Accuracy in reproduction of bounded edentulous saddle areas using different cast fabrication methods: A comparison

Abstract

A common patient-request when presenting to restorative clinicians is replacement of missing teeth either by means of a fixed partial denture (FPD) or a removable partial denture (RPD). For decades, dental casts have been fabricated via the conventional cast fabrication technique which presents with its own set of disadvantages. To address these disadvantages, digital cast fabrication has been presented as an alternative. This is done via intraoral scanning and subsequent three-dimensional (3D) printing of dental models. However, the stitching process in intraoral scanning can be inadequate for areas lacking adequate geometry, such as edentulous saddle areas.
