Dental implantation and restoration
The present invention discloses a dental implant for replacing lost teeth in the jawbone with a missing tooth site. The dental implant according to the present invention comprises: a fixator having a threaded connection hole formed at a predetermined depth along its central axis inside, the fixator opening at its upper end, and a threaded portion formed on its outer circumferential surface; A support fixed at the upper end of the fixed device and forming a locking groove on the upper part of its outer circumferential surface; A screw, which is connected to the screw connection hole of the fixing device through the support, and has a sleeve insertion groove formed on its upper part to connect to the locking slit of the support; And a locking sleeve, which is assembled in the locking slit of the base and the sleeve insertion slot of the screw.
Provided is a dental implant that can reliably prevent metal elution when applied to the oral cavity and can reliably prevent misalignment (uneven bite, etc.) when the dental implant is fixed in place. The dental implant comprises a abutment, which includes a titanium component made of titanium or titanium alloy with grooves, and a ceramic component composed of oxide based ceramics with protrusions fitted into the grooves. 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 sintering state, the concave portion has a second surface shape corresponding to the surface shape of the protrusion, allowing the protrusion to closely contact and fit with the concave portion.
The use of guidance and/or placement systems can facilitate the placement of dental implants. This guide may allow for determining the appropriate location for dental implants. The patch system can place the guide device inside the patient's body.
By creating a computer model, the shape of the dental implant drill hole and the upper structure of the dental implant are provided, along with details of the jawbone structure, gingival surface shape information, and proposed tooth or denture shape information. The computer model displays bone structures, gingival surfaces, and tooth images that are appropriately referenced to each other, allowing for consideration of appropriate positioning within the bone and relative to the dental restoration to select implant drilling positions. Similarly, the manufacturing of the upper structure of dental implants used for fixing dentures or dentures can be designed based on knowledge of the actual implant position with reference to gingival surface images and the proposed dentures.
