“…However, due to the low amount of carboxyl groups in the monomers, there is no chemical bonding with the enamel. As a result, the enamel must be conditioned beforehand and a dry working field is necessary ( 3 , 7 , 20 ).…”

Background Adequate bracket-enamel bonding is critical to prevent detachment during orthodontic treatment and minimize any potential delay in results. The aim was to compare the shear bond strength of three metal bracket base designs: laser-structured base, mesh base, and retention grooves base. Material and Methods In this experimental in vitro study, 54 human premolars were immersed for one week in 0.1% thymol solution, then placed in distilled water with weekly replacement until the start of the study. The premolars were cemented with brackets of varying base designs: A. Discovery® Smart (laser structured), B. Mini Master® Series (base with mesh), and C. Roth Max (base with retention grooves). All brackets were cemented using TransbondTM XT. A universal testing machine was used to evaluate the shear bond strength at a crosshead speed of 0.75 mm/min. Welch’s one-factor ANOVA with robust variance and Tukey’s post hoc test were used to compare means, with a significance level of p <0.05. Results The average shear bond strength values were for the bracket with laser-structured base (14.78 ± 5.79 MPa), the bracket with mesh base (9.64 MPa ± 2.54 MPa) and the bracket with retention groove base (15.38 MPa ± 2.67 MPa). It was found that brackets with mesh bases had significantly lower shear bond strength than brackets with laser-structured bases ( p =0.001) and brackets with retention grooves bases ( p <0.001). No significant differences were observed between the latter two types of brackets ( p = 0.893). Conclusions The bracket base design influenced in vitro shear bond strength with significantly higher values observed for Roth Max and Discovery® Smart brackets compared to Mini Master® Series brackets. Key words: Shear strength, laser-structured bracket, bracket with mesh base, bracket with retention groove base.

“…( 4 ) and Morales et al . ( 7 ) propose a range of 6 to 8 MPa. It has also been found that values above 20 MPa to 40 MPa may increase the risk of enamel breakage due to exceeding the cohesive forces of the adamantine structure ( 8 , 9 ).…”

“…Bonding orthodontic brackets clinically is of paramount importance for the overall effectiveness of orthodontic treatment [ 1 ]. In the past few years, adult orthodontic treatment has gained popularity [ 1 , 2 , 3 ]. Accordingly, there may be clinical scenarios in which orthodontic brackets are bonded to prosthetic or restorative surfaces.…”

“…When a fixed dental prosthesis is planned for an orthodontic patient, it is typically recommended that the insertion of the final prosthetic restoration be delayed until the completion of orthodontic therapy [ 1 ]. This delay permits the tooth to be repositioned to its final position after orthodontic treatment is completed before placing the final restoration [ 2 , 3 ]. In addition, any surface damage to the fixed restoration upon removal of bonded orthodontic brackets may necessitate replacement of the fixed dental restoration [ 3 ].…”

This in vitro study assessed the effect of different primers on the shear bond strength (SBS) and adhesive remnant index (ARI) of orthodontic brackets bonded to reinforced polyetheretherketone (PEEK) substrate. A total of 40 specimens were randomly distributed to two groups based on the primer used for orthodontic bonding: group 1 (control)—Transbond XT adhesive with Visio.link primer and group 2 (test)—orthodontic adhesive (Transbond XT) with traditional orthodontic primer. After bonding, specimens were thermocycled followed by SBS testing and ARI scoring of debonded specimens. Data were analyzed using the unpaired independent t-test and the Chi-square test. Group 1 specimens showed significantly higher SBS values (21.38 ± 1.48 MPa) compared to group 2 specimens (18.63 ± 1.29 MPa) (p < 0.0001). Adhesive remnant index scores showed no significant variations in bond failure modes and distributions between groups. The SBS obtained by the tested primers exceeded the clinically recommended value. Consequently, there is a comparable clinical application for both tested primers in orthodontic bonding, especially the traditional orthodontic primer, where the availability of Visio.link in clinical practice is not ensured.
