E06.420

Eligibility

Age

18 Years to 100 Years

Inclusion criteria

Inclusion criteria: Patients must be at least 18 years of age; good general health; at least 20 teeth present in the mouth; healthy gum tissue and use of two zirconia crowns in the anterior or posterior region; Where the maximum horizontal mobility is 1mm be accepted.

Exclusion criteria

Exclusion criteria: Patients who suffer from bruxism, poor oral hygiene and periodontal disease will be deleted.

Design outcomes

Primary

Measure	Time frame
Evaluate all crowns by two independent observers, calibrated, and after cementation over 1 week 6 months, 12 months and 24 months. Verified by the criteria of the modified USPHS (United States Public Health Service).	—

Secondary

Measure	Time frame
Evaluate differences between the two types of cementing agents, noting if the crowns are retained.;Evaluate differences between the two types of cementing agents, noting if the crowns have color stability.;Evaluate differences between the two types of cementing agents, noting if the crowns have marginal discoloration.;Evaluate differences between the two types of cementing agents, noting if the crowns have apresentam adaptação marginal.;Evaluate differences between the two types of cementing agents, noting if the crowns have surface roughness.;Evaluate differences between the two types of cementing agents, noting if the crowns have anatomically preserved form.;Evaluate differences between the two types of cementing agents, noting if the crowns have secondary caries.	—
