Problems solved by technology

[0007] In addition, the disadvantage of existing root-type implants is that the initial fixation force can only be weak if the implant is implanted into the alveolar without additional bone removal but exerts pressure on the implant fixture.
In particular, if the tooth needs to be extracted due to severe periodontitis, the depth of the alveolar bone is very low and the existing root type implant cannot be directly applied
As a result, the existing root-type implants are suitable for tooth extraction with healthy alveolar bone, and can only be used in limited cases
In addition, regarding the upper restoration, there is no technical reminder on the connection method. If the design form is expected to be made, it is estimated that only the prosthesis in the bonded form can be used
In particular, there are no detailed technical tips on how to make the shape of root-type implants, which reduces the specificity of the practical method of existing root-type implants, and there are few examples of actual operations

Embodiment Construction

[0038] The personalized and customized dental implant fixture and its manufacturing method of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] figure 1It is a graph comparing the case (a) of healthy teeth and the case (b) of teeth with periodontal disease according to the present invention. The case (b) of a patient with severe periodontitis is different from the case of healthy teeth (a) in that the height of the alveolar bone is low, and the alveolar bone AB surrounding the natural tooth NT is also in a weakened state. Even if the tooth is extracted in this state and an implant in the shape of the tooth NT is immediately implanted, the depth and area covering the tooth NT after tooth extraction are shallow and small, and it is difficult to ensure the initial fixation force of the implanted tooth. The personalized and customized dental implant fixture of the present invention provides an initial fixation force that...

Abstract

The present invention relates to a custom implant fixture which may comprise: a first fixture part having a first transverse section determined by a shape covered by an alveolar bone of a tooth to be extracted; and a second fixture part formed so as to extend from the first fixture part, determined from the position and the direction of a root portion of the tooth with respect to the alveolar bone, and having a second transverse section.

Description

technical field [0001] The invention relates to a personalized customized dental implant fixture with natural tooth root shape, a manufacturing method thereof and a customized dental implant system using the same. Background technique [0002] In dentistry, a dental implant is a treatment in which artificial teeth are placed in place of missing teeth to make them look like real teeth. The traditional dental implant method implants a fixture made of osseointegration (Osseointegration) material into the alveolar bone through surgery to replace the missing tooth and fix the artificial tooth on its upper part. [0003] The traditional fixation device implantation method is to form a rotationally symmetrical hole in the bone by cutting the alveolar bone, and then insert an implant of suitable size. Rotationally symmetrical implant fixtures made in a variety of shapes, diameters and lengths adhere to the alveolar bone over several weeks after implantation. [0004] In this type ...
