Effects of digital chair-side CAD/CAM Onlay on repair of tooth defects
Objective:To observe effects of digital chair-side computer-aided design/computer-aided manufacturing(CAD/CAM)Onlay on repair of tooth defects.Methods:A prospective study was conducted on 80 patients with tooth defects admitted to this hospital from April 2022 to February 2023.They were divided into control group and study group according to the random number table method,40 cases in each group.The control group was treated with conventional impression to make Onlay repair,while the study group was treated with digital chairside CAD/CAM to make Onlay repair.The success rate of repair,the levels of inflammatory factors in gingival crevicular fluid[nuclear factor κB receptor activating factor(RANK),macrophage inflammatory protein-1α(MIP-1α)],the pain degree[numerical rating scale(NRS)]score,the periodontal indexes[gingival index(GI),gingival crevicular bleeding index(SBI),tooth mobility(TM),plaque index(PLI)]levels,the masticatory efficiency,the bite force level,and the incidence of complications.Results:The success rate of repair in the study group was 93.02% (40/43),which was higher than 75.61% (31/41)in the control group,and the difference was statistically significant(P<0.05).The chewing efficiency and bite force were higher than those of the control group,The incidence of complications and gingival crevicular fluid RANK,MIP-1α,NRS,SBI,TM,GI,and PLI scores in the study group were lower than those of the control group,and the differences were statistically significant(P<0.05).Conclusions:For dental defects,digital chair side CAD/CAM can improve the success rate of restoration,improve chewing and periodontal function,alleviate pain and inflammatory stimulation,reduce the risk of complications,and achieve better results than conventional impression based high inlay restoration.
