沙特阿拉伯地区牙科学生、实习医生和刚毕业牙医对种植牙并发症的认知、意识和看法：基于网络的匿名调查。

BACKGROUND: It is necessary for dental students and freshly graduated dentists to apply their education and practice to different clinical and preclinical procedures. The implant success rate and durability are high. Therefore, this study was designed to assess the level of knowledge, awareness and perception of dental students, interns and freshly graduated students regarding dental implant complications in Saudi Arabia. METHODS: A cross-sectional study design using a web-based method was conducted at different dental institutions in Saudi Arabia from December 2019 to March 2020. Data were collected from all (n = 288) undergraduate students, interns and freshly graduated dentists using a pretested standardized self-administered web-based questionnaire that was prepared and circulated using a template provided by Google Forms (Google, Inc., USA). Descriptive statistics and chi-square tests were performed to analyse the data using SPSS (version 20). RESULTS: A total of 288 participants completed the questionnaire, with a response rate of 83.4%. Of the total participants, 37.5% showed a good level of knowledge regarding dental implant procedures, and 38.9% showed the same level of knowledge regarding implant complications. The most important cause of complications associated with dental implants was case selection, which accounted for 54.17%. Most participants (58.33%) chose massive bone loss related to implant failure as the most common late dental complication, while 26.39% chose postoperative infection as the most common early dental complication. In addition, 30.56% of the participants selected screw loosening as the most frequent mechanical complication. However, lack of implant primary stability was the most common hard-tissue implant complication. Based on aesthetic and reversible complications, restorations that were too buccal or too palatal and prosthetic-related, respectively, were the least common dental implant complications. CONCLUSIONS: The level of knowledge among participants regarding dental implant complications differed among the institutions participating in this study. This difference reflects a significant variation that necessitates reviewing and standardizing dental implant curricula among these institutions.

背景：对于牙科学生和刚毕业的牙医来说，将他们的教育和实践应用于不同的临床和临床前程序是必要的。种植体的成功率和耐用性都很高。因此，本研究旨在评估沙特阿拉伯牙科学生、实习医生和刚毕业的学生对牙科种植体并发症的知识、意识和看法。

方法：2019 年 12 月至 2020 年 3 月，在沙特阿拉伯的不同牙科机构采用基于网络的横断面研究设计。使用预测试的标准化自我管理网络问卷从所有（n=288）本科生、实习医生和刚毕业的牙医中收集数据，该问卷由 Google 表单（Google，Inc.，美国）提供的模板编写和分发。使用 SPSS（版本 20）进行描述性统计和卡方检验来分析数据。

结果：共有 288 名参与者完成了问卷，应答率为 83.4%。在总参与者中，37.5%对牙科种植程序表现出良好的知识水平，38.9%对种植并发症表现出相同的知识水平。与牙科植入物相关的并发症的最重要原因是病例选择，占 54.17%。大多数参与者（58.33%）选择与植入物失败相关的大量骨丢失作为最常见的晚期牙科并发症，而 26.39%选择术后感染作为最常见的早期牙科并发症。此外，30.56%的参与者选择螺丝松动作为最常见的机械并发症。然而，植入物初级稳定性不足是最常见的硬组织植入物并发症。基于美学和可逆性并发症，分别位于颊侧或腭侧过于突出以及与修复体相关的修复体是最不常见的牙科植入物并发症。

结论：参与本研究的机构中，参与者对牙科种植体并发症的知识水平存在差异。这种差异反映了显著的变化，需要对这些机构的牙科种植课程进行审查和标准化。
