Abstract:
Objective:To evaluate the clinical efficacy between preparation porcelain veneer(PPV)and no-preparation porcelain veneer(NPPV).Methods:44 patients with 97 PPVs and 23 patients with 57 NPPVs were followed up for 3 years.Mental tension, postoperative dentin sensitivity and satisfaction of the patients,survival rate of the veneers,sulcus bleeding index(SBI)of preopera-tive and postoperative 3 years were evaluated.A comparative analysis was taken to examine the clinical indicators of 2 groups accord-ing to the modified CDA /Ryge criteria.Results:Survival rates of PPVs and NPPVs were 96.91 % and 96.49%(P >0.05),satisfac-tion rates of the 2 group patients were 95.45% and 95.65%(P >0.05),respectively.Mental tension and the postoperative dentin sensitivity of patients in PPV group was higher than those in NPPV group.Preoperative and postoperative SBI were not statistically dif-ferent between the 2 groups(P >0.05).Marginal adaptation in PPV group was better than that in NPPV group.Color matching, Porcelain surface and Marginal stain were not statistically different between 2 groups.Conclusion:Preparation porcelain veneers and no-preparation porcelain veneers both are effective in clinical application.
