Abstract
목적: 발치와에 치조제 보존술을 시행한 부위에 식립한 임플란트의 일정 기간의 생존율을 초기고정 값과 방사선학적 계측을 통해 분석해보고자 하였다.
연구 재료 및 방법: 19명의 환자에 sandblasted, large-grit, acid-etched (SLA) 표면을 갖는 단일 제품의 21개의 임플란트를 조사하였다. 임플란트는 치조제 보존술(Alveolar ridge preservation technique: ARP) 시행 후 2 - 3개월의 치유 기간 후 식립 되었으며, 식립 시 및 보철 시행 전 Periotest value (PTV)와 식립 시 및 최종 점검시의 방사선 사진을 통한 Marginal bone level (MBL)의 변화를 측정하였다.
결과: 전체 임플란트의 생존율은 100%로 나타났고 식립 시의 PTV는 평균 -0.06 ± 8.33이었으며 보철 시행 전 PTV는 평균 -5.75 ± 1.72이었다. 근 원심 평균 MBL의 변화는 -0.55 mm에서 1.6 mm의 범위로 평균 0.19 ± 0.58 mm를 나타내었다.
결론: 발치와 보존술을 시행한 부위에 식립한 임플란트는 높은 생존율을 나타내며 안정적인 변연골 유지를 보이는 것으로 사료된다.
Purpose: The purpose of present study was to retrospectively analyze the survival rate of implant placed after alveolar ridge preservation by initial stability and radiographic measurements.
Materials and Methods: In total, 19 patients who received 21 sandblasted, large-grit, acid-etched (SLA) implants were enrolled in this retrospective study. Implants placed after alveolar ridge preservation technique (ARP) 2 - 3 months healing period, Periotest value (PTV) measured at implant placement and before placed prosthodontics. Marginal bone level (MBL) was measured at implant placement and final recall check.
Results: Overall survival rate of implant was 100%. Mean PTV at implant placement was -0.06 ± 8.33 and mean PTV before placed prosthodontics was -5.75 ± 1.72. The range of MBL change was from -0.55 mm to 1.6 mm (Mean: 0.19 ± 0.58 mm).
Conclusion: The findings of present study suggest that the implant paced after alveolar ridge preservation appear high survival rates and stable MBL.
