Abstract

Compared with traditional full dentures, mandibular implant overdentures have the advantage in that good support and retention can be obtained even with two implants. When manufacturing a mandibular implant overdenture using two implants, it is important to place the implant in the correct position. The long-term prognosis of overdenture is good when two implants are placed in the direction vertical to the occlusal plane and parallel to each other at the canine position. However, it is difficult to place two implants in the correct position in edentulous patients, and if you use surgical guides in these cases, you can get help in placing the implants in a prosthetically advantageous position. This case, a 57-year-old male patient, came to our hospital with all upper and lower teeth removed due to periodontal disease. Therefore, the maxilla was restored with a traditional full denture and the mandible was restored with an implant overdenture using two implants, which resulted in satisfactory functional and esthetic results.

전통적인 총의치와 비교했을 때 하악 임플란트 피개의치는 2개의 임플란트로도 좋은 지지와 유지를 얻을 수 있다는 장점이 있다. 2개의 임플란트를 이용하여 하악 임플란트 피개의치를 제작할 때는 정확한 위치에 임플란트를 식립하는 것이 중요하다. 2개의 임플란트를 교합평면에 수직 방향으로, 견치 자리에 서로 평행하게 식립해야 피개의치의 장기적인 예후에 좋다. 하지만 무치악 환자에서 2개의 임플란트를 올바른 위치에 식립하는 것은 어려운 일이며, 이 때 서지컬 가이드를 이용한다면 보철적으로 유리한 위치에 임플란트를 식립하는데 도움을 받을 수 있다. 본 증례는 57세 남환으로 치주질환으로 인해 상, 하악의 모든 치아가 발거된 상태로 본원에 내원했다. 이에 상악은 전통적인 총의치, 하악은 2개의 임플란트를 이용한 임플란트 피개의치로 수복하여 기능 및 심미적으로 만족스러운 결과를 얻었으므로 이를 보고하고자 한다.
