specific Embodiment approach 1

[0021] Specific Embodiment 1: The dental root implant matrix containing silicon, calcium, phosphorus, and sodium micro-arc oxidation coating in this embodiment is composed of a dental root implant 1 and a clamp 2, wherein the upper end of the dental root implant 1 is provided with a screw The clamp 2 is inserted into the slot 3. The clamp 2 is composed of a screw 4 and a fitting 5. The screw 4 is screwed to the bottom of the fitting 5. A hole 6 is opened at the side end of the fitting 5. The screw 4 is screwed into the screw insertion slot 3.

[0022] In this embodiment, a micro-arc oxidation bioactive coating can be formed on the surface of the dental root implant by a micro-arc oxidation method, and silicon, calcium, phosphorus, and sodium bioactive elements can be introduced into the coating, so that the dental root implant has apatite-induced ability, can effectively shorten the time of implant-osseointegration, and induce the formation of new bone on the root surface. Mus...

Abstract

The invention provides a root of tooth implant matrix containing silicon, calcium, phosphorus and sodium micro-arc oxidation coating and a preparation method thereof, relating to the field of implant material of a dental department. The invention aims at solving the problems that the existing root of tooth implants and metal ions of accessories thereof are easy to dissolve out to cause muscle tissue necrosis and the coating prepared on the surface of the implant through micro-arc oxidation is incomplete. The preparation method comprises the steps of selecting pure titanium or titanium alloy to be processed into the implant matrix and an oxidation fixture, polishing, washing and drying; and preparing the micro-arc oxidation bio-coating with micro-nano porous appearance on the external surface of the implant matrix by utilizing a micro-arc oxidation technology, taking out, washing and drying so as to obtain the root of tooth implant containing silicon, calcium, phosphorus and sodium micro-arc oxidation coating. According to the tooth implant matrix, biological active elements such as silicon, calcium, phosphorus and sodium are introduced into the coating, so that the root of tooth implant has apatite inducibility, the time for combining the implant and the bone is shortened, the part of the surface of the implant, contacted with the muscle tissue, can be completely oxidized due to the design of the fixture, the efficiency is high, no pollution is generated, and the tooth implant matrix is convenient to produce in large scale.

Description

technical field [0001] The invention relates to a dental root implant substrate and a preparation method thereof, in particular to a dental root implant substrate with a silicon, calcium, phosphorus and sodium micro-arc oxidation coating and a preparation method thereof. Background technique [0002] Dental root implants are widely used in the restoration of patients with dentition defects. However, due to the long time of implant-osseointegration, metal ions are easily dissolved and cause muscle tissue necrosis, resulting in failure cases, which greatly limits its wide application. The micro-arc oxidation method can be used to generate a bioactive coating on the surface of the implant, thereby improving the biological properties of the implant material. While inhibiting the dissolution of metal ions, it can also induce the formation of apatite, so that the implant has biological activity. However, usually in the micro-arc oxidation preparation process, the fixture needs to...
