초록

임플란트 피개의치는 전통적인 총의치에 비해 높은 유지력 및 저작능력, 환자의 만족도를 보인다. 특히 골흡수가 심한 하악 무치악 환자의 치료에서는 우선되는 치료방법으로 고려된다. 임플란트 피개의치를 위한 attachment에는 임플란트간 연결된 bar type과 연결되어있지 않은 solitary type으로 구분할 수 있다. 최근 임상에서 많이 사용하는 solitary type의 경우 임플란트간의 평행관계가 중요하며, 임플란트간의 평행관계가 불량한 경우 attachment의 마모 및 유지력 감소로 유지관리를 내원횟수가 증가할 수 있다. 본 증례는 평행하지 못한 두 개의 하악 임플란트 식립 환자에서 milled bar를 이용하여 제작한 임플란트 피개의치로 만족할 만한 결과를 얻었기에 이를 보고하고자 한다.

Implant overdenture exhibits higher retention, masticatory function, and patient's satisfaction compared to conventional dentures. Particularly, in treatment of severe alveolar bone resorption, implant overdenture can be considered as the first treatment option. The types of attachments used for implant overdenture can be classified into solitary type, which implants are not connected to each other, and bar type in which implants are connected. In the case of solitary type commonly used in clinical practice, parallel relationship is important. When it is not established, there is a higher risk of attachment wear, retention loss, and frequent visits for maintenance. In this case, satisfactory results have been obtained with implant overdentures using milled bar on two unparallel implants placed on the mandible.
