Abstract
Objective To explore the whole porcelain restoration technology in orthodontic adult mild anterior tooth occlusal wrong application of deformities and the clinical curative effect of aesthetics. Method Selected our hospital from January 2011 to December 2011, because of the dislocation front teeth crowding, bad bite or tooth discoloration of mild wrong malformation of 62 cases of patients(80 anterior teeth) as the research object, according to the repair method divided into experimental group and control group. Experimental group were treated by repairing the all-ceramic restoration, control group were treated by nickelchromium alloy PFM crown restoration. Compared two groups of 6 months after treatment in patients with visual analogue scale(VAS) satisfaction score, before and 6, 12 months after treatment gingival index and 6 months after treatment restoration the revised standard rating of the American Public Health Association(USPHS score). Result After treatment in experimental group patients with the cut end of the trial defect, tooth surface defect and deformity of small teeth, tooth clearance, tooth staining and total satisfaction VAS scores were significantly higher than that of control group(P 0.05). 6 months after treatment in both groups of GI were significantly higher than before treatment, 12 months treatment after of GI were significantly less than 6 months after treatment(P 0.05); experimeutal group 6 months and 12 months after treatment ofGI were significantly lower than control group(P 0.01). Experimental group after treatment for 6 months ago dental restoration edge coloring and fit score was significantly higher than control group(P 0.05). Conclusion The whole porcelain restoration technique before orthodontic adult mild tooth occlusal wrong deformity curative effect is distinct, better than that of nickel-chromium alloy PFM crowns, suitable for mild crowded displacement before, bad bite or tooth discoloration of mild deformity, worthy of clinical application.
