Aim of this study was to get an overview of what dentists estimate to be the reason for failure of adhesive composite restorations and to gain knowledge about potential future foci for targeted further education. Therefore, a survey about the fabrication of composite restorations was conducted in the course of seven dental conferences with the main topic tooth-prevention. A total of 577 dentists participated in the survey. The most often called estimated factor for failure of composite restorations was the "dentist" (70.7%), followed by "indication" (32.2%), "material" (8.5%) and "patient" (8.1%). Participants estimated insufficient drying and fluid management (67.9%), incorrect application of the adhesive system (41.8%), insufficient lightpolymerisation (31.2%) and errors in incremental technique (27.6%) to be the main mistakes. The participating dentists claimed to attach great importance to careful drying and fluid management (60.8%), thorough adhesive application (37.3%), adequate incremental technique (32.6%) and sufficient lightpolymerisation (28.8%) while placing their own restorations. According to the survey participants, the treating dentist has the greatest influence on the quality and longevity of composite restorations. Drying and fluid management was the most often called estimated reason for failure but at the same time the step which is given the greatest caution.
本研究的目的是概述牙医认为复合树脂粘结修复失败的原因，并了解未来有针对性的继续教育的潜在重点。因此，在七个以牙齿预防为主题的牙科会议期间，开展了一项关于复合树脂修复体制作的调查。共有577名牙医参与了该调查。复合树脂修复失败最常被提及的估计因素是“牙医”（70.7%），其次是“适应证”（32.2%）、“材料”（8.5%）和“患者”（8.1%）。参与者认为干燥和液体管理不足（67.9%）、粘结系统应用不正确（41.8%）、光固化不足（31.2%）和分层技术错误（27.6%）是主要错误。参与调查的牙医声称，在进行自己的修复时，非常重视仔细的干燥和液体管理（60.8%）、彻底的粘结剂应用（37.3%）、适当的分层技术（32.6%）和足够的光固化（28.8%）。根据调查参与者的说法，治疗牙医对复合树脂修复的质量和寿命影响最大。干燥和液体管理是最常被提及的失败估计原因，但同时也是最谨慎对待的步骤。
