Abstract

The invention relates to the technical field of a medical biomaterial, and particularly relates to an orthopedics or dental filling material. The invention provides an orthopedics or dental filling material, a dental implant and a degradable artificial bone, which aim at solving the defects that the existing dental filling material cannot promote fast restoration of tooth tissues, a bone filling material is insufficient for the inducibility of new bones and the bone forming process is slow. The filling material comprises a stent, and an active factor is attached to the stent; the stent comprises a stent body which is made of hydrogel materials, and hydroxyapatite is deposited on the stent body; and the concentration of the stent is 0.000001-100mg/cm<3>. The orthopedics or dental filling material has stronger capability of inducting the formation of new bones, as well as good bone defect repair capability, and strong capability of promoting the formation of tooth tissues.

Description

technical field [0001] The invention relates to the technical field of medical biomaterials, in particular to an orthopedic or dental filling material, a dental implant and a degradable artificial bone. Background technique [0002] According to relevant statistics, the incidence rate of dental caries in the population of our country is 37%, with an average of 2.47 dental caries per person. There is a great demand for filling materials for repairing dental caries, and the estimated annual demand is about 1 ton. However, none of the currently used dental filling materials can promote rapid restoration of tooth tissue. Moreover, with people's pursuit of high-quality life, when teeth fall off, people usually plant dentures again. Based on the above-mentioned needs of people, relevant manufacturers provide multiple dental implants. A dental implant is composed of a base, a neck, and a body. In the structure of the dental implant, the base refers to the part where the dental i...
