玻璃纤维桩联合全瓷冠修复前牙大面积缺损效果及对咀嚼能力的影响

Effect of glass fiber post combined with all-ceramic crown in repairing large-area defects of anterior teeth and its influence on chewing ability

目的探讨玻璃纤维桩联合全瓷冠修复前牙大面积缺损的效果及对咀嚼能力的影响。方法选取2018年8月至2020年8月中国人民解放军联勤保障部队第九〇四医院收治的前牙大面积缺损患者82例(112颗牙),依照随机数字表法分为对照组(41例,54颗牙)和研究组(41例,58颗牙)。对照组采用金属桩钴铬烤瓷冠修复,研究组采用玻璃纤维桩联合全瓷冠修复。两组均随访6个月,比较两组修复效果,修复成功率,咀嚼效率,龈沟液基质金属蛋白酶2(MMP2)、细胞间黏附分子1(ICAM1)、碱性磷酸酶(ALP)水平,记录随访期间并发症的发生情况。结果研究组修复完整度、颜色匹配、边缘适合性优于对照组,差异有统计学意义(P<0.05)。研究组修复成功率高于对照组,差异有统计学意义(P<0.05)。修复后6个月,两组咀嚼效率高于治疗前,且研究组高于对照组,差异有统计学意义(P<0.05)。修复后6个月,两组龈沟液MMP2、ICAM1、ALP高于修复前,且研究组低于对照组,差异有统计学意义(P<0.05)。两组并发症发生率比较,差异无统计学意义(P>0.05)。结论玻璃纤维桩联合全瓷冠修复前牙大面积缺损修复效果好,成功率高,同时对牙周组织刺激较小,是一种安全可靠的修复方法。

Objective To explore the effect of glass fiber post combined with all-ceramic crowns in repairing large-area defects of anterior teeth and its influence on chewing ability.Methods A total of 82(112 teeth)with large anterior teeth defects admitted to the 904th Hospital,Joint Logistic Support Force of the Chinese People’s Liberation Army from August 2018 to August 2020 were selected,they were divided into control group(41 cases,54 teeth)and study group(41 cases,58 teeth)according to the random number table method.The control group was repaired metal post cobalt-chromium porcelain crowns,while the study group was repaired glass fiber post combined with all-ceramic crowns.Patients in both groups were followed up for six months,the repair effect,repair success rate,chewing efficiency,and gingival crevicular fluid metalloproteinase 2(MMP2),intercellular adhesion molecule 1(ICAM1),alkaline phosphatase(ALP)levels were compared,the incidence of complications during follow-up was recorded.Results The repair integrity,color matching,and edge fitness of study group were better than those of control group,and the differences were statistically significant(P<0.05).The repair success rate of study group was higher than that of control group,and the difference was statistically significant(P<0.05).Six months after restoration,the chewing efficiency of two groups were higher than that before restoration,and study group was higher than control group,and the differences were statistically significant(P<0.05).Six months after restoration,the levels of gingival crevicular fluid MMP2,ICAM1,and ALP were higher than those before restoration,and study group was lower than control group,and the differences were statistically significant(P<0.05).There was no significant difference in the incidence of complications between two groups(P>0.05).Conclusion The glass fiber post combined with all-ceramic crown has a good effect in repairing large-area defects of anterior teeth,and high success rate,at the same time,the periodontal tissue stimulation is less,so it is a safe and reliable repair method.
