무치악은 총의치나 임플란트 보철물로 수복이 가능하며 임플란트를 이용한 피개의치는 총의치보다 유지와 안정이 우수하고, 임플란트 고정성 보철물에 비해 저렴하고 심미적이다. CM LOC® Pekkton® 어태치먼트는 여자부가 poly-etherketone-ketone으로 마모저항성이 뛰어나다. 한편, SR Ivocap system은 가압주사성형법으로 의치의 수직고경 변화가 적고 강도가 우수하다. 본 증례에서 상악은 4개의 임플란트 식립 후 CM LOC® Pekkton® 어태치먼트와 SR Ivocap system을 이용한 임플란트 유지 피개의치를, 하악은 가철성 국소의치를 제작하였고 심미적 및 기능적으로 만족스러운 결과를 얻었기에 이를 보고하는 바이다.
Treatment options for edentulous patients are complete denture and implant prosthesis. A two implant-retained overdenture can be considered the first treatment in the edentulous mandible, but there is no clear consensus of treatment for edentulous maxilla. Implant-retention/support overdenture shows better retention and stability than complete denture and is less expensive and more esthetic than implant-supported fixed prosthesis. CM LOC® Pekkton® attachment is a solitary type attachment and evaluated to have excellent abrasion resistance and retention with a female part made of poly-ether-ketone-ketone. Meanwhile, SR Ivocap system is injection molding method and discussed to show few changes in the vertical dimension of denture and have excellent fracture resistance. In this case, we restored maxillary arch with a four implant-retained overdenture using CM LOC® Pekkton® and SR Ivocap system, and mandibular arch with a removable partial denture. Through this procedure, satisfactory outcomes were achieved both in functional and esthetic aspects.
