  • 보철물이 제기능을 발휘하기 위해서는 건강한 치주조직이 필요할 분 아니라, 보철물 그 자체가 건강한 치주조직을 계속적으로 유지시켜 줄 수 있어야 한다. 보철물이 치주질환을 야기하거나, 치주질환을 가진 지대치에 아무런 처치없이 보철물을 장착한다면 결국 치아의 상실을 초래하게 된다. 이런 일로 인하여 외국에서는 치과이사와 환자가 소송에까지 이르게 되는 불행한 에가 많다. 이런 예는 먼 나라의 이야기가 아니라, 우리 나라에서도 문제가 되어가고 있는 것 같다. 필자의 조사(미 발표)에 의하면, 보철물이 치주조직에 미치는 영향에 관하여 재 조명이 있어야 될것으로 생각한다.

  • All-on-six concept can be used as one of the treatment options to maximize the use of available residual alveolar bone for implant-supported fixed prosthesis on edentulous patients. But this process is complex and cumbersome. Digital system can be used at multiple steps, from implantation to prosthetic restoration, to overcome this shortcoming. In this case of a maxillary edentulous patient aged 76, digital system was used for restoration of 1-piece design, screw retained fixed prosthesis from diagnosis, implant surgery to fabrication of provisional and final prosthesis. For preoperative diagnosis and treatment planning stage, intra-oral information of a patient was digitalized by direct intra-oral scan. Surgical guide and immediate provisional prosthesis was designed based on this digitalized data. Patient's inconvenience was minimized by applying immediate provisional prosthesis, which was delicately fabricated according to the location data of six implants on most suitable residual alveolar bone. Then, final prosthesis was designed and fabricated going through new interim prosthesis which was newly designed and fabricated, considering patient's requests, stable vertical dimension and occlusion, and esthetic factors using digital system. We hereby report a case successfully applying digital system to multiple steps including implant surgery to fabricating prosthesis, to simplify existing complicated implant treatment procedure to an edentulous patient.
