To explore the application effect of new material after surface modification of zirconia ceramics and patient evaluation.
A total of 60 patients with tooth defect treated in our hospital from April 2020 to April 2021 were selected as the study subjects and randomly divided into the control group and experimental group, with 30 cases each. The patients in the control group were treated with glass-ceramics, and those in the experimental group received LiSi surface treatment, so as to compare the application effect and patients' evaluation between the two groups.
Between the two groups, no obvious differences in surface loss, adhesive strength, and transmittance at 3 months, 6 months, and 1 year were not observed ( > 0.05); and after intervention, the score on dental aesthetics, hardness value, and occlusal force were obviously higher in the experimental group than in the control group ( < 0.001).
The new material enables forming an acid etchable coating on the zirconia surface, increases the adhesive strength, and achieves an aesthetic degree that is welcomed by the patients; meanwhile, after grinding, the edge is defect free and the tightness is higher. Further research will help to establish a better solution for patients.
探讨氧化锆陶瓷表面改性新材料的应用效果及患者评价。
选取 2020 年 4 月至 2021 年 4 月在我院就诊的 60 例牙体缺损患者作为研究对象，随机分为对照组和实验组，各 30 例。对照组患者采用玻璃陶瓷修复，实验组患者采用 LiSi 表面处理，比较两组的应用效果和患者评价。
两组患者在 3 个月、6 个月和 1 年时的表面损耗、黏附强度和透光率比较，差异均无统计学意义（>0.05）；干预后，实验组患者在牙齿美观、硬度值和咬合力度方面的评分明显高于对照组（<0.001）。
新材料可在氧化锆表面形成可酸蚀的涂层，提高黏附强度，达到患者所欢迎的美观程度；同时，研磨后边缘无缺陷，密合度更高。进一步的研究将有助于为患者建立更好的解决方案。
