3D Printing in Orthodontics: An Introduction

Abstract

Aim: To introduce 3D printing to individuals or practices providing orthodontic treatment. Introduction: 3D printing or additive manufacturing is the fabrication of objects from a 3D digital model. 3D printing can be achieved by the successive deposition of photo-sensitive resin material, cured solid with a light source such as a laser. This allows for customisable appliances and improved workflow in practice. 3D printing is a rapidly evolving technology, with many practices beginning to implement it into their digital workflows. Adoption and integration come with many challenges. Conclusion: Provided suitable materials and 3D printing protocols are followed, 3D-printing produces accurate and robust dental models without the errors associated with conventional dental impressions and plaster models. While this involves the transition from conventional methods of fabrication and outsourcing to a fully digital workflow, savings and improved efficiencies can result.
