Abstract

In removable dental prostheses, it is important to minimize impairment of residual tissue caused by wearing dentures. There are two factors that harm residual tissue. The first is functional load bearing of remaining teeth and alveolar ridges and the second is the effect of poor oral hygiene. Double crown retained removable dental prostheses provide rigid support, and it may reduce impairment caused by load bearing of alveolar ridges. Also, dental plaque and oral deposits, which are attached to outer crowns and dentures, can be easily managed extra-orally. In addition, it is beneficial to the health of the marginal gingiva because inner crowns have easy access for oral hygiene. In this case, double crown retained removable dental prostheses were used for the partially edentulous patient with severe residual alveolar bone resorption and poor oral hygiene, and the result was clinically satisfactory in terms of functional, esthetical, and oral hygiene aspects.

국소의치 수복에서는 의치 장착에 의한 잔존 조직의 위해를 최소한으로 억제하는 것이 중요하다. 잔존 구강조직에 위해를 가하는 첫 번째 요인은 잔존치 및 치조제의 기능력 부담이며 두 번째는 구강 위생관리 부족에 의한 영향이다. 이중관을 활용한 국소의치는 rigid support를 통해 치조제에 미치는 부담을 경감시킬 수 있으며, 외관과 의치부에 부착되는 치태 및 침착물을 구강 외에서 쉽고 확실하게 관리할 수 있다. 또한 내관인 지대치 역시 모든 방향에서 청소가 용이해 변연 치은의 건강에 유리하다. 본 증례에서는 심한 치조골 흡수 및 불량한 구강 위생관리를 보이는 부분 무치악 환자에서 이중관을 이용한 국소의치로 상, 하악을 수복하여 기능과 심미, 구강 위생 관리 측면에서 만족할 만한 결과를 얻을 수 있었다.
