Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ultrasonic tips
Prepared surfaces will be finished with ultrasonic tips
Ultrasonic tips
These tips are going to be used to give the final shape of the prepared surfaces before taking the impression for the construction of the veneers.
Conventional
Prepared surfaces will be finished with ordinary burs
