非贵金属材料钴铬合金烤瓷联冠及烤瓷桥修复后基牙咬合力与牙周组织的变化
Occlusal force of the abutment teeth and periodontal changes after CO-Cr alloy-based porcelain-fused-to-metal crown and bridge restoration
摘要
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 aloy porcelain crown repair of the premolar (group B), CO-Cr aloy 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.关键词
