Description

The present invention relates to a dental implant denture structure, and particularly to a lock structure of an all-zirconium integrated dental implant denture without metal pillars.

In general, implants are performed by removing the damaged tooth of the patient or implanting a metal implant at the place where the tooth has fallen directly to make an artificial tooth root, and installing a transfer abutment tooth on the implant. After that, a transfer mold of a material such as silicon is taken, the patient's bite is provided and oral modeling is performed, and the transfer mold is used to obtain the dentition state in the patient's missing tooth area, and then the gypsum model is turned over and the oral model is made. Further, a temporary dental sleeve is made from the oral model, and after fitting, correction or dentures are made.
With reference to FIGS. 6 and 7 for the conventional denture structure, when performing the traditional oral modeling, the transfer abutment tooth is installed on the artificial tooth root, and the denture 50 is made by the oral model. The recess 51 is held in advance relative to the bottom of the 50, and the recess 51 further penetrates the occlusal surface of the denture 50 upward to form an implant perforation 52, and the recess 51 utilizes an adhesive 511. Then, the metal pillar 53 is adhered, and the metal pillar 53 is used to match the artificial tooth root 54 for intraoral implantation, and further, the bolt 55 is used to insert the metal pillar 53 into the implant perforation 52, and the artificial tooth root 54 and the bolt are used. The implant is fixed and finally the implant 56 is used to fill the implant perforation 52 to complete the implant. However, the oral model constructed by the oral modeling is prone to errors, and the physical properties of the metal pillar 53 and the denture 50 are different, the recess 51 of the denture 50 cannot be accurately matched with the metal pillar, and the denture It affects the degree of adhesion between 50 and the metal pillar 53, and it is necessary to further adjust and fix the adhesion over time. On the other hand, traditionally, the denture 50 is used when it is necessary to change the color or add a porcelain material, or after putting it in an oven and slowly heating and lowering the temperature to destroy and disintegrate the adhesive 511 and take out the metal pillar 53. Change the color of the denture 50 again and add the porcelain material. After the work of changing the color and adding the porcelain material, steps such as adhesion and polishing are performed again, and the process is complicated and inefficient, so that it takes time for the patient, the doctor and the dentist. Further, when the denture 50 adheres to and is fixed to the metal pillar 53, the metal pillar 53 which is not the color of the denture is clearly visible between the bottom of the denture 50 and the gum due to the difference in color between the denture 50 and the metal pillar 53. The aesthetics of this denture installation is greatly reduced.
In consideration of this, the present inventor has made a detailed design and a precise evaluation of the above goals based on many years of manufacturing development and design experience of products in this field, and is practical. I got this idea.

The technical problem to be solved by the present invention solves the above-mentioned drawbacks existing in the prior art and provides a lock structure for an all-zirconium integrated dental implant denture.

The lock structure of the dental implant denture includes an artificial tooth root, a denture, an implant screw and a filling, the artificial tooth root is pre-embedded in the gum in the mouth, and the apex of the artificial tooth root is an implant surface and the implant. An implant is formed by the central protrusion of the surface, the implant surface and the implant are exposed on the surface of the tooth stem, and an implant screw hole is provided from the upper surface to the bottom of the implant, and the denture is provided. In the color of the tooth, the denture material made of all zirconium is integrally molded by the 5-axis machine, and the denture is automatically formed through the occlusal surface and bottom surface of the denture by the 5-axis machine. For the inner diameter of the implanting hole, a position-regulating ring portion is installed corresponding to the height of the protrusion of the implanting portion, and a fitting portion is formed below the position-regulating ring portion to fit and cover the implanting portion. In addition, the upper surface of the implanting portion is supported by the position-regulating ring portion, a flat surface is formed on the bottom surface of the denture, and the artificial tooth root is attached in a plane with the implanting surface. It is placed in the implant perforation and locked and fixed to the implant screw hole of the artificial tooth root, and the top end of the implant screw is further formed with a stopper end and pressed downward against the position limiting ring portion, and the filling is The denture structure is completed by injecting into the implant perforation from the occlusal surface of the denture, filling and closing.
Preferably, the denture is a single crown and the implant lock is applied corresponding to one of the artificial tooth roots.
Preferably, the denture is a plurality of crowns or crowns of all jaws and is integrally molded and arranged, and the denture has at least two implantable perforations and corresponds to at least two artificial roots. And lock the planting.
Comparing the effects of the prior art: The dentures of the present invention are all-zirconium integrated molding manufacturing, designed without metal pillars inside the dentures, and the errors and inconveniences caused by the conventional dentures adhering to the metal pillars. Can be processed directly when you want to change the surface color of the denture or add porcelain material, while reducing the cost of using metal pillars, and glued by oven like traditional dentures. Heat the agent to break and disintegrate the adhesive, then separate the metal pillars, change the color, add the porcelain material, then stick the metal stanchions, eliminate the step of polishing the surface, greatly improve the efficiency of denture manufacturing Improves and the dentures have an all-zircon design without metal pillars, while also having an overall aesthetic.
