The aim of this study was to compare patients' overall perception of treatment with orthodontic mini implants placed in the maxillary anterior or posterior region. Twenty young adult patients were divided into 2 groups (n = 10). In group 1 (G1), mini implants were placed in the maxillary anterior midline just below the labial frenum. In group 2 (G2), mini implants were placed bilaterally in the maxillary posterior region, between the maxillary second premolar and first molar at the mucogingival junction. Questionnaires were used to record patient experiences with the mini implants at 3 time points: immediately after placement, 1 week after placement, and immediately after removal. Patients were offered 3 choices representing different levels of intensity. The patients were also asked to record their responses on a scale of 0 to 10 for each parameter evaluated. Each unit was subdivided into units of 10. A score of 0 indicated the best response and 10 indicated the worst response. Statistical analyses included the Student t and chi-square tests. Patients in G2 reported greater discomfort during mini implant placement than did patients in G1 (P = 0.036). During the following week, some patients experienced a bad taste at the site, rated significantly worse in G2 than in G1 (P = 0.043). There was also a statistically significant difference between the 2 groups (P = 0.032) in response to a question about the overall experience of the procedure, with G2 rating it better than G1; in the anterior region, the patients had a mean score of 2.00 (SD, 1.29; 95% CI, 0.22 to 3.78); and in the posterior region, they had a mean score of 0.00 (SD, 0.00; 95% CI, 0.81 to 3.19). There were no statistically significant differences in the distributions of responses for any measured outcome between G1 and G2. At mini implant removal, a greater number of patients in G2 than in G1 found the entire procedure to be somewhat different (unfamiliar) compared with other routine orthodontic procedures (P = 0.004). Despite the scores for the question on overall experience, the responses to questions about individual aspects of treatment indicated that patients with mini implants placed in the anterior region had a better experience than did patients with mini implants placed in the posterior region.
本研究旨在比较正畸微型种植体在前牙区或后牙区植入后患者对治疗的整体感受。将 20 名年轻成年患者分为 2 组（n=10）。在第 1 组（G1）中，微型种植体置于上唇系带下方的中线前牙区。在第 2 组（G2）中，微型种植体双侧植入上颌第二前磨牙和第一磨牙之间的牙槽黏膜交界处。使用问卷记录患者在 3 个时间点的微型种植体体验：植入后即刻、植入后 1 周和移除后即刻。患者有 3 种不同强度的选择。还要求患者对每个评估参数的 0 到 10 分进行评分。每个单位细分为 10 个单位。0 表示最佳反应，10 表示最差反应。统计分析包括学生 t 检验和卡方检验。G2 组患者在微型种植体植入过程中报告的不适程度高于 G1 组（P=0.036）。在接下来的一周内，一些患者在植入部位出现异味，G2 组的评分明显高于 G1 组（P=0.043）。在对手术整体体验的问题上，2 组之间也存在统计学差异（P=0.032），G2 组的评分好于 G1 组；在前牙区，患者的平均得分为 2.00（SD，1.29；95%CI，0.22 至 3.78）；在后牙区，他们的平均得分为 0.00（SD，0.00；95%CI，0.81 至 3.19）。在 G1 和 G2 之间，任何测量结果的反应分布均无统计学差异。在微型种植体取出时，与其他常规正畸治疗相比，G2 组中更多的患者发现整个过程有些不同（陌生）（P=0.004）。尽管整体体验问题的得分，但对治疗个别方面的问题的回答表明，在前牙区植入微型种植体的患者比在后牙区植入微型种植体的患者体验更好。
