Aesthetic Effect of All-ceramic Crown and Onlay in the Repair of Maxillary Premolar Defects and Its Influence on Periodontal Status
Objective To study the aesthetic effect of all-ceramic crown and onlay in the repair of maxillary premolar defects and its influence on periodontal status.Methods 85 patients with maxillary premolar defects admitted to the hospital from January 2019 to January 2022 were selected as the study subjects,and were divided into control group(n=42)and observation group(n=43)by the randomization method.The control group received all-ceramic crown repair,and the observation group was given onlay repair.The aesthetic effect,periodontal status,masticatory function and occurrence of complications were compared between the two groups of patients.Results ①In terms of shape contour and dental crown color,the scores of aesthetic effect aspects in observation group were higher than those in control group at 6 months and 12 months after repair(P＜0.05).Compared with before repair,the scores of mucosal texture and gingival papilla were increased at 6 months after repair,and the scores in observation group were slightly higher than those in control group during the same period(P＜0.05).The scores of mucosal texture and gingival papilla were enhanced at 12 months after repair compared with those at 6 months after repair,and the scores in observation group were significantly higher than those in control group(P＜0.05).②The probing depth(PD)and gingival index(GI)were decreased at 6 months after repair compared to before repair(P＜0.05),and the two indicators in observation group were slightly lower compared with those in control group during the same period(P＜0.05).The PD and GI at 12 months after repair were reduced compared with those at 6 months after repair(P＜0.05),and the PD and GI were significantly lower in observation group than those in control group(P＜0.05).③Compared with before repair,the scores of masticatory efficiency and occlusal force were risen at 6 months after repair,and the scores in observation group were higher than those in control group(P＜0.05).The scores of masticatory efficiency and occlusal force at 12 months after repair were decreased compared to 6 months after repair,and the scores in observation group were significantly higher compared to control group(P＜0.05).④At 6 months after repair,the scores of secondary caries and occlusal pain in observation group were slightly lower compared with those in control group(P＜0.05).Compared with 6 months after repair,the scores of secondary caries and occlusal pain in observation group at 12 months after repair were significantly lower than those in control group(P＜0.05).Conclusion Compared with all-ceramic crown repair,onlay repair has better aesthetic effect on patients with maxillary premolar defects,and it is more beneficial to periodontal health and has better masticatory function and lower incidence rate of complications.
