## Abstract

The present invention relates to an internal hole filler of an abutment for implant, which includes first polytetrafluoroethylene (first PTFE) and second polytetrafluoroethylene (second PTFE), wherein tensile strength measured after sintering the first PTFE is in a range of 20 MPa or more to less than 28 MPa, and tensile strength measured after sintering the second PTFE is 28 MPa or more, and a method of filling an internal hole of the abutment for implant.

## Claims

### Claim 1

An internal hole filler of an abutment for implant which is inserted into an internal hole of the abutment for implant, the hole filler comprising:
wherein the hole filler includes a first polytetrafluoroethylene (first PTFE) and a second polytetrafluoroethylene (second PTFE),
wherein tensile strength measured after sintering the first PTFE is in a range of 20 MPa or more to less than 28 MPa, and tensile strength measured after sintering the second PTFE is 28 MPa or more.

### Claim 2 (depends on 1)

The internal hole filler of an abutment for implant of claim 1, wherein the first PTFE and the second PTFE are included in a weight ratio of (30:70) to (70:30).

### Claim 3 (depends on 1)

The internal hole filler of an abutment for implant of claim 1, wherein a diameter of the hole filler is smaller than a diameter of the internal hole of the abutment for implant.

### Claim 4 (depends on 1)

The internal hole filler of an abutment for implant of claim 1, wherein the hole filler has a diameter of 0.1 φ to 3 φ.

### Claim 5 (depends on 1)

The internal hole filler of an abutment for implant of claim 1, wherein a length of the hole filler is greater than a length of the internal hole of the abutment for implant.

### Claim 6 (depends on 1)

The internal hole filler of an abutment for implant of claim 1, wherein the hole filler has a length of 5 mm to 80 mm.

### Claim 7

A method of filling an internal hole of an abutment for implant, the method comprising:
disposing an internal hole filler of an abutment for implant, which includes first polytetrafluoroethylene (first PTFE) and second polytetrafluoroethylene (second PTFE), in inside of a hole of the abutment for implant; and
filling the inside of the hole with the hole filler by pressurizing the hole filler using an implant device,
wherein tensile strength measured after sintering the first PTFE is in a range of 20 MPa or more to less than 28 MPa, and tensile strength measured after sintering the second PTFE is 28 MPa or more.

### Claim 8 (depends on 1)

An abutment for implant, the abutment comprising the hole filler of claim 1.

### Claim 9 (depends on 8)

An implant comprising the abutment for implant of claim 8.
