Název v původním jazyce

Trabecular Structures as Efficient Surface of Dental Implants

Popis výsledku v původním jazyce

Fast development of additive methods provides production of advanced porous structures which form external layers of implants. Since implants usually replace part of missing or damaged bone, it is appropriate that its external layers are close to bone structure. Today, most of the porous structures which are used for implants are trabecular structures, composed of beams. Design of the structures depends on a type of implants, width of layer et al. Small implants, as dental implants, have very thin external layers (~ 200 µm), which means that the structure is very fine. The quality of 3D printed structures therefore depends heavily on accuracy of current 3D printers (SLM method). Problems of 3D printing which can lead to implant failure are cracks of beams, its poor interconnection, etc. The study is focused on the quality control of 3D printed trabecular structures, especially with respect to implant stability in bones and minimization of a risk of the structure damage. The quality of the structures was evaluated by an optic and microscopic analysis using SLM. Based on the results, we suggest substitution of the trabecular structures by a gyroid structure composed of a system of walls. Gyroid structures are not so prone to local discontinuities and have other advantages such as elimination of sharp corners and edges, which contribute to better proliferation of bone cells.
