Summary
This study introduces novel custom-made copings for natural tooth overdentures, demonstrating excellent marginal fit. These cost-effective copings offer rapid chair-side preparation and protect root canal treatments.
Area of Science:
- Dental prosthetics
- Materials science in dentistry
Background:
- Overdentures on natural teeth require precise coping fit for long-term success.
- Current coping fabrication methods can be time-consuming and costly.
Purpose of the Study:
- To present and evaluate a new type of custom-made copings for overdentures supported by natural teeth.
- To assess the marginal fit of these novel copings.
Main Methods:
- Custom-made copings were fabricated on 10 extracted natural teeth.
- Marginal fit was microscopically evaluated using a mechanical device.
- Software was utilized for precise gap measurement.
Main Results:
- The fabricated copings exhibited satisfactory marginal fit.
- Mean gap measurements were below clinically accepted limits (mean: 25.3 µm, range: 7.3–56.5 µm).
Conclusions:
- The new custom-made copings offer a rapid, chair-side preparation method.
- This technique protects root canal treatments by allowing same-session preparation and cementation.
- The copings present a cost-effective solution for overdenture fabrication.
