 개의 임플란트를 식립하여 CAD/CAM milled bar를 이용해 하악 임플란트 피개의치로 수복하여 만족스러운 결과를 얻었기에 이를 보고하는 바이다.
