On 2 monkeys, adhesive fillings with Concise, using the Enamel Bond technique were made on 8 permanent and 12 deciduous teeth. A clinical check about 1 year later showed good results in the permanent dentition while the results in deciduous teeth were varied (loss of substance, pigmentations). The examination of marginal fit by aniline blue and a vacuum technique showed that in permanent teeth, 87.5% were impermeable, in deciduous teeth only 25%. Examination in the REM showed a perfect adaptation of the filling material to the enamel at the margins, while cohesion fractures were found within the material. The surface of the material was found to be rough after functional use. The bad results in deciduous teeth is explained by the thinness of the enamel in the experimental animal and by its parafunctioning. It is deduced that adhesive fillings are stable and impermeable after 1 year, provided there is no functional abrasion possible. The results should be confirmed by further, longerlasting experiments
在2只猴子身上,采用釉质粘结技术用Concise材料制作了粘结性充填物,分别用于8颗恒牙和12颗乳牙。大约1年后的临床检查显示,恒牙的治疗效果良好,而乳牙的效果则各不相同(物质流失、色素沉着)。通过苯胺蓝和真空技术对边缘密合性进行检查发现,恒牙中87.5%的充填物无渗漏,乳牙中只有25%无渗漏。扫描电镜检查显示,充填材料在边缘处与釉质完美贴合,而材料内部发现有粘结性断裂。经功能使用后发现材料表面粗糙。乳牙治疗效果不佳的原因是实验动物的釉质较薄及其存在功能异常。推断如果没有可能的功能磨损,粘结性充填物在1年后是稳定且无渗漏的。结果应通过进一步的、持续时间更长的实验来证实
