The aim of this retrospective clinical study was to determine if there is a reduction in the overall treatment duration in orthodontic patients using low-intensity pulsed ultrasound (LIPUS) and Invisalign SmartTrack® clear aligners. Data were collected from the first thirty-four patients (9 males, 25 females; average age 41.37 ± 15.02) who finished their orthodontic treatment using an intraoral LIPUS device and Invisalign clear aligners in a private clinic. The LIPUS parameters used by patients at home for 20 min/day were: ultrasonic frequency 1.5 MHz, pulse duration 200µs, pulse repetition rate 1 kHz, and spatial average-temporal average intensity 30mW/cm. A control group (11 males, 23 females; average age 31.36 ± 14.41) matching for the same malocclusions was randomly selected from finished treatment cases of the same clinician. The date of first Invisalign attachment placement and first use of LIPUS application was recorded as T0, and the date of retainer delivery was recorded as T1. The treatment duration (T1-T0) and treatment reduction percentage with LIPUS device were collected and analyzed using two-sample t-test in Microsoft Excel. Treatment duration was significantly reduced in the LIPUS group (541.44 ± 192.23 days) compared to control group (1061.05 ± 455.64 days) ( < 0.05). The LIPUS group showed on average 49% reduction in the overall treatment time as compared to the control group. The average compliance of the patients using LIPUS was 66.02%. Patients who used LIPUS showed a clinically significant reduction in the overall orthodontic treatment duration compared to the control group who used Invisalign clear aligners only.
这项回顾性临床研究的目的是确定使用低强度脉冲超声（LIPUS）和隐适美SmartTrack®透明矫治器的正畸患者的总体治疗时间是否会缩短。数据收集自一家私人诊所中使用口内LIPUS设备和隐适美透明矫治器完成正畸治疗的前34名患者（9名男性，25名女性；平均年龄41.37±15.02岁）。患者在家中每天使用20分钟的LIPUS参数为：超声频率1.5MHz，脉冲持续时间200µs，脉冲重复频率1kHz，空间平均-时间平均强度30mW/cm²。从同一位临床医生的完成治疗病例中随机选取一组匹配相同错颌畸形的对照组（11名男性，23名女性；平均年龄31.36±14.41岁）。首次佩戴隐适美附件和首次使用LIPUS的日期记录为T0，佩戴保持器的日期记录为T1。使用Microsoft Excel中的两样本t检验收集并分析使用LIPUS设备的治疗时间（T1 - T0）和治疗时间缩短百分比。与对照组（1061.05±455.64天）相比，LIPUS组的治疗时间显著缩短（541.44±192.23天）（P<0.05）。与对照组相比，LIPUS组的总体治疗时间平均缩短了49%。使用LIPUS的患者平均依从性为66.02%。与仅使用隐适美透明矫治器的对照组相比，使用LIPUS的患者在正畸总体治疗时间上有临床显著缩短。
