Description
Technical Field
The utility model relates to a kind of implant technical field, specifically a kind of dental implant with retention stake.
Background
The implant is to support the fixed upper dental prosthesis based on the lower structure implanted in the bone tissue, and includes two parts, one lower implant and one upper dental prosthesis, the implant is made of artificial material similar to tooth root, and the implant is implanted into the tissue via operation to obtain firm fixed support of the bone tissue, and the upper dental prosthesis is connected via special device and mode.
The implant can obtain the repairing effect which is very similar to the function, the structure and the beautiful effect of the natural tooth, and becomes the first-choice repairing mode of more and more patients with tooth deficiency. The dental implant in the prior art has a structure shown in fig. 1, and comprises an implant 2, a connecting stud 3, an abutment 4 and an artificial dental crown 5 which are sequentially matched and installed from bottom to top, wherein the implant 2 positioned at a bottom base supporting position is screwed into an internal thread blind hole formed in an alveolar ridge 1 of a dental patient in a threaded manner, the abutment 4 is made of a medical titanium alloy material, and the artificial dental crown 5 is fixed on the abutment 4 by using a medical cement.
Although the above-described conventional techniques can achieve a simple dental implantation, the artificial crown 5 is fixed to the abutment 4 using a medical cement. First, after the dental implant is used for a long time, the situations of abutment screw loosening, food impaction, artificial dental crown breakage and the like occur, the artificial dental crown needs to be removed for maintenance, the artificial dental crown is very difficult to remove due to bonding, and the implant can be damaged in the process. The artificial dental crown needs to be made again. Screw retention does not present this problem and only the screw is loosened to deliver the damaged crown to the technician. After the repair is finished, the artificial limb is returned to the oral cavity for use, so that the cost is saved, and convenience is brought to patients; secondly, the long-time chewing pressure can cause the cohesive force to be reduced, and the failure of the cohesive force can cause the artificial dental crown 5 to fall off from the abutment 4, so that the stability is deteriorated, and the normal use of the dental implant is influenced.
In addition, many advantages are provided for the currently popular multi-dental implant combined restoration, but for the convenience of later maintenance, a screw retaining connection mode is mostly adopted, the artificial dental crown 5 inevitably has processing errors in the processes of mold taking, mold filling, manufacturing, processing and the like, the implant 2 with unmatched errors and the artificial dental crown 5 are rigidly fixed together through the screw retaining rigid connection, and thus some stress exists between the implant 2 and the artificial dental crown 5, so that the retaining screw of the dental implant is required to bear chewing pressure in daily chewing, the stress of the close fit between the implant 2 and the artificial dental crown 5 is also required to be resisted, and the situations of screw fracture, abutment 4 damage, artificial dental crown 5 fracture, even implant 2 looseness and the like can occur for a long time.
