무치악 환자에 있어서 골유착 임플란트는 통상의 다른 보철수복방법과 비교했을 때, 기능적으로나 환자의 만족도 면에 있어서 아주 좋은 결과를 보이며, 삶의 질 향상에도 가장 우수한 것으로 알려져 있다. 골질이 양호하고 골량이 충분한 부위에 외과적으로 많은 수의 임플란트를 적절히 식립하여, 최상의 임플란트 보철물 설계가 가능하게 배열되는 것이 바람직하나, 아직까지는 환자와 치과의사 모두에게 합병증과 여러 문제들이 한계로 남아 있다. 골유착에 관한 보철적인 문제, 즉 임플란트 실패, 보철물의 부적합, 임플란트 구성요소의 파절, 그리고 나사 풀림 등 합병증에 관해 분석하고 그에 관한 증례를 보고하고자 한다.
Abstract
Edentulous patients with a severely resorbed mandible or maxilla often experience problems with conventional dentures, such as insufficient stability and retention, together with a decrease in chewing ability. Because of the good prognosis of dental implants, these patients can be successfully treated with implant-retained or implant-supported prosthesis. Ideally, a maximum number of implants of maximum length are placed in appropriate surgically prepared sites that are surrounded by a maximum amount of bone of favorable quality. The implants are favorably aligned faciolingually and mesiodistally to enhance optimal prosthodontic design. This article describes the clinical problems and complications encountered when treating a consecutive number of edentulous patients with osseointegrated implant-supported prostheses.
