Technical Field

The utility model relates to the technical field of ceramic false teeth, in particular to a zirconia ceramic repair false tooth.

Background

Tooth restoration is to prepare teeth according to the principle of retention, resistance and protection of pulp-dentin organs on the basis of removing damaged or seriously weakened tooth tissues, and finally, restore the inherent shape and function of the teeth by a certain procedure with specific materials. A common dental prosthesis is generally divided into two types, namely removable denture and fixed denture, wherein the fixed denture cannot be taken by the patient, and the removable denture can be taken by the patient conveniently.

As a dental restorative material, it is first required to have good biocompatibility and not to cause a toxic or side effect to the body. Secondly, the ceramic material as a support material should have enough mechanical strength, and the zirconia ceramic is the first choice for clinical restoration of teeth by virtue of excellent mechanical property, aesthetic property and biocompatibility. The currently used zirconia ceramic prosthetic dentures are generally used as common materials for partial dentures and dental implants.

The zirconia ceramics that currently uses usually restores artificial tooth formula structure as an organic whole, and the installation generally directly plants at the alveolar bone, and artificial tooth probably has wearing and tearing after long-term the use, is difficult for changing the artificial tooth that damages, and the tooth implantation once more brings the misery of patient. And some neotype prosthetic teeth are through carrying out threaded connection with artifical tooth and base station for artifical tooth is easily changed, nevertheless because long-term use is chewed, this kind of threaded connection's structure is easy to be corroded and damaged, leads to the not hard up of artifical tooth, probably leads to the unable guarantee of the automatic security that drops of artifical tooth even.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Unless otherwise specified, in the present invention, if there is an orientation or positional relationship indicated by terms of "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., based on the orientation or positional relationship shown in the drawings, it is only for convenience of describing the present invention and simplifying the description, rather than to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, the terms describing orientation or positional relationship in the present invention are for illustrative purposes only, and should not be construed as limiting the present patent, specific meanings of the above terms can be understood by those of ordinary skill in the art in light of the specific circumstances in conjunction with the accompanying drawings.

As shown in fig. 1, the zirconia ceramic prosthetic denture provided by the present embodiment comprises an implant base 10 and an artificial tooth 30, wherein the implant base 10 can be implanted into an alveolar bone to fix the artificial tooth 30. The artificial tooth 30 is detachably mounted on the implant base 10 to facilitate the detachment, maintenance and replacement of the artificial tooth 30.

In this embodiment, the artificial tooth 30 includes a metal base 31 and a crown 32 disposed on the top of the metal base 31, the metal base 31 and the crown 32 are integrated, the metal base 31 is made of a metal alloy material so as to be connected with the implant base 10, and the crown 32 is made of a zirconia ceramic repairing material so as to improve the wear resistance and take comfort and beauty into consideration.

In this embodiment, in order to facilitate the installation of the artificial tooth 30, the top of the planting base 10 is provided with a connecting base 20 protruding upwards, the bottom of the connecting base 20 is provided with a first external thread 11, the bottom of the metal base 31 is provided with a mounting groove 33, and the metal base 31 is provided with an internal thread 331 matching with the first external thread 11 at the bottom of the mounting groove 33. In specific implementation, the planting base 10 is connected with the artificial tooth 30 through the matching of the internal thread 331 and the first external thread 11, and the connection mode is simple and easy to detach and fix.

In this embodiment, in order to make the implant base 10 stably installed, the bottom of the implant base 10 is provided with a second external thread 12, and the implant base 10 is closely arranged with a plurality of hemispherical protrusions 13 in the grooves of the second external thread 12, so that the surface of the implant base 10 is rough, the stability of the connection between the implant base 10 and the alveolar bone is further improved, and the implant base provides retention, stabilization and support effects for the artificial tooth 30.

In this embodiment, in order to prevent the artificial tooth 30 from automatically falling off after loosening, the connecting seat 20 is provided with two locking grooves 21 and two above the first external thread 11, the locking grooves 21 are oppositely arranged, and the locking grooves 21 are hemispherical and are all located on the side wall of the connecting seat 20. The inside of mounting groove 33 still is equipped with locking subassembly 40, just locking subassembly 40 is located the top of internal thread 331, locking subassembly 40 includes the retaining member and is used for promoting the retaining member is half embedded in the elastomeric element in mounting groove 33, the tip of retaining member is globular. In specific implementation, the locking member is pushed by the elastic member so that the front end of the locking member is correspondingly inserted into the locking groove 21. Specifically, two sets of the locking grooves 21 are provided, and the two sets of the locking grooves 21 are oppositely arranged on the side wall of the connecting seat 20. The elastic component is a magnetic spring 41 horizontally arranged in the mounting groove 33, one end of the magnetic spring 41 close to the side wall of the mounting groove 33 is fixedly connected with the metal base 31, the other end of the magnetic spring 41 is fixedly connected with the locking piece, the locking piece is a magnetic metal ball 42, in specific implementation, the magnetic metal ball 42 is pushed by the magnetic spring 41 to be embedded into the locking groove 21, when the magnetic metal ball 42 is embedded into the locking groove 21, two ends of the magnetic metal ball 42 protrude out of the connecting seat 20, and therefore the artificial tooth 30 cannot be pulled out of the planting base 10 when the artificial tooth 30 is loosely connected with the planting base 10. When the artificial tooth 30 needs to be taken out, the magnetic spring 41 and the magnetic metal ball 42 are attracted from both ends by using a device capable of generating magnetic force, so that the magnetic spring 41 compresses and drives the magnetic metal ball 42 to move towards both sides and separate from the locking groove 21, and at the moment, the artificial tooth 30 can be rotated to enable the artificial tooth 30 to fall off from the implantation base station.
