Description

Full-zirconium integrated dental implant denture locking structure

Technical Field

The present invention relates to a dental implant denture structure, and more particularly to a full zirconium integrated dental implant denture fastening structure without a metal pillar.

Background

At present, the tooth implantation is implemented by removing a damaged tooth of a patient or directly implanting a metal implant as an artificial tooth root at a tooth falling part, arranging a transfer printing abutment tooth on the implant, then taking a transfer printing mold made of materials such as silica gel and the like, providing occlusion for the patient to carry out intraoral modeling, obtaining the dentition state of the tooth lacking area of the patient on the transfer printing mold, then carrying out plaster mold turning to produce an oral cavity model, producing a temporary tooth socket on the oral cavity model, and modifying or producing false teeth through trial wearing and test conditions.

Referring to fig. 6 and 7, in a dental prosthesis structure in the prior art, in a conventional intraoral modeling, a transfer abutment is disposed on an artificial tooth root, so that a concave portion 51 is reserved on a bottom of the artificial tooth 50 when the dental prosthesis 50 is manufactured by the dental model, the concave portion 51 further penetrates through an occlusal surface of the artificial tooth 50 to form an implant through hole 52, the concave portion 51 is formed by adhering a metal pillar 53 to an adhesive 511, fitting the metal pillar 53 to an intraoral implanted artificial tooth root 54, placing the implant through hole 52 to the artificial tooth root 54 through a bolt 55, and fixing the implant through hole 52 by a screw lock, and finally filling the implant through hole 52 with a filler 56 to complete the implant; however, the oral cavity model formed by the above-mentioned intraoral modeling is prone to error, and due to the difference in physical properties between the metal post 53 and the denture 50, the concave portion 51 of the denture 50 cannot be accurately fitted to the metal post 53, and the adhesion and the fitting between the denture 50 and the metal post 53 are affected, and further time-consuming adjustment and adhesive fixation are required, while the conventional denture 50 is required to be changed in color or porcelain by gradually heating and cooling in an oven to destroy the disintegrating adhesive 511, and the metal post 53 is taken out and then the denture 50 is changed in color and porcelain are added, and after the above-mentioned color change and porcelain addition, the steps of adhesion and polishing are repeated, which is complicated and inefficient, and the patient and the doctor are time-consuming and laborious with the dental technician; in addition, when the denture 50 is fixed to the metal post 53 by adhesion, the metal post 53 having a non-dental luster can be clearly seen between the bottom of the denture 50 and the gum due to the difference in color between the denture 50 and the metal post 53, which significantly reduces the aesthetic appearance of the denture.
