Clinical Performance of 3D Printed Provisional Dental Crowns

Abstract

Novel 3-D printed provisional dental crowns show promising characteristics in laboratory studies that are similar to or better than traditional provisional crowns. As of this time there are no clinical studies comparing printed crowns to traditional directly fabricated crowns. Objective: The purpose of this study is to evaluate the short-term clinical performance of a 3D-printed provisional crown (Temporary CB, Formlabs) compared to a traditional direct provisional crown (Integrity, Dentsply Sirona). Methods: Each patient received a Temporary CB and an Integrity provisional crown on separate teeth opposing minimally restored natural teeth. Qualitative analysis was completed using the FDI World Dental Federation criteria for evaluation of restorative materials at the time of placement and at least three months after wearing the provisional crowns. Quantitative wear analysis was completed by superimposing digitally scanned baseline and 3-month images and quantifying the wear using spatial analysis software (Geomagic Freeform,3D Systems, Rock Hill, SC).
