Inclusion criteria
Inclusion criteria: 1.Ages:18-60 years old; 2.Voluntarily participate in this study and sign the informed consent; 3.Volunteers without obvious aesthetic defects of the maxillary anterior teeth: no anterior tooth body defects, diastema, dental crowding, no dental arch defects, and facial defects; 4.Volunteers with aesthetic defects of the maxillary anterior teeth: with aesthetic defects of the maxillary anterior teeth (including anterior tooth body defects, poor tooth morphology, diastema, 1-6 anterior teeth missing), no missing lower anterior teeth and bilateral maxillary first premolars, with stable occlusion of the posterior teeth, and volunteers who can improve the aesthetics of the maxillary anterior teeth through restorative treatment; 5.Patients with aesthetic defects of the maxillary anterior teeth who need aesthetic restoration of the maxillary anterior teeth: with aesthetic defects of the maxillary anterior teeth (including anterior tooth body defects, poor tooth morphology, diastema, 1-6 anterior teeth missing), no missing lower anterior teeth and bilateral maxillary first premolars, with stable occlusion of the posterior teeth, and volunteers who can improve the aesthetics of the maxillary anterior teeth through restorative treatment.
Exclusion criteria
Exclusion criteria: 1.Moderate to severe dental crowding; 2.Missing of the lower anterior teeth or bilateral maxillary first premolars; 3.No stable occlusal relationship in the posterior teeth; 4.Patients with bone deformities requiring orthognathic surgery for aesthetic improvement; 5.Poor adherence to treatment procedures; 6.Other circumstances in which the investigator considers is inappropriate to participate in this study.
