Summary
This study introduces First Fit, a digital system for precise tooth preparation in ceramic veneer placement. It offers a minimally invasive approach, potentially allowing same-day cementation and reducing the need for temporaries.
Area of Science:
- Dentistry
- Digital Dentistry
- Restorative Dentistry
Background:
- Precise tooth structure reduction for ceramic veneers is a clinical challenge.
- Existing methods may lack accuracy and measurability in tooth preparation.
Purpose of the Study:
- To introduce First Fit, a novel digital technology for guided tooth preparation.
- To evaluate its advantages and limitations in ceramic veneer preparation.
Main Methods:
- The First Fit system utilizes 3D-printed guides and a specialized handpiece.
- It supports both one-step (same-day cementation) and two-step preparation approaches.
- Combines guided preparation with free-hand techniques when necessary.
Main Results:
- The system provides controlled and guided veneer preparation.
- Minimally invasive preparation is achieved.
- Enables same-day cementation in some cases, eliminating provisional restorations.
Conclusions:
- First Fit offers a precise, measurable, and minimally invasive method for veneer preparation.
- Digital CAD-CAM technology enhances predictability and efficiency in restorative dentistry.
