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 impl

Example Embodiment

[0047] In an embodiment, there is also provided a method for preparing a tantalum-tantalum-niobium alloy dental implant, including the steps:

[0048] Step 1: Add the tantalum powder with a diameter of 10-60μm and the niobium powder with a diameter of 10-60μm into the mixer according to the ratio of Ta:Nb=5.8~6.2:3.8~4.2, and after thorough mixing, tantalum is formed Niobium alloy dental implant material printing substrate powder.

[0049] Step 2: Reconstruct the dental implant model according to the pre-acquired information on the dental defect.

[0050] Specifically, a three-dimensional dental implant model can be obtained through digital three-dimensional medical assistant software modeling based on the pre-collected oral holographic film and the determined implant plan.

[0051] According to the dental implant model, slice layered cross-sectional profile data is obtained and converted to form a layered structure of the dental implant tissue scaffold model.

[0052] Further, it may ...

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...
