초록

연구목적: 의치 접착제는 구강 내 의치 장착 시 유지에 도움을 주는 위해 사용되는 재료로써 의치상과 점막 사이에 계면력을 증가시켜 유지를 향상시킨다. 이에 본 실험은 의치 접착제의 유지력을 생체 외 실험으로 비교, 평가하는 것으로 실리콘 무치악 모형과 레진 의치상 간의 인장력을 측정하여 의치 접착제의 유지력을 비교, 평가하고 탈락력이 가해진 방향에 따른 유의성을 알아보고자 하였다. 연구 재료 및 방법: 두가지 의치 접착제로 POLIDENT$^{(R)}$와 COREGA$^{(R)}$를 사용하여 레진 의치상에 적용시키고, 실리콘 모형에 적합시킨 후 인스트론으로 인장력을 측정하였다. 인공타액으로 접착제의 농도를 점점 희석시켜 반복 측정하였고, 수직력, 측방력, 전후방력을 각각 측정하여 비교하였다. 결과:1. 인공타액만을 사용한 대조군과 비교시 의치 접착제를 사용한 군에서 유의성 있는 유지력 증가를 보였다 (P<.05). 2. 희석횟수에 따른 비교 시 두 접착제 군에서 모두 1회 희석 시에는 희석시키지 않은 군과 유의한 차이를 보이지 않았으나 2회, 3회, 4회 희석시킨 군과는 유의한 차이를 보였다 (P<.05). 3. 탈락 방향에 따른 비교 시 수직 방향의 탈락력이 가장 컸으며 전후방력, 측방력의 순으로 유의성 있는 차이를 보였다 (P<.05). 4. 두 접착제 간의 접착력은 유의성 있는 차이를 보이지 않았다. 결론: 이상의 결과에서 접착제의 사용은 유지력 증가에 유용한 것으로 나타났고, 특히 수직적으로 가해지는 힘에 저항력이 큰 것으로 나타났다.

Purpose: The purpose of this study was to compare the retention of the two denture adhesives with a silicone edentulous model and a resin denture base in vitro study. Material and methods: The experimental groups were used two denture adhesives and classified into 5 subgroups each. Subgroups were divided by the number of times the saliva sprayed. The control group was used synthetic saliva only. Dislodging tensile strengths were applied to the resin denture base using Instron in 3 directions ; vertical, lateral, and anterior-posterior. Results: The retention of two denture adhesives was increased significantly than saliva alone (P <.05). In each denture adhesives, the retention of saliva sprayed first was decreased than denture adhesive alone, but it didn't have significant differences. Whenever saliva sprayed repeated, the retention was decreased significantly than saliva sprayed first (P <.05). In each denture adhesives, vertical retentive force was highest than lateral and anterior-posterior retentive forces, and anterior-posterior retentive force was higher than lateral retentive force. This results were significantly different (P < .05). Significant differences of the retentive ability among two denture adhesives were not observed. Conclusion: From the results, use of the denture adhesives resulted in improved retentive ability of denture. Especially retentive force was highest in vertical direction.
