Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Be over 18 years of age; presence of antagonist teeth, which showed differences substrates due to the difficulty of screening; mutually protected occlusion with correct curvatures of Spee and Wilson and absence of loss of vertical dimension of occlusion; and presence of adequate insertion bone.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A lower surface wear of the crowns made of monolithic zirconia and antagonist teeth is expected to be verified and evaluated by means of a comparative analysis of the .STL (STereoLithography /Standard Triangle Language) files obtained by means of intraoral scans and measured in 3D digital software (Autodesk® MeshMixer). Data were collected and evaluated at 0 (day of crown installation), 6, 12, 24 and 36 months. | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to find no changes in the color stability of the ceramic crowns of both materials, verified by the measurement method using a spectrophotometer (VITA EasyShade®), and by analyzing ?E*, ?l*, ?a*, ?b* in which it was analyzed at times 0 (baseline - time of installation), 6, 12, 24 and 36 months;Both ceramic crowns are expected to show adequate survival, analyzed by clinical and radiographic examinations at 0, 6, 12, 24, and 36 month controls. | — |
