Actual (reported)When missing tooth structure or teeth are replaced, minimal biologic risk should be involved to re-establish function and esthetics. The increased use of the adhesive technique and preservation of dental tissues have greatly impacted conservative tooth preparation design. The development use of zirconia technology and all-ceramic systems has opened the potential for fabrication inlays zirconia bridges with durability and good aesthetics. 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.

Actual (reported)Change in marginal fit
To examine if there is a gap between inlay margins and tooth cavity margins .It will be measured by a probe.
Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application
Change in Material Integrity
To examine macroscopically the presence of cracks or fractures in the veneering ceramic (retainers or pontics) or any fractures at the connectors.
Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application
Change in the Retention Status
The resistance of a prosthesis to displacement will be measured.
Immediately within five minutes following cementation (T1), 3 months (T2), 6 months (T3), 12 months (T4) following application

The first design is going to be fabricated with CAD/CAM Zirconia and the occlusal surface from E-max Press.
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 a glaze layer to improve 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 an E-max Press layer to improve adhesion.
A coating of a glaze layer will be used at the inner surface of the bridge to improve adhesion
A coating of E-max Press layer will be used at the inner surface of the bridge to improve adhesion
