目的:本研究的目的是提供一个病例报告,其中可注射复合树脂技术被用作唇腭裂和美学不适患者的牙齿重新解剖的修复替代方案。材料和方法:治疗计划包括使用可流动的复合树脂对上颌前磨牙和犬齿进行重新解剖。这种树脂通过透明基质注入并固化,这是诊断蜡像模型的副本。执行修复时还观察到一些参数,例如应用时间和边际适应。此外,使用传统树脂的增量技术替换了上侧切牙上的旧复合树脂修复体,这有助于评估两种修复技术的颜色稳定性和断裂/磨损劣化。结果:临床病例报告显示,可注射技术是一次恢复牙齿解剖(形状和轮廓)的简单快捷的方法,因为可注射树脂可以容易地施加在邻间区域,而不需要手动雕刻树脂。在这种情况下,没有临床,视觉,或者在边缘变色中发现了摄影差异,颜色稳定性,随访一年后,两种修复技术的断裂/磨损恶化。结论:在小的重新解剖的情况下,专业人员可能有另一种临床选择进行恢复性治疗。此外,在小的解剖变化的情况下,可注射技术似乎需要更少的操作员技能和椅子时间以及更好的边缘适应。
Objective: The objective of this study is to present a
case report in which the injectable composite resin technique was used as a restorative alternative for dental re-anatomization in a patient with cleft lip and palate and aesthetic complaints. Materials and Methods: The treatment plan included the re-anatomization of the maxillary premolars and canines using a flowable composite resin. This resin was injected and cured through a transparent matrix, which was a copy of the diagnostic wax-up model. Some parameters such as application time and marginal adaptation were also observed when performing the restorations. Additionally, old composite resin restorations on the upper lateral incisors were replaced using the incremental technique with conventional resins, which helped to assess color stability and fracture/wear deterioration for both restorative techniques. Results: The clinical
case report shows that the injectable technique was a simple and quick method for restoring the anatomy of teeth (shape and contour) in one session, since the injectable resin can be easily applied in interproximal areas without the need to manually sculpt the resin. In this
case, no clinical, visual, or photographic differences were found in marginal discoloration, color stability, and fracture/wear deterioration for the two restorative techniques after one year of follow-up. Conclusions: The professional may have another clinical option for restorative treatment in the
case of small re-anatomizations. In addition, the injectable technique seems to require less operator skill and chair time and better marginal adaptation in cases of small anatomical changes.
