  • Patent number: 11607294
    Abstract: Disclosed are a fixture for a dental implant and an implant system comprising the same. The implant system of the present inventive concept comprises: a first fixture having a first body part and a first continuous screw part which is formed in a spiral around the outer circumferential surface of the first body part and is formed continuously without a break; and a second fixture having a second body part that is identical to the first body part, and a second continuous screw part which is formed in a spiral around the outer circumferential surface of the second body part and which has an outer diameter that differs from that of the first continuous screw part. The present inventive concept allows implant operations to be carried out in a more straightforward fashion than hitherto since, even if initial fixture placement fails, a subsequent fixture can be placed straight away without any further drilling work.

  • Patent number: 9579167
    Abstract: A dental implant fixture comprises: a body; a continuous thread part including a continuous thread continuously formed in a spiral shape along an outer circumferential direction of the body; a bone damage prevention part formed at one end portion of the body and preventing an alveolar bone existing in an opening area of a hole where the body is implanted from being damaged due to the continuous thread part; and an entrance guide part provided at the other end portion of the body and guiding the body in an initial implantation entrance direction. The entrance guide part comprises; a flat portion of horizontal flat; an inclined portion extending upward from a circumferential surface of the flat portion with an upwardly increasing radius; and a rounded portion connecting the inclined portion and the continuous thread part and having at least one area inwardly rounded toward the centerline of the fixture.

  • Patent number: 8277217
    Abstract: Disclosed is a dental instrument for cutting soft tissue. The dental instrument for cutting soft tissue according to the present invention includes: a main body having an inlet portion for inserting soft tissue to be cut into the main body; a cutter blade arranged in the main body such that at least a part of the cutter blade is exposed outwardly through the inlet portion; and a lid for covering the upper portion of the main body. The cutter blade includes a first cutter blade having a first cut depth, and a second cutter blade arranged in the vicinity of the first cutter blade, and which has a second cut depth shallower than the first cut depth. The dental instrument of the present invention makes it possible to cut the soft tissue in the deep part of a mouth in an easy and simple process, thereby improving the convenience of soft tissue implantation.
