Abstract

Recently, flexible denture is widely used with some advantages such as esthetics, flexibility and biocompatibility. However, there is an opposite opinion about stability because of the movement of denture by the material's flexibility. As the denture moves to tissue surface during mastication, it irritates the supporting tissue. It can lead to trauma and rapid resorption of residual ridges if this irritation lasts for a long time. In this case, the patient has used flexible denture with insufficient stability, retention and support for several years and thus continuous irritation of the supporting tissue resulted in palate bone exposure. The patient discomfort and palate bone exposure underwent improvements by the new denture with stability and retention. A careful case selection for flexible denture, regular checkup and proper treatment are necessary to prevent the side effects.

탄성의치는 심미성, 유연성, 생체적합성 등의 장점이 있어서 최근 많이 사용되고 있다. 그러나 재료 자체의 유연성에 의한 의치의 운동 때문에 안정성에 대한 문제가 제기되고 있다. 저작 시 의치가 조직면으로 움직이면서 지지조직을 자극하게 되고, 이런 자극이 장기간 지속될 경우 외상과 잔존치조제의 급속한 흡수를 야기할 수 있기 때문이다. 본 증례에서는 안정, 유지 및 지지가 부족한 탄성의치를 장기간 사용하면서 지지점막의 지속적인 자극으로 인한 구개골 노출이 발생하였다. 안정성 및 유지력이 확보된 새로운 의치를 제작하여 환자의 불편감이 감소하였고 구개골 노출이 치유되었다. 탄성의치를 사용할 수 있는 증례를 신중하게 선택해야 하며 정기검진 및 적절한 처치를 시행하여 부작용을 예방할 수 있어야 한다.
