Document Type and Number:
WIPO Patent Application WO/2019/218583
Kind Code:
A1
Abstract:
A porous dental implant internally combined with a biodegradable magnesium alloy and a manufacturing method therefor. A dental implant comprises a main body (1) and an embedded body (2). The main body (1) is composed of a bone grafting section (1) and a transgingival section (12), and the side wall of the bone grafting section (11) is provided with threads; the embedded body (2) is a cylinder made of a biodegradable magnesium alloy material, and the surface of the embedded body is provided with external threads; an internal threaded hole allowing the embedded body (2) to be screwed in is formed at the bottom end of the bone grafting section (11), and a plurality of permeating holes (111) are also formed at the bone grafting section (11); and one end of each permeating hole (111) is communicated with the internal threaded hole, and the other end of each permeating hole (111) is communicated with the side wall of the bone grafting section (11). By means of the dental implant, under the condition that the porosity of the dental implant is ensured, the mechanical properties and strength of the dental implant are ensured. The magnesium alloy and the dental implant are mechanically connected by means of threads, the operation is simple, and the connection is stable and reliable. After implantation, the magnesium alloy degrades automatically, and bone cells are induced to grow into the dental implant to finally result in synostosis. In the degradation process of the magnesium alloy, the mechanical properties of the dental implant meet the working requirements all the time.
