@#How to obtain ideal
regeneration of periodontal
tissue remains a challenge in the clinical
treatment of
periodontitis.
Three-dimensional printing technology is based on
computer-aided design, which produces materials with specific 3D shapes by layer-by-layer superposition, and has been applied to periodontal
tissue regeneration therapy, this
method offers
hope to achieve ideal periodontal
regeneration. This article reviews the application of
3D printing technology in the field of periodontal
tissue regeneration. The
literature review results show that
3D printing technology can design three-dimensional structures using
computer software in advance and produce materials with specific three-dimensional structures.
3D printing technology mainly includes selective
laser sintering, selective
laser melting, extrusion forming
printing and
3D bioprinting. At present, the support materials prepared by
3D printing technology include
ceramic materials,
polymer materials and
metals. Submaterials have been extensively studied given their high adjustability, and 3D-printed personalized
titanium mesh has been applied in the clinic. Multiphase materials prepared by 3D-
printing technology can regenerate periodontal
tissue in
animal experiments, but the effect is not good in
patients with
periodontitis. In addition,
3D printing of composite scaffolds for periodontal
tissue regeneration need to be further studied.
