Restoration of a Microdont Using the Resin Composite Injection Technique With a Fully Digital Workflow: A Flexible 3D-printed Index With a Stabilization Holder
2023
Abstract
Direct composite restorations are accepted as a treatment option for microdontia, which is a relatively prevalent condition that poses esthetic concerns. While free-hand composite placement is technique sensitive and time-consuming, the resin composite injection technique is more straightforward and predictable.
A fully digital workflow has been recently introduced, but the 3D-printed resin index is rigid to overcome undercuts, as opposed to the silicone index. This case report presents a flexible 3D-printed resin index, which can accurately transfer the digitally simulated functional and esthetic form to the final restoration.
In addition, a rigid holding clip was designed to stabilize the flexible index.
