Abstract
BACKGROUND:In recent years, commonly used removable partial denture materials include Vitalium200 material, cobalt-chromium aloys and titanium materials. OBJECTIVE:To explore the value of different removable partial dentures in the repair of dentition defects. METHODS: Ninety cases of dentition defects, including 45 males and 45 females, aged 20-57 years old, were subject to removable partial denture repair. Among them, 30 cases were treated with Vitalium2000 removable partial dentures, 30 cases with titanium removable partial dentures, and 30 cases with cobalt-chromium removable partial denture. Denture inplace rate, incidence rates of denture stomatitis, periodontal disease and secondary caries, patient satisfaction self-evaluation were compared between three groups within 2 years after implantation. RESULTS AND CONCLUSION:Vitalium2000 material group was superior to pure titanium and cobalt-chromium aloy groups in the denture inplace rate, incidence rates of denture stomatitis, periodontal disease and secondary caries (P < 0.05). Patients in the Vitalium2000 material group were more satisfied with lightweight and comfort, aesthetics, chewing ability, odor degree of removable partial dentures than those in the other two groups (P < 0.05). These findings suggest that Vitalium2000 removable partial dentures can better improve the denture in place rate, reduce the incidence of denture stomatitis, periodontal disease and secondary caries, ensuring the comfort level and aesthetics of dentures.关键词
