Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Survival rate (%) of translucent zirconia and lithium disilicate ultra-thin veneers. The survival rate is measured considering the period from the cementation of the ultra-thin veneer to the absolute failure of the veneer or censorship. | — |
Secondary
| Measure | Time frame |
|---|---|
| Clinical performance of translucent zirconia and lithium disilicate ultra-thin veneers considering the modified Ryge criteria: color compatibility, surface integrity, marginal integrity and marginal discoloration. The criteria will be classified into three or four ordinal scores, ranging from alpha (no change) to charlie or delta (change considered an absolute failure);Difference in mean of the scores of the modified questionnaire OIDP (Oral Impact of Daily Performances) that evaluates the impact of the treatment in the quality of life of the patients rehabilitated with ultra-thin veneers in translucent zirconia and in lithium disilicate.;Difference in mean of the score of the questionnaire of Aesthetic perception, whose responses of patients rehabilitated with translucent zirconia and lithium disilicate ultra-thin veneers will be measured by the visual analog scale (VAS).;Mean difference in periodontal indexes of patients rehabilitated with translucent zirconia and lithium disilicate ultra-thin veneers. | — |
