【摘要】：背景:测量牙缺失患者修复后的咬合力指标,可有效判断修复效果和患者修复后口腔功能的恢复情况。目的:观察行钴铬合金烤瓷联冠、烤瓷桥修复后患者基牙咬合力及牙周组织的变化。方法:将100例男性烤瓷牙修复患者随机分5组修复,其中20例采用钴铬合金烤瓷联冠修复前牙,20例采用钴铬合金烤瓷联冠修复前磨牙,20例采用钴铬合金烤瓷联冠修复磨牙,20例采用钴铬合金烤瓷桥修复前牙,20例采用钴铬合金烤瓷桥修复后牙。修复前、修复后即刻、修复后6个月,检测基牙咬合力变化及牙周相关指标变化。结果与结论:(1)咬合力:5组修复后即刻、修复后6个月的咬合力均高于修复前(P0.05);修复前、修复后即刻、修复后6个月,烤瓷联冠磨牙组、烤瓷桥后牙组的咬合力高于烤瓷联冠前磨牙组、烤瓷联冠前牙组、烤瓷桥前牙组(P0.05),烤瓷联冠前磨牙组咬合力高于烤瓷联冠前牙组、烤瓷桥前牙组(P0.05);(2)牙周组织:5组组内修复前后的牙周袋探诊深度、菌斑控制指数、临床附着水平、牙龈沟液量比较差异均无显著性意义(P0.05);5组间各指标比较差异均无显著性意义;(3)结果表明:行钴铬合金烤瓷联冠、烤瓷桥修复治疗能显著提升患者基牙咬合力,并且对牙周影响很小,生物相容性较好。
[Abstract]:Background: the index of the bite force after dental defect repair can be used to determine the effect of repair and the recovery of the oral function after repair. Objective: To observe the changes of CO Cr alloy porcelain fused to crown, the bite force of the base teeth and the changes of periodontium in the patients after the porcelain bridge repair. Methods: 100 cases of male porcelain prosthesis were randomly divided into 5 groups. Among them, 20 cases were repaired with cobalt chromium alloy porcelain fused to crown and 20 cases of cobalt chromium alloy porcelain fused to crown to repair premolar, 20 cases of cobalt chromium alloy porcelain fused to crown to repair molars, 20 cases of cobalt chromium alloy porcelain bridge to repair the anterior teeth and 20 cases of cobalt chromium alloy porcelain bridge to repair the posterior teeth. Results and conclusions: (1) bite force: the bite force of 5 groups was higher than that before repair (P0.05). Before repair, immediately after repair, 6 months after repair, porcelain fused crown molar group and porcelain bridge posterior teeth group were higher than that of porcelain fused to crown premolar group, porcelain fused to front teeth group, roast The premolar group of porcelain bridge (P0.05), the bite force of the PFM pre molar group was higher than that of the PFM anterior teeth group, the front tooth group (P0.05) of the porcelain bridge (2) the periodontal tissue in the 5 groups had no significant difference between the periodontal pocket detection depth, the plaque control index, the clinical attachment level, the gingival gingival volume ratio and the poor difference (P0.05), and the differences of the 5 groups were all different No significant significance; (3) the results showed that the combination of cobalt chromium alloy porcelain fused to porcelain crown and porcelain bridge repair can significantly improve the bite force of the base teeth, and have little influence on the periodontium and the biocompatibility is better.
