BOLT-TYPE IMPLANT

Abstract

A bolt-type implant includes: a bolt (12) configured to be inserted into a vertical hole drilled in a mandible (including an alveolar bone) at a position in which the implant will be placed; a nut (20) configured to be fitted to the bolt inserted into the mandible and fix the bolt to the mandible (including the alveolar bone); and an abutment (11) formed on a bolt head of the bolt so as to constitute a single body with the bolt and configured to be connected to a crown (artificial tooth).

Claims

1. A bolt-type implant which is a dental implant, the bolt-type implant comprising: a bolt (12) configured to be inserted into a vertical hole drilled in a mandible (including an alveolar bone) at a position in which the implant will be placed; a nut (20) configured to be fitted to the bolt inserted into the mandible and fix the bolt to the mandible (including the alveolar bone); and an abutment (11) formed on a bolt head of the bolt so as to constitute a single body with the bolt and configured to be connected to a crown (artificial tooth).

Description

DESCRIPTION OF DRAWINGS

[0015] FIG. 1 is a perspective view of a bolt-type implant that includes an implant main body (10) and a nut (20).

[0016] FIG. 2 is a cross-sectional view of a hole drilled in the mandible (including an alveolar bone) using a drill in order to place the bolt-type implant. (The size (diameter) of the hole is larger at the top and the bottom than in the middle because a bolt head (12a) is inserted through the top and the nut (20) is inserted through the bottom).

[0017] FIG. 3 is an overall cross-sectional view of the bolt-type implant after the implant treatment is completed.

DESCRIPTION OF REFERENCE NUMERALS

[0018] 10: implant main body (refers to a single body formed by combination of an abutment and a bolt)

[0019] 11: abutment

[0020] 12: bolt

[0021] 12a: bolt head

[0022] 12b: bolt body

[0023] 12ba: screw portion formed at the end of the bolt body

[0024] 20: nut

[0025] 20a: groove formed in the nut (groove used when screwing or unscrewing the nut using a driver)

[0026] 30: crown (artificial tooth)

[0027] 50: hole drilled in the mandible to insert a bolt-type implant

[0028] 50a: top portion of the hole (50) drilled in the mandible where the size (diameter) of the hole is increased to insert the bolt head (12a)

[0029] 50b: bottom portion of the hole (50) drilled in the mandible where the size (diameter) of the hole is increased to insert the nut (20)

[0030] 101: gum

[0031] 102: mandible (including an alveolar bone)

[0032] 103: skin under the mandible

BEST MODE OF THE INVENTION

[0033] A bolt-type implant according to the present invention includes an implant main body 10 and a nut 20.

[0034] Also, the implant main body 10 is divided into an abutment 11 and a bolt 12, but the abutment and the bolt are connected and constitute a single body.

[0035] The abutment is formed to be connected to an upper portion of a bolt head 12a.

[0036] Regarding functions of components, the bolt and the nut serve to fix the entire implant to the mandible, and the abutment serves to connect a crown (artificial tooth) to the bolt and support the crown.

[0037] In the drawings, the shape of the abutment is illustrated on the assumption that the crown is connected to the abutment using a method commonly used during a conventional implant treatment, that is, a method in which the crown is connected to the abutment after an adhesive is applied to the abutment.

[0038] Methods other than using an adhesive may also be considered for attaching the crown to the abutment, but detailed descriptions thereof will be omitted because such methods are irrelevant to the gist of the present invention, and any method may be used as long as the abutment is able to be connected to the crown and support the crown.

Embodiment

[0039] Steps for placing the bolt-type implant will be described with reference to the drawings.

[0040] First, the implant main body 10 and the nut 20 are prepared.

[0041] Second, a gum at a position where the implant will be placed and skin under a mandible 102 which is under the gum are cut.

[0042] Third, a vertical hole 50 is drilled in the mandible 102 using a drill, and top and bottom portions 50a and 50b of the drilled hole 50 are made larger using a drill.

[0043] This is to allow the bolt head 12a to be inserted through the top portion 50a and the nut 20 to be inserted through the bottom portion 50b when placing the implant main body and the nut.

[0044] Fourth, the implant main body is inserted into the hole 50 in the mandible from top to bottom, and the nut is fitted and fastened to a screw portion formed at a lower portion of a bolt body protruding downward from the hole in the mandible.

[0045] Fifth, the gum and the skin under the mandible are sutured. Here, a top portion of the abutment protrudes to the outside of the gum.

[0046] Sixth, a crown is produced and connected to an abutment. In this way, a treatment for placing the bolt-type implant is completed.

INDUSTRIAL APPLICABILITY

[0047] A bolt-type implant may be used in replacing a natural tooth of patients who lost a tooth.
