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 ANDCONCLUSION:
(1) Occlusal force The occlusal force in all the five groups was increased immediately and 6 months after restoration (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.
