How to Place a Composite Restoration

This novel tooth improves upon traditional dental training models by addressing several mechanical and pedagogical limitations associated with standard dentoform teeth. Key improvements include: • Non-Stick Surface: Unlike regular dentoform teeth, composite resin does not stick to this novel tooth, even when a bonding agent is used. This allows for the easy removal of the restoration for evaluation. • Realistic Light Transmission: The tooth is designed with light transmission properties similar to a natural tooth, which is essential for accurately teaching and practicing light-curing techniques. • Simplified Installation: The tooth consists of two halves that snap into a dentiform, eliminating the need for the screws required by traditional models. • Comprehensive Inspection: Because the tooth functions as a mold that can be opened, students can remove the restoration to inspect it for internal defects, such as voids or areas where the material was not properly cured. • Advanced Quality Testing: The technology enables a unique feedback loop where the removed restoration can be placed in acetone for 15 minutes. This process reveals curing deficiencies by turning partially cured material "frosty," providing a clear visual representation of the effectiveness of the student's technique or curing light. • Demonstration Versatility: The model is highly adaptable, allowing instructors to demonstrate the differences between incremental and bulk filling, as well as the impact of various curing lights, angles, and techniques. In essence, this technology acts like a "reveal" in a magic trick; while traditional models only show the final surface, this system allows the "magician" to pull back the curtain and inspect the structural integrity of the restoration from the inside out.
