The Effect of IPS e.max Press Porcelain Onlay and the High Onlay Made by the Planmeca CADCAM System in Repairing Posterior Dental Defects was Compared and Analyzed
Objective:The purpose of this study was to compare and analyze the effect of IPS e.max Press porcelain onlay and Planmeca CADCAM System in repairing posterior dental defects.Methods:A total of 60 patients(86 teeth)with posterior dental defects diagnosed and treated in our hospital from August 2021 to August 2022 were selected as the research objects.By using random number table method,they were divided into the study group(receiving onlay repair made by Planmeca CADCAM System)and the control group(receiving IPS E.axpress cast porcelain onlay repair),with 30 cases in each group.Chewing function,gingival condition,RANK,CXCL16 level,IL-6 and IL-8 level were compared between the two groups before and 1 year after restoration,and the results of restoration and satisfaction with cosmetic effect were statistically analyzed.Results:(1)Before repair,there was no difference in masticatory function between the two groups(P＞0.05);After 1 year of repair,the masticatory function of the study group was better than that of the control group(P＜0.05).(2)Before repair,there was no difference in gingival index and plaque index scores between the two groups(P＞0.05);After 1 year of repair,the gingival index and plaque index scores of the study group were better than those of the control group(P＜0.05).(3)Before repair,RANK and CXCL16 levels were not different between the two groups(P＞0.05);After 1 year of repair,the RANK and CXCL16 levels in the study group were lower than those in the control group(P＜0.05).(4)Before repair,there was no difference in IL-6 and IL-8 levels between the two groups(P＞0.05);After 1 year of repair,the levels of IL-6 and IL-8 in the study group were compared with those in the control group(P＞0.05).(5)After 1 year of restoration,the edge suitability and adjacent anatomical morphology of the restoration in the study group were better than those in the control group(P＜0.05).There were no significant differences in surface and edge coloring,fracture and retention between the two groups(P＞0.05).(6)One year after restoration,the satisfaction of the study group was better than that of the control group(P＜0.05).Conclusion:Compared with IPS e.max Press porcelain onlay,the onlay made by Planmeca CADCAM System can improve the chewing function,improve the gingival index,and improve the satisfaction of aesthetic teeth.
