Guided tooth preparation device fabricated with a complete digital workflow: A dental technique

Guided tooth preparations allow clinicians to provide fixed dental prostheses for dentate patients in an efficient manner. One approach uses a digital preparation device technique where the preparation of a tooth needing a crown is guided by a device. Compared with conventional techniques, this method allows for accurate abutment preparation more efficiently and with improved quality. By controlling tooth preparation, this method preserves natural tooth structure and provides adequate clearance for the restorative material. To illustrate this technique, an adhesive minimally invasive fixed complete-mouth rehabilitation was provided by using a 3D-printed digital preparation device.
