有效的测量系统记录牙齿移动位移的生理应变的微妙范围内失踪。本文介绍了一种新型的牙齿松动度活体测量装置，并首次将其应用于临床，通过监测多托槽固定矫治器治疗后牙齿在固位过程中的松动度变化，对21例患者的牙齿松动度进行了活体测量（11名女性，10名男性;平均年龄16.1 +/- 3.1岁），用新型口内装置将上第一门齿向舌侧移位0.2 mm，持续0.2、0.5、1、2、5和10 s。测量结果直接记录后，多达2，7，14天和长达6个月后，矫治器脱粘。设备性能是精确和有效的，在临床使用。数据显示，显着的个体间不同的牙齿移动，这是非常高的头2天后，器具拆除。1周后，流动性值下降，但一般较高时，短期负荷相比，长期的。3个月后，牙齿松动度明显低于脱粘后。有趣的是，男性表现出显着的流动性比femines. We的工作是第一次使用体内测量设备能够执行和记录牙齿位移在这个微妙的范围内，并在这样的精度。此外，我们的研究结果阐明多托槽治疗后的牙齿流动性的变化，提供重要的信息保留periods.Establishment的这种新型的测量设备在临床上使用是一个重要的改进，当接近复杂的牙齿流动性在体内关于不同的问题，如牙周病，磨牙症。
Valid measurement systems recording tooth mobility upon displacement within the subtle range of physiological strains are missing. Here, we introduce a novel in vivo measurement device and demonstrate a first clinical application by monitoring tooth mobility changes during retention after fixed multibracket appliance therapy.Tooth mobility was measured in vivo on 21 patients (11 female, 10 male; mean age 16.1 +/- 3.1 years) by displacing the upper first incisor 0.2 mm lingually for 0.2, 0.5, 1, 2, 5, and 10 s with the novel intraoral device. Measurements were recorded directly after, as much as 2, 7, and 14 days and up to 6 months after appliance debonding.Device performance was precise and valid in clinical use. Data revealed significant interindividual varying tooth mobility, which was very high during the first 2 days after appliance removal. After 1 week, mobility values decreased, but were generally higher upon short loadings compared to long ones. After 3 months, tooth mobility was significantly lower than directly after debonding. Interestingly, males exhibited significantly less mobility than females.Our work is the first using an in vivo measurement device capable of performing and recording tooth displacements within this delicate range and in such precision. Furthermore, our findings elucidate tooth mobility changes after multibracket treatment, giving important information for retention periods.Establishment of this novel measurement device in clinical use is an important improvement when approaching the complexity of tooth mobility in vivo regarding different issues like orthodontics, periodontal disease, or bruxism.
