Clinical Trial Summary

The aim of this study is to evaluate the wear produced in the short and medium term by monolithic zirconia, metal-ceramic and lithium disilicate restorations on the antagonist natural enamel in patients with fixed prostheses, assessing the factors that may influence this wear. The investigators will also analyse whether the wear of the tooth antagonistic to the different restorations differs significantly with respect to the wear of the natural tooth (control group). The null hypothesis is that there are no significant differences.

Treatment with lithium disilicate restorations
Treatment with lithium disilicate restorations on teeth (single crowns). The sample (75 patients) will be divided into three groups according to the ceramic material used: monolithic zirconia, lithium disilicate and metal ceramic.
Treatment with metal ceramic restorations

Outcome

Type Measure Description Time frame Safety issue
Primary Enamel volume loss Analyse volume loss of enamel antagonist to monolithic zirconia, lithium disilicate and metal ceramic restorations. The investigators will also analyse whether the wear of the tooth antagonistic to the different restorations differs significantly with respect to the physiological wear of the natural tooth (control group). Through study completion, an average of two years
Secondary Survival To compare the survival between monolithic zirconia, lithium disilicate and metal ceramic restorations. Through study completion, an average of two years
