AIM
To investigate the cost-effectiveness of the novel CM-LOC attachment compared to the gold standard ball attachment in single implant mandibular overdenture.
MATERIAL AND METHODS
Fifty-two completely edentulous patients (50 to 69 years old) seeking to improve the retention of their complete mandibular dentures by installing a single implant in the midline of the mandible were recruited for this study. The patients were equally divided into two groups. The first group received a ball attachment abutment over the implant and the second group received CM-LOC attachment abutment. The initial cost and aftercare (maintenance) cost were calculated for each attachment and compared to each other.
RESULTS
The initial cost of the CM-LOC attachment was 2.2 times that of the traditional ball attachment. The after-care cost of the CM-LOC attachment was 2.39 times more than the ball attachment. The total cost of the CM-LOC attachment was 2.22 times that of the ball attachment.
CONCLUSION
The ball attachment system showed better cost-effectiveness compared to the CM-LOC attachment from the beginning of the study and throughout all the treatment period during the first year.
目的
研究新型CM-LOC附着体与金标准球帽附着体相比，应用于单颗种植体下颌覆盖义齿时的成本效益。
材料与方法
本研究招募了52例（年龄50至69岁）寻求通过在下颌中线植入单颗种植体来改善全下颌义齿固位的无牙颌患者。患者被平均分为两组。第一组在种植体上使用球帽附着体基台，第二组使用CM-LOC附着体基台。计算每种附着体的初始成本和后续护理（维护）成本，并相互比较。
结果
CM-LOC附着体的初始成本是传统球帽附着体的2.2倍。CM-LOC附着体的后续护理成本比球帽附着体高2.39倍。CM-LOC附着体的总成本是球帽附着体的2.22倍。
结论
从研究开始到第一年的整个治疗期间，球帽附着体系统相比CM-LOC附着体显示出更好的成本效益。
