FIBER-REINFORCED COMPOSITES IN DENTAL IMPLANTS

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。放置在牙科植入物上的假体通常由金属子结构制成，该金属子结构支撑陶瓷贴面或树脂与人造塑料牙齿。在制造无金属植入假体中使用纤维复合材料技术可以解决与这种金属合金子结构相关的许多问题，例如腐蚀、毒性、制造复杂性、高成本和美学缺陷。 玻璃纤维增强复合材料（FRC）已经开发出来，它有可能利用简单、省时的技术制造美观的种植体假体下部结构。评价用于修复和替换牙齿的FRC修复体的实验室和临床研究表明，这些材料具有优异的机械性能，可以与树脂基贴面材料形成化学键。此外，这些FRC材料有可能用于在植入物加载之前进行单次访视、椅旁制造的临时牙齿替换，并与相邻的前牙粘合。

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.
