目的:探讨硅橡胶软衬材料在下颌全口义齿修复中的应用价值。方法:选择2008年1月~2010年12月就诊的牙槽低平或呈刃状、骨倒凹大、黏膜薄等自身固有条件差的下颌全口义齿42例,采用硅橡胶软衬材料进行义齿重衬。随后,针对重衬后义齿的固位效果、咀嚼功能、舒适度、综合满意度等方面进行动态追踪调查,以分析该材料在下颌全口义齿修复中的应用价值。结果:采用硅橡胶软衬材料重衬后7 d与3、6、24个月后接受治疗的患者在上述各项指标的满意率均显著高于重衬前(P<0.05)。结论:对于牙槽或黏膜等固有条件差的患者,下颌全口义齿中硅橡胶软衬材料衬垫的使用能有效减少义齿固位差、咀嚼功能低、疼痛等不良结果,因而该材料在下颌全口义齿固有条件差的患者中具有较好的应用价值。
Objective: To investigate the value of silicone rubber lining material in the restoration of mandibular complete denture. Methods: From January 2008 to December 2010, 42 cases of mandibular complete dentures with low or flat alveolarity, large bone invagination, and thin mucous membrane were selected. Silicone rubber soft lining material Denture lining. Subsequently, the dynamic follow-up investigation was conducted on the retention effect, the masticatory function, the comfort degree and the comprehensive satisfaction of the re-dentition denture to analyze the application value of the material in the restoration of the mandibular complete denture. Results: The satisfaction rates of the above indexes in 7 days, 3 months, 6 months and 24 months after re-lining with silicone rubber lining material were significantly higher than before re-lining (P <0.05). CONCLUSION: The use of silicone rubber lining material in mandibular complete denture can effectively reduce the poor retention of denture, low masticatory function and pain in patients with poor inherent conditions such as alveolar or mucosa. Therefore, Complete denture patients with poor natural conditions have good value.
