文题释义:

可摘局部义齿:是一种患者可以自行摘戴的用于部分牙缺失(牙列缺损)的修复体。义齿主要通过固定在余留天然牙上的卡环等固位装置和基托保持义齿在牙列中的位置,利用天然牙和缺牙区剩余牙槽嵴做支持,恢复缺失牙及其周围缺损组织的解剖形态和生理功能。
纯钛材料、钴铬合金材料及Vitallum 2000材料的特点:纯钛合金在铸造过程中易产生气孔且制作工艺复杂,使用易着色,出现金属色泽变暗、菌斑附着等;钴铬合金铸造的支架在整体设计上因材料性能局限,存在体积大、基托设计变化小、卡环回弹性差等缺陷;Vitallum 2000材料是一种应用于铸造可摘局部义齿支架的新型合金,在730-1 100 范围高温内仍能保持良好的机械强度、抗热腐蚀性及抗氧化能力,其铸造的可摘局部义齿支架具有变形小、卡环易调节等优点。

 

背景:支架式可摘局部义齿是修补牙列缺损的主要方式,其铸造材料主要有纯钛材料、钴铬合金材料及Vitallum 2000材料。
目的:分析不同材料支架式可摘局部义齿修复牙列缺损的生物相容性。
方法:纳入120例牙列缺损患者,年龄24-68岁,均采用支架式可摘局部义齿进行修复,其中40例采用钴铬合金材料铸造支架式可摘局部义齿,40例采用纯钛材料铸造支架式可摘局部义齿,40例采用Vitallum 2000材料铸造支架式可摘局部义齿。随访2年,对比3组咀嚼效率、凝血情况、血栓、牙槽骨吸收、患者满意度,以及基牙牙周病及继发龋等不良反应发生率。

结果与结论:①咀嚼效率与患者满意率:Vitallum 2000材料组>纯钛材料组>钴铬合金材料组(P均< 0.05)。②凝血、血栓、牙槽骨吸收发生率:Vitallum 2000材料组<纯钛材料组<钴铬合金材料组(P均< 0.05)。③不良反应发生率:Vitallum 2000材料组<纯钛材料组<钴铬合金材料组(P均< 0.05)。④表明Vitallium 2000可摘局部义齿修复牙列缺损,可有效降低义齿性口炎、基牙牙周病及继发龋的发生率,保证舒适度、咀嚼力及语言功能。

Abstract:

BACKGROUND: Removable partial denture is the main way of repairing dentition defects, and its casting materials mainly include pure titanium, cobalt-chromium alloy and Vitallum 2000.
OBJECTIVE: To analyze the biocompatibility of removable partial dentures made of different materials in repair of dentition defects.
METHODS: Totally 120 patients with dentition defects, aged 24-68 years old, were enrolled and underwent repair with removable partial dentures. Among these patients, 40 patients were treated with cobalt-chromium alloy-casted removable partial dentures, 40 patients with pure titanium-casted removable partial dentures, and 40 patients with Vitallium 2000 casted removable partial dentures. All patients were followed up for 2 years. The chewing efficiency, coagulation, thrombosis, alveolar bone loss, patient satisfaction, and the incidence of adverse reactions, such as abutments periodontal disease and secondary caries were compared between these three groups.
RESULTS AND CONCLUSION: (1) Chewing efficiency and patient satisfaction rate: Vitallum 2000 group > titanium group > cobalt-chromium alloy group (P < 0.05). (2) Coagulation, thrombosis, the incidence of alveolar bone loss: Vitallum 2000 group < titanium material group < cobalt-chromium alloy group (all P < 0.05). (3) Incidence of adverse reactions: Vitallum 2000 group < titanium group < cobalt-chromium alloy group (P < 0.05). These results demonstrate that Vitallium 2000-casted removable partial denture in repair of dentition defects can effectively reduce the incidence of denture stomatitis, abutments periodontal disease and secondary caries, and ensure the comfort of the denture, chewing force and language function.
