整体切削的聚醚醚酮可摘局部义齿即刻修复1例

聚醚醚酮(PEEK)是一种具有良好的力学性能和生物安全性的新型高分子化合物,近年来逐渐应用于口腔修复、种植、正畸等领域。目前,PEEK在可摘局部义齿中的应用已有临床报道,但整体切削的PEEK可摘局部义齿还未见相关临床报道。本病例应用全程数字化设计和PEEK材料,整体切削制作了集支架、人工牙和基托为一体的可摘局部义齿,对1例83岁上下颌牙列缺损的患者进行了即刻修复治疗,并进行了3~6个月的随访,患者对修复效果满意。

Computer aided design and computer aided manufacturing-constructed polyetheretherketone removable partial dentures:a clinical report

Polyetheretherketone(PEEK)is a novel polymer compound with desirable mechanical properties and biosafety.It has been gradually used in the fields of prosthodontics,implantation,and orthodontics in recent years.Although the clinical application of PEEK in the frameworks of removable partial dentures has been reported,no related clinical studies on removable partial dentures fabricated with PEEK have been reported.In this case,a digital workflow was used to fabricate removable partial dentures with frameworks,artificial teeth,and bases using PEEK as the denture material.Immediate restoration was conducted on an 83-year-old patient with maxillary and mandibular dentition defects.Satisfactory results were observed at 3-6 months follow-up after treatments.
