The Concept of Crown Shortening: Combination of Vertical Edgeless Preparation Technique and Modified Coronally Advanced Tunnel

This case report describes an interdisciplinary approach to the aesthetic rehabilitation in a 45-year-old woman bothered by excessively long anterior teeth. Digital Smile Analysis (DSA) guided treatment planning, ensuring optimal proportions and soft tissue integration. Vertical Edgeless Preparation Technique (VEP) was used to establish the correct vertical position of the finishing line. Modified Coronally Advanced Tunnel (MCAT) combined with modified-Connective Tissue Grafts (Micro- and Split-CTG) was performed for root coverage and soft tissue augmentation. After uneventful healing, final ceramic restorations were seated. The integration of BOPT and MCAT optimized periodontal and prosthetic outcomes, achieving a natural, harmonious smile. This approach highlights the synergy between periodontal plastic surgery and prosthodontics in an aesthetically challenging case.
