Designing a digital full arch in zirconia over a titanium t-base or titanium custom abutments using exocad software involves a thorough and precise process. Here's a detailed description of the digital design phase:

Digital Design:

1. Patient Assessment:

   • Start with a comprehensive assessment of the patient's oral health, including digital scans or impressions to create a virtual model.

2. Data Import into exocad:

   • Import the digital scans or impressions into exocad software to generate an accurate and detailed virtual representation of the patient's dental anatomy.

3. Titanium T-Base or Custom Abutment Integration:

   • Integrate virtual titanium t-base or custom abutments into the design, ensuring proper support for the zirconia full arch.
   • Verify the alignment and fit of the titanium components within the digital model.

4. Anatomical Design of Zirconia Arch:

   • Design the anatomical shape of the zirconia full arch, taking into account the patient's natural tooth anatomy and aesthetic preferences.
   • Ensure proper contouring and alignment with the underlying titanium t-base or custom abutments.

5. Functional Considerations:

   • Optimize occlusion and functional aspects, considering both natural teeth and implant-supported regions.
   • Verify proper articulation during various jaw movements.

6. Aesthetic Customization:

   • Customize the aesthetics of the zirconia restoration, including shade, texture, and translucency.
   • Achieve a natural appearance that blends seamlessly with the patient's remaining dentition.

7. Margins and Fit:

   • Define precise margins for both the zirconia and titanium components to ensure a snug fit.
   • Confirm the fit within the patient's oral anatomy, addressing any issues related to gaps or misalignment.

8. CAD Tools and Features:

   • Utilize exocad's CAD tools for detailed design modifications and adjustments.
   • Implement features specific to implant-supported restorations and titanium components.

9. Quality Control:

   • Conduct a thorough review of the digital design, checking for accuracy, fit, and overall satisfaction with the aesthetics.
   • Collaborate with dental professionals for feedback and adjustments if necessary.
