Abstract

Patients with $Sj{\ddot{o}}gren^{\prime}s$ syndrome usually suffer from teeth discoloration and attrition due to xerostomia. If the anterior teeth are badly worn, problems such as loss of anterior guidance, occlusal disharmony, and limited space for restoration may occur. However, ideal occlusion is obtained in both centric and eccentric relation by regaining the disocclusion of the posterior teeth through the anterior and lateral guidance using twin-stage method. In this case, rehabilitation was performed for a $Sj{\ddot{o}}gren^{\prime}s$ syndrome patient with maxillary and mandibular incisor's severe attrition and teeth discoloration by using twin-stage method.

쉐그렌 증후군($Sj{\ddot{o}}gren^{\prime}s$ syndrome)을 가진 환자들은 구강건조증으로 인하여 치질이 연화되어 마모와 변색을 가지는 경우가 빈번하다. 전치부가 심하게 마모된 경우 전방유도의 상실 및 교합의 부조화, 보철수복을 위한 공간의 부족 등의 문제가 발생할 수 있는데, twin-stage method를 이용하여 수복시 전방유도와 측방유도를 통해 구치부 이개량을 확보하여 중심위와 편심위에서 모두 이상적인 교합을 형성할 수 있다. 본 증례는 쉐그렌 증후군으로 인하여 상, 하악 전치부의 심한 변색과 마모를 가진 환자에게 twin-stage method를 이용하여, 수복하였기에 보고하는 바이다.
