Digital tooth reduction guides for esthetic rehabilitation of severely malformed and misaligned teeth: A clinical report.

This clinical report describes a digital workflow to fabricate digital tooth reduction guides for the esthetic rehabilitation of severely malformed and misaligned teeth by referencing the contours established during digital esthetic planning. For accurate trial restorations, primary reduction guides with reserved windows were fabricated to identify areas of tooth structure protruding beyond the planned contours. The secondary reduction guide enabled visualization of the intended restorative form and real-time assessment of tooth reduction. The combined use of both guides provided a predictable, efficient, and conservative approach for restoring severely malformed and misaligned teeth.
