This video describes and illustrates zirconia crown restoration in a patient with early childhood caries of the maxillary anterior teeth. Zirconia crowns for primary teeth confer many advantages, including great strength, durability, and ability to retain a high polish. The patient in this video received general anesthesia for full mouth dental rehabilitation, which guarantees optimal conditions for placement of technically demanding restorations. The video covers key aspects of the procedure, including bur selection, preparation, and subgingival reduction, and documents a novel approach to try-in and cementation that ensures predictable esthetic results. The principal components of this technique are trial alignment with fast-set impression material, pick-up impression of aligned crowns via transparent polyvinyl impression material, delivery of multiple units simultaneously, and command cure of resin-modified glass ionomer cement in the final restoration. Providers who watch this video will be well equipped to deliver anterior zirconia restorations for children with greater skill and confidence.

Introduction

This segment introduces zirconia crowns on a patient with early childhood caries affecting the maxillary anterior teeth.

Video Transcript

This video describes and illustrates zirconia crown restoration in a patient with early childhood caries affecting the maxillary anterior teeth. Radiographic and clinical examination revealed extensive decay affecting the four central incisors. A zirconia crown was chosen over direct composite restoration due to the size and extent of the lesions. Zirconia offers a restoration with great strength, durability, and the ability to retain a high polish. The patient in this video received general anesthesia for full mouth dental rehabilitation, guaranteeing optimal conditions for placement of technically demanding restorations.

The video covers key aspects of the procedure, including bur choice, tooth preparation, and crown selection. It also demonstrates a novel approach to try-in and cementation that ensures predictable esthetic results.
