To compare the quality of complete dentures and quality of life of participants rehabilitated by using TENS (Transcutaneous electric nerve stimulation) facilitated impression making with manual impressions.
Ten completely edentulous participants were enrolled in the crossover, pilot study. Participants were randomized in 2 groups. Five participants in each group were rehabilitated by dentures fabricated with TENS facilitated definitive impression technique (group T) and conventional impression technique (group C). In group T, Bioelectric border molding was done for the participants, that uses electric stimulation of the nerves supplying the muscles. In group C, incremental border molding using modeling plastic impression compound was carried out. Participants in each group used the dentures for 3 months. After 3 months, OHIP-EDENT questionnaire responses were obtained from the participants to observe the oral health related quality of life. A dental specialist recorded denture quality by Kapur scoring criteria. After one month wash period, the treatment was swapped between the groups. OHIP-EDENT scores and Kapur score were recorded for the alternate dentures after 3 months of use. Descriptive analysis was followed by Mann Whitney test to compare the overall scores between group T and group C for OHIP-EDENT, the scores for individual domains of OHIP-EDENT, and Kapur score for denture evaluation (α = 0.05).
The overall OHIP-EDENT scores within each domain were less in group T when compared with the scores in group C and Kapur score for group T was more than group C. The difference was statistically significant i.e. = 0.002 & 0.003 respectively.
Less OHIP-EDENT scores in group T imply better perception of quality of life of individuals due to better performance of stomatognathic system. The higher Kapur scores in group T signifies better quality of dentures when TENS was used for definitive impression making.
比较使用经皮电刺激神经疗法（TENS）辅助印模制取与手工印模制取修复的全口义齿质量及参与者的生活质量。
十名全口无牙颌参与者纳入交叉性试点研究。参与者被随机分为两组。每组五名参与者分别采用TENS辅助终印模技术制作的义齿（T组）和传统印模技术制作的义齿（C组）进行修复。在T组中，对参与者进行生物电边缘整塑，即对支配肌肉的神经进行电刺激。在C组中，使用模型塑料印模膏进行递增式边缘整塑。每组参与者佩戴义齿3个月。3个月后，从参与者处获取OHIP-EDENT问卷回复，以观察口腔健康相关生活质量。一名牙科专家根据卡普尔评分标准记录义齿质量。经过一个月的洗脱期后，两组治疗方式互换。使用替代义齿3个月后，记录OHIP-EDENT评分和卡普尔评分。采用描述性分析，随后进行曼-惠特尼检验，以比较T组和C组在OHIP-EDENT总体评分、OHIP-EDENT各领域评分以及义齿评价卡普尔评分方面的差异（α = 0.05）。
与C组相比，T组各领域的OHIP-EDENT总体评分更低，且T组的卡普尔评分高于C组。差异具有统计学意义，分别为P = 0.002和P = 0.003。
T组较低的OHIP-EDENT评分意味着由于口颌系统功能更好，个体对生活质量的感知更佳。T组较高的卡普尔评分表明使用TENS进行终印模制取时义齿质量更好。
