Patients from the self-ligation clinic who meet the inclusion criteria will be invited to participate and sign the informed consent. For the cementation of the brackets in each patient, the upper arch (right and left) will be divided from the second premolar on the right side to the second premolar on the left side, randomly assigned, to be cemented with a polyvinylsiloxane transfer tray and the other with thermal glue (materials selected for the study).
Objective: To compare the cementation precision of self-ligating brackets between two indirect bonding materials: polyvinylsiloxane and thermal glue.~Methods: Split-mouth randomized clinical trial study, with 15 participants. The study will be divided into two groups, Group 1: Polyvinylsiloxane and Group 2: Thermal glue.
