초록
임플란트를 이용한 수복 치료에서 장기적인 안정을 얻기 위해서는 임플란트의 식립 시 보철 수복에 이상적인 위치와 각도로 식립하는 것이 중요하다. 이를 위해서는 정확한 치료계획에 따른 수술과 보철 치료가 이루어져야 한다. 본 증례에서는 캐드캠 기술을 이용해 수술 계획 수립, 고정성 임시 보철물 및 최종 보철물 제작을 진행하였다. 최종 보철물을 고려하여 제작한 수술용 가이드로 임플란트를 식립하였다. 임시 의치가 가진 환자의 심미적 정보를 고정성 임시 보철물과 최종 보철물의 제작에 활용하였다. 최종적으로 단일구조 지르코니아를 이용한 전악 임플란트 고정성 보철 수복으로 기능 및 심미적으로 환자가 만족할만한 결과를 얻을 수 있었다.
Abstract
Installation of dental implants at optimal angles and positions is critical in longterm stable implant-supported restorations. Surgery and prosthodontic procedures should be performed accurately as the treatment is planned. In this clinical case, Computer aided design and manufacturing technology was used not only to establish a precise surgical plan, but also to fabricate both provisional and definitive fixed prostheses. A surgical guide was designed to install the implants at proper positions for the definitive prostheses. The patient’s esthetic information, which was necessary for the new provisional and definitive fixed prostheses, was obtained from the existing temporary dentures. Finally, the complete mouth fixed implant-supported rehabilitation using monolithic zirconia provided the patient with functionally and esthetically satisfactory prostheses.
