Eligibility
Age
18 Years to 60 Years
Inclusion criteria
Inclusion criteria: Participants aged 18 to 60, no specific gender; who have indication for full crowns on posterior permanent teeth; who are available to clinical monitoring throughout the evaluation period; willing and able to go through periapical/interproximal radiographic examination when necessary; be in accordance with the Terms Free and Informed Consent (TCLE); general health consistent with the period of clinical assessment; adequate maxillomandibular relationship and occlusal stability
Exclusion criteria
Exclusion criteria: History of allergy to any of the materials to be used in the search; pregnancy at the beginning of the experiment; use of drugs that may interfere with the environment oral; systemic diseases with the possibility of altered immunity and risk of infection in the start of study; impossibility of being subjected to specific techniques for carrying out the search; insufficient space for proper creation of crowns; habit holders parafunctional; abutment teeth that, endodontically and periodontally, do not present predictability until the end of the evaluation period; periodontal disease; high risk of caries; unsatisfactory oral hygiene; use of removable partial dentures
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Zirconia-reinforced lithium silicate ceramic crowns as expected deliver superior performance similar to that of lithium disilicate crowns. Being made by the system CAD/CAM, present better marginal adaptation and in addition the use of monolithic materials eliminates one of the failure factors of bilayer ceramic restorations (chipping of the covering ceramic). | — |
