目的 :探讨二氧化锆修复体在口腔修复中的应用效果及其对咀嚼能力的影响。方法 :以2014年3月~2015年9月在我院接受口腔修复治疗的患者为观察对象,根据其修复所用材料分为合金修复体组和二氧化锆修复体组。观察两组患者治疗前后咀嚼能力和牙龈指数的差异,比较两组患者治疗前后生活质量和满意度的差异。结果 :治疗前两组患者咀嚼能力无明显差别,治疗后,两组患者的咀嚼能力均较治疗前增高,且二氧化锆复合体组增高更明显;两组患者治疗前出血指数和牙龈指数无明显差别,治疗后,两组患者上述指标均较治疗前降低,且二氧化锆复合体组降低更明显;治疗后,二氧化锆复合体组患者活力、情绪角色、精神健康和总体健康的得分明显高于合金修复体组,而两组患者的躯体功能、躯体角色和肢体疼痛等得分无明显差别;二氧化锆复合体组满意度明显高于合金复合体组,差异具有统计学意义。结论 :口腔修复中使用二氧化锆修复体具有较好的效果,可明显改善患者的咀嚼能力,提高其生活质量。
Objective: To investigate the effect of zirconium dioxide restoration on oral rehabilitation and its effect on mastication. Methods: The patients undergoing oral repair in our hospital from March 2014 to September 2015 were divided into two groups: alloy restoration group and zirconium dioxide restoration group. The difference of masticatory ability and gingival index between the two groups before and after treatment was observed. The differences of the quality of life and satisfaction before and after treatment between the two groups were compared. Results: There was no significant difference in chewing ability between the two groups before treatment. After treatment, the chewing ability of both groups was higher than that before treatment, and the increase of Zirconia complex was more obvious. Before treatment, hemorrhage index and gingival index After treatment, the above indexes in both groups were lower than those before treatment, and the reduction in the zirconium dioxide complex group was more obvious. After treatment, the scores of vitality, emotional status, mental health and general health of the patients in the zirconium dioxide complex group Which was significantly higher than that of the alloy restoration group. There was no significant difference between the two groups in the scores of somatic function, body function and limb pain. The satisfaction of the zirconium dioxide complex group was significantly higher than that of the alloy composite group, the difference was statistically significant. Conclusion: The zirconia restoration used in oral repair has a good effect, which can significantly improve patients’ ability to chew and improve their quality of life.
