Abstract

In this case, the patient was restored with gold Hader bar mandibular implant overdenture using two implants about 10 years ago, and the retentive force was lost due to severe wear of the bar due to 3.5 years use. The overdenture was repaired using a Locator attachment, but the male part was completely worn after 6.5 years use. Finally, we used a hybrid telescopic double crown with a friction pin to fabricate a new implant overdenture, which was observed for 2 years and showed excellent prognosis. So, we describe the cause of failure of each attachment (Gold Hader bar, Locator) in two implant overdentures and report on the advantages and disadvantages of double crown implant overdenture and the conditions for success.

본 증례의 환자는 약 10여년 전 2개의 임플란트를 이용하여 Gold Hader bar 하악 임플란트 피개 의치로 수복하였고, 3년 6개월의 사용으로 인한 bar의 심한 마모로 유지력을 상실하였다. 이를 Locator 부착장치를 이용하여 하악 피개 의치를 수리하였으나, Locator 사용 6년 6개월 후 male 부위가 완전히 닳은 상태로 내원하게 되었다. 다음으로는 하이브리드 이중관(Hybrid telescopic double crown with friction pin)을 사용하여 임플란트 피개 의치를 새로 제작하였고, 이를 2년동안 관찰한 결과 우수한 예후를 보여주고 있다. 여기에서 한 환자에서 2가지(Gold Hader bar, Locator)방법으로 수복한 임플란트 피개 의치에서 각 부착장치의 실패원인에 대해서 알아보고, 이중관 피개 의치의 장단점과 성공을 위한 조건에 대해서 보고하고자 한다.
