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.

The article presents an analysis of the design assumptions innovative implant-scaffolds developed by Authors, which constitute alternative to implantation directly after tooth extraction for typical screw implants designed according Brannemark concept.The scope work was divided into modelling using digital twin method and manufacturing these implantable elements in real conditions. The computational bone base models obtained create a conditions prevailing oral cavity presented finite element FEM state installation patient's under different occlusal performed determine maximum loads compare them with strength properties manufactured selective laser sintering from TiAl4V6 Extra Low Interstitials (ELI) grade 23 alloy.The results simulation studies when loading bone-implant-scaffold model forces integrated prosthetic crown abutment-screw illustrate stress distribution occurring entire system, particular those acting on implant-scaffold. Extreme cases cusp at angles 0, 15, 30 degrees 200, 500 or 1500 N were taken account, simulating average masticatory muscles case external impact adopted system. confirms that use new additive technology introduction unique geometric features guarantees correct transfer bone-implant system various load situation premature contact, is usually critical durability implant-prosthetic restoration.In subsequent studies, Authors plan this bone-screw implants, abutments, crowns concept. This will allow determination optimal parameters individual solutions depending clinical types teeth.The implant-scaffold, thanks connector placement supragingival zone can easily without damaging even force applied destroying its structure. simulates extreme cause break. Despite this, implant-scaffold not be damaged. Therefore, confirm (SLS) high surrounding tissues obtained.An original patent construction developed, particularly useful immediate same procedure damaged natural extracted. Optimization their selection, especially power, enables precise reproduction specific project. In particular, possibilities technology, method, allows spot diameter 30-40 micrometres single layer height 25 micrometres, achieving print accuracy concerning project error exceeding 50 making production dental implants.
