AimThis nationwide population‐based cohort study aimed to assess the incidence of implant complication treatments, including implant removal procedures and peri‐implantitis treatments, in relation to implant surfaces and abutment types.MethodsData from the National Health Insurance Service, covering approximately 50 million individuals, were used. Implants and abutments were categorized by codes, including surfaces such as resorbable blasting media, sandblasted large grit and acid‐etched (SA) and hydroxyapatite coating, along with abutment structures (one‐piece straight, two‐piece straight, angled). The incidence of implant complication treatments was analysed using Kaplan–Meier curves and Cox proportional hazards regression (α = 0.05).ResultsThe study included 2,354,706 implants. The SA group had the lowest hazard ratio for implant removal procedures (p < 0.0001). No significant differences were found in the risk of peri‐implantitis treatments between implant surfaces (p = 0.0587). The risk of implant complication treatments did not differ significantly by the abutment type (p = 0.9542). The incidence rate of implant complication treatments was < 3.9 per 1000 implant‐years across all groups.ConclusionsThe SA group showed a slightly lower risk of late implant loss, whereas no significant association was found for the abutment type groups. All implant and abutment type groups showed an incidence rate of < 3.9 per 1000 implant‐years for complication treatments.

基于种植牙表面和基台类型的晚期种植体丢失和种植体周围炎的风险：一项针对老年人的全国性队列研究


目的这项全国性的基于人群的队列研究旨在评估与种植体表面和基台类型相关的种植体并发症治疗的发生率，包括种植体移除手术和种植体周围炎治疗。方法使用了来自国民健康保险公团的数据，涵盖大约 5000 万人。种植体和基台按代码分类，包括可吸收喷砂介质、喷砂大砂砾和酸蚀 （SA） 和羟基磷灰石涂层等表面，以及基台结构 （一体式直、两件式直、倾斜）。使用 Kaplan-Meier 曲线和 Cox 比例风险回归 （α = 0.05） 分析种植体并发症治疗的发生率。结果该研究包括 2,354,706 个植入物。SA 组种植体移除手术的风险比最低 （p < 0.0001）。在种植体表面之间，种植体周围炎治疗的风险没有显著差异 （p = 0.0587）。种植体并发症治疗的风险因基台类型没有显著差异 （p = 0.9542）。所有组种植体并发症治疗的发生率为 < 3.9/1000 种植体年。结论SA 组晚期种植体丢失的风险略低，而基台类型组未发现显著关联。所有种植体和基台类型组的并发症治疗发生率为 </1000 种植体年 3.9。
