Abstract

It is necessary to set the correct occlusal plane and to distribute the occlusal force uniformly considering the state of the opposing dentition during the prosthetic of the single edentulous patient with severe alveolar bone resorption. Implant supported overdenture is superior to complete denture in terms of maintenance and stability, and limited implants are used in fully edentulous patients with high alveolar bone resorption. Telescopic attachments using a newly introduced material based on poly-aryl-ether-ketone (PAEK) have the advantages of typical telescopic copping, excellent abrasion resistance, and are lighter and more economical than conventional implant overdentures. In this case, we restored maxillary arch with a implant retained overdenture using the telescopic attachment made of Pekktonand the mandible was restored with fixed implant prosthesis. Through these procedures esthetic aspects and functional outcomes were satisfactorily achieved.

심한 치조골 흡수를 동반한 편악 무치악 환자의 보철 수복시 대합치열의 상태를 고려하여 올바른 교합평면을 설정하고, 교합력이 균일하게 분산될 수 있는 치료가 제공되어야 한다. 임플란트 유지 피개의치는 소수의 임플란트로 치조골 흡수가 심한 완전 무치악 환자에게 총의치보다 우수한 유지와 안정성을 주는 치료이다. 최근 치과 영역에서 소개된 신소재 polyaryletherketone (PAEK) 기반의 폴리머(Pekkton ivory, Cendres + $M{\acute{e}}taux$ SA, Biel / Bienne, Switzerland)를 사용한 telescopic 어태치먼트는 전형적인 telescopic 코핑의 이점을 가지며, 내마모성이 뛰어나며, 기존의 임플란트 피개의치에 비해 가볍고 경제적인 장점이 있다. 본 증례에서는 상악 완전 무치악 환자에 임플란트를 5개 식립하여, Pekkton으로 내 외관이 제작된 텔레스코픽 어태치먼트를 활용한 임플란트 유지 피개의치를 제작하고, 하악은 임플란트 고정성 보철로 수복하였다. 심미적 및 기능적으로 만족스러운 결과를 얻었기에 이를 보고하는 바이다.
