Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to an oral implant positioner with an alveolar ridge bone morphology measurement function. Background Art

[0002] There are many ways to repair missing teeth, and dental implants have gradually become a mainstream choice. The basic principle of oral implant technology is to implant a threaded cylindrical artificial tooth root into the alveolar bone. After the implant and the bone form bone fusion, the abutment is connected to the upper end of the implant to repair the crown. It can be seen that the basis of dental implants must have a sufficient amount of bone, and the most critical factor that determines the success of implants is whether the implant can obtain sufficient bone support. The oral implant locator is a special tool for digital dental implant surgery. The use of the dental implant locator allows the doctor to perform dental implant surgery completely according to the angle and depth designed before the operation, which greatly improves the success rate of the operation and reduces the pain of the patient.

[0003] In the existing process of tooth repair and implantation, an implant locator is generally used. Before implantation, it is necessary to use an implantation machine to measure inside the oral cavity. It is impossible to measure the alveolar ridge bone morphology. During the measurement process, the patient needs to keep his teeth open. This continuous action may cause discomfort to the patient and reduce the comfort of use. Some patients may suddenly close their teeth, which brings inconvenience to oral implantation. Therefore, we propose an oral implant locator with alveolar ridge bone morphology measurement function to solve this problem. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By setting a fixed rod, the fixed rod and the inside of the shell are fixedly installed and cannot be moved. The rotation of the threaded rod can drive the movable rod to move, so that the fixed rod and the movable rod can only be closed equidistantly towards each other, or relatively opened, thereby changing the distance between the fixed rod and the movable rod. The first bearing can facilitate the rotation of the threaded rod. The elastic force of the spring and the strip-shaped limit hole play a limiting role, so that the fixed rod and the movable rod can move in the area of ​​the strip-shaped limit hole. The anti-slip rod, the scale ring and the scale table are arranged to effectively eliminate the errors caused by long-term use, further improve the measurement accuracy of the device, and effectively increase the service life of the device.

[0013] 2. By providing a rotating disk, a rotating rod is fixedly installed on the upper side of the rotating disk, which can increase the contact area between the rotating disk and the hand, making it easier to adjust the threaded rod and the fixed rod.

[0014] 3. Through settings, the rack limit block and the non-toxic silicone pad can be fixed together as needed to improve the comfort of measurement.

[0015] 4. By arranging the second bearing, the positioning screw and the internal threaded sleeve, they are always located on the angle bisector between the two arms, so as to achieve more convenient orientation and positioning of the L-shaped rod.

[0016] 5. By setting the fixing plate, the abutment rod, the through hole and the positioning pin in coordination with each other, the length of the abutment rod can be adjusted so that the index tip contacts the upper end of the alveolar ridge to form a position. The positioning pin is supported by cast steel material, which is more conducive to the use of the equipment.

[0017] 6. By setting a handle, it is convenient for medical staff to hold the medical device, increase the contact area between the hand and the shell, and facilitate the picking up of the shell. The use of an anti-slip pattern cover can conveniently protect the handle, increase the contact area between the hand and the handle, and enhance the friction between the hand. At the same time, the handle can be better protected to play an anti-slip role. BRIEF DESCRIPTION OF THE DRAWINGS
