纯钛支架和Vitallium 2000铸造支架义齿在牙列缺损修复中的临床应用效果比较

Comparison of the Clinical Application Effect of Pure Titanium Frame and Vitallium 2000 Cast Frame Denture in the Repair of Dentition Defect

目的:比较纯钛支架义齿和Vitallium 2000铸造支架义齿修复牙列缺损的疗效及对患者义齿性口炎发生率的影响。方法:选择2017年1月-2019年11月笔者医院收治的牙列缺损患者116例,根据支架材料不同分为纯钛组和Vitallium组,每组58例。修复2年后,比较两组患者总体疗效、基托菌斑分布、基托菌斑指数情况、基托真菌培养结果、义齿性口炎发生情况及治疗满意度。结果:Vitallium组咀嚼效率、就位率高于纯钛组(P<0.05);修复2年后,两组基托组织面区域菌斑比率差异无统计学意义(P>0.05),而纯钛组基托菌斑指数高于Vitallium组(P<0.05);纯钛组白色念珠菌、热带念珠菌、褶皱念珠菌、光滑念珠菌菌落数量高于Vitallium组(P<0.05);纯钛组义齿性口炎总发生率、平均发生频率高于Vitallium组(P<0.05);纯钛组治疗总满意度低于Vitallium组(P<0.05)。结论:Vitallium 2000作为牙列缺损患者可拆除局部支架材料总体疗效高,较纯钛材料更能降低口腔细菌感染和义齿性口炎的发生,患者满意度更高。

Objective To compare the effects of pure titanium stent denture and Vitallium 2000 cast frame denture on the incidence of denture stomatitis in patients with dentition defects. Methods One hundred and sixteen patients with dentition defect admitted to the author's hospital from January 2017 to November 2019 were selected and divided into a pure titanium group and a Vitallium group according to different frame materials, 58 cases in each group. After 2 years of repair, the overall efficacy, base plaque distribution, base plaque index, base culture results, denture stomatitis conditions and treatment satisfaction were compared between the two groups. Results The masticatory efficiency and seating rate in the Vitallium group were higher than those in the pure titanium group(P<0.05). After 2 years of repair, there was no significant difference in the plaque ratio in the base tissue surface area between the two groups(P>0.05), while the base plaque index in the pure titanium group was higher than that in the Vitallium group(P<0.05). The number of colonies of Candida albicans, Streptococcus, Actinomyces and Lactobacillus in the pure titanium group was higher than that in the Vitallium group(P<0.05). The prevalence and severity of denture stomatitis were higher in the pure titanium group than in the Vitallium group(P<0.05). The total satisfaction with treatment in the pure titanium group was lower than that in the Vitallium group(P<0.05). Conclusion Vitallium 2000 as a removable local support material for patients with dentition defects can reduce the occurrence of oral bacterial infection and denture stomatitis with high satisfaction compared with pure titanium material.
