Abstract: Objective To evaluate the clinical application value of minimal prepared ceramic veneer in anterior teeth,by analyzing the esthetic effects and success rates.Methods Forty-four anterior teeth in 30 patients with minor esthetic defect were included in this study.Less than 0.5 mm preparation or no preparaion technique was used in the clinical procedure.Glass ceramics veneers were delivered and 3M Relyx Veneer were used as the adhesive.The final appearance of each restoration was evaluated by patients on visual analogue scales ( VAS ) and by professional prosthodontists. Evaluation criteria included margin effects,color,shape and translucency.The success rate of all the restoration were analyzed in 6,12 and 24 month after the treatment. Results The patients' degree of satisfaction was 9.2 ±0.4,while the excellent rate of esthetic effect of margin effect,color,shape and translucency was 89% (39/44),91% (40/44),98 % ( 43/44 ) and 93 % ( 41/44 ) by professional prosthodontist.The success rate of 6,12 and 24 month were 100% (44/44),98% ( 43/44 ) and 91% (40/44).Conclusions The minimal prepared venneers have a good esthetic effect and a satisfactory success rate,and is a suitable technique in esthetic treatment under the critical indications.
