Abstract:
Objective:To explore the short-term clinical effects of digitally guided anterior teeth porcelain veneer restoration.Methods:17 patients with 80 teeth treated by digitally guided anterior teeth porcelain veneer restoration were included and divided into minimally invasive group(A,9 cases with 40 teeth)and the invasive group(B,8 cases with 40 teeth).The accuracy of tooth preparation guides was evaluated by Bland-Altman analysis,the clinical effects at 1 week and 3,6 and 12 months and the plaque in-dex at 12 months after operation were compared between the two groups.Results:The mean error of tooth preparation by the guide plate is(0.089±0.029)mm,and the mean differences in cervical and middle were smaller than that in incisal area.There were sta-tistically significant differences between the two groups in the follow-up clinical effect scores of color matching,gingival health and postoperative sensitivity(P＜0.05).The plaque index at 12 months after surgery was 0.67±0.41 in the minimally invasive group and 0.88±0.47 in the invasive group(P=0.026).Conclusion:The digitally guided porcelain veneer restoration realizes the visualiza-tion of tooth preparation and has good short-term clinical effects.
