Purpose: The purpose of the present study was to evaluate the effects of dental stone molds and three dimensional (3D)-printed molds on the color difference, translucency, surface roughness, and hardness of maxillofacial silicones.
Methods: To prepare molds, a rectangular body 20 mm in diameter and 2 mm in thickness, was designed with computer-aided design software. Two different dental gypsum molds were prepared with the lost-wax technique.
Defects in the facial region can be treated by maxillofacial prostheses however, fabrication of the prosthesis is a time-consuming process. The short lifetime of silicone material due to inherent deterioration has stimulated a search for more practical methods. This case report involves a semi-digital workflow for replacement of an ear prosthesis.

Thus, this case report presents the treatment of a severely damaged premolar tooth with coronal pulpotomy and a 3D-printed endocrown restoration. A 13-year-old patient with pain due to profound caries in the left maxillary second premolar tooth was referred to the Department of Pediatric Dentistry at Gazi University in Ankara, Türkiye.
