초록
최근 현대인들의 심미적인 치과 치료에 대한 관심이 증가하고 있고, 이와 관련된 다양한 재료와 수복물이 소개되고 있다. 특히 지르코니아는 우수한 강도와 내마모성을 지니며 생체친화성이 있다. 이러한 장점에도 불구하고, 지르코니아의 불투명한 백색으로 인해 전치부 수복치료시 심미적인 한계점이 있다. 최근 색조를 부여한 지르코니아 블록과 투명성이 높은 지르코니아 블록 및 다층 지르코니아 블록 등 다양한 지르코니아 블록이 개발되면서 단일 구조 지르코니아의 활용 범위가 확대되고 있다. 본 증례는 상악 전치부 보철물을 제작을 위해 단색의 Monolithic Zirconia를 이용하여 소결 전에 착색 용액을 도포하여 최종 수복물의 색조를 자연스럽게 재현하였다. 심미 보철 수복 치료시 착색용액을 이용한 지르코니아 사용을 통해 환자와 술자 모두 만족하는 심미적 보철물을 제작하였기에 이를 보고하는 바이다.
Abstract
Various materials and restorative options have been introduced recently with growing interest in esthetic dental treatment in modern society. Zirconia is especially known for its biocompatibility as well as remarkable toughness and resistance to wear, but it is limited in its use for esthetically focused treatment in anterior region for its white opacity. Lately the development of different kinds of zirconium blocks, such as colored block, clear block, and multi-layered block, allowed more extensive use of zirconia as a treatment option. This report describes a case, in which a prosthetic crown maxillary anterior region was stained with a combination of various coloring liquids before sintering to reproduce natural-looking color scheme in final restoration. The case was reported as the utilization of coloring liquid on monolithic zirconia crown could achieve esthetically satisfying prosthesis for both dentist and patient.
