Comparison of the Effect of Indirect Method Geramage Polymerized Porcelain Veneer and Direct Method Photocurable Resin Restoration in Patients with Vital Pulp Anterior Teeth
Objective To explore the difference in the application effect of indirect method Geramage polymeric porcelain veneer restoration and direct method photocurable resin veneer restoration in the aesthetics of vital pulp anterior teeth.Methods A total of 100 patients(240 affected teeth)who were admitted to the author's hospital from June 2018 to June 2021 and were divided into study group and control group with 50 patients in each group by random number table method.The research team used the indirect method of Gramage polymerized porcelain veneer restoration,and the control group used direct photocuring resin veneer repair.The cosmetic effects of PI,GI,PD,IL-1β,TNF-α and prosthesis were compared between the two groups.Results After 3 months of repair,the PI,GI,and PD values of the study group were significantly lower than the control group,and the differences were statistically significant(P＜0.05).Before treatment,the levels of IL-1β and TNF-α in the gingival crevicular fluid of the study group and the control group were not statistically significant(P＞0.05).Three months after treatment,the levels of IL-1β and TNF-α in the gingival crevicular fluid of the study group were significantly lower than those in the control group,and the difference was statistically significant(P＜0.05).At 12 months after treatment,the edge of the prosthesis of the study group,the color matching degree of the restoration and the adjacent teeth,and the fit of the edge of the prosthesis reached the A-level compliance rate higher than that of the control group(P＜0.05).There was no significant difference in the integrity of the restoration,the sensitivity of the abutment and the compliance rate of the pulpal state between the study group and the control group(P＞0.05).Conclusion The indirect method of Gramage polymer porcelain veneer prosthesis is superior to the direct photo-curing resin veneer repair in the prosthetic anterior teeth cosmetic,and has less impact on the health of the periodontal tissue.
