“…In the frontomaxillary suture, displacement occurred majorly in the vertical plane causing compression and a more uniform stress distribution which is in accordance with a study by Holberg et al [ 25 ]. In the zygomatico-maxillary suture, sagittal plane displacement was predominant depicting the influence of distalization forces which is concurrent with Pawan Gautam et al [ 16 ].…”

Objectives To three-dimensionally analyse the stress distribution and displacement pattern in the maxillofacial complex following intrusion and distalization of the maxillary arch using finite element analysis in skeletal class II malocclusion with prognathic maxilla and vertical maxillary excess using miniplates and mini-implants. Materials and methods Finite Element models of a skull, Y-shaped stainless steel miniplate, mini-implant and a posted arch were generated. Three force levels (1) 200 g (2) 300 g and (3) 500 g per side were applied to the assembly. The models were pre-processed and the analysis was performed using ANSYS version 18.1 software. Alterations in von mises stress, principal maximum stress, principal minimum stress and compressive stress were analysed around the sutures and surface landmarks. Results With miniplates, there was a maximum stress concentration at the zygomatic buttress with even stress distribution at the fronto-maxillary, zygomatico-temporal, zygomatico-frontal and pterygomaxillary sutures along with anatomical landmarks such as frontal process of maxilla, ANS, Point A, prosthion and maxillary process of zygoma. First molars experienced greater distalization effects with buccal flaring when miniplates were used. With mini-implants, canine and premolars also exhibited greater distalization effects. In the root apices, lateral incisors showed increased lingual root movement with mini-implants. Conclusion Miniplates provide a greater distalizing effect while mini-implants produce increased intrusive effect. The distalizing effect is greater when 500 g of force is applied using miniplates with significantly even stress distribution and displacement pattern.

NiTi alloys are in demand in commercial and biomedical industries. This article discusses Ni-Ti alloy characteristics and applications. Ni-Ti is a smart material that can demonstrate thermal-induced shape memory at lower operational temperatures. Its biomedical applications are described. Biomedical industry end products must pass many biocompatibility testing. Biomedical implants must pass haemocompatibility, lysis and thrombogenicity. All the precise approaches and procedures aid with selection.

“…Unfortunately, evidence shows that orthodontic forces are remarkably variable among the different studies in the literature because it is significantly difficult to accurately estimate the ideal force needed to achieve rapid tooth movement. [1][2][3] However, some studies reported that lower forces could obtain optimal results. On the other hand, it has been…”

Orthodontic treatment is usually conducted by applying forces to certain teeth to move them into a targeted position. Orthodontic wires have been reported to be the primary modalities used in fixed-appliances-based orthodontic treatment to induce favorable tooth movement events. Accordingly, acquiring adequate knowledge about these approaches' clinical applications and biochemical behavior is essential when planning for a successful orthodontic treatment. Orthodontic wires are widely used and are mainly composed of composites, polymers, alloys and metals. Accordingly, the physical properties and clinical application of orthodontic wires vary based on their composition. In this context, it was recommended that achieving favorable outcomes of orthodontic treatment obliges clinicians to decide the best orthodontic wire and treatment plan based on the chemical properties and related clinical applications of each wire. Therefore, wires that tend to produce increasing stiffness gradually are generally used. However, it should be noted that no ideal wire exists. Therefore, favoring the application of a wire over the other should be based on the intended outcomes and stage of the treatment process.
