This article demonstrates a case that successfully placed a retro-fitted crown restoration under an
existing denture by employing the characteristics of digital technology. Scanned data of the arch that
involves edentulous area, and ofthe old denture itselfwere obtained and superimposed on each other.
A virtual crown was modeled in computer-aided design software with marginally larger than the
ideal size. The old denture was regarded as an adjacent tooth in the setting menu so that the portion
ofthe virtual crown that extends over to the old denture could be automatically deleted by selecting
the “Cut intersections” option. This retro-fitted crown was milled with a polymethylmethacrylate disc
after a minor adjustment ofits contour. The crown and the old denture were placed in the patient’s
mouth, and resulted in favorable esthetic outcome and occlusion, showing proper relationship with
the old denture.
