Description

Technical Field

[0001] The invention relates to the technical field of oral implantation, in particular to an oral implantation positioner. Background Art

[0002] Dental implant refers to a method of restoring missing teeth by using the lower structure implanted in the bone tissue as the basis to support and retain the upper dental restoration. It consists of two parts: the lower supporting implant and the upper dental restoration. It is mainly used for the treatment of tooth defects and missing teeth. When implanting teeth, it is necessary to measure the size of the adjacent teeth and move the middle position for positioning. A hole is drilled in the alveolar bone in the middle of the missing position. If the hole is off-center, it will affect the subsequent force on the denture. If the hole is re-drilled, it may cause damage to the alveolar bone and increase the patient's discomfort. Therefore, a positioner is needed to position the alveolar bone when drilling. Most existing positioners can position the middle position according to the adjacent teeth, but the positioning effect of the inward and outward angles of the drilling hole is not good.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the setting of two extension plates, the two extension plates are inserted into the missing position of the teeth, and the extension plates slide along the arc rail. The two extension plates are respectively in contact with the teeth on both sides of the missing position, and the extrusion spring squeezes the two long rods 1, so that the two long rods 1 are opened and separated, so that the two extension plates are pushed to slide away from each other through the long rod 1, and the sliding setting of the slider 1 and the long rail rod makes the deviation angle of the extension plates to both sides the same, so that the mounting seat is always located in the middle position of the two extension plates, so that it is convenient to locate the positioning tube in the middle position of the two adjacent teeth, and the positioning tube is located in the middle position between the two adjacent teeth through the central setting of the slide rod 1 between the two extension plates, and the drill bit is guided by the positioning tube to facilitate drilling on the alveolar bone.

[0017] 2. By setting the transmission mechanism, the shell is pushed so that the contact plate contacts and fits with the tooth surface of the adjacent tooth, so that the contact plate adapts to the eversion or inversion angle of the adjacent tooth. The deflection of the contact plate drives the gear 2 to rotate, and the rotation of the gear 2 drives the long rod 3 to move along its own length direction. The movement of the long rod 3 drives the spur plate 1 to move through the transmission mechanism, so that the spur plate 1 moves the same distance along its own length. By setting that the two spur plates 1 are meshed with the gear 1, the two spur plates 1 drive the center position of the gear 1 to move, and the moving distance of the gear 1 is the moving distance of the two spur plates 1. The movement of gear one drives straight tooth plate two to move through slide bar one, and straight tooth plate two drives the positioning cylinder to rotate through arc tooth plate, so that the rotation angle of the positioning cylinder is half of the sum of the inward and outward turning angles of the two contact plates, so that the position of the positioning cylinder is located in the middle of the two adjacent teeth, and the inward and outward turning angle of the positioning cylinder is also located in the middle of the inward and outward turning angles of the two adjacent teeth, so that when the contact plate fits with the tooth surface, the deflection angle of the positioning cylinder is only related to the inward and outward turning angles of the adjacent teeth on both sides, and the deflection angle of the shell has no effect on the angle of the positioning cylinder, thereby facilitating operation.
