Abstract

Mini-implant has been reported as an alternative method to conventional diameter implants in the treatment of mandibular anterior region with narrow ridge. However, one-piece type mini-implant showed biological and technical complications, such as peri-implantitis by residual cement and prosthetic detachment. Recently, one-piece type mini-implant with additional retentive structure has been introduced to increase the retention and stability of the mini-implant. The mini-implant is based on spreading the upper retentive structure with a spreader and connected it with the inner surface of the zirconia prosthesis. In two cases, we tried to reduce these complications through the mini-implant on the narrow mandibular anterior region, and it was possible to reduce the overall treatment period through a digital system. In this case report, restoration using the digital mini-implant system showed improvement of patient satisfaction on the aspect of function and esthetic in the narrow mandibular anterior region.

하악 전치부와 같이 골 폭이 좁은 환자에서 미니 임플란트 사용은 기존의 직경 임플란트의 대안으로 보고된다. 그러나, 기존 일체형 미니 임플란트의 사용시 보철물 탈락과 시멘트 사용으로 인한 임플란트 주위염과 같은 합병증의 발생이 보고되고 있다. 최근 미니 임플란트의 유지력 및 안정성을 높이기 위해 상부에 부가적인 유지구조를 가진 일체형 미니 임플란트가 소개되었다. 상부 탄성부를 스프레더로 벌려 줌으로써 지르코니아 보철물 내면의 결합구조와 결합하는 방식을 기반으로 한다. 이에 본 증례는 좁은 폭경의 하악 전치부에서 상부에 결합구조를 가진 일체형 미니 임플란트를 통하여 이러한 합병증을 줄이고자 하였으며 디지털 시스템을 이용하여 전반적인 치료기간을 단축하였다. 두명의 환자에서 유지기능과 심미적인 면에서 만족스러운 임상결과를 얻었기에 본 증례를 보고하고자 한다.
