Conditions
Interventions
Prospective randomized clinical trial, triple blind (patient, operator and examiner).
Method of data analysis: The data evaluated against the primary and secondary outcomes will be analyzed regarding
significance level of alfa = 0.05
test power of 80%
expected 5-year survival rate of 92%, and sample loss of 20% the sample calculation was set at n = 40 per group, totaling 80 teeth. Patients will sign an informed consent form – TCLE before starting t

| Want to evaluate the color change and marginal pigmentation of printed crowns cemented on teeth (primary outcome) This clinical study is expected to verify whether different brands used to obtain complete crowns in CAD/CAM system by 3D printing have the same clinical performance and satisfaction , using modified USPSH criteria to assess the longevity of restorations, assess patient satisfaction with rehabilitation using the EVA scale, as well as operator satisfaction with rehabilitation. The assessment of survival of restorations in a minimum period of 5 years. The follow-up will be carried out in 7 moments: immediate (T0), 6 months (T1), 1 year (T2), 2 (T3), 3 (T4), 4 (T5) and 5 years (T6). The data obtained from the primary outcomes will be statistically analyzed for normal distribution and homoscedacity, and then an appropriate statistical test will be used to analyze the outcomes as a function of the evaluation periods (alfa = 0.05) | — |

| Want to evaluate the dental fracture of the remnants where the impression crowns were cemented It is expected in this clinical study to verify whether different brands used to obtain full crowns in CAD/CAM system by 3D printing have the same clinical performance and satisfaction, using the modified USPSH criteria to evaluate the longevity of restorations, patient satisfaction in relation to rehabilitation using the EVA scale, as well as the operator's satisfaction with the rehabilitation. The evaluation of the survival of the restorations in a minimum period of 5 years. The follow-up will be carried out in 5 moments: 2 years (T3), 3 years (T4), 4 (T5) and 5 years (T6). The data obtained from secondary outcomes will be statistically analyzed for normal distribution and homoscedacity, and then an adequate statistical test will be used to analyze the outcomes as a function of the evaluation periods (alfa = 0.05);Want to evaluate the color change of the cement-retained restoration It is expected in this clinical study to verify whether different brands used to obtain full crowns in CAD/CAM system by 3D printing have the same clinical performance and satisfaction, using the modified USPSH criteria to evaluate the longevity of restorations, patient satisfaction in relation to rehabilitation using the EVA scale, as well as the operator's satisfaction with the rehabilitation.
