Abstract

The purpose of this case report is to introduce new attachment system(milled titanium bar with $Locator^{(R)}$ attachment) for implant supported overdenture in maxillary edentulous patients. A 56-years-old male patient visited the hospital due to the mobility of his maxillary fixed partial dentures(10-unit bridge). Including temporomandibular joint(TMJ), there was no specific PMHs to influence dental treatment. In radiographic and clinical evaluation, there was a severe bone resorption and mobility in maxillary teeth. Accordingly all the remaining maxillary teeth was extracted and fabrication of implant supported overdenture was planned. The milled titanium bar with $Locator^{(R)}$ was designed as an attachment system, considering the stability and retention of denture, masticatory efficiency, oral hygiene care, esthetics, pronunciation, and patient's financial state. The milled titanium bar was manufactured using CAD/CAM technology, and $Locator^{(R)}$ attachment connected to the bar by tap & drill method. For over 1-year, in terms of function and esthetics, satisfactory result was obtained.

본 증례 보고의 목적은 상악 무치악 환자에서 임플란트 지지 피개의치를 위한 $Locator^{(R)}$ attachment가 장착된 새로운 milled titanium bar를 소개하고 새로운 대안으로써의 가능성을 제시하고자 함이다. 56세 남자 환자가 상악 고정성 보철물(10-유닛 브릿지)의 동요도를 주소로 본원에 내원하였다. 악관절 및 치과 치료에 영향을 줄만한 특이한 전신병력은 없었다. 방사선 검사 및 임상 검사 결과, 상악의 경우 모든 잔존치아에서 심한 골흡수와 동요도를 보이고 있어 전악 발치를 시행한 후, 임플란트 지지 피개의치를 제작하기로 하였다. 의치의 안정성과 유지력, 저작효율, 청소의 용이성, 심미성과 발음 그리고 경제적인 측면을 고려하여 $Locator^{(R)}$ 어태치먼트를 CAD/CAM으로 제작된 milled titanium bar에 탭핑(tapping)으로 연결시키는 새로운 디자인을 고안하였으며, 1년 이상 경과 후, 기능과 심미적인 면에서 만족할 만한 성과를 얻었기에 이를 보고하는 바이다.
