초록

최근 들어 치아의 심미적인 개선을 위해 전치부 보철 치료를 하는 경우가 많다. 하지만 전치부 심미 보철치료이후 환자가 발음, 저작 등 기능적으로 불만족스럽게 생각하는 경우가 종종 있다. 전치부는 심미적으로 중요할 뿐만 아니라 교합과 관련하여서도 중심위 다음으로 중요한 전방유도가 성립되는 부분으로, 잘못된 전방유도 설정으로 인해 구치부의 교합간섭을 초래할 수 있다. 또한 새롭게 설정된 전치부 보철물의 전방유도가 환자의 기능로(envelope of function)과 조화를 이루지 않을 시 환자가 불편감을 나타낼 수 있다. 본 증례는 전치부 심미 보철 이후 부정확한 발음 및 안정적인 접촉이 없어서 불안정한 교합, 전반적인 불편감을 호소하는 환자에서 체계적인 진단과 치료과정을 통해 보철물을 재수복하여 환자와 술자 모두에게서 심미적으로, 그리고 기능적으로 만족스러운 결과를 얻었기에 보고하는 바이다.

Recently, many patients undergo anterior prosthetic treatment for esthetic reasons. In some patients complain about functional reasons such as inaccurate pronunciation and occlusal discomfort after the treatment. Anterior teeth are important esthetically but in the occlusal point of view, anterior guidance is the second most important factor in occlusion, next to centric relation. Failure to determine an appropriate anterior guidance might lead to posterior occlusal interference, which can highly affect the stability of the posterior teeth. Also, discomfort might occur if the customized interior guidance is not in harmony with the patient's envelope of function. The patient in this case complained of overall discomfort in the maxillary anterior area after prosthetic treatment. The expressed difficulty in pronunciation, unstable occlusion due to lack of stable holding contact and discomfort of the facial muscles. Maxillary anterior prostheses were refabricated through systematic diagnosis and treatment and thus, this case presents esthetical and functional satisfaction to both the patient and the dentist.
