작금의 급변하고 있는 치과 의료 시장 상황에서, 치과용 임플란트를 사용한 수복 치료는 이미 국민건강보험의 적용을 받을 정도로 대중적이고 보편적인 치료로자리매김하였다. 상실된 자연치를 대체하고자 하는고대로 부터의 아이디어가 단순한 시도가 아닌 범용으로 현실화 되는데 까지는 상당히 오랜 기간이 걸렸는데, 이는 티타늄(혹은 티타늄 합금)과 뼈 사이의 Osseointegration 현상의 발견을 통해서였다.
The restorative treatment using titanium implants has become a standard procedures in everyday clinical practice. However, there are several concerns about the use of titanium as a materials. Above all, the grayish metal color provokes esthetic problems when the soft tissue around the implants is not optimal. Recently, zirconia has been emerging as an alternative to titanium due to its white color and superior physicochemical properties. In this paper, the current findings about zirconia implants was reviewed based on the results from animal and clinical experiments. In addition, the immediate implantation protocols using the natural tooth form zirconia implants was introduced as a novel procedures and future perspectives were discussed.
