PURPOSE
Two interforaminal dental implants in is a common treatment option for denture retention in edentulous patients. Economic methods to assess the patient's quality of life include the willingness to pay (WTP) for implant treatment and willingness to accept (WTA) to forgo implant treatment. The purpose of this study was to assess the monetary value of implant retained complete dentures using WTP and WTA.
METHODS
We included a convenience sample of 16 patients from a previously published cohort study on the survival of immediately loaded implants in edentulous patients to assess WTP and WTA for this treatment option.
RESULTS
The average maximum WTP for implant treatment was 4606 (95% CI: 2991-6222) Swiss Francs. Out of the 16 patients, only 5 were willing to trade their implants for money, with a mean WTA of CHF 33'500 (range: 3000-100'000).All patients would agree to undergo the implant surgery procedure again.
CONCLUSION
The results of the present study show that most patients are not willing to trade the increase in quality of life after implant surgery against money, suggesting that WTA exceeds by large WTP for the same health condition.
目的
在无牙颌患者中植入两枚椎间孔间牙种植体是义齿固位的常见治疗选择。评估患者生活质量的经济方法包括对种植治疗的支付意愿（WTP）和放弃种植治疗的接受意愿（WTA）。本研究的目的是使用WTP和WTA评估种植体固位全口义齿的货币价值。
方法
我们纳入了一个便利样本，该样本来自之前发表的一项关于无牙颌患者即刻负重种植体存活率的队列研究中的16名患者，以评估他们对这种治疗选择的WTP和WTA。
结果
种植治疗的平均最大WTP为4606（95%CI：2991 - 6222）瑞士法郎。在这16名患者中，只有5人愿意用他们的种植体换取金钱，平均WTA为33500瑞士法郎（范围：3000 - 100000）。所有患者都同意再次接受种植手术。
结论
本研究结果表明，大多数患者不愿意用种植手术后生活质量的提高来换取金钱，这表明在相同健康状况下，WTA大大超过WTP。
