文题释义:
烤瓷牙修复:目前较为常用的方法有烤瓷联冠和烤瓷桥修复,其主要方式是在缺损或缺失牙的部位,用铸造贵金属或非贵金属作为支撑的内核,再在其外部用烤瓷来达到与真牙的颜色和功能相仿的效果。烤瓷牙修复具有美观、坚固耐磨、强度高、生物相容性好等特点,且患者修复后清洁更为方便;其不但能恢复患者的口腔功能,还能有效保护牙体硬组织和牙髓,减少外界刺激对牙髓的伤害。
咬合力:主要是指上下颌发生接触时咀嚼肌收缩产生的咀嚼压力,而牙周组织正常的组织结构和功能的维持均依赖于正常的咬合力作用,当咬合力发生改变后,牙周组织结构也会发生改变,以适应改变的功能状态。
 
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(P < 0.05);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(P < 0.05),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(P < 0.05);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(P > 0.05);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: To measure the occlusal force index of patients with missing teeth before and after restoration is an effective way to evaluate the restoration effect and oral function recovery after dental restoration.
OBJECTIVE: To observe the changes of occlusal force and periodontal tissue in patients undergoing CO-Cr alloy-based porcelain-fused-to-metal crown and bridge restoration.
METHODS: 100 male patients were randomly divided into five groups (n=20 per group), and respectively received CO-Cr alloy porcelain crown restoration of the anterior teeth (group A), CO-Cr alloy porcelain crown repair of the premolar (group B), CO-Cr alloy porcelain crown restoration of the molar (group C), CO-Cr alloy porcelain bridge restoration of the anterior teeth (group D), or CO-Cr alloy porcelain bridge restoration of the posterior teeth (group E). Changes of occlusal force and periodontal related indexes were detected before, immediately and 6 months after dental restoration.
RESULTS AND CONCLUSION: (1) Occlusal force: The occlusal force in all the five groups was increased immediately and 6 months after restoration (P < 0.05). Before, immediately and 6 months after dental restoration, the occlusal force was higher in the groups C and E than the groups A, B, D (P < 0.05), as well as higher in the group B than the groups A and D (P < 0.05). (2) Periodontal detection: there were no significant differences among the five groups in the periodontal probing depth, plaque control index, clinical attachment level, and volume of gingival crevicular fluid (P > 0.05) before and after restoration. To conclude, the CO-Cr alloy-based porcelain-fused-to-metal crown and bridge restoration can significantly enhance the patient’s occlusal force of the abutment teeth, exert little effect on the periodontal tissue and have good biocompatibility.
