Abstract
The utility model relates to a false tooth retention precision attachment which comprises a fixed dental crown, a movable artificial tooth, a negative part and a positive part, wherein the positive part/negative part is connected with a connecting rod; the connecting rod is matched with the through hole of the fixed dental crown; the negative part/positive part is matched with a prefabricated hole positioned on the movable artificial tooth; and the negative part and the positive part are connected through a clamping mechanism. The false tooth retention precision attachment disclosed by the utility model has the advantages that only the through hole matched with the precision attachment is arranged on the fixed dental crown, the through hole can be a straight hole and can also be a threaded hole, the precision attachment and the fixed dental crown are connected together through screw threads or a positioning clamp spring or an adhesion mode and the connecting mode has the advantage of convenience for replacement without casting, grinding and polishing links, thereby ensuring the accuracy of the precision attachment and achieving better usage effect.
Description
Technical field
This utility model belongs to tooth prosthetic device technical field, is specifically related to a kind of denture retention precision attachment.
Background technology
Traditional maintenance precision attachment is arranged on fixedly on the corona, need and fixedly corona cast together, if precision attachment damages, can not change separately, need change together with fixing corona, not only increase patient's medical expense, and increased workload and time.Because traditional precision attachment need be cast together with fixing corona, also want sanding and polishing after the casting in addition, may cause precision attachment to be out of shape like this.
Therefore, designing a kind of denture retention precision attachment simple in structure, that can conveniently install and change is a technical problem of needing solution badly.
The utility model content
The purpose of this utility model is a kind of simple in structure, the denture retention precision attachment that can conveniently install and change of design.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of denture retention precision attachment, comprise fixedly corona, detachable dental prostheses, female part and male part, be connected with connecting rod on described male part/female part, described connecting rod and fixedly the through hole of corona be complementary, pre-manufactured hole on described female part/male part and the detachable dental prostheses is complementary, and described female part is connected by snap fastener with male part.
Preferably, the male part of described snap fastener is the cylindrical cone of taper ratio 1:6 to 1:20, and described female part is the tapered sleeve that is complementary with cylindrical cone.
Preferably, the male part of described snap fastener is that a upper end has two semicircle spring leafs, and 1/3 expands on the described spring leaf, and described female part is a cutting ferrule that is complementary with semicircle spring leaf.
Preferably, the male part of described snap fastener is that a lower end has two semicircle spring leafs, and 1/3 expands under the spring leaf, and described female part is to descend the snap ring of 1/3 place's constriction and semicircle spring leaf coupling in one.
Preferably, the male part of described snap fastener be a bottom taper ratio 1:6 to the cylindrical cone of 1:20, female part is a tapered sleeve with cylindrical cone coupling.
Preferably, the male part of described snap fastener is that a top is spherosome, and the bottom is a cylinder that mates with through hole, and female part is a resilient sleeve of mating with male part.
The beneficial effects of the utility model:
This utility model precision attachment only need be at the through hole that fixedly corona arranges and precision attachment mates, can be that straight hole also can be screwed hole, accurate adnexa and fixing corona are to link together by screw thread or the form of locating jump ring or bonding, and this connected mode advantage is:
1, is convenient for changing, when accurate adnexa damages, only needs accurate accessory replacing is got final product, needn't change fixedly corona, alleviate patient medical expense and doctor skilled worker's work load.
2, reduce high temperature and cause the precision attachment distortion, because traditional precision attachment need be cast together with fixing corona, also want sanding and polishing after the casting, may cause accurate adnexa to be out of shape like this.This utility model precision attachment is not cast the sanding and polishing link, has guaranteed the precision attachment precision, has better result of use.
