The Repair Effect of E-Max Cast Porcelain High Inlay and Lava Ultimate Super Tough Porcelain High Inlay Defects and Their Effects on Chewing Function and Gingival Condition
Objective:To investigate the effect of E-MAX and lava ultimate on masticatory function and gingival status.Methods:100 cases of patients with tooth defect in our hospital from August 2020 to August 2021 were selected as the research object and randomly divided into lava ultimate group and E-MAX group,with 50 cases in each group.The patients in both groups were treated with high inlay repair,the lava ultimate group was treated with lava ultimate high toughness porcelain for high inlay repair,and the E-MAX group was treated with E-MAX cast porcelain for high inlay repair.The repair success rate and satisfaction were compared.All patients were fol-lowed up for 2 years,and the masticatory function and aesthetic scores,plaque index(PLI),bleeding index(BI),probing depth of gingi-val sulcus(PD)before repair,12 months and 24 months after repair were recorded Clinical attachment loss(CAL)related periodontal health indicators and the expression levels of alkaline phosphatase in gingival crevicular fluid(ALP)and GCF in gingival crevicular fluid(GCF).Results:There was no significant difference in the success rate of repair and satisfaction between the two groups(P＞0.05);There was no significant difference in masticatory function and aesthetic score between the two groups before repair(P＞0.05).Masticatory func-tion and aesthetic score were increased in the two groups 12 months and 24 months after repair,but there was no significant difference in aesthetic score between the two groups(P＞0.05).Masticatory function in lava ultimate group was better than that in E-MAX group 24 months after repair(P＜0.05);There was no significant difference in the levels of CAL,PD,Bi and PLI between the two groups before re-pair(P＞0.05).The levels of CAL,PD,Bi and PLI in the two groups were decreased 12 months and 24 months after repair(P＜0.05),but there was no significant difference between lava ultimate group and E-MAX group(P＞0.05);There was no significant difference in ALP content and GCF level between the two groups before repair(P＞0.05).There was no significant change in ALP content and GCF level be-tween the two groups 12 months and 24 months after repair(P＜0.05).There was no significant difference between lava ultimate group and E-MAX group(P＞0.05).Conclusion:The repair effects of E-max cast porcelain high inlay and Lava Ultimate excellent toughness porcelain high inlay defects are both significant,and both can improve patient satisfaction with restoration,improve chewing function,and aesthetic scores.Improving periodontal health and gingival condition,but Lava Ultimate superior toughness porcelain high inlay restoration for dental defects has better chewing function in long-term patients than E-max cast porcelain high inlay restoration.
