High-stability false tooth

Technical Field

The utility model relates to an artificial tooth field especially relates to a high stability artificial tooth.

Background

The denture is what is commonly called a "denture". Just like "leg prosthesis" and "prosthetic limb" are referred to as "prosthetic limb", a "denture" means that the human being is "obligated" to the utmost. The medical science is a general term for restorations made after partial or all teeth of the upper and lower jaws are lost. The artificial tooth is divided into removable type and fixed type. Fixed dentures (commonly known as "fixed dentures") are not worn by the patient himself, while removable dentures (commonly known as "removable dentures") are worn by the patient easily.

The quality of the denture depends not only on its own material, but also largely on whether it can be stably fixed in the oral cavity of the patient without loosening for a long time.

The utility model discloses a chinese patent application number 202021831339.3's utility model discloses a removable denture of high stability relates to artificial tooth technical field, including the artificial tooth base, a plurality of prosthetic tooth grooves have been seted up on the artificial tooth base, the tank bottom of prosthetic tooth groove is equipped with the erection column, install the artificial tooth body on the erection column, the mounting groove with erection column matched with is seted up to the bottom of artificial tooth body, the shaping has a plurality ofly and chimb matched with recess on the perisporium of erection column. This novel through set up a plurality of chimbs on the perisporium of erection column to set up on the cell wall of mounting groove with chimb matched with recess, utilize cooperation between chimb and the recess, improved the stability of artificial tooth body installation, improved the holistic life of removable denture, above-mentioned utility model provides a technical scheme has provided better stability on the horizontal direction, it cooperatees through chimb and recess and realizes, but does not improve the innovation to it of vertical direction, if the patient chews viscidity food, then can get up the artificial tooth adhesion.

SUMMERY OF THE UTILITY MODEL

Therefore, in view of the above problems, the present invention provides a high-stability artificial tooth, which solves the technical problem that the existing artificial tooth is easily adhered during the chewing process of the artificial tooth facing viscous food.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the high-stability false tooth comprises a false tooth body, wherein the false tooth body is fixedly matched with an alveolar bone of a human body according to the lower part to the upper part and comprises an implant body, a connecting base station and a dental crown, the implant body is in an inverted circular table shape and comprises a threaded part and a connecting table top connected with the connecting base station, the threaded part is screwed with the alveolar bone of the human body, a first connecting groove is formed in the connecting table top, a first connecting bulge is arranged on the lower surface of the connecting base station and movably connected with the first connecting groove, a cylindrical boss is arranged on the upper surface of the connecting base station, an elastic bulge is arranged on the outer circumferential surface of the boss, a cylindrical groove matched with the boss is formed in the lower surface of the dental crown, an annular clamping part is arranged on the inner circumferential surface of the groove, and the elastic bulge is clamped in the annular clamping part.

Further, a silica gel layer is arranged on the outer circumferential surface of the connecting base station.

Further, the thickness of the silica gel layer is 0.8-1mm, and the silica gel layer is used for contacting with gingival tissues.

Further, the first coupling projection and the first coupling groove are screw-coupled.

Furthermore, the dental crown is an all-ceramic dental crown, and the connection abutment is a pure titanium connection abutment or an all-ceramic connection abutment.

By adopting the technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses in, the planting body directly closes with the alveolar bone spiral shell, and its principle is that the planting body (artifical root of a tooth) is planted deeply in the alveolar bone, has functional stimulation to the alveolar bone, can protect alveolar bone structure, avoids its atrophy, and simultaneously planting body and alveolar bone are rigid material, and the two rigid connection is more firm, and planting tooth can not take place to drop and cause the danger of plugging up trachea or esophagus like ordinary movable denture when eating or speaking simultaneously, compares with traditional movable denture, and planting tooth possesses more permanent life and the quality is more reliable; the implant is movably connected with the connecting base station, so that the connecting base station can be detached to maintain and repair the dental crown on the connecting base station; the elastic bulge is arranged on the outer circumferential surface of the boss, the cylindrical groove matched with the boss is arranged on the lower surface of the dental crown, the annular clamping part is arranged on the inner circumferential surface of the groove, and the elastic bulge is clamped in the annular clamping part, so that the dental crown is matched with the connecting base station more stably, and the dental crown cannot be stuck up due to the fact that food with larger viscosity is eaten.

2. The outer circumferential surface of the connecting base station is provided with a silica gel layer, the thickness of the silica gel layer is kept at 0.8-1mm, the silica gel layer is used for being in contact connection with gum tissues of a human body, on one hand, the silica gel layer and the gum tissues are both flexible, and the gap between the silica gel layer and the gum tissues can be filled by flexible connection between the silica gel layer and the gum tissues, so that food residues are prevented from falling into the gap.

3. First connection arch and first connection recess screw-thread fit have promoted the compactness of connecting between the two, avoid producing not hard up.

4. The dental corona is an all-ceramic dental corona, the connection base station is a pure titanium connection base station or an all-ceramic connection base station, on one hand, the material can provide stronger hardness, and on the other hand, the allergy of the oral cavity of a human body to other materials can be avoided.
