目的探讨不同修复材料对前牙牙冠延长术后冠修复患者牙周的影响。方法选取2013年1月至2015年6月于河南省郏县人民医院行前牙牙冠延长术治疗的患者120例(患牙146颗)作为研究对象,按照术后冠修复材料不同将其分为对照组(54例,患牙68颗)和研究组(66例,患牙78颗)。对照组患者行金属烤瓷修复;研究组患者行氧化锆全瓷修复,比较两组患者的临床疗效、临时修复体佩戴时间、康复时间、炎症发生情况。结果研究组患者牙周正常率明显高于对照组,差异有统计学意义(P<0.05);研究组患者的临时修复体佩戴时间、康复时间均明显短于对照组,差异均有统计学意义(均P<0.05);研究组患者牙周炎症发生率明显低于对照组,差异有统计学意义(P<0.05)。结论氧化锆全瓷修复材料应用于前牙牙冠延长术后冠修复中有利于促进患者牙周组织健康,缩短康复时间,并且能够降低炎症发生风险,较金属烤瓷修复材料治疗更具临床价值。
Objective To investigate the effect of different restoration materials on the periodontal tissues of patients with crown restoration after crown anterior extension. Methods From January 2013 to June 2015, 120 patients (146 teeth) who underwent anterior tooth crown extension in Yixian People’s Hospital of Henan Province were selected as the study subjects, and were divided into Control group (54 cases, 68 teeth) and study group (66 cases, teeth 78). Patients in the control group underwent restoration of metal porcelain. Patients in the study group underwent zirconia all-ceramic restoration. Clinical efficacy, temporary wearing time, recovery time and inflammation of the two groups were compared. Results The normal periodontal rate in the study group was significantly higher than that in the control group (P <0.05). The wearing time and recovery time of the temporary prosthesis in the study group were significantly shorter than those in the control group (All P <0.05). The incidence of periodontal inflammation in the study group was significantly lower than that in the control group (P <0.05). Conclusion The application of zirconia all-ceramic restoration material in crown restoration after crown anterior extension is beneficial to promote periodontal tissue health, shorten recovery time and reduce the risk of inflammation, which is more valuable than the treatment of metal-ceramic restoration.
