During the coronavirus disease 2019 (COVID-19) pandemic, aerosol-generating procedures, including dental implant treatments, are considered high-risk. With dental implant treatment mostly an elective procedure, we aimed to assess whether the pandemic influenced patient selection, surgical procedures, and postoperative complications. We compared dental implant treatments during (March to December 2020) and before (December 2018 to February 2020) the COVID-19 pandemic based on patient and implant parameters, as well as postoperative complications. For analysis, we used the Chi-squared test with the Holm-Sidak correction for multiple comparisons. The number of implants placed during the COVID-19 pandemic (696 implants in 406 patients, 70 implants per month) was comparable to pre-pandemic levels (1204 implants in 616 patients, 80 implants per month). Regarding patient parameters, there were no significant differences in respiratory ( = 0.69) and cardiovascular conditions ( = 0.06), diabetes ( = 0.69), and smoking ( = 0.68). Regarding implant parameters, there was a significant difference in the distribution of augmentative procedures (no augmentation, guided bone regeneration, and sinus floor elevation, = 0.01), but no significant differences in the types of edentulous spaces ( = 0.19) and the timing of implant placement ( = 0.52). Regarding complications, there were significantly fewer minor complications ( < 0.001) and early (i.e., before loading) implant failures ( = 0.02) compared with pre-pandemic levels. Our results suggest that the COVID-19 pandemic had no effect on patient selection and only a slight effect on the surgical procedures. However, postoperative complications, including early failures, were significantly less prevalent during the pandemic.
在2019年冠状病毒病（COVID-19）大流行期间，包括牙种植治疗在内的产生气溶胶的操作被视为高风险操作。由于牙种植治疗大多是选择性手术，我们旨在评估大流行是否影响了患者选择、手术操作和术后并发症。我们根据患者和种植体参数以及术后并发症，比较了COVID-19大流行期间（2020年3月至12月）和之前（2018年12月至2020年2月）的牙种植治疗情况。为了进行分析，我们使用了经霍尔姆-西达克校正的卡方检验进行多重比较。COVID-19大流行期间植入的种植体数量（406例患者植入696颗种植体，每月70颗）与大流行前水平（616例患者植入1204颗种植体，每月80颗）相当。关于患者参数，呼吸系统疾病（ = 0.69）、心血管疾病（ = 0.06）、糖尿病（ = 0.69）和吸烟情况（ = 0.68）均无显著差异。关于种植体参数，增材手术的分布存在显著差异（无增材、引导骨再生和上颌窦底提升， = 0.01），但无牙间隙类型（ = 0.19）和种植体植入时间（ = 0.52）无显著差异。关于并发症，与大流行前水平相比，轻微并发症（ < 0.001）和早期（即加载前）种植体失败（ = 0.02）明显减少。我们的结果表明，COVID-19大流行对患者选择没有影响，对手术操作只有轻微影响。然而，在大流行期间，包括早期失败在内的术后并发症明显较少。
