연구 목적: 이 연구의 목적은 임플란트의 직경, 길이 및 디자인의 변화가 임플란트 안정성 지수에 미치는 영향을 비교하는 것이다. 연구 재료 및 방법: 골질차이에 의한 변수를 제거하기 위해 상악골 평균밀도와 유사한 균일한(0.48g /cm3) 밀도를 가진 Polyuretane foam blocks (Sawbones, Pacific Research Laboratories Inc, Vashon, Washington)을 이용, 임플란트(Implantium, Dentium, Seoul, Korea)를 다양한 직경(∅3.8, ∅4.3 및∅4.8)과 길이(8, 10 및 12 mm)로 식립하여 그 변화가 임플란트 안정성 지수(Implant Stability Quotient, ISQ)에 미치는 영향을 비교하였다. 또 같은 직경과 길이(∅4.3 × 10 mm)에서 submerged와 non-submerged (SimplelineII, Dentium, Seoul, Korea) 디자인이 ISQ 에 미치는 영향을 비교하였다. 식립 회전력의 영향을 배제하기 위해 동일한 35 N의 Torque로 각 실험군당 10개씩 총 60개의 임플란트를 식립하였다. Osstell™ mentor(Integration Diagnostic AB, Sweden)를 이용하여 공진주파수를 측정한 후 ISQ 값으로 기록하였고, 그 결과를one-way ANOVA와 Tukey HSD test로 분석하였다(α=.05). 결과: 1. 임플란트 직경의 변화는 ISQ에 영향을 미치지 않았으나(P>.05), 임플란트 길이가 증가함에 따라 ISQ도 증가하였다(P<.001). 2. 임플란트 디자인의 변화는 ISQ와 유의한 상관관계를 보여Submerged 디자인의 ISQ가non-submerged 디자인보다 높게 나타났다(P<.05). 결론:임플란트 안정성을 높이기 위해서는 가능한 길이가 긴 임플란트를 식립하는 것이 유리하며, 같은 길이의 임플란트에서 볼 때 Non-submerged 디자인보다 submerged 디자인이 더 높은 ISQ를 얻을 수 있을 것으로 생각된다.
Abstract
Purpose: The purpose of this study is to ascertain the stability of the implant by comparing the effects of the change of implant diameter, length and design on implant stability quotient. Materials and methods: To remove the variable due to the difference of bone quality, the uniform density (0.48 g/cm3) Polyuretane foam blocks (Sawbones, Pacific Research Laboratories Inc, Vashon, Washington) were used. Implants (Implantium, Dentium, Seoul, Korea) were placed with varying diameters (∅3.8, ∅4.3 and ∅4.8) and length (8 mm, 10 mm and 12 mm), to assess the effect on implant stability index (ISQ). Also the influence of the design of the submerged and the non-submerged (SimplelineII, Dentium, Seoul, Korea) on ISQ was evaluated. To exclude the influence of insertion torque, a total of 60 implants (n = 10) were placed with same torque to 35 N. Using OsstellTM mentor (Integration Diagnostic AB, Sweden) ISQ values were recorded after measuring the resonant frequency, one-way ANOVA and Tukey HSD test results were analyzed. (α=0.05). Results: 1. The change of the diameter of the implant did not affect the ISQ (P>.05), but the increase of implant length increased the ISQ(P<.001). 2. The change in implant design were correlated with the ISQ, and the ISQ of submerged design was significantly higher than that of the non-submerged design(P<.05). Conclusion: In order to increase implant stability, the longer implant is better to be selected, and on the same length of implant, submerged design is thought to be able to get a higher ISQ than the non-submerged.
