Fully Digital Workflow for Personalized Polyetheretherketone Pre-formed Crowns for Deciduous Teeth in Post-pulpotomy Restorations:A Case Report

doi:10.13701/j.cnki.kqyxyj.2026.01.013

Abstract

Abstract: Preformed metal crowns are commonly used for restoration following endodontic treatment in deciduous or mixed dentition. However, these crowns suffer from poor aesthetics, hypersensitivity, and inadequate fit to dental tissues. These issues have been addressed by integrating digital technology with polyetheretherketone (PEEK), a novel material. This case report details a fully digital workflow to produce personalized PEEK prefabricated crowns for deciduous teeth using intraoral scanning, dental CAD software, and a PEEK cutting machine. This approach offers a new method for restoring dental defects in pediatric patients.

Key words: CAD/CAM, deciduous crown, PEEK
