研究了在丙烯酸树脂板中掺入CaF2（2.04%）、NaF（2.27%）和氟化胺（0.71%）对合成唾液中冲洗和浸泡的弯曲强度和氟化物释放量的影响。抗弯强度分别降低6.7%、9.5%和20%。氟化物从含NaF的板中释放最多，从含CaF2的板中释放时间最长，可能与化合物的溶解度有关。结果表明，AmF化合物的有机分子对亚克力板的强度影响最为显著。在体外冲洗实验中释放的F-浓度可以假定在体内由于牙科器具的较大尺寸而以较高的水平发生。
The effect of incorporated CaF2 (2.04%), NaF (2.27%) and amine fluoride (0.71%) in acrylic resin plates, on bending strength and fluoride release by rinsing and immersion in synthetic saliva, was determined. Bending strength was reduced by 6.7, 9.5 and 20% respectively. The most elevated release of fluoride from the NaF containing--and the most protracted from the CaF2 containing--plates may be related to the solubilities of the compounds. It appears that the organic molecule of the AmF compound affects the strength of the acrylic plates most significantly. The F- concentrations released in the in vitro rinsing experiment may be presumed to occur in vivo at some higher level due to the larger size of dental appliances.
