Hybrid Biomechanical Design of Dental Implants: Integrating Solid and Gyroid Triply Periodic Minimal Surface Lattice Architectures for Optimized Stress Distribution

Journal of Functional Biomaterials, Год журнала: 2025, Номер 16(2), С. 54 - 54

Опубликована: Фев. 9, 2025

Background: Dental implantology has evolved significantly since the introduction of additive manufacturing, which allows for reproduction natural bone’s porous architecture to improve bone tissue compatibility and address stress distribution issues important long-term implant success. Conventional solid dental implants frequently cause shielding, compromises osseointegration reduces durability. Aim: The current research proposes examine biomechanical efficacy fully hybrid gyroid triply periodic minimum surface (TPMS) latticed across different cell sizes optimize Methods: This study evaluates six implants, including designs with three sizes—FLI_111 (1 mm × 1 mm), FLI_222 (2 2 FLI_333 (3 3 mm)—and TPMS necks in corresponding sizes—HI_111, HI_222, HI_333. To enhance initial stability, a square-threaded design was added into bottom part both lattice implants. also incorporate anti-rotational connections fixation, they undergo clinical viability comparison contemporary designs, finite element analysis (FEA) utilized through nTopology (nTOP 4.17.3) balance stiffness flexibility. mechanical performance under realistic conditions, dynamic mastication loading simulation conducted 1.5 s cycles. Results: findings reveal that particularly exhibited improved characteristics by reducing micromotions at bone–implant interface, improving osteointegration, attaining better distribution. Conclusions: By addressing shielding boosting performance, this work paves way personalized developing technology, results.

Deformation behaviour, limitations in design, applications, and additive manufacturing of hierarchical honeycombs

Manufacturing Review, Год журнала: 2025, Номер 12, С. 3 - 3

Опубликована: Янв. 1, 2025

Hierarchical honeycombs are particularly useful in aerospace industries because of their capability to overcome challenges related bend-dominated behaviour. These structures ideal for aeronautical applications capacity integrate lightweight design, good mechanical properties, and efficient load distribution. However, the efficacy under applied loads is influenced by type polygon cell typically introduced parent hollow structure. The current literature has gaps knowledge regarding highest order hierarchy that can practically be achieved hierarchical with different shapes at vertices or walls. This review paper documents work carried out on examine behaviour how they efficiently designed. first section highlights deformation use today. next contains a discussion constraints determining attainable honeycombs, geometric parameters. followed relevant hierarchically built honeycomb parts industries. efficacy, as well using additive manufacturing building then highlighted. Alternatives future studies advances sector addressed last paper.

Finite Element and Machine Learning-Based Prediction of Buckling Strength in Additively Manufactured Lattice Stiffened Panels

Metals, Год журнала: 2025, Номер 15(1), С. 81 - 81

Опубликована: Янв. 17, 2025

The current research aimed to investigate the critical buckling load of a simply supported aerospace-grade stiffened panel made additively manufactured cubic lattice unit cell arrays, namely simple cubic, face-centered (FCC) and body-centered (BCC) structures. Ansys Design Modeler was chosen design analyze panel, while popular material, Ti-6Al-4V, used as build material. Numerical validation on both beam structure established from multiple resources literature. Finally, panels were tested against increments strut diameter ranging 0.5 mm 2 mm, which corresponds relative density 6% 78%. It found that considering fixed density, outperformed results FCC BCC panels. Moreover, relationship parameters be non-linear. data samples collected numerical outcomes utilized train four different machine learning models, multi-variable linear regression, polynomial random forest regressor K-nearest neighbor regressor. evaluation metrics suggest regression provides highest accuracy among all with lowest mean squared error (MSE) value 0.0001 perfect R2 score. opens up discussion using cells potential structures for future
