Description

Personalized base station

Technical Field

The utility model relates to a dental tool technical field, in particular to individualized base station.

Background

In recent years, dental implants have become an increasing repair option for patients with missing teeth. The abutment is an important prosthetic part for connecting the implant and the superstructure, and is important for the function and aesthetic effect of the implanted denture. Although the existing finished product abutment has various types, the form is single, the specification is fixed, the selection aiming at the oral cavity of different patients is quite strict, and the individualized function and aesthetic requirements of the patients are difficult to be considered. On one hand, the prosthesis manufactured by the finished abutment can not achieve ideal functions and beautiful shapes, for example, the common neck is small, and the prosthesis is easy to appear in a black triangular area and the like; on the other hand, the height of the gum of each patient is inconsistent, even if the finished abutment can grind the gum penetrating part, the ideal gum height can not be achieved, the biggest problem is that the adhesive can not be removed after bonding, and the finished abutment can not completely meet the clinical requirement in some cases. Therefore, the existing product abutment has certain repair function and aesthetic defects of the gum area, and needs further improvement.

In addition, the drop height of the lingual endpoint, the buccal endpoint, the mesial endpoint and the distal endpoint is designed to make the contour of the top of the transgingival area similar to the anatomical morphology at the natural enamel cementum junction. On one hand, the design can realize perfect shaping of the sleeve opening of the implant, thereby achieving ideal anatomical form repair and being beneficial to self-cleaning and cleaning of the edge of the prosthesis; on the other hand, the reasonable transmission and distribution of the occlusion stress are facilitated.

Further, the projected area of the top of the gum penetrating area is larger than the projected area of the bottom, the side wall of the gum penetrating area is a curved surface with taper, and the taper is 8-9 degrees. The taper curved surface can reduce the processing difficulty of the personalized base station and avoid the interference of a machine tool cutter to other areas during machining.

Further, the body also comprises an interface area, the interface area is connected with the bottom of the gum penetrating area, and the interface area is provided with an interface matched with a peripheral dental implant. The interface area is used for being connected with a peripheral dental implant, so the types of the interface include hexagonal connection, cross locking connection, quincuncial connection, four-corner connection, triangular connection, Morse taper connection and the like.

The land area is a cylindrical or wedge-shaped member. If the personalized abutment is arranged in the posterior tooth area, the connecting area is cylindrical with a certain drawing angle, and the drawing angle is 0-35 degrees; if the dental implant is arranged in the anterior tooth area, the dental implant is wedge-shaped. When the implantation direction of the implant and the relation between the implant and adjacent tissues do not completely meet the repair requirement, the axial deflection angle of the designed connecting platform area can be changed to compensate.

Further, the length of the connecting table area is 4-8 mm.

Furthermore, the surface of the connecting table area is provided with at least one arc-shaped microgroove. The existence of the arc-shaped microgrooves can increase the surface area of the connecting table area, so that the dental crown and the abutment are connected through the adhesive and then are not easy to fall off.

Further, individualized base station still includes the screw channel that runs through the body, the screw channel sets up along the axis of wearing the gum region. The upper end wall thickness of the screw channel is more than or equal to 0.6 mm.

The utility model has the advantages of it is following: the personalized abutment can control the outline curve of the gum penetrating area through the hyperbolic paraboloid, so that the personalized design of the form of the gum edge is met, the natural tooth form can be simulated to a certain degree, no dead angle can be formed by repairing and connecting the personalized abutment with the upper part, and the personalized abutment is attractive and healthy. After simulation analysis, the personalized abutment has good static performance.
