DENTAL-MEMBRANE FIXING MEMBER AND COVER MEMBER

摘要

The present invention relates to a dental-membrane fixing member, and more particularly to a dental-membrane fixing member for fixing a dental membrane that induces growth of alveolar bone by covering a bone graft material. The dental-membrane fixing member comprises: a fixture implanted in the alveolar bone; an abutment which is detachably connected to the fixture and comprises a lower threaded part having a male thread on the outer circumferential surface thereof, a body part positioned above the lower threaded part, and an upper threaded part which protrudes from the center of the top end of the body part and has a male thread on the outer circumferential surface thereof; and a cover member which is provided with a female threaded recess having a shape corresponding to the upper threaded part and is detachably connected to the abutment so as to fix the dental membrane; wherein the top end of the abutment body part is provided with a first seat surface that expands with increasing height toward the center of the top end thereof from the edge so as to contact the lower surface of the dental membrane, and the bottom end of the cover member is provided with a second seat surface having a shape that matches the first seat surface and contacts the upper surface of the dental membrane.
