ObjectiveDental implants are a considerable financial burden for elderly people and their caregivers. This study aimed to calculate the estimated economic costs of dental implants on the Korean older population.Materials and MethodsThe economic costs of dental implants for adults aged 75 years and older were estimated from a societal perspective, considering both direct and indirect expenditures. We used data from the Korean National Health Insurance Service for the period 2015–2018 to estimate the medical costs. Noninsured medical costs were estimated from research on medical expenses by the National Health Insurance Review and Assessment Service. Indirect costs related to transportation fees and time loss were obtained. The Cochran Armitage trend test was performed to examine the trend of the economic burden of dental implants.ResultsThe estimated economic costs showed from 2015 to 2018 (total costs: $26.54–55.66 million, total costs after discount: $17.11–39.56 million). Direct costs, including insured and noninsured medical costs, represented from $25.81 to $47.03 million. Indirect costs, including transportation and time costs, ranged from $0.73 to $1.63 million. The impact of the total dental implant costs was 0.0018%–0.0034% of the Korean annual gross domestic product and 1.03%–1.59% of the annual total costs of dental care benefits.ConclusionsThe estimated economic burden of dental implants significantly increased from 2015 to 2018 in older South Korean adults. These results will provide a foundation and guidance for further health economic studies on the burden of dental implants in the elderly population.

2015-2018 年韩国老年人种植牙的预计经济成本


目的牙种植体对老年人及其护理人员来说是相当大的经济负担。本研究旨在计算韩国老年人口种植牙的估计经济成本。材料和方法从社会角度估计75岁及以上成年人种植牙的经济成本，考虑直接和间接支出。我们使用韩国国民健康保险公团 2015 年至 2018 年期间的数据来估算医疗费用。非保险医疗费用是根据国民健康保险审查评估院对医疗费用的研究估算得出的。获得与运输费和时间损失相关的间接成本。采用Cochran Armitage趋势检验来检验种植牙经济负担的趋势。结果显示2015年至2018年的预计经济成本（总成本：2654-5566万美元，折现后总成本：1711-3956万美元）。直接费用，包括保险和非保险医疗费用，从 25.81 美元到 4703 万美元不等。包括运输和时间成本在内的间接成本从 0.73 美元到 163 万美元不等。种植牙总成本的影响占韩国年度国内生产总值的0.0018%–0.0034%，占年度牙科护理福利总成本的1.03%–1.59%。 结论 2015年至2018年种植牙的估计经济负担显着增加韩国老年人中。这些结果将为进一步研究老年人口种植牙负担提供基础和指导。
