Dental abutment construction member and production method

A dental abutment construction member having a tubular shape, comprising:

• an upper surface;
• a lower surface;
• an outer peripheral surface;
• and
• an inner peripheral surface,
• wherein each of the upper surface and the lower surface has an annular shape,
• wherein the outer peripheral surface connects an outer edge of the annular shape of the upper surface and an outer edge of the annular shape of the lower surface,
• wherein the inner peripheral surface connects an inner edge of the annular shape of the upper surface and an inner edge of the annular shape of the lower surface,
• wherein the inner edge of the annular shape of the upper surface has an elliptical shape,
• wherein the inner edge of the annular shape of the lower surface has an elliptical shape,
• wherein an axis in a longer direction of the elliptical shape which is the inner edge of the annular shape of the upper surface and an axis in a longer direction of the elliptical shape which is the inner edge of the annular shape of the lower surface are in the same plane,
• wherein a length in the longer direction of the elliptical shape which is the inner edge of the annular shape of the upper surface is in a range including both ends of a range from 4.0 mm to 9 mm, and a length in a short direction of the elliptical shape which is the inner edge of the annular shape of the upper surface is in a range including both ends of a range from 4.0 mm to 9 mm,
• wherein a length in the longer direction of the elliptical shape which is the inner edge of the annular shape of the lower surface is in a range including both ends of a range from 4.0 mm to 9 mm, and a length in the short direction of the elliptical shape which is the inner edge of the annular shape of the lower surface is in a range including both ends of a range from 4.0 mm to 9 mm,
• wherein a width in a horizontal plane of the outer peripheral surface is in a range including both ends of a range from 5.0 mm to 10 mm,
• wherein a thickness of a wall formed by the outer peripheral surface and the inner peripheral surface is at least 0.5 mm,
• wherein a height of the dental abutment construction member is in a range including both ends of a range from 2 mm to 10 mm,
• wherein the dental abutment construction member is a member that reinforces the cervical portion, and
• wherein the dental abutment construction member is a member that is used to be embedded in a composite resin such that the dental abutment construction member is not in contact with a tooth substance inside an abutment construction cavity.
