Abstract

Objectives : The conventional removable appliance, composed of wires and acrylic resin, had unaesthetic results and poor retention. The flexible denture, as an alternative, presents improved aesthetics with the thin and strong resin retentive area. In addition, it also enhances patients' sensory function as a result of decreased volume of denture base. The flexibility of the flexible denture reduces the possibility of fracture and distributes the masticatory forces transmitted to the abutments and residual bone tissue. This report describes a 10-year-old girl and a 6-year-old boy with oligodontia treated with the flexible dentures as an alternative to conventional removable appliances. Methods : Impression was taken using alginate material and sent to a laboratory with the bite for fabrication of the flexible denture. Prior to try-in, the flexible denture was immersed in water at $90^{\circ}C$ for one minute and cooled. Impinging area of the denture was checked by $Fit-Checker^{(R)}$ and removed and the denture was delivered to the patient. Results : Both patients were satisfied with the flexible dentures, which presented improved retention and aesthetics. Conclusion : For patients with oligodontia, flexible dentures can be considered as a treatment of choice, which may replace the conventional denture.

부분무치증 환자에게 사용되어온 기존의 가철성 장치는 wire의 노출로 인한 비심미성과 낮은 유지력 등의 문제점을 가지고 있다. 그 대안으로 제시된 탄성의치는 치은의 자연적인 색조를 투과시키는 얇고 강한 레진유지부로 인해 심미성이 크게 향상 되었으며 전체적인 의치상의 크기를 줄여주어 환자의 감각을 더욱 향상시킨다. 탄성의치의 유연성은 파절가능성을 감소시키며, 내재적 응력의 해소 작용으로 지대치와 잔존 골조직에 전달되는 저작력을 분산시킬 수 있다. 본 증례에서는 부분무치증을 보이는 10세 여아와 6세 남아에서 기존의 가철성 장치를 대체한 탄성의치를 사용하여 양호한 치료결과를 얻었다. 알지네이트로 상하악 인상을 채득하고 교합관계를 인기한 뒤 기공소에 제작을 의뢰하였다. 다음 내원 시 탄성의치를 $90^{\circ}C$의 물에 1분정도 담가두었다가 꺼내어 서서히 식힌 뒤 구강 내에 시적하였다. 레진유지부의 적합성을 확인하고 $Fit-Checker^{(R)}$를 이용해 조직이 심하게 눌리는 곳을 삭제하고 장치를 장착하였다. 두 명의 환아 모두 탄성의치의 더 나은 유지력과 향상 된 심미성에 만족하였다. 탄성의치는 부분무치증 환자에서 기존의 가철성 장치를 대체할 수 있는 좋은 재료로 여겨진다.
