Abstract

This article describes a technique for the fabrication of digital complete dentures guided by facial scanning using an innovative device for maxillomandibular relation records. For this, a device was designed and 3-dimensionally (3D) printed to assist in the maxillomandibular record stage. Digital files of the diagnostic casts, jaw relation record, and facial images were superimposed, and the complete denture was virtually planned. Subsequently, trial complete dentures were 3D printed, and a functional and esthetic clinical tooth evaluation was conducted. Then, definitive impressions were made, and definitive complete dentures were obtained. The method of recording the maxillomandibular relation associated with facial scanning in a digital workflow for manufacturing the dentures in a 3-appointment protocol provided better predictability of patient care and reduced clinical and laboratory time than with the conventional denture technique.
