虽然人们认为功能生成路径（FGP）技术的实现可以促进修复体咬合面设计，但尚未客观地将其与传统制造方法进行比较。因此，本研究采用t扫描进行单盲交叉临床试验，比较采用FGP技术（FGP）、平均值FGP技术（AVR）和常规制作（CON）设计的单个后牙人工冠的咬合时间（OT）和脱牙时间（DT）的变化。根据计算机生成的随机列表，10名参与者中的每一位都以不同的顺序尝试了三种人工冠。结果客观显示，FGP患者OT和DT的变化明显小于CON (P < 0.05)， AVR患者OT和DT的变化明显小于CON （P < 0.05）。FGP组和AVR组的主观反馈和调整咬合时间均优于CON组（P < 0.05）。没有对参与者造成伤害。总的来说，FGP是一种有效的技术，与发音系统的生理关系更加和谐。
Although it is believed that implementation of the functional generated path (FGP) technique can facilitate occlusal surface design for restorations, it has not been objectively comparedin situwith the conventional fabrication yet. Therefore, in the present study, a single-blind crossover clinical trial was conducted using T-scan to compare changes in occlusion time (OT) and disocclusion time (DT) of single posterior artificial crowns designed differently using FGP technique (FGP), average-value FGP technique (AVR) and conventional fabrication (CON). Each of the 10 participants took part in the study tried three artificial crowns in different sequences according to a computer generated randomization list. The results objectively revealed that changes in OT and DT were significantly smaller for FGP than CON (P < 0.05) and considerably smaller for AVR than CON, respectively. The subjective feedback and the occlusal adjusting time were better and shorter for FGP and AVR than CON (P < 0.05). No harm to the participants occurred. Overall, FGP is an efficient technique showing more physiological harmonious relationship with the articulating system.
