Abstract
[한글]

임플란트는 교합압에 의해 주위 골조직 파괴가 일어나지 않도록 설계하는 것이 중요하다.

Epoxy resin plate 모형상에 6개의 골내 임플란트(K·L blade, F·D·B·Ⅰ-Ⅱ형, F·D·B·Ⅰ-21형, 형상기억 합금 blade 및 2개의 Apaceram)를 후방지대치로 하고 하악 제이소구치 금속모형을 전방지대치로 계속가공의치를 제작하여 수직하중에 대한 임플란트와

지대치주위에 발생하는 음력을 Circular transmission polariscope를 통해 2차원적으로 비교 관찰하여 다음과 같은 결론을 얻었다.

1. 모든 경우에서 임플란트에 비해 치근단에 더 큰 응력이 나타났다.

2. 모든 blade는 근심부보다 원심부에 큰 응력이 나타났다.

3. F·D·B·Ⅰ-Ⅱ형이 21형보다 큰 응력이 나타났다.

4. 실험대상중 형상기억합금 blade의 응력분산 효과가 가장 좋았다.

5. Apaceram의 경우 blade보다 큰 응력이 나타났으며, rubber ring을 삽입한 경우 distal tipping을 나타냈다.

The purpose of this experimental study was to analyze the stress distribution from fixed partial dentures to the surrounding structures.

This study was carried out on the experimental bridges with K-L blade, F.D.B.Ⅰ-Ⅱ type, F.D.B.Ⅰ-21 type, shape-memory metal blade and two-Apacerams as posterior abutment.

The stress patterns and fringes were observed through the circular transmission polariscope.

The results of this study were obtained as follows:

1. The stress was more concentrated to the roots apex than the implants.

2. In all blade implants, the stress was more concentrated to the distal side than the mesial side.

3. F.D.B.Ⅰ-Ⅱ type was more stress concentrated than the 21 type.

4. Shape-memory metal blade was the most effective for stress distribution.

5. Apacerams were more stress concentrated than the blade types and in the model of Apaceram with rubber-ring, anterior root was tipped distally.
