Abstract
목적: 임플란트 표면의 특성과 임플란트 디자인은 성공적인 초기 고정을 얻는데 중요한 변수이다. 이 연구의 목적은 치유기간 동안 테이퍼드 직선형 디자인을 가진 SLA (Sandblasted and Acid-etched) 임플란트의 ISQ (Implant Stability Quotient) 값을 측정하고 임플란트의 안정성에 미치는 영향을 평가하는 것이다.
연구 재료 및 방법: 임플란트의 안정성을 측정하기 위하여 26명의 환자(여자 13명, 남자 13명)의 44개 임플란트에 대한 자기공명주파수분석(Resonance Frequency Analysis)을 실시하였다. 골질 및 골량에 대한 임상적 평가는 Lekholm & Zarb (1985)의 기준에 따라 시행하였다. 시간경과에 따른 임플란트 안정성변화(총 ISQ 값)를 고정체 식립 시 그리고 12 주후 치유지대주 연결 시 측정하고 RFA와 식립토크, RFA와 골질, RFA와 상, 하악골 사이의 상관관계를 평가하였다.
결과: 임플란트의 평균 ISQ값은 임플란트 식립 당시(기준선) 69.4 ± 10.2, 치유지대주연결에서(두번째수술) 81.4 ± 6.9였다(P < 0.05). RFA와 골질, RFA와 상하악골 사이에 유의한 차이가 있었다(P < 0.05). RFA와 식립토크, 식립부위, 고정체 직경, 임플란트 길이 사이에는 유의한 차이가 없었다(P > 0.05).
결론: 본 연구의 제한된 범위내에서 테이퍼드 직선형 디자인을 가진 SLA 임플란트의 ISQ값은 고정체 식립시와 치유지대주 연결 시 모두 높은 값을 보였다. 따라서 테이퍼드 직선형 디자인을 가진 SLA 임플란트는 초기안정성 및 2차 안정성을 향상시킬 수 있으며, 즉시 또는 초기하중을 적용할 수 있을것으로 사료된다.
Purpose: Implant surface modification and implant design are the principle targets for achieving successful primary stability. The aim of this study was to measure implant stability quotient (ISQ) values of sandblasted, large-grit, acid-etched (SLA) implants with tapered straight body design during the healing period, and to determine the various factors affecting implant stability.
Materials and Methods: To measure implant stability, resonance frequency analysis (RFA) was performed in 26 patients (13 women and 13 men) with 44 SLA implants with tapered straight body design. Implant stability (ISQ values) was evaluated at baseline and healing abutment connection (12 weeks), and the correlations between RFA and insertion torque (IT), bone quality, and jawbone were determined.
Results: The mean ISQ value of the implants was 69.4 ± 10.2 at the time of implant placement (baseline) and 81.4 ± 6.9 at the time of healing abutment connection (P < 0.05). Significant differences were found between RFA and bone quality and between RFA and jawbone (P < 0.05). No significant differences were found between RFA and IT, insertion area, fixture diameter, and implant length (P > 0.05).
Conclusion: ISQ values of SLA implants with tapered straight body design were high at baseline and healing abutment connection. It was concluded that SLA implants with tapered straight body design show improved primary and secondary stability, and that immediate or early loading may be applicable.
