Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a windowed impression connector for repairing a dentures without dental implants.
Background
Restoring the aesthetic and chewing function of a toothless jaw patient is a clinical problem in dentistry. For the toothless patients, the traditional complete denture restoration mode is generally adopted in clinic, but is difficult to accept and adapt to the toothless patients due to poor retention and stability. In recent years, with rapid development of oral implant technology, a dentognathic implant restoration technology has been accepted by more and more dentognathic patients, including a dentognathic overlay implant denture restoration technology and a dentognathic fixed implant denture restoration technology. The dental implant restoration is good in retention, attractive and comfortable, especially the full-mouth implant fixed denture restoration is free from the defect that implant covered denture attachment parts are easy to wear, is closer to natural teeth, can restore the chewing function of a patient to the greatest extent, and becomes a reliable toothless jaw reconstruction scheme. However, the fixed dentures for toothless implants are more demanding on the patient's condition and clinical practice and experience of the doctor than the covered dentures for toothless implants. Clinically, the fixed false teeth supported by the dental implant can be divided into a single crown, a connecting crown and a fixed bridge according to the type of the implant prosthesis, and the connecting crown or the fixed bridge can be an integral body or divided into a plurality of sections. According to the earliest design of the Branmark, for mandibles with dentition missing, the most ideal situation is to implant 6 implants between the chin holes on both sides, which provide support for the repair of the fixed denture. Some studies showed that: the fixation repair in the same manner supported by 4 to 5 implants has the same retention as the fixation repair supported by 6 implants. The number of implants required for implantation fixation repair has heretofore been at least 4. The most representative is the "All on four" repair design. The All-on-four implant denture restoration has more advantages compared with the traditional toothless jaw restoration mode, and can reduce the complication occurrence risk while shortening the treatment time and lowering the cost.
Regardless of the form of dentures without dental implants, it is clinically necessary to make a horizontal impression of the implant after the implant is implanted and prior to the preparation of the prosthetic denture, and it is necessary to use a fenestration tray impression technique or a closed tray impression technique. The closed type impression uses the conventional closed tray and corresponding impression components, the operation is relatively simple, but the impression precision is lower, and the method is clinically suitable for the simple implantation repair of individual tooth loss or the preparation of an initial impression. The windowed die is characterized in that a windowed tray or a personalized tray and corresponding die components are used, the operation is relatively complicated, but the die precision is higher, and the windowed die can be used for planting and taking dies with a plurality of teeth missing. So that the artificial tooth is implanted for the patient without the dental jaw to repair, the model is taken by windowing.
When performing horizontal die taking of an implant for dentures without dental implant denture restoration, it is necessary to connect a die transfer bar with the implant, and then to fix the relative positions of the plurality of transfer bars, conventionally, clinically, a roughened steel wire or a photo-curable resin or the like is used to connect a connecting bar with the transfer bars, and the relative positions of the plurality of transfer bars are fixed by using the connecting bar as a medium, so as to determine the relative positions of the respective implants.
Dental implant denture restoration has strict requirements on patient conditions and clinical operation and experience of doctors, and windowed impressions also have the defect of complicated operation, two doctors are required to cooperate to operate conventionally, one doctor performs intraoral fixation of a connecting rod and a transfer rod when the connecting rod and the transfer rod are connected, and the other doctor performs intraoral operation, so that technical sensitivity is high. The experience and level of operation of a physician in the clinic will dictate to a large extent the time and accuracy of the operation. The steel wire material for connection has the defects of easy relative sliding and the risks of clinical complications such as physical trauma of oral mucosa; the resin material for connection has the defects of insufficient retention force and possible deformation and displacement due to limited strength, so that the accuracy of the impression is reduced, and meanwhile, if a doctor operates improperly, the resin enters the hole of the screw of the transfer rod and blocks the hole, so that the clinical operation difficulty and the operation time are greatly increased.
Disclosure of Invention
The invention aims to solve the problems, and provides a windowed impression connector for repairing a dental implant false tooth, which is a connector for conveniently and stably connecting each transfer rod with a connecting rod, so that the relative positions of each implant are transferred accurately, the operation time is shortened, the clinical efficiency is improved, and the accuracy of horizontal impressions of the implants is improved.
The technical scheme adopted by the invention is as follows:
the utility model provides a no tooth jaw implant artificial tooth restoration window formula impression connector, be fixed part in the middle of the transfer pole of impression, upper portion is the shaft shoulder, and the lower part is implantation portion, characterized by, the main part of connector is the plectane of taking the hole, and the diameter of hole is unanimous with the external diameter on transfer pole upper portion, and the side of connector is the square unanimous with transfer pole side radian, and square left and right sides is equipped with a ring respectively, is first ring and second ring respectively, and two rings are located two heights, become an angle between two rings, and two rings are used for connecting the connector in place ahead or rear respectively through the connecting rod.
Further, the first ring is located above the second ring, and the angle between the two rings is 30 degrees.
Further, the included angle between the first circular plane and the square plane is 90 degrees.
Further, the first circular plane is coplanar with the square plane.
Further, the diameter of the through hole of the circular plate was 1mm, and the outer diameter of the circular plate was 3mm.
Further, the transfer bar, the connecting bar, and the connector are fixed together by a photo-setting resin.
The beneficial effects of the invention are as follows:
(1) The operation difficulty of doctors for repairing the windowed impression of the dentures without dental implant can be effectively reduced, the operation time is fully shortened, and the clinical efficiency is improved;
(2) The accuracy of the implant horizontal impression is effectively improved, the risk of occurrence of clinical operation complications is reduced, and the convenience and the accuracy of the clinical operation of the dentures without dental implant denture restoration window impression are realized.
