초록

연구 목적: 부분 무치악 환자에서 Mg titanate implant (M Implant system, Shinhung, Korea)의보철 후 1년간의 방사선사진을 이용한 변연골 흡수량과 Osstell$^{(R)}$을 이용한 임플란트 안정성 평가 결과를 분석하여 임상적인 성공률에 대해 알아보고자 한다. 연구 재료 및 방법: 38명의 환자에 79개의 임플란트를 식립하여 보철 후 1년 동안 변연골 흡수량, 임플란트의 동요도, 임플란트 식립 위치에 따른 분포 및 성공률, 보철 전후에 따른 성공률을 분석했다. 결과: 변연골의 흡수량은 보철물 장착 후 1년간의 평가에서 상악에서는 평균 1.537 mm, 하악에서는 평균 1.172 mm의 변연골 흡수가 관찰되었으며, 전체적인 상하악의 평균 변연골 흡수량은 1.255 mm로 관찰되었다. 수술 후 시간이 경과함에 따라 ISQ값은 미약하게 감소하였다가 증가하는 경향을 보였으나, 상악과 하악 모두에서 식립 당일 이후 예비 인상일, 최종 보철물의 장착일과 주기적인 평가 기간 동안 ISQ값의 큰 증가나 감소를 나타내지는 않았다. 성공률은 상악에서의 94.12%였고, 하악에서의 98.39%였다. 결론: 본 실험의 결과로 미루어 Mg titanate implant는 임상적으로 양호한 결과를 보여주었다.

Purpose: This study examined the clinical success rate of Mg titanate implants (M Implant system, Shinhung, Korea), which employ a Mg coating method, by evaluating the marginal bone loss and implant stability using radiographs and Osstell$^{(R)}$, over a 1 year. Materials and methods: The locations of the implants placement were divided into 4 areas; the maxillary and mandibular premolars and molars. In the maxilla, 8 and 9 implants were inserted in the premolar and molar areas, respectively. In the mandible, 11 and 51 implants were inserted in the premolar and molar areas. Marginal bone loss and ISQ of all implants (79) were measured after insertion, mounting the prosthetic appliance, and 1, 3, 6, and 12 months after loading. The marginal bone loss was measured from the radiograph using XCP bite, which was customized, and the implant stability measured using Osstell$^{(R)}$. Fisher's exact test (${\alpha}$=.05) was used to compare the success rates of each region. Results: The mean marginal bone loss for the upper and lower jaws were 1.537 mm and 1.172 mm. The mobility showed a non-significant reduction or increase according with time. The success rates were accounted for 94.12% and 98.39% in the upper and lower jaws; the premolars and molars were accounted for 100% and 96.67%. The two cases of early failure resulted from failure of primary stability during implant insertion. The late failures were not observed for 1 year after adding a loading to the implants. Conclusion: The Mg titanate implant showed good primary stability and good clinical results in both healing and function.
