摘要
目的上颌前牙牙体缺损为临床常见牙体缺损部位,而如何高效地进行牙体修复为目前临床研究热点,本研究旨在探讨改良后的牙冠延长术对上颌前牙牙体缺损治疗效果及美观度的影响。方法选取我科自2019年12月-2021年3月治疗的80例行牙体修复的上颌前牙牙体缺损的患者作为研究对象,其中分为对照组(n=40)、研究组(n=40),对照组患者进行直接桩核冠修复,研究组患者先进行改良后的牙冠延长术,再完成桩核冠修复,治疗后随访3个月。比较两组患者治疗总有效率,以及治疗后6周、3个月牙周袋探诊深度(PD)、菌斑指数(PLI)、龈沟出血指数(SBI)及牙龈指数(GI)水平,Key牙齿美观(Class)分级。结果研究组患者治疗总有效率高于对照组,差异有统计学意义(P<0.05)。术后6周、3个月,两组患者PD、PLI、SBI、GI水平均低于术前,差异有统计学意义(P<0.05);且研究组患者PD、PLI、SBI、GI水平均低于对照组,差异有统计学意义(P<0.05)。术后3个月,研究组患者Class分级优于对照组,差异有统计学意义(P<0.05)。结论上颌前牙牙体缺损不仅影响口腔功能,还影响口腔美观,牙体修复为主要治疗方法,本研究发现在桩核冠修复之前,进行改良后的牙冠延长术治疗,术后不仅能提高临床疗效,改善患者牙周状况,还能更好地提高口腔美观度。
Objective Maxillary anterior tooth defect is a common part of clinical tooth defect,and how to effectively carry out tooth repair is a hot spot of clinical research.This study aims to explore the effect of improved crown lengthening on the treatment of maxillary anterior tooth defect and aesthetic.Methods From December 2019 to March 2021,80 patients with maxillary anterior teeth defect were selected as the research object,which were divided into control group(n=40)and study group(n=40).The control group was treated with direct post core crown restoration,and the study group was treated with improved crown lengthening,and then completed post core crown restoration.The patients in the study group were followed up for 3 months after treatment.The total effective rate,probing depth of periodontal pocket(PD),plaque index(PLI),sulcus bleeding index(SBI)and gingival index(GI)levels,and key teeth aesthetic(class)grading were compared between the two groups 6 weeks and 3 months after treatment.Results The total effective rate of the study group was higher than that of the control group,the difference was statistically significant(P<0.05).At 6 weeks and 3 months after operation,the levels of PD,PLI,SBI and GI in the two groups were lower than those before operation(P<0.05);The levels of PD,PLI,SBI and GI in the study group were lower than those in the control group(P<0.05).Three months after operation,the class of the study group was better than that of the control group,and the difference was statistically significant(P<0.05).Conclusion The defect of maxillary anterior teeth not only affects the oral function,but also affects the oral beauty.The main treatment method is dental restoration.This study found that before the post core crown restoration,the improved crown lengthening treatment can not only improve the clinical curative effect,improve the periodontal condition of patients,but also better improve the oral beauty.
