Problems solved by technology

The disadvantage of this kind of dental implant is that the porous material used in the dental implant is a single-space material, and the cavity wall of the hole is still a dense material. It may be lower, but due to the large elastic modulus of the dense material of the cavity wall, it is difficult for the cells on the cavity wall of the porous material to feel the stimulation of the force, and stress shielding occurs, which is not conducive to cell growth. Dental implants and The fusion of the surrounding bone tissue is slow, which is not conducive to the regeneration of bone tissue. The interface between the dental implant and the adjacent bone tissue is not firm and will loosen
[0005] But, the bonding strength of existing helical dental implant and alveolar bone is not increased; Although other leaf-shaped or heterosexual dental implants have a structure in which the body part protrudes into the alveolar interior, it increases the bonding strength between the dental implant and the tooth. The bonding strength of the groove bone, but also increases the difficulty of installation and the size of the wound. In addition, when there is a problem with the dental implant and needs to be taken out again, it increases the difficulty of the operation

preparation example Construction

[0047] In one embodiment, a method for preparing a tantalum-tantalum-niobium alloy dental implant is also provided, comprising the steps of:

[0048] Step 1: Add tantalum powder with a diameter of 10-60 μm and niobium powder with a diameter of 10-60 μm into the mixer according to the ratio of Ta:Nb=5.8~6.2:3.8~4.2, and mix them thoroughly to form tantalum Niobium alloy dental implant material printing base powder.

[0049] Step 2: Reconstruct the dental implant model according to the pre-collected oral tooth defect information data.

[0050] Specifically, a three-dimensional dental implant model can be obtained by modeling with digital three-dimensional medical assistance software according to the pre-collected oral holographic film and the determined implant plan.

[0051] According to the dental implant model, slice layered cross-sectional profile data are obtained and transformed into the dental implant tissue scaffold model into a layered structure.

[0052] Further, it ...

Abstract

The invention provides a tantalum niobium alloy dental implant which comprises an artificial tooth base station portion, a main body portion and a neck connecting the artificial tooth base station portion with the main body portion. The outer surface of the main body portion is provided with an external thread contacting with alveolar bone, and multiple through holes penetrating thread ribs and parallel to the main body portion are formed in the thread ribs of the external thread at intervals; each thread rib further comprises two side faces in opposite arrangement, each side face is coated with a decomposable film, and a hyperostosis helping slow-release agent is contained in a containing cavity jointly formed by the two decomposable films and the corresponding through holes. The tantalumniobium alloy dental implant has the advantage of being good in combining with the alveolar bone and easy to mount and demount.

Description

technical field [0001] The invention relates to the technical field of rehabilitation chairs, in particular to a traditional Chinese medicine rehabilitation chair for hip joint rehabilitation. Background technique [0002] In recent years, with the development of dental implant technology, dental implants have become one of the main restoration methods for missing and defective dentition. Dental implants are usually anchored on one or more edentulous parts in the patient's dentition. Generally, dental implants are screwed or press-fit into holes in patients whose original teeth have been lost or damaged, and the holes are drilled in the mandible or maxilla of the patient's edentulous site. Generally, implant placement only takes tens of minutes to several hours to complete. Due to the selection of biomaterials with excellent compatibility with the human body, dental implants do not produce any adverse side effects on the human body. [0003] In the past 20 years, many univ...
