The purpose of this study was to evaluate patients' and orthodontists' perspectives on knowledge of techniques for reducing orthodontic treatment time and acceptance of these techniques.
A total of 200 individuals were interviewed and equally divided into two groups: orthodontist group (62 female and 38 male; mean age, 38.07 years) and patient group (52 female and 48 male; mean age, 22.61 years; in the active stage of fixed orthodontic treatment). One questionnaire for each group was administered, including questions about the duration of orthodontic treatment and techniques used for treatment optimization, such as corticotomy, distraction osteogenesis, vibration, and laser therapy. The associations between variables were analyzed by the χ test at a significance level of 5%.
Among orthodontists, 76% knew at least one technique to reduce the treatment duration, with corticotomy being the most frequently cited (66%); however, only 12% used one or more of these techniques. Laser therapy was the most frequently implemented technique (7%). Regarding the duration of orthodontic treatment, the mean time reported by orthodontists was 19 to 24 months, regardless of the technique or the experience of the orthodontist. Furthermore, 39% of patients expected their treatment to last for more than 24 months, with 50% accepting to undergo further procedures to reduce this duration.
Patients are willing to undergo additional procedures to reduce the treatment duration and to bear additional costs. However, despite their knowledge, orthodontists do not apply or offer these techniques to the patients.
本研究旨在评估患者和正畸医生对缩短正畸治疗时间的技术的了解程度和对这些技术的接受程度。
共对 200 人进行了访谈，将他们平均分为两组：正畸医生组（62 名女性和 38 名男性；平均年龄 38.07 岁）和患者组（52 名女性和 48 名男性；平均年龄 22.61 岁；处于固定正畸治疗的活跃阶段）。为每组分别设计了一份问卷，其中包括关于正畸治疗时间和用于优化治疗的技术（如皮质切开术、牵张成骨术、振动和激光治疗）的问题。采用 χ 检验分析变量之间的相关性，检验水准为 5%。
在正畸医生中，76%的人至少了解一种缩短治疗时间的技术，其中皮质切开术最为常见（66%）；然而，只有 12%的人使用了一种或多种这些技术。激光治疗是最常实施的技术（7%）。关于正畸治疗的持续时间，正畸医生报告的平均时间为 19 至 24 个月，无论使用何种技术或正畸医生的经验如何。此外，39%的患者期望治疗时间超过 24 个月，其中 50%愿意接受进一步的程序以缩短治疗时间。
患者愿意接受额外的程序来缩短治疗时间并承担额外的费用。然而，尽管正畸医生了解这些技术，但他们并没有向患者提供或应用这些技术。
