Evaluation of Effects of Five Orthodontic Adhesives in Clinical Applications andRelated Nursing Operations

摘要

By comparing the effects of five orthodontic adhesives in clinical applicationsand the effect of related nursing method on their performance, the authors found that the EB-type compound resin and the EM-type enamel adhesive are strongly affected by the nursing operation and temperature, with many factors affecting their setting. In addition, the support braces were found from clinical investigations to have a higher drop-out rate; therefore, the foregoing two adhesives proved to be ineffective in clinical applications. It is understood that photosetting adhesives are still in the research stage and have yet to be commercialized; thus, this kind of adhesive needs to be further studied. The performance index and clinical effects of the Beijing/Tianjing enamel adhesive and the CC-1 type orthodontic adhesive have been shown to be superior over those of the other three adhesives.
