Correlation between clinical parameters of crown and gingival morphology of anterior teeth and periodontal biotypes.

Background: In this study, we conducted a quantitative analysis of the clinical parameters of crown and gingival morphology (CGM) of the maxillary anterior teeth (MAT). We also analyzed the correlation of these parameters with periodontal biotype (PB), with a view to providing objective standards for PB diagnosis.

Methods: The three-dimensional (3D) maxillary digital models of 56 individuals were obtained using an intra-oral scanner.
