Abstract

In the esthetic restoration of anterior teeth, trial restorations are an efficient way of communicating among patients, doctors, and dental laboratory technicians. Although the development of digital technologies has made it popular to design digital diagnostic waxing in a software program, problems such as the polymerization inhibition of silicone materials and time-consuming trimming remain. The silicone mold based on a 3-dimensionally printed resin cast still has to be transferred to the digital diagnostic waxing and to the patient's mouth to generate a trial restoration. A digital workflow is proposed to fabricate a double-layer guide to reproduce the digital diagnostic waxing in the patient's mouth. This technique is suitable for esthetic restorations of anterior teeth.
