Dental Implants and Restorations: The Ultimate Smile Solution

The invention discloses a dental implant implanted into the missing tooth part of the jawbone to replace the lost teeth. The dental implant according to the present invention includes: a fixture having a threaded connection hole formed at a predetermined depth along its central axis in its interior, the fixture is open at its upper end, and a threaded portion is formed on its outer circumferential surface; a fixation a support at the upper end of the fixing device, and a locking groove is formed in the upper part of its outer circumferential surface; a screw is coupled to the screw coupling hole of the fixing device through the support, and has a sleeve formed on its upper part a tube insertion slot to connect to the locking slit of the abutment; and a locking sleeve that fits within the locking slit of the abutment and the sleeve insertion slot of the screw.

Provided is a dental implant that reliably prevents elution of metal when the dental implant is applied to the oral cavity and reliably prevents misfitting (unevenness) when the dental implant is fixed in place. bite, etc.). The dental implant includes an abutment that includes a titanium member made of titanium or a titanium alloy and having a groove, and a ceramic member made of an oxide-based ceramic and having a protrusion that fits within the groove. In the pre-sintered state, the groove has a first surface shape providing a gap between the groove and the protrusion inserted therein. In the post-sintered state, the recess has a second surface shape corresponding to the surface shape of the protrusion, so that the protrusion and the recess are in close contact and fit.

Placement of dental implants can be facilitated using guidance and/or placement systems. This guide may allow the determination of appropriate locations for dental implants. The patch system places the introducer inside the patient's body.

By creating a computer model that gives the shape of the dental implant drill hole and the dental implant superstructure, giving details of the jawbone structure, information on the shape of the gingival surface and information on the shape of the proposed tooth or denture. The computer model displays images of the bone structure, gingival surface and teeth appropriately referenced to each other, allowing implant drilling locations to be selected taking into account appropriate positioning within the bone and relative to the dental restoration. Similarly, the fabrication of dental implant superstructures for fixed dentures or overdentures can be designed based on knowledge of the actual implant position from images of the gingival surface and reference to the proposed denture.
