Abstract
세라믹 재료의 기계적, 광학적 특성의 향상과 상아질 접착제의 발달로 심미성이 요구되는 전치부 수복 시 보다 성공적인 결과를 얻을 수 있게 되었다. 그 중 PLV (Porcelain Laminate Veneer)는 치아 삭제를 최소화하면서 보존적인 방식으로 심미적 개선을 이룰 수 있다. 20대 여성 환자가 상악 전치부의 심미적 개선을 위해 내원하였다. 환자의 주소는 외상 및 근관치료 후 발생한 지대치 변색이었고, 최소한의 치아 삭제를 원하는 환자의 요구를 반영하여 porcelain laminate veneer 수복을 결정하였다. PLV의 재료로는 높은 광투과성과 강도를 가지는 리튬 디실리케이트계 세라믹을 선택하였다. 더불어 수복물의 내면에 라이너를 처리하여, 자연 치아과 유사한 색조와 투과율을 갖는 본 소재의 심미적 특성을 유지하면서도 지대치의 변색을 효과적으로 차단하여 만족스러운 결과를 얻었기에 이를 보고하는 바이다.
Improvements in the mechanical and optical properties of ceramic materials and the development of dentin adhesives have resulted in more successful results in anterior teeth restorations. Among them, porcelain laminate veneer (PLV) can achieve aesthetic improvement in a conservative way while minimizing tooth reduction. A female patient in her 20s visited for aesthetic improvement of the maxillary anterior teeth. The patient"s chief complaint was aesthetic improvement of tooth discoloration after trauma and endodontic treatment, and a PLV restoration was decided to reflect the patient’s demand for minimal tooth reduction. IPS e.max Press, a lithium disilicate-based ceramic with high light transmittance and high strength, was chosen for porcelain laminate veneer. Inner surface of the veneer was treated with liner in order to block discoloration of the abutment teeth while maintaining translucency in the incisal edge. The patient was satisfied with the aesthetic result.
