Summary
Restoring fractured posterior teeth with partial coverage restorations preserves tooth structure. Air-abraded nonprecious metal bonded with adhesive resin offers a minimally invasive solution for enamel-dentin fractures.
Area of Science:
- Restorative Dentistry
- Dental Materials Science
Background:
- Enamel-dentin fractures in posterior teeth require restoration of form and function.
- Preserving sound tooth structure is a primary goal in treating these fractures.
Purpose of the Study:
- To propose a minimally invasive approach for restoring enamel-dentin fractures in posterior teeth.
- To evaluate the potential of a cast partial-coverage restoration using nonprecious metal and adhesive resin.
Main Methods:
- A partial-coverage restoration cast in nonprecious metal was designed.
- The metal restoration was air-abraded for enhanced bonding.
- The restoration was bonded to the tooth using an adhesive resin.
Main Results:
- The adhesive resin demonstrated a strong bond to both tooth structure (enamel and dentin) and the air-abraded metal.
- This bonding facilitated the simple fabrication of a cast partial-coverage restoration.
Conclusions:
- The suggested method allows for minimal tooth preparation.
- This technique effectively restores form and function while conserving tooth material.
