Abstract

Objectives: To compare patient-reported experience between a Penn expander activated every other day vs twice daily.

Materials and methods: A total of 30 patients aged 12-16 years with transverse maxillary deficiency were recruited from the outpatient clinic, Faculty of Dentistry, Alexandria University (February 2019-December 2020). They were randomly allocated to two groups using block randomization (block size of six) and an allocation ratio of 1:1, which was concealed using opaque, sealed, sequentially numbered envelopes. Both groups received Penn expanders anchored by four palatal miniscrews. The slow maxillary expansion (SME) group activated the appliance once every other day. The rapid maxillary expansion (RME) group activated the appliance twice daily. Outcome measures were pain, pressure, headache, dizziness, speech difficulty, chewing difficulty, and swallowing difficulty scores rated by the participants on an 11-point numeric rating scale (NRS) at the following four time points: before appliance insertion (t1), after first activation (t2), after 1 week of activation (t3), and after last activation (t4).

Results: Data of 24 patients in the SME group (n = 12, mean age = 14.30 ± 1.37 years) and RME group (n = 12, mean age = 15.07 ± 1.59 years) were analyzed. Median scores for all outcomes were in the bottom quartiles of the NRS. No difference was found between the two groups at t1 or t2. Significantly higher scores for all variables, except dizziness and headache, were reported in the RME group at t4.

Conclusions: Activation of miniscrew-supported expanders resulted in mild to moderate discomfort and functional limitation. Slow activation resulted in a better overall patient experience compared with rapid activation.

青少年上颌缓慢扩张与快速微型螺钉支撑扩张的患者报告结果:随机临床试验的次要结果。
目的比较患者报告的隔天使用彭氏扩弓器与每天使用两次彭氏扩弓器的体验:从亚历山大大学牙科学院门诊部(2019 年 2 月至 2020 年 12 月)共招募了 30 名 12-16 岁的上颌骨横向缺损患者。他们被随机分配到两组,分配比例为 1:1,使用不透明、密封、按顺序编号的信封进行隐藏。两组均接受由四个腭小螺钉固定的宾氏扩弓器。慢速上颌扩弓(SME)组每隔一天使用一次矫治器。快速上颌扩弓器(RME)组每天使用两次。结果测量指标为疼痛、压力、头痛、头晕、言语困难、咀嚼困难和吞咽困难评分,由参与者在以下四个时间点用 11 分数字评分量表(NRS)进行评分:矫治器安装前(t1)、首次激活后(t2)、激活一周后(t3)和最后一次激活后(t4):分析了 SME 组(12 人,平均年龄为 14.30 ± 1.37 岁)和 RME 组(12 人,平均年龄为 15.07 ± 1.59 岁)24 名患者的数据。所有结果的中位数均位于 NRS 的下四分位数。在 t1 或 t2 阶段,两组之间未发现差异。除头晕和头痛外,RME 组在 t4 时的所有变量得分均显著高于其他组:结论:激活微型螺钉支撑扩张器会导致轻度至中度不适和功能限制。与快速激活相比,慢速激活会给患者带来更好的总体体验。
