Review on Preformed Crowns in Pediatric Dentistry-The Composition and Application

Klaudia Sztyler et al. Materials (Basel). .

Abstract

The purpose of this review is to compare and contrast the various types of preformed crowns that can be used to restore the primary teeth in children. Historically, preformed crowns have been widely available for the past 50 years. The clinical performance of preformed crowns has evolved to meet higher functional, mechanical, and aesthetic demands. Preformed crowns are available in a range of prefabricated sizes and shapes. Preformed crowns can vary depending on their properties, compounds, methods of preparation, and biocompatibility.

Keywords: material composition; pediatric crowns; primary teeth; repair procedures; teeth restoration.
