Detailed Description
As shown in fig. 1-2, the dental implant supporting device comprises a supporting main body and a connecting body 3, wherein the supporting main body comprises a dental crown supporting part 1 and a conical abutment 2, the dental crown supporting part 1 is provided with a concave groove 12 which penetrates from the middle part to one side, the cross section of the concave groove 12 is U-shaped, the top of the dental crown supporting part 1 is provided with an arc-shaped edge, and the top of the dental crown supporting part 1 is downwards sunken to form an occlusal surface; the connector 3 and the support main body are integrally formed and used for being connected with an implant.
By adopting the technical scheme, before the dental implant supporting device is used, an impression is taken after the implant and the alveolar bone form osseointegration. At the moment, the prosthesis crown is manufactured on the dental crown supporting part 1 through zirconium oxide, and because the dental crown supporting part 1 is provided with the concave groove 12 and the top of the supporting part is an occlusal surface formed by inclusion of arc edges, compared with the prior art, the existing supporting device is only a small and single thin cylinder above, the support for the prosthesis crown is weak, and the overall shape of the dental crown supporting part 1 is similar to that of a natural tooth, so that the prosthesis crown can be effectively supported, and the risk of ceramic collapse is reduced; the arrangement of the concave groove 12 also provides positioning and supporting functions for the manufacturing process of the prosthesis crown, compared with the traditional base station, the base station is circular, due to the existence of the concave groove 12, on one hand, the prosthesis crown enters the concave groove 12 to provide stability like a bolt, on the other hand, the base station accords with the structure of a natural tooth, one surface of the natural tooth is attached to a cheek, and the other surface of the natural tooth is attached to a tongue, the side of the concave groove 12 which penetrates through is used as a lingual surface, and the side which does not penetrate through is used as a buccal surface, so that the base station is convenient for medical staff to operate and position.
Meanwhile, as the connecting body 3 and the supporting main body are integrally formed, after the prosthesis crown is manufactured, the prosthesis crown is installed on the implant through the connecting body 3, and the situation that the prosthesis crown is directly manufactured on a traditional supporting device so that the adhesive is difficult to clean and periodontitis of a patient is caused can be avoided.
Preferably, the tapered abutment 2 includes a forward tapered section 21 and an inverse tapered section 22, the forward tapered section 21 is connected to the connection body 3, and the inverse tapered section 22 is connected to the crown support part 1. The forward conical shape of the forward conical section 21 conforms to the internal connection shape of the natural tooth gum, so that the installation is convenient; the inverted cone-shaped section 22 is convenient for making and forming the prosthesis crown after being connected with the dental crown supporting part 1, and the made and formed prosthesis crown is smoothly connected with the forward cone-shaped section 21 due to the shape of the inverted cone, so that the existing round supporting part is not in accordance with the anatomical form of the natural tooth and the occurrence of the glue overflow situation can be avoided.
Preferably, a first through hole is formed in the support body, and a second through hole is formed in the connecting body. The first through hole in the support main body is convenient for the screw to pass, and the second through hole 31 that opens in the connecting body 3 is convenient for the screw to be connected with the planting body realization.
