Abstract

Current trends in restorative dentistry focus on improving the esthetics and keeping the sound dental tissues as long as possible. The aims of this case report were to describe the successful outcome of cubic-phase zirconia laminate veneers for a patient with isolated microdontia by using a digital workflow, and to describe their clinical implications. A 15-year-old female who had isolated microdontia in combination with spacing visited Ajou University Dental Hospital for esthetic treatment. In this case, 6 maxillary anterior teeth were restored with cubic-phase zirconia laminate veneers without tooth structure removal by using a digital impression, computer-aided design (CAD) software, and computer-aided manufacturing (CAM) procedures. At 6-month follow-up, no distinct mechanical and biological complications were detected and the prostheses exhibited satisfactory esthetics and functions. Due to its favorable tissue responses and enhanced translucency, cubic-phase zirconia can be a suitable strategy for a noninvasive esthetic approach.

치아수복의 최신 경향은 심미적인 개선과 건강한 치아 조직의 유지에 중점을 둔 보존적 심미 치료이다. 본 증례에서는 디지털 워크플로우를 사용하여 왜소치 환자에서 고투명도 입방정상 지르코니아(5Y-PSZ) 라미네이트를 이용한 비침습적 심미 치료의 성공적인 결과를 보고하고 임상적 의의를 평가하였다. 왜소치의 가족력이 있는 15세 여자 환자가 상악 전치부의 심미적 개선을 주소로 아주대학교 치과병원을 내원하였다. 별도의 치아 삭제 없이 디지털 인상 및 캐드캠 시스템을 통해 적절한 출현윤곽을 고려한 고투명도 입방정상 지르코니아(5Y-PSZ) 라미네이트를 제작하여 상악 6전치를 수복하였다. 최종 수복물 장착 6개월 후, 기계적 및 생물학적 합병증은 발견되지 않았으며 기능 및 심미적으로 만족스러운 결과를 보였다. 지르코니아의 치주 조직 친화성 및 개선된 투명도로 입방정상 지르코니아(5Y-PSZ)는 비침습적 심미보철 재료로 고려될 수 있다.
