Abstract

Recently implant supported single crown is the popular treatment option to replace a single missing tooth. The purpose of this retrospective study was to analyze and evaluate the survival of implants with the $TiUnite^{TM}$ surface for single tooth replacement. From September 2002 to December 2006, 269 TiUniteTM surfaced implants were used in single tooth replacements at the Institute of Oral Health Science, Samsung Medical Center. Twenty one cases were excluded because of neighbor implants, missing records & short follow up period. Among 248 implants, the 129 implants (52.0%) were inserted in the maxilla and 119 (48.0%) in the mandible. One hundred implants placement (40.3%) were combined with guided bone regeneration, and 36 implants placement (14.5%) were combined with sinus bone augmentation. Mean observation period was $26.0{\pm}11.8$ months after implant placement. Twelve implants were recorded as failures, rendering a single implant survival rate of 95.2% over the observation period. Among failed 12 implants, 10 implants placed in the maxilla. The survival rate in the maxilla was 92.2% and in the mandible was 98.3%. The use of $TiUnite^{TM}$ surfaced single implant placement showed high survival rate for short time period.

구강 내 단일 치아를 상실한 경우 기존에는 고정성 보철물을 이용하여 수복하는 방법이 일반적이었지만, 최근에 와서는 임플란트를 이용하여 수복하는 것이 보편화되고 있다. 본 연구는 단일 치아 결손 시 $TiUnite^{TM}$ 표면 처리한 임플란트를 이용하여 수복한 경우를 후향적으로 조사하여 그 생존율을 분석한 것이다. 2002년 9월부터 2006년 12월까지 삼성서울병원에서 단일 치아 결손 부위에 식립된 총 269개의 $TiUnite^{TM}$ 표면 처리한 임플란트 중 21개는 인접한 임플란트가 있거나, 기록이 누락되거나 관찰 기간이 짧아 연구에서 제외되었다. 248개의 임플란트 중 상악에는 129개(52.0%) 하악에는 119개(48.0%) 식립되었다. 수술 부위에 치조골 재생술을 시행한 경우는 총 100개(40.3%)였으며, 상악동 거상술이 시행된 증례는 총 36개(14.5%)였다. 수술 당일부터 관찰 기간은 평균 $26.0{\pm}11.8$ 개월이었으며, 그 기간 동안 실패한 것으로 간주된 임플란트는 12개로 생존율은 95.2%였다. 그 중 상악에서 실패한 경우가 10개, 하악에서는 2개로 각각의 생존율은 92.2%, 98.3% 이다. 단일 치아 결손 시 $TiUnite^{TM}$ 표면 처리한 임플란트를 이용하여 수복한 경우 단기간 동안 높은 생존율을 보였다.
