Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The purpose of this study is to clinically evaluate the placement of inlay bridge made of a Y-TZP framework veneered with a pressed ceramic and bonded with a completely adhesive approach in the replacement of a single missing tooth.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The second design is going to be fabricated with CAD/CAM Zirconia and the occlusal surface from e-max press and the internal surface coated with glaze layer to improve the adhesion.
The third design is going to be fabricated with CAD/CAM Zirconia and the occlusal surface from e-max press and the internal surface coated with a layer of e-max ceramic press to improve the adhesion.
