The Effect of Using the CEREC Digital All-Porcelain Repair System to Produce All-Porcelain High Inlay for the Restoration of Severely Damaged Molars
Objective To explore the effect of using the CEREC digital all-porcelain repair system to produce all-porcelain high inlay for the restoration of severely damaged molars.Methods With the selection of sixty patients with severe damaged molars admitted to the hospital from March 2019 to September 2022 as the research subjects,after adjusting for confounding factors based on propensity matching method,patients were divided into the control group and the experimental group,with 30 cases in each group.With the control group treated with full crown restoration,while the experimental group was treated with all-porcelain high inlay restoration using the CEREC digital all-porcelain repair system,the effects of the two groups at 6 and 12 months after repair(including edge fit,prosthesis integrity,prosthesis loosening/detachment,gingival health,prosthesis staining),masticatory function(evaluated by chewing efficiency)and quality of life[evaluated by the oral health impact profile-14(OHIP-14)]before repair and 6 and 12 months after repair were compared between the two groups.In addition,the incidence of two groups of adverse events(food impaction,gum redness and swelling,loose teeth,and loss of prosthesis)was statistically analyzed.Results After 6 and 12 months of repair,the scores of various repair effects in the experimental group were higher than those in the control group,and the differences were statistically significant(P＜0.05);The scores of various repair effects after 12 months of repair in the two groups were lower than those after 6 months of repair,and the differences were statistically significant(P＜0.05).Before repair,there were no significant differences in chewing efficiency and OHIP-14 score between the two groups(P＞0.05);After 6 and 12 months of repair,the chewing efficiency of both groups was higher than before repair in the same group,and the OHIP-14 score was lower than before repair in the same group.In addition,the chewing efficiency of the experimental group was higher than that of the control group,and the OHIP-14 score was lower than that of the control group,with statistically significant differences(P＜0.05).The incidence of adverse events in the experimental group was lower than that in the control group,and the difference was statistically significant(P＜0.05).Conclusions The use of the the CEREC digital all-porcelain repair system to produce all-porcelain high inlay restorations for severely damaged molars was more effective than full crown restorations.It can effectively improve patients'chewing function and quality of life,and reduce the occurrence of adverse events.
