A Biomimetic Adhesive Approach for Restoring a Cracked Tooth in a Single Visit: A Case Report

This report evaluates the morphology-driven preparation technique (MDPT) for biomimetic restoration of a cracked maxillary first molar, focusing on its tooth-preserving benefits and clinical outcomes.

A 36-year-old male presented with 2 months of masticatory pain and recent spontaneous pain in the upper right posterior region (Tooth 16). Examination revealed occlusal cracks, confirmed as cracked tooth syndrome radiographically. Treatment included microscopic root canal therapy (biomechanical preparation, irrigation, and hybrid obturation) followed by MDPT-based restoration. The minimally invasive approach preserved natural morphology using digital impressions (3Shape TRIOS 5) and placed a lithium disilicate veneer with dual-cure resin cement under optimized bonding protocols.

MDPT achieved a complete pain resolution and functional restoration while preserving maximum dentin structure. Minimal preparation and immediate dentin sealing enhanced stability and reduced microleakage risk, with excellent esthetic integration.

MDPT represents an effective biomimetic solution for cracked teeth, combining minimal invasiveness with optimal clinical outcomes. The technique demonstrates significant advantages in tooth structure preservation and restoration longevity. Comparative studies are needed to further validate its clinical benefits.
