FIBER-REINFORCED COMPOSITES IN DENTAL IMPLANTS

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。放置在牙种植体上的假体通常由金属基底结构制成，支撑陶瓷贴面或树脂和人造塑料牙齿。使用纤维复合材料技术制造无金属假体可以解决与这种金属合金子结构相关的许多问题，如腐蚀、毒性、制造复杂性、高成本和美观缺陷。玻璃纤维增强复合材料（FRCs）有潜力利用一种简单、省时的技术制造美观的植入假体亚结构。实验室和临床研究评估了用于修复和替换牙齿的FRC假体，表明这些材料具有优异的机械性能，并且可以与树脂基贴面材料形成化学键合。此外，这些FRC材料有潜力用于单次就诊，在种植体装载之前，椅子上制造的临时牙齿替代物与相邻的前牙结合。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Prostheses placed over dental implants are generally made with a metal substructure supporting either a ceramic veneer or resin with artificial plastic teeth. The use of fiber composite technology in the creation of a metal-free implant prosthesis may solve many of the problems associated with this metal alloy substructure such as corrosion, toxicity, complexity of fabrication, high cost and esthetic deficiencies. Glass fiber-reinforced composites (FRCs) have been developed which have the potential to make an esthetic implant prosthesis substructure utilizing a simple, time-efficient technique. Laboratory and clinical research evaluating FRC prostheses used to restore and replace teeth have shown that these materials exhibit excellent mechanical properties and can form a chemical bond to resin-based veneer materials. Additionally, these FRC materials have the potential to be used to make a single visit, chairside-fabricated provisional tooth replacement bonded to an adjacent anterior tooth prior to implant loading.
