Multi-stage 3D-printed guide for precise restoration of severely inclined teeth based on target restorative space guidance: a case report

doi:10.7518/hxkq.2024.2023428

Abstract

Abstract:

In clinical dentistry, addressing unique conditions such as tilted, elongated, and torsion teeth during preparation can be effectively managed through digital tooth morphology design. The production of a multi-stage 3D-printed guide offered a more efficient and accurate solution. This article presented a case of significant inclination, elongation, and torsion in the maxillary and mandibular canines that were successfully treated using crown restoration modification. A crown preparation guide was fabricated based on the final form design of the restoration using the target restorative space analysis technique to ensure precise tooth preparation. A tooth preparation guide was also designed and utilized further to enhance accuracy and efficiency during complex tooth preparation. The combined application of these multi-stage guides demonstrated promising clinical prospects.

Key words: tooth preparation, digital design, 3D-printed guide, target restorative space
