To compare the acceptability and effectiveness of topical and infiltration anesthesia for placement of mini-implants used as temporary anchorage devices.
The sample comprised 40 patients, 17 males and 23 females, whose mean age was of 26 years and who were all undergoing orthodontic treatment and in need for anchorage reinforcement. Mini-implants were bilaterally placed in the maxilla of all individuals, with infiltration anesthesia on one side and topical anesthesia on the other. These 40 patients completed two questionnaires, one before and another after mini-implant placement, and pain was measured through a visual analog scale (VAS). The data collected were analyzed using descriptive statistics and the measurements of pain were compared by means of Mann-Whitney non-parametric test.
It was found that 60% of patients felt more comfortable with the use of topical anesthesia for mini-implant placement; 72.5% of patients described the presence of pressure during placement of the anchorage device as the most unpleasant sensation of the entire process; 62.5% of patients felt more pain with the use of topical anesthesia.
It was concluded that patients had less pain with the use of infiltration anesthesia, and also preferred this type of anesthetic.
比较局部麻醉和浸润麻醉在植入用作临时支抗装置的微型种植体时的可接受性和有效性。
样本包括40名患者，其中男性17名，女性23名，平均年龄26岁，均正在接受正畸治疗且需要加强支抗。在所有个体的上颌双侧植入微型种植体，一侧采用浸润麻醉，另一侧采用局部麻醉。这40名患者在微型种植体植入前和植入后分别完成两份问卷，并通过视觉模拟量表（VAS）测量疼痛程度。收集的数据采用描述性统计进行分析，疼痛测量结果通过曼-惠特尼非参数检验进行比较。
发现60%的患者在植入微型种植体时使用局部麻醉感觉更舒适；72.5%的患者表示在植入支抗装置过程中感受到的压力是整个过程中最不愉快的感觉；62.5%的患者在使用局部麻醉时感觉更疼痛。
得出的结论是，患者使用浸润麻醉时疼痛较轻，并且也更喜欢这种麻醉方式。
