Assessment of the Accuracy of Bracket Positioning Using Two Different Materials for the Construction of the Indirect Bonding Tray

Research Abstract

Objective: To assess the accuracy of bracket positioning using two different materials for the construction of indirect bonding trays. Materials and Methods: A randomized controlled trial was conducted on 20 patients (200 brackets) divided into two groups. Group A used indirect bonding trays made of transparent flexible silicone (Memosil 2), while Group B used trays made of double-layer thermoformed sheets. Upper teeth (from right to left second premolars) were bonded, excluding molar tubes. Virtual bracket positioning was performed using digital scans and 3D-printed models. Post-bonding accuracy was evaluated by superimposing pre- and post-treatment models and measuring deviations in vertical (occluso-gingival) and horizontal (mesio-distal) directions. Results: Thermoformed trays demonstrated superior vertical accuracy compared to silicone trays. Conversely, silicone trays showed better horizontal accuracy. All measured deviations were clinically acceptable (<0.5 mm). Statistical analysis revealed significant differences between the groups (p < 0.05). Conclusion: The choice of tray material influences bracket positioning accuracy, with thermoformed trays excelling in vertical precision and silicone trays performing better horizontally. Clinicians should consider these trade-offs when selecting tray materials for indirect bonding. Digital workflows enhance reproducibility, supporting their adoption in orthodontic practice.

Tribocorrosion and antibacterial behaviour of boron-embedded oxide coated Ti45Nb by plasma electrolytic oxidation

Research Abstract

ABSTRACT

While titanium alloy biomaterials have moderate overall properties, they are often surface-engineered to enhance corrosion resistance, wear, biocompatibility, and antimicrobial qualities. Among various coating processes, PEO is favoured for its ability to embed ions and nanoparticles into the oxide coating. In this study, Ca, P and B-embedded titania layers were successfully formed on the surface of Ti45Nb substrates using PEO. In order to investigate the effect of the boron amount on tribocorrosion and antibacterial/antimicrobial properties, two different boron contents were used in B-embedded coatings. The results were compared with those of the scientific literature. As a result of XRD analyses, anatase and rutile phases, the two main polymorphs of TiO2, were detected on the substrate surfaces as expected. Ca, P and B ions embedded in the oxide layer were determined by XPS analyses. The simultaneous effects of wear and corrosion in the SBF fluid on the oxide coating with and without B embedment were investigated. At the same time, the impact of the presence of boron ion in the oxide layer and the amount of boron in the electrolyte on antimicrobial/antibacterial properties were analysed.
