Figure 1

The overall strategy of aesthetic restoration of anterior teeth"

Figure 2

Attention should be paid to the shooting angle when taking photos of anterior teeth for aesthetic analysis A, the shooting angle is not perpendicular to the tooth surface; B, the photo cannot reflect the actual width-to-length ratio of the crown and the incisal edge curvature; C, the shooting angle is perpendicular to the tooth surface; D, the photo can reflect the actual width-to-length ratio of the crown and the incisal edge curvature."

Figure 3

Important aesthetic parameters related to aesthetic restoration of anterior teeth A, exposure of upper central incisors at rest; B, the ideal smile arc has the maxillary incisal edge curvature parallel to the curvature of the lower lip; C, changing the distal-incisal angle of the central and lateral incisors can adjust the incisal edge curvature; D, the width-to-length ratio of the maxillary central incisors; E, the ratios of the mesiodistal widths of the maxillary central incisors, lateral incisors and canines in the front view; F, the position of the gingival margin of the upper anterior teeth."
