%X This in vitro investigation evaluated how various primers influence the shear bond strength (SBS) and adhesive remnant index (ARI) of orthodontic brackets attached to a reinforced polyetheretherketone (PEEK) substrate. Forty samples were randomly divided into two groups based on the primer used during orthodontic bonding: Group 1 (control)—Transbond XT adhesive with Visio.link primer, and Group 2 (experimental)—Transbond XT adhesive with a conventional orthodontic primer. Following bonding, specimens underwent thermocycling, SBS testing, and ARI assessment after debonding. Statistical analysis was performed using the independent unpaired t-test and Chi-square test. Group 1 showed significantly higher SBS values (21.38 ± 1.48 MPa) than Group 2 (18.63 ± 1.29 MPa) (p < 0.0001). No statistically significant differences were noted in ARI scores or failure mode distribution between the groups. The SBS values from both primers exceeded the clinically acceptable threshold. Thus, both primers demonstrated comparable clinical applicability in orthodontic bonding, particularly in cases where Visio.link may not be readily accessible.
