This survey evaluated dentists' use of adhesive bonding methods of all-ceramic restorations over a period of twelve years. This is a follow-up survey which had been undertaken in 2007, 2011, and in 2015 [1].
A multiple choice questionnaire regarding adhesive bonding methods for all-ceramic restoration was developed and handed out in 2007 and 2019 to dentist participating in a local annual dental meeting in Northern Germany. The questionnaires were evaluated on the basis of evidence-based techniques from the scientific literature.
Data from 93 questionnaires (2019) were compared with 90 evaluated questionnaires from 2007. Bonding of oxide ceramic had improved over the years of observation (7% to 62%) whereas evidence-based bonding of silicate ceramic restorations decreased from 66% to 38%; common mistakes were using air abrasion on silicate surface. Females showed better values for correct adhesive cementation than males (f: 39-50%, m: 22%-41%). A correlation between correct cementation and years of professional experience could not be revealed.
Incorrect bonding of oxide ceramic restorations decreased within the 12 years investigated whereas there was no improvement of evidence-based bonding procedures of silicate ceramics. Still a high number of survey participants need additional training in bonding techniques.
本调查评估了牙医在十二年期间使用全瓷修复体的粘合方法的情况。这是一项后续调查，曾在 2007 年、2011 年和 2015 年进行过[1]。
针对全瓷修复体的粘合方法，我们开发了一份多项选择题问卷，并于 2007 年和 2019 年在德国北部举行的当地年度牙医会议上分发给牙医。问卷的评估依据是来自科学文献的循证技术。
将 2019 年的 93 份问卷数据与 2007 年的 90 份评估问卷进行了比较。在观察期间，氧化锆陶瓷的粘合情况有所改善（从 7%上升到 62%），而硅酸盐水陶瓷修复体的基于证据的粘合情况则从 66%下降到 38%；常见的错误是在硅酸盐水陶瓷表面使用喷砂。女性在正确的粘合方面比男性表现出更好的值（女性：39-50%，男性：22%-41%）。未能揭示正确的粘合与专业经验年限之间的相关性。
在调查的 12 年内，氧化锆陶瓷修复体的粘合不正确情况有所减少，而硅酸盐水陶瓷的基于证据的粘合程序则没有改善。仍有大量的调查参与者需要接受粘合技术方面的额外培训。
