Fig. 4: Fine tooth structure fabricated through the one-droplet 3D printing process.

From: Continuous 3D printing from one single droplet

Fig. 4

a Scheme of the generation of the tooth model for the one-droplet 3D printing process. b, c Schemes (b), UV pattern sequences (c) and corresponding optical images (d) of the one-droplet 3D printing process, in which a resin droplet is cured into a desired tooth structure. e Scheme of the three selected crown structures and corresponding opposing dentition. Pink, green and orange indicate the crowns of a molar, a canine and an incisor. f Optical image of the one-droplet 3D printing process for printing artificial crown structures. g Optical and micro-CT characterization of the printed crown structures, including the printed molar, canine, and incisor crowns structures. h Fixation of the printed crowns into the model with opposing dentition, with appropriate contact with adjacent teeth and marginal integrity.
