Disclosed is a palatal implant for an overdenture. The palatal implant for an overdenture according to one embodiment of the present invention comprises: an implant insertion body which is inserted in a predetermined insertion position of the palatal by means of operation of a screw portion formed on the outer surface of an overdenture; and a head which has a cuff connected to the upper portion of the implant insertion body, and which is externally exposed from the insertion position.

The present invention relates to a dental implant, and more particularly, to a dental implant in which a fixture and an abutment are together by a separate screw post so as to prevent the breakage of an implant screw tightening part and uniformly transmit forces over the entirety of a contact surface, to thereby prevent stresses from being partially concentrated, and in which the screw-tightening direction between the fixture and the abutment is variable so as to improve the coupling force between the fixture and the abutment and fundamentally prevent a screw from becoming loosened. The dental implant of the present invention comprises said fixture and abutment, the abutment including a lower abutment to be fitted onto the fixture, and an upper abutment connected to an upper portion of the lower abutment, the lower abutment and the upper abutment being separate from each other. The upper abutment and the fixture are coupled and fixed by the screw post.

Provided are a dental implant abutment and a method of manufacturing the same, and more particularly, a dental implant abutment which forms an outer appearance of an artificial tooth, supports a porcelain prosthesis that is formed of a porcelain, and couples to and fixedly combines with a fixture. The dental implant abutment includes: a first part having a coupling structure that corresponds to an inner structure of the fixture, so that the first part couples to the fixture; a second part that extends upward from the first part and contacts gums; and a third part extending upward from the second part, having an outer circumferential surface which includes a side surface and a top surface, with a porcelain prosthesis attached to the outer circumferential surface, and including a shape in which a concave part, inwardly recessed, is formed on the side and a horizontal cross-sectional area increases in an upward direction from the concave part.
摘要:
A dental implant system for securing a dental prosthesis within a prepared site of a jawbone in a subject having an implant configured for insertion within the prepared site of the jawbone and an abutment configured for secure attachment to the implant. The implant can have a shoulder portion having a plurality of circumferential rings and a body portion that can be threaded. The implant can have an internal cavity that is configured or otherwise adapted to receive at least a portion of the abutment.

A temporary dental cement composition temporarily affixes a dental prosthesis or appliance to a tooth or other dental substrate. The dental cement includes a mixture of: (i) an ion leaching agent; (ii) polycarboxylic acid; (iii) sugar; and (iv) water. The sugar is added in a sufficient amount that the ion leaching agent and polycarboxylic acid form a hardenable adhesive having an adhesive matrix which forms a relatively weak, temporary bond, as opposed to a permanent bond. The temporary cement composition is compatible with subsequent deposition of typical bonding materials, such as resin luting agents as well as non-resin permanent cements.

Disclosed is an integral-type implant including an intraosseous implant part, a gum penetration part, and a prosthetic appliance attachment part integrated with each other to solve an aesthetic problem which is not solved in a conventional integral-type implant so that an aesthetic customized prosthetic appliance is attached and then the final prosthetic appliance is attached to the aesthetic customized prosthetic appliance. The integral-type implant includes the intraosseous implant part is provided integrally with a lower portion of the integral-type implant and buried in an alveolar bone, the gum penetration part is provided integrally with an upper portion of the intraosseous implant part and buried in a gum to cover the alveolar bone, the prosthetic appliance attachment part provided integrally with an upper portion of the gum penetration part to attach a final prosthetic appliance , which is molded in a dental technical laboratory or formed in CAD/CAM, thereto; and a prosthetic appliance attachment central hole having a through hole extending from an upper end surface of the prosthetic appliance attachment part toward the intraosseous implant part such that the final prosthetic appliance is attached to an inner surface of the through hole.
