    In the last few years, 3D printing for dental applications has notably increased, especially in the areas of oral and maxillofacial surgery, endodontics, orthodontics, prosthodontics, and periodontics. The possibility of individualized dental products drives 3D printing in this area . Metal-, ceramic-, and polymer-based materials are common in the fabrication of dental prosthesis and crowns.

    2012-11-21 · In summary, this work proves that three-dimensional printing of viable cells is possible when this procedure is performed submerged in a high-density hydrophobic fluid. The hydrophobicity and high density of the fluorocarbon helps to control the deposition of each individual droplet, resulting in an optimal final shape and a high degree of precision of the 3D-printed construct.

    2019-4-1 · Three-dimensional printing (3DP) The 3DP method was first devised by Sachs et al. at the Massachusetts Institute of Technology (MIT), who filed a patent for it in 1989 [ 165 ]. Although 3DP can be considered an indirect ceramic inkjet printing process, its distinctive feature is the use of powder beds, which is why 3DP is classified as a powder-based technique in this review.

    Hydroxyapatite (HA) and HA-based nanocomposites have been recognized as ideal biomaterials in hard tissue engineering because of their compositional similarity to bioapatite. However, the traditional HA-based nanocomposites fabrication techniques still limit the utilization of HA in bone, cartilage, dental, applications, and other fields. In recent years, three-dimensional (3D) printing has ...
