Problems solved by technology

The disadvantage of this existing abutment is that: since only one side is provided with a slope, when the denture is fixed on the abutment, the force on the denture is uneven and affects the stability of the fixation.

Embodiment Construction

[0018] In order to further understand the dental implant abutment, the content of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] It is composed of a crown connection section 1, a middle gingival section and an implant insertion section. The crown connection section, the middle gingival section and the implant insertion section form a whole from top to bottom; the inside of the abutment has a stepped hole, and the The stepped hole is a conical surface.

[0020] The crown connection section 1 is a cone with a taper of 6° downwards, and vertical cutting grooves 2 are arranged on its two sides, and the two cutting grooves 2 are symmetrically distributed on the two sides, which can position teeth Crown, but also play an anti-rotation role.

[0021] The middle gingival section is composed of a conical transition section 3 and a conical mating section 4, and the surface of the conical transition section 3 is coated with ...

Abstract

The invention relates to a dental implant abutment, in particular relates to an abutment internally connected with an implant, and belongs to the fields of oral implant and repair. The connecting abutment consists of a crown connecting section, a middle trans-gingival section and an implant insertion section sequentially from top to bottom. The upper crown connecting section of the connecting abutment is a downward enlarged cone of which the taper is 6 degrees. A vertical cutting groove is formed in each of two lateral surfaces of the upper crown connecting section of the abutment, and the two cutting grooves are symmetrically distributed on the two lateral surfaces. The abutment can be used for positioning a crown, and plays a role in resisting rotation. A conical transition section is arranged between the abutment and a connector, and a silver-carrying TiO2 antibacterial coating is coated on the surface. After the abutment is inserted into the inner cavity of the implant, seal fit of conical surfaces, anti-rotating directional fit of eight-angular prism surfaces and pilot fit of cylindrical surfaces can be realized. The invention aims to provide the abutment internally connected with the implant, and the abutment is matched with the implant precisely and stably and has excellent anti-rotating performance.

Description

technical field [0001] The invention relates to a dental implant abutment, in particular to an abutment connected with an implant, which belongs to the field of oral implantation and restoration. Background technique [0002] Dental implant is a new restoration technology for the treatment of missing teeth. Because it can better restore the chewing function, its appearance is realistic and beautiful, just like natural teeth, so more and more patients choose dental implants for dentition defects or Restoration of missing teeth. The most common is the split implant system, which consists of an implant, an abutment that matches the implant, and is used to load and fix the crown, and a central screw. [0003] The existing dental implant retention abutment comprises an upper crown connection section, a lower implant connection section, and a transition section in the middle. One side surface of the crown connection section of the retained abutment has an inwardly inclined slope...
