DETAILED DESCRIPTION OF THE INVENTION

[0045] Hereinafter, the applicant will describe configuration according to the present embodiments with reference to accompanying drawings.

[0046] In the following description, if generally-known functions and structures are determined as making the subject matters of the present invention unclear, the detail of the generally-known functions and structures will be omitted.

[0047] An integral-type implant 900 according to the present invention includes an intraosseous implant part 100 provided integrally with a lower portion of the integral-type implant 900 and buried in an alveolar bone 810, a gum penetration part 310 provided integrally with an upper portion of the intraosseous implant part 100 and buried in a gum 800 to cover the alveolar bone 810, a prosthetic appliance attachment part 330 provided integrally with an upper portion of the gum penetration part 310 to attach a final prosthetic appliance 700, which is molded in a dental technical laboratory or formed in CAD/CAM, thereto, and a prosthetic appliance attachment central hole 500 having a through hole extending from an upper end surface of the prosthetic appliance attachment part 330 toward the intraosseous implant part so that the final prosthetic appliance 700 is attached to an inner surface of the through hole.

[0048] The intraosseous implant part 100 of the integral-type implant is buried into the alveolar bone 810 to serve as a root of a tooth, and provided an outer portion thereof with a concavo-convex pattern such as a thread to prevent the intraosseous implant part 100 from deviating from the alveolar bone 810 after the implant has been treated.

[0049] The gum penetration part 310 is integrally formed with an upper portion of the intraosseous implant part 100, and has a height of 0.3 mm to 8 mm preferably.

Four or less prosthetic appliance attachment central holes are formed. An entrance diameter of the central hole is equal to or greater than a bottom diameter of the central hole. The prosthetic appliance attachment central hole has a depth of 1.5 mm to 15 mm. The linear distance between the entrance of the prosthetic appliance attachment central hole 500 and the upper end of the outer circumferential surface of the prosthetic appliance attachment part 330 is preferably formed in the range of 0.2 mm to 3 mm as shown in FIG. 10.

[0054] In addition, the prosthetic appliance attachment part may preferably include at least one cutting part, an anti-rotational surface, and anti-rotational groove in order to prevent the rotation of the final prosthetic appliance 700, which is attached, when the prosthetic appliance attachment central hole 500 and the horizontal section of the outer portion of the prosthetic appliance attachment part 330 have a circular shape.

[0055] The implant treatment procedure according to the configuration is as follows.

[0056] 1. The intraosseous implant part of the integral-type implant is buried in the alveolar bone.

[0057] 2. A provisional prosthetic appliance is attached for a predetermined time until implant osseointegration is achieved and the gum is cured.

[0058] 3. An impression work is performed to manufacture the final prosthetic appliance after the provisional prosthetic appliance has been removed

[0059] 4. The final prosthetic appliance is formed in the dental technical laboratory or formed in CAD/CAM based on the relationship between surrounding teeth.

[0060] 5. The final prosthetic appliance, which is formed, is attached to both of the prosthetic appliance attachment part and the inner surface of the prosthetic appliance attachment central hole.

[0061] Although the exemplary embodiments of the present invention have been described, it is understood that the present invention should not be limited to these exemplary embodiments but various changes and modifications can be made by one ordinary skilled in the art within the spirit and scope of the present invention as hereinafter claimed.

[0062] The present invention provides an integral-type implant having a structure allowing the attachment of the final prosthetic appliance provided in various shapes in match with the relationship with surrounding teeth in the state that a prosthetic appliance attachment part is not milled, and preventing the final prosthetic appliance from deviating from the positions thereof by masticatory pressure after the attachment is performed, so that the present invention has industrial applicability.
