To demonstrate that it is possible to pursue teeth whitening treatment protocols during orthodontic treatment with no esthetic loss.
Many patients undergoing orthodontic treatment desire to have a straight and well aligned dentition, but also whiter teeth. For many years, it was believed that carrying out a whitening treatment with positioned orthodontic brackets in place would result in localized spots on the enamel labial surfaces of teeth. However, a deeper understanding of the bleaching process suggests that the oxidation caused by products, which results from hydrogen peroxide decomposition, are able to diffuse peripherally into the tooth structure and reach even that under the cemented brackets. Two in-office-bleaching treatments were performed in patients using orthodontic fixed braces in two or three 40-minute sessions using a 35% hydrogen peroxide.
In-office bleaching is possible and effective, even with orthodontic brackets in position. The teeth were successfully bleached despite the presence of brackets. All biological criteria have been fulfilled satisfying patients' expectations of aligned and whitened teeth in less time than if treatments had been performed separately, with satisfactory results and no esthetic loss.
The whitening of teeth is possible during orthodontic treatment with fixed braces without any esthetic loss. The in-office bleaching treatment with brackets in position also may act as a motivation factor, preventing patient withdrawal or treatment interruption. Therefore, at the end of the orthodontic treatment, the patient is able to display an aligned, functional and whitened smile. (J Esthet Restor Dent 29:83-92, 2017).
证明在正畸治疗中进行牙齿美白治疗方案而不影响美观是可行的。
许多接受正畸治疗的患者希望拥有整齐、排列良好的牙齿，但也希望牙齿更白。多年来，人们一直认为，在放置定位式正畸托槽的情况下进行美白治疗，会导致牙齿唇面釉质表面出现局部斑点。然而，对漂白过程的更深入了解表明，产品引起的氧化作用，源于过氧化氢的分解，能够向牙齿结构的周边扩散，并渗透到甚至粘在托槽下的部位。在使用固定正畸托槽的患者中，分两次或三次，每次 40 分钟，使用 35%过氧化氢进行了两次诊室美白治疗。
即使在有正畸托槽的情况下，诊室美白也是可能且有效的。尽管存在托槽，但牙齿仍成功地被漂白。所有的生物学标准都得到了满足，满足了患者对齐和美白牙齿的期望，治疗时间比分别进行治疗更短，结果令人满意，且没有美观损失。
在固定托槽正畸治疗中，牙齿美白是可行的，不会造成任何美观损失。有托槽的诊室漂白治疗也可能成为一个激励因素，防止患者退出或中断治疗。因此，在正畸治疗结束时，患者能够展现出整齐、功能正常和美白的笑容。
