Provisional restorations are vital to fixed prosthodontics treatment, providing an important diagnostic function while in place. In addition to protecting the prepared teeth, provisionalization enables clinicians to refine biologic and biomechanical issues before the final restoration is fabricated. Adjustments can be made in the provisional restoration to achieve both the clinician's and patient's desired results. The fabrication of temporary restorations requires that clinicians be proficient with a variety of materials and techniques that can be used to make well-adapted and functional provisionals. There are many material choices available to temporize a single crown as well as multi-unit fixed partial dentures, and the selection of provisional materials should be made based on a case-by-case evaluation. This article provides a review of polymeric resin provisional materials.
临时修复体对于固定义齿修复治疗至关重要，在其就位时具有重要的诊断功能。除了保护预备牙外，制作临时修复体还能使临床医生在制作最终修复体之前优化生物学和生物力学问题。可以在临时修复体上进行调整，以实现临床医生和患者期望的效果。制作临时修复体要求临床医生熟练掌握多种可用于制作贴合且功能良好的临时修复体的材料和技术。有许多材料可供选择来制作单冠以及多单位固定局部义齿的临时修复体，临时材料的选择应根据具体病例进行评估。本文对聚合树脂临时材料进行综述。
