This paper reports data which helps identify changes and trends in the provision of indirect fixed prostheses in general dental practice in the UK. To determine by means of an anonymous, self-report questionnaire, the current trend in the provision of fixed prosthodontic treatments, with a special emphasis on the choice of treatment modalities, techniques and materials.
The data presented were extracted from the data obtained from a validated,121-question questionnaire distributed at random to general dental practitioners in the UK attending postgraduate meetings in 2015/2016, with a wide distribution of locations.
A response rate exceeding 66% was achieved. Amalgam and light-cured composite were the preferred material for core build-up of vital teeth for around 62% of the respondents. Dentine pins were still being used by 66% of the respondents. The vast majority of respondents (92%) used a post and core to restore root-treated teeth. Fibre posts were the most commonly used (63%) type of preformed post among the respondents. Using the opposing and adjacent teeth as a reference to control tooth structure reduction during vital tooth preparation was the most common method, used by 42% of the respondents. Addition-cured silicone impression materials were the most frequently used impression material (78%). The surveyed practitioners were equally split between precious and non-precious metals as the substructure for indirect restorations. Glass-ionomer luting cements (47%) and resin-based cements (52%) were the most commonly used to cement porcelain fused to metal and zirconia indirect restorations, respectively. Laboratory made aesthetic veneers were prescribed by half of the respondents, while a third of them preferred direct resin composite as a veneer material.
Within the limitations of the study, it was concluded that there has been an increase in the use of adhesive bonding and metal-free restorations. Amalgam and dentine pinscontinued to be used, contrary to international trends. Studies of the type reported are considered important in investigating trends and developments in dentistry.
本文报告的数据有助于确定英国普通牙科实践中间接固定义齿修复的变化和趋势。通过匿名自我报告问卷确定固定修复治疗的当前趋势，特别强调治疗方式、技术和材料的选择。
本文呈现的数据来自于 2015/2016 年在英国参加研究生会议的普通牙科医生随机分发的经过验证的 121 个问题问卷中提取的数据，地点分布广泛。
超过 66%的医生做出了回应。对于活髓牙的核构建，大约 62%的受访者首选银汞合金和光固化复合树脂作为材料。牙本质钉仍被 66%的受访者使用。绝大多数受访者（92%）使用桩核修复根管治疗后的牙齿。纤维桩是受访者中最常用的（63%）预制桩类型。42%的受访者使用邻牙和对颌牙作为参考来控制活髓牙预备过程中牙体结构的减少。加成型硅橡胶印模材料是最常用的印模材料（78%）。调查中的医生在间接修复的底层结构上，在贵金属和非贵金属之间平分秋色。玻璃离子水门汀（47%）和树脂基水门汀（52%）分别是最常用于黏结烤瓷熔附金属和氧化锆间接修复体的材料。一半的受访者开处方使用实验室制作的美学贴面，而三分之一的人更喜欢直接复合树脂作为贴面材料。
在研究的限制范围内，结论是，黏接和无金属修复的使用有所增加。银汞合金和牙本质钉的使用仍在继续，与国际趋势相反。报告的这种类型的研究被认为对于研究牙科学的趋势和发展很重要。
