義歯安定剤の接合力に及ぼす被着材の影響  [in Japanese] Effects of Adherend on Retentive Force Using Denture Adhesives and Home-reliners  [in Japanese]

本研究の目的は義歯安定剤の引張接合力に及ぼす被着体の影響を検討することである.被着体として口腔粘膜を擬似した寒天,金属床を擬似した金属板,アクリル板を用意した.市販の義歯安定剤である,粉末タイプ4製品,クリームタイプ4製品,テープタイプ2製品,クッションタイプ4製品の14製品について試験した.粉末タイプではアクリル,金属と比較して寒天との接合力は有意に小さい値を示した.クリームタイプでは被着体による接合力の違いは認められなかった.クッションタイプでは寒天<金属<アクリルと接合力が有意に大きくなった.テープタイプの接合力はクッションタイプと同じ傾向を示した.以上の結果より義歯安定剤の接合力は被着体によって異なることが明らかとなった.

This study evaluated the effects of adherends on retentive force (RF) using denture adhesives and home-reliners. Adherends of agar simulating oral mucosa, metal plates simulating metal base, and acrylic plates were prepared. Fourteen commercially available denture adhesive and home-reliner products consisting of four powder types, four cream types, two tape types and four cushion types, were examined. The RF to agar using the powder type was significantly smaller than those of the acrylic plate and the metal plate. The cream type did not significantly vary according adherends. Regarding the cushion type, the RF of the acrylic plate was significantly greater than those of the other adherends, and the RF of agar was significantly smaller than those of the others. The RFs using the tape type were similar to those of the cushion type. These results suggest that the RFs of denture adhesives and homereliners vary according to the adherends.
