Abstract

A 443-y male in good general health with a failing maxillary first molar due to a fractured mesio buccal root was treated with the resection of the root. After placing the interim restoration, tissues were allowed to heal for 6 months. Impressions were made with an intraoral scanner and the double cord retraction technique. The crown was fabricated with an entirely digital workflow, without the use of models. This procedure allows the optimization of the prosthodontic treatment phases, thereby reducing time and costs.
