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.
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).

The uppethat consists of positioning brackets on a study model and they will be extended to the patient's mouth. .r hemiarch of each patient will be randomly placed to be cemented with a transfer tray made of polyvinylsiloxane thermal glue, by means of the indirect technique

Linear mesio-distal position
It is the difference in the maximum Euclidean distance (two-dimensional plane) between a point mesial and distal of the bracket in the working model and in the patient's tooth.
Time frame: 2 weeks
Linear occlusal-gingival position
It is the difference in the maximum Euclidean distance (two-dimensional plane) between a point occlusal and gingival of the bracket in the working model and in the patient's tooth.
Time frame: 2 weeks
