Oral health in Canada and most developed and developing countries is funded by private payers, whose acceptance of treatment depends on their valuation of it. This study aims to determine how dentate individuals in Quebec, Canada, would value the benefits of mandibular two-implant overdentures based on their willingness to pay (WTP) for the treatment, either directly or with insurance/government coverage.
A total of 39 individuals (23-54 years) completed a Web-based WTP survey that consisted of three cost scenarios: (a) out-of-pocket payment; (b) private dental insurance coverage; and (c) public funding through additional taxes. Variations in WTP amounts were measured using regression models.
Among respondents who were dentate or missing some teeth, average WTP out of pocket for implant overdentures was CAD$5419 for a 90% success rate. They were willing to pay an average CAD$169 as one-time payment for private dental insurance, with a one in five chance of becoming edentate. WTP amounts increased substantially with the probability of success of implant overdenture therapy. The results of regression analyses were consistent with theoretical predictions for education level and income (P < 0.05).
The results of this study, within its limitations, suggest that dentate individuals would be willing to pay a significant amount to receive mandibular two-implant overdentures if and when they become edentate.
加拿大以及大多数发达国家和发展中国家的口腔健康由私人支付者提供资金,他们对治疗的接受程度取决于其对治疗的估值。本研究旨在根据加拿大魁北克省有牙列的个体直接支付或通过保险/政府承保为下颌双种植体覆盖义齿治疗支付费用的意愿,来确定他们对该治疗益处的估值。
共有39名年龄在23至54岁之间的个体完成了一项基于网络的支付意愿调查,该调查包括三种成本情景:(a)自付费用;(b)私人牙科保险承保;(c)通过额外税收进行公共资金支持。使用回归模型测量支付意愿金额的变化。
在有牙列或缺失部分牙齿的受访者中,种植覆盖义齿成功率为90%时,自付费用的平均支付意愿为5419加元。他们愿意一次性支付平均169加元购买私人牙科保险,有五分之一的概率会无牙。种植覆盖义齿治疗成功的概率越高,支付意愿金额大幅增加。回归分析结果与教育水平和收入的理论预测一致(P < 0.05)。
本研究结果在其局限性范围内表明,有牙列的个体如果或当他们无牙时,愿意支付大量费用来接受下颌双种植体覆盖义齿治疗。
