Abstract
The invention discloses an improved artificial dental implant. The improved artificial dental implant is characterized in that the implant is produced by CNC (computer numerical control) processing, and a medical porous lamina is formed on the corresponding surface, contacting with an alveolar bone of a patient, of the implant through material increase manufacturing. Strength and mechanical property of the implant are guaranteed by CNC processing, the optimal diameter of the medical porous lamina is customized through material increase manufacturing, and accordingly, bone attachment or ingrowth is facilitated to the greatest extent. The improved artificial dental implant is particularly suitable for filing up positions of missing teeth in case of agomphosis.
Description
Technical field
What the present invention relates to is a kind of artificial dental implant of improvement, belongs to technical field of dental implantation.When being specially adapted to agomphosis, fill up scarce placed artificial implant.
Background technology
Artificial dental implant is body implant, and for implanting the artificial alternative of alveolar bone during human body agomphosis, make patient recover the physiological function of tooth to a great extent, improvement is chewed, and improves the quality of living.
In prior art, artificial dental implant is processed into by CNC, after through sandblasting acid etching implant (1) surface formed thin porous layer, or hydroxyapatite or titanium are formed thin porous layer by thermal spraying on implant (1) surface, or forming thin porous layer by oxidation on implant (1) surface, being also made into integration artificial dental implant and porous surface thin layer by increasing material manufacture.But by the artificial dental implant that CNC is processed to form, the aperture on its surface is difficult to customization, is unfavorable for that the quick bone at initial stage depends on or Bone Ingrowth, after using certain hour, has loosening possibility, adds the mortality of replacement, the physiological load of making patients.The artificial dental implant be made into integration by the manufacture of increasing material is inadequate because of manufacturing technology Maturity, can not ensure mechanical property and the mechanical strength of implant, causes the risk having fracture and second operation in implant.
Summary of the invention
The object of the present invention is to provide a kind of artificial dental implant of improvement, under the prerequisite ensureing mechanical property and mechanical strength, the aperture with Bone Ingrowth can be depended on for the most applicable bone of implant customization, overcome the defect easily loosening and may rupture after existing artificial dental implant is implanted.
Task of the present invention realizes by this way:
A kind of artificial dental implant, is first processed into by CNC, then is manufactured on implant (1) surface formation porous medical metal thin layer (2) by increasing material, and customizes optimum aperture for this thin porous layer.
Can according to the alveolar bone difference of patient and biomechanics requirement, for patient customizes coverage rate and the aperture of thin porous layer.
Porous medical metal thin layer (2) is distributed in the respective surfaces that implant (1) contacts with patient's alveolar bone, can cover the surface of 1% ~ 99%;
The average pore size scope of porous medical metal thin layer (2) is 1 ~ 999 micron.
Advantage of the present invention is: the present invention is processed into artificial dental implant by CNC, ensure that intensity and the mechanical property of implant.Be fabricated to porous medical metal thin layer (2) by increasing material again and customize optimum aperture, bone can be conducive to substantially and depend on and Bone Ingrowth.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation (wherein thin porous layer is distributed in the part surface of implant).
Detailed description of the invention
As shown in Figure 1, the invention provides a kind of artificial dental implant, be processed into by CNC.Then set up the model with the thin porous layer in optimum aperture (such as 200 microns) in a computer, then by laser or high-power electron beam melting medical metal powder, this artificial dental implant obtains required thin porous layer.
Claims (1)
1. the artificial dental implant of band thin porous layer improved, is characterized in that being processed into by CNC, then is manufactured on by increasing material the respective surfaces that implant (1) contacts with patient's alveolar bone and forms porous medical metal thin layer (2); The coverage of this porous medical metal thin layer (2) can customize, and is distributed in the respective surfaces that implant (1) contacts with patient's alveolar bone, can covers the surface of 1% ~ 99%; The aperture of this porous medical metal thin layer (2) can customize, and average pore size scope is 1 ~ 999 micron.
