Fully digital workflow involving 3D-printed gingivectomy guide and 3D-printed wax-up to restore and reshape a congenitally missing central incisor after orthodontic treatment

Objective: This case report describes a multidisciplinary approach using a digital wax-up to fabricate a gingivectomy and crown lengthening guides, to reshape a lateral incisor into a central incisor and improve overall esthetics. Clinical considerations: Comprehensive treatment planning is crucial when executing a multidisciplinary workflow, with digital tools proving to be invaluable aids. In the present case, a digitally designed wax-up was employed to generate a digital surgical guide for reshaping the gingival architecture of a lateral incisor into that of a central incisor, followed by composite restorations. Conclusion: The application of a digital wax-up for the design of a surgical guide and the fabrication of a silicone index led to a predictable and successful outcome in reshaping a lateral into a central incisor. Clinical significance: Post-orthodontic reshaping using direct composite is widely accepted by pa- tients due to its cost-effectiveness and minimally invasive nature. This approach highlights the efficacy of digital technol- ogy in achieving precise dental restorations, highlighting its growing importance in modern dental practice.
