Clinical Study of CAD/CAM System Design of All-ceramic Onlay in the Repair of Dental Defects
摘要
Abstract
Objective To explore the clinical effect of computer aided design/Computer aided manufacturing(CAD/CAM)system design and fabrication of all-ceramic onlay on the repair of dental defects.Methods 91 patients(102 affected teeth)with dental defects who were treated in department of endodontics of stomatological hospital from June 2018 to June 2022 were selected as the study subjects,and they were repaired by CAD/CAM system fabrication of all-ceramic onlay.Modified United States Public Health Service(USPHS)was used to evaluate the repair effect immediately after repair,at 6 months after repair and at 12 months after repair.Periodontal indicators[gingival index,sulcus bleeding index,plaque index),gingival crevicular fluid aspartate transaminase(GCF-AST),gingival crevicular fluid alkaline phosphatase(GCF-ALP),interleukin-6(IL-6),interleukin-8(IL-8),tumor necrosis factor-α(TNF-α)]before and after repair,complications and satisfaction with shape,color and comfort of restoration at 12 months after repair were compared.Results The grade A ratio of USPHS evaluation was higher than 97.02%at 6 months after repair and 95.10%at 12 months after repair.Compared with before repair,the levels of AST,ALP,IL-6,IL-8 and TNF-α were all increased at 6 weeks after repair(P＜0.05),but there were no statistical differences in the above indicators at 6 months after repair(P＞0.05).The levels of SBI and PLI after repair were lower than those before repair(P＜0.05),and CAL after repair were higher than that before repair(P＜0.05).After 12 months of repair,the total incidence rate of complications was 3.92%.The patients'satisfaction with the shape,color and comfort of restoration were up to 93.41%or above.Conclusion CAD/CAM design and fabrication of all-ceramic onlay has a significant repair effect on dental defects,and it can return gingival creval fluid AST,ALP,IL-6,IL-8 and TNF-α to normal after 6 months,improve periodontal related indicators and maintain oral health.The incidence rates of complications are low and the symptoms disappear after intervention,and the patient satisfaction is high.关键词
