초록
통상적인 임플란트 치료는 식립 후 약 3 - 5개월 뒤 임플란트 상부 보철물을 제작한다. 이러한 치료과정의 단점으로는 환자가 임플란트 식립 후 보철물이 장착되는 최종 치료 시점까지의 기간 동안 유지력과 저작능력이 떨어지는 임시의치를 사용하여 생활해야 한다는 것이다. 최근의 임플란트 식립 후 즉시 부하 보철물 치료는 시술 적응증에 따른 제한이 있긴 하지만, 잦은 치과 방문이 어렵고 진료에 대한 협조도가 낮은 정신적, 신체적 장애 환자들에게 더욱 유용하다고 생각된다. 본 증례에서는 삼차원 컴퓨터 유도 수술법을 이용한 임플란트 식립 후 즉시 부하 보철치료를 정신지체장애 환자에서 시행하였으며, 시술 후 좋은 경과를 보였기에 이를 보고하는 바이다.
Abstract
Brånemark’s original protocol required 4 to 6 months for implant osseointegration before placement of the definitive prosthesis. Although this approach gave very predictable results, it had certain drawbacks. The main disadvantages of this approach wereprolonged treatment time, two surgical procedures, placement of a removable prosthesis that required modifications during the course of treatment, and a greater number of appointments. Immediate implant loading is a viable treatment method for selected cases. One of the greatest advantages of this method is the virtual surgery, which precedes the actual clinical treatment and eliminates any need for last minute decisions. The actual surgery time is decreased, since all steps are predetermined. These advantages aren’t only more useful for normal patients but also for the mental retardation patients whose cooperation is difficult. This article presents a clinical approach made possible due to the guided implant surgery and CAD/CAM technique.
