Introduction
The use of 3D-printing in dentistry has experienced rapid growth in recent years and along with the development of new materials it can be used for permanent applications. 3D-printed resins are widely used in dental procedures due to their numerous benefits such as excellent mechanical properties and aesthetics. The aim of this presentation is to show the use of 3D printed resin as the material of choice through a case of an esthetic smile transformation using veneers.
Case Description
A 43-year-old man presented requesting to improve the esthetics of his smile with the shape of his teeth being his main complaint. Following extensive clinical and radiographic evaluation the digital simulations of the optional treatment plans were designed. The patient rejected any option that included orthodontic treatment leading to the final treatment plan being four 3D printed composite veneers at the central and lateral incisors. The core of the veneers was made by 3D printed resin (light-curing, free-flowing plastic based on methacrylic acid) and was layered to optimize the esthetic result with light-curing composite (which consist of 50% opalescent ceramic particles). The tooth preparations were done through the mockup two weeks after the teeth whitening and digital impressions were taken. One week later the cementation of the final restorations was done using universal adhesive and light-curing resin-based cement.
Discussion
Achieving the full potential of 3D printing relies on improvements in both dental materials and processes. Some printed resin materials have reached successfully mechanical properties comparable to milled and hybrid ceramics. Moreover, research indicates that the bonding to 3D printed restorations demonstrates excellent initial bond strength. Therefore, 3D Printed resins can provide an excellent alternative for numerous cases as they can be used for not only temporary but permanent restorations as well.
