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.
