The technical field is as follows:
the invention belongs to the technical field of dental medical equipment, and particularly relates to a dental implant abutment.
The background art comprises the following steps:
with the continuous development of the oral implantation technology, the oral implantation technology is gradually mature and stable. The implant denture is formed by implanting a biocompatible titanium metal implant, forming osseointegration in the alveolar bone and then installing a crown on the implant denture through the connection of an implant abutment. The implant abutment does not have a physiological structure corresponding to teeth, the implant abutment is not firmly combined with gingiva, and the gingiva around the implant abutment cannot well share the force applied by the implant abutment during chewing, so that the implant abutment is easily bent, and the effect of the implant tooth is influenced.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
The invention content is as follows:
the invention aims to provide a dental implant abutment, so as to overcome the defects in the prior art.
In order to achieve the above object, the present invention provides an abutment for dental implantation, comprising a table body, a transition surface and a base, wherein the base is connected with the implant, the transition surface is arranged between the base and the table body, the periphery of the transition surface is wrapped with gingival muscle fibers, the table body is fitted with the transition surface by fitting a bicubic B-spline curve with a tooth chewing process, and the parameter form of the curve is as follows:
B(t)＝P 0 (1-t) 3 +3P 1 t(1-t) 2 +3P 2 t 2 (1-t)+P 3 t 3 ，t∈[0,1]
wherein, P 0 At a point at the top of the table body, P 3 A point at the bottom of the table body, P 1 For chewing by teeth P 0 Point in the direction of motion, P 2 For chewing by teeth P 3 Point in the direction of motion, curve starting from P 0 Trend P 1 And from P 2 Direction of (1) is finally P 3 。
Preferably, in the technical scheme, the transition surface is designed to be a double-spiral surface, so that the transition surface is combined with the gingival muscle fibers more firmly, and the bending resistance of the abutment is improved.
Preferably, in the technical scheme, the base platform is an inclined base platform, and a certain angle is formed between the platform body and the substrate.
Preferably, in the technical scheme, the base platform is made of TC4 material, and when the angle between the platform body and the base is 30 degrees, the flexural strength of the base platform is more than 540N.
Preferably, in the technical scheme, the base station is a straight base station, and a stress line is arranged between the station body and the base station.
Compared with the prior art, the invention has the following beneficial effects:
the dental implant abutment fits the transition surface by fitting the tooth chewing process, the design of the abutment and the stress angle can be optimized, the transition surface of the abutment is designed by adopting the double spiral surfaces, the optimal package of gum muscle fibers can be obtained, and the bending resistance of the abutment is improved in an auxiliary manner.
