Abstract

Implant-fixed prostheses and removable partial dentures are standard treatments for partially edentulous patients. Recently, implant-assisted removable partial dentures have become popular as a cost-effective and practical solution, especially for patients who cannot receive full-arch fixed prostheses. This method enhances retention, support, and stability, particularly in cases with few remaining teeth that are biomechanically disadvantaged. This case report presents a partially edentulous patient who had lost multiple teeth and implants in the maxilla and had an uneven occlusal plane. Considering the patient's general health and oral hygiene capability, the treatment plan was adjusted to avoid additional surgeries. Instead, the remaining teeth and Locator (Locator attachments, Zest Anchors LLC, Escondido, CA, USA) attachments were used to create an implant-supported removable partial denture. The Functionally Generated Path (FGP) technique was used to customize the occlusal surfaces of the artificial teeth. The outcomes were satisfactory for both the clinician and the patient, suggesting the effectiveness and practicality of this approach. This case highlights the potential benefits of these methods.

부분 무치악의 치료 시에는 고정성 임플란트 보철, 또는 가철성 국소의치로의 수복이 가능하다. 최근에는 전략적 위치에 임플란트를 식립하고, 이를 보조적으로 활용하는 임플란트 보조 국소의치 또한 많이 이용되고 있는데, 이러한 치료 방법은 전신 건강 및 비용 등의 문제로 고정성 보철이 어려운 환자에서 현실적인 대안이 될 수 있다. 또한 소수의 잔존치로 생역학적으로 불리한 경우에 임플란트를 적절히 활용하면 의치의 유지, 지지, 안정 세 요소를 보강할 수 있다. 본 증례의 환자는 상악에서 다수 치아와 임플란트를 상실한 부분 무치악 환자로 감소된 수직교합고경과 불균일한 교합평면이 관찰되었으며, 전신 건강과 구강위생관리 능력을 고려하여 추가 수술 없이 잔존 치아와 기존 임플란트를 이용한 임플란트 보조 국소의치로 치료하였다. 또한 최종 의치 제작 시 FGP technique을 이용하여 의치 인공치의 교합면을 개별 제작하였다. 치료 결과에 대해 술자와 환자 모두 만족하였기에, 본 증례를 보고하고자 한다.
