钴铬合金、纯钛、Vitallium 2000及PEEK支架在可摘局部义齿中应用现状

Application Status of Cobalt-Chromium Alloy, Pure Titanium, Vitallium 2000, and PEEK Frameworks in Removable Partial Dentures

摘要: 背景：随着社会人口进入老龄化，牙齿缺损问题日益凸显。当前，牙列缺损的修复方式包括固定义齿、可摘义齿和种植辅助修复。尽管固定义齿和种植修复为首选，但考虑到经济、健康状况和舒适度等因素，可摘式义齿仍是合适的选择。方法：文章重点分析了钴铬合金、Vitallium 2000、纯钛和PEEK材料在可摘局部义齿中的应用现状，包括机械性能、生物相容性、临床效果和经济性。结果：钴铬合金因其高强度和良好的抗腐蚀性，适用于强咀嚼力患者，但其较重且美学效果差；纯钛材料具有极佳的生物相容性，适合金属过敏患者，然而强度较低，无法承受较大负荷；Vitallium 2000具备高强度和抗腐蚀性，适合高负荷患者，但成本较高；PEEK强度较低，但在美学效果和生物相容性上表现优异，适用于金属过敏患者和美学要求较高的患者。讨论：材料的选择应根据患者的需求、口腔健康状况以及修复体的功能要求做出综合考虑。展望：未来的研究将更加关注机械性能的改进、3D打印技术的应用以及智能化材料技术的进展，以实现更加个性化和智能化的义齿修复。

Abstract: Background: With the aging of the population, the issue of tooth loss has become increasingly prominent. Current methods for restoring dental defects include fixed dentures, removable dentures, and implant-supported restorations. Although fixed dentures and implant restorations are the preferred options, removable dentures remain a suitable choice considering factors such as cost, health condition, and comfort. Methods: This article focuses on the application status of cobalt-chromium alloy, Vitallium 2000, pure titanium, and PEEK materials in removable partial dentures, including their mechanical properties, biocompatibility, clinical effects, and cost-effectiveness. Results: Cobalt-chromium alloy, with its high strength and excellent corrosion resistance, is suitable for patients with strong chewing forces, but it is relatively heavy and has poor aesthetic effects. Pure titanium has excellent biocompatibility, making it ideal for patients with metal allergies, but its low strength makes it unable to bear large loads. Vitallium 2000 offers high strength and corrosion resistance, making it suitable for high-load patients, but it is costly. PEEK has lower strength but excels in aesthetic effects and biocompatibility, making it suitable for patients with metal allergies and those with higher aesthetic demands. Discussion: The choice of material should be based on a comprehensive consideration of the patient's needs, oral health condition, and the functional requirements of the restoration. Outlook: Future research will focus more on improving mechanical properties, applying 3D printing technology, and advancing smart material technologies to achieve more personalized and intelligent denture restorations.
