Digital Workflow for Interdisciplinary Communication in Crown Lengthening Surgery

Abstract

When planning a prosthetic rehabilitation in the maxillary anterior, crown lengthening surgery is frequently indicated to adjust the position of the gingival margin and expose sufficient tooth structure for an ideal restoration. A surgical template can be used to prescribe the ideal postsurgical gingival architecture. However, producing a template that both seats onto the existing dentition and relates the desired gingival margin position is a clinical challenge. The digital workflow presented in this report employs a hybrid model merging the pre-prosthetic coronal tooth structure with the proposed postsurgical gingival margins. Using this model, the 3D printed surgical guide facilitates precise crown lengthening of the maxillary dentition.
