摘要
背景：正畸治疗有很多好处，但治疗时间延长会导致费用增加和后遗症。像压电切开术这样的压电辅助手术在加速治疗方面表现出了希望，尽管它们的功效尚未得到充分证实，也没有被广泛采用。本研究旨在评估压切术对正畸患者的疗效。方法：对16项随机对照试验（rct） 371例患者进行meta分析，比较压切术与常规正畸治疗的差异。系统检索PubMed、EMBASE和Cochrane图书馆数据库。统计分析包括使用随机效应模型的95%置信区间（CI）的平均差异（MD）。研究方案已在PROSPERO注册（CRD42022335350）。结果：与传统方法相比，压切术显著缩短了治疗时间（MD = -39.60,95% CI -59.67至-19.52），尽管只有一个研究组调查了总治疗时间。压切组治疗后疼痛在第1天显著升高（MD = 17.83,95% CI 5.75-29.92），但在第7天无显著差异（MD = 4.86,95% CI -0.74 - 10.47）。尽管第7天的疼痛程度相似，但患者表示更喜欢传统的正畸治疗。压切组在第一个月的Little's不规则指数降低率更有效（MD = 1.58,95% CI -0.13 ~ 3.29），在对线结束时无显著差异（MD = 1.04,95% CI -0.06 ~ 2.15）。结论：与常规方法相比，压切术可缩短正畸治疗时间。然而，考虑到研究的局限性和患者的偏好，未来需要更大的样本量和更多的随机对照试验来验证这些发现，并在广泛采用之前评估长期临床意义。
Effectiveness of piezoelectric-assisted orthodontic treatment : Systematic review and meta-analysis of randomized controlled trials.
Background: Orthodontic treatment offers numerous benefits, but prolonged treatment times can lead to increased costs and sequelae. Piezoelectric-assisted procedures like piezocision show promise in accelerating treatment, though their efficacy is not yet fully confirmed, nor are they widely adopted. This study aimed to evaluate the effectiveness of piezocision for orthodontic patients.
Methods: A meta-analysis of 16 randomized controlled trials (RCTs) involving 371 patients was conducted to compare piezocision with conventional orthodontic treatment. Systematic searches were performed in PubMed, EMBASE, and Cochrane Library databases. Statistical analyses included mean difference (MD) with 95% confidence intervals (CI) using a random-effects model. The study protocol was registered in PROSPERO (CRD42022335350).
Results: Piezocision significantly reduced treatment duration compared to conventional methods (MD = -39.60, 95% CI -59.67 to -19.52), though total treatment time was investigated by only one research group. Posttreatment pain was significantly higher in the piezocision group on day 1 (MD = 17.83, 95% CI 5.75-29.92) but showed no significant differences on day 7 (MD = 4.86, 95% CI -0.74 to 10.47). Despite similar pain levels by day 7, patients expressed preferences for conventional orthodontic treatment. The reduction rate of Little's irregularity index was more efficient in the piezocision group during the first month (MD = 1.58, 95% CI -0.13 to 3.29), with no significant differences at the end of alignment (MD = 1.04, 95% CI -0.06 to 2.15).
Conclusion: Piezocision resulted in reduced orthodontic treatment duration compared to conventional methods. However, considering the study limitations and patient preferences, future research with larger sample sizes and more RCTs is needed to validate these findings and assess the long-term clinical implications before widespread adoption.
期刊介绍：
The Journal of Orofacial Orthopedics provides orthodontists and dentists who are also actively interested in orthodontics, whether in university clinics or private practice, with highly authoritative and up-to-date information based on experimental and clinical research. The journal is one of the leading publications for the promulgation of the results of original work both in the areas of scientific and clinical orthodontics and related areas. All articles undergo peer review before publication. The German Society of Orthodontics (DGKFO) also publishes in the journal important communications, statements and announcements.
