Abstract

Purpose: To evaluate the preferences of dental practitioners for tooth-supported crowns dental ceramics by means of an online survey and to assess the influence of age, gender, years of experience, and dental specialty on those preferences. Materials and Methods: An anonymous questionnaire was delivered online through Google Surveys, targeting 796 dentists. It contained 17 dichotomous, closed questions with two sections. The first section dealt with general characteristics, including age, gender, years of experience, training in prosthodontics, and hours worked per week. The second section included questions regarding preferences of different materials for crowns, and the use of digital workflows. Analyses were carried out with Stata 14.0 software (StataCorp, TX, USA). A significance level of p=0.05 was adopted. Results: 248 surveys were answered. Practitioners in Chile preferred lithium disilicate for the anterior region (55.2%) but also for the posterior area (40.7%), regardless of their age, gender, years since graduation, hours worked per week or any training in prosthodontics. Chilean dentists over 50 years old considered zirconia almost 4 times more than those under 30 years old for anterior crowns (51.85%). 59.68% of dentists take digital impressions, and 37.10% have access to chairside CAD/CAM technology. In this group, 54.4% preferred feldspathic ceramic for anterior and 23.9% for posterior crowns. Conclusions: While there is a wide range of dental ceramic materials, these results provide a snapshot of the current trends in Chile where lithium disilicate is the most preferred ceramic material for tooth-supported crowns, and metal-ceramic is the least preferred material.

智利牙科医生对牙冠陶瓷材料偏好的调查。
目的:通过在线调查评估牙科医生对牙齿支撑冠牙科陶瓷的偏好,并评估年龄、性别、工作年限和牙科专业对这些偏好的影响。材料与方法:通过 Google Surveys 在线发放匿名问卷,调查对象为 796 名牙科医生。问卷包含 17 个二元封闭式问题,分为两个部分。第一部分涉及一般特征,包括年龄、性别、工作年限、接受过的修复学培训以及每周工作时间。第二部分包括对不同牙冠材料的偏好以及数字化工作流程的使用情况。分析使用 Stata 14.0 软件(StataCorp,美国德克萨斯州)进行。显著性水平为 p=0.05。结果:共收到 248 份调查问卷。在智利,无论年龄、性别、毕业年限、每周工作时间或是否接受过修复学培训,牙医们都更倾向于在前牙区使用二硅酸锂(55.2%),但在后牙区也是如此(40.7%)。智利 50 岁以上的牙医在制作前牙牙冠时使用氧化锆的比例(51.85%)几乎是 30 岁以下牙医的 4 倍。59.68%的牙医使用数字印模,37.10%的牙医可以使用椅旁 CAD/CAM 技术。在这组牙医中,54.4%的人喜欢用长石陶瓷制作前牙冠,23.9%的人喜欢用长石陶瓷制作后牙冠。结论:虽然牙科陶瓷材料的种类繁多,但这些结果提供了智利当前趋势的一个缩影,即二硅酸锂是最受欢迎的牙冠陶瓷材料,而金属陶瓷是最不受欢迎的材料。
