Measuring and positioning tool for oral implantation

Abstract

The invention relates to the technical field of oral cavities, and discloses an oral implant measuring and positioning tool which comprises a grip, a first side plate and a second side plate are movably mounted on the upper surface of the grip through pin shafts, and opening mechanisms are arranged on the surfaces of the first side plate and the second side plate. And the opposite sides of the first side plate and the second side plate are fixedly connected with fixed seats. According to the oral implant measuring and positioning tool, through cooperative use of an auxiliary mechanism and a measuring mechanism, a guide plate and a measuring plate are placed on the two sides of adjacent teeth needing to be implanted, a main gear is rotated to drive an auxiliary gear on the main gear to rotate, and through the proportional structural design of the main gear and the auxiliary gear, when the measuring plate moves, the measuring plate can be accurately positioned; the positioning plate only moves by half of the moving distance of the measuring plate, so that the midpoint between the guide plate and the measuring plate can be displayed at any time, the planting point can be positioned more visually, meanwhile, the cost is saved, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to the field of oral cavity technology, in particular to an oral cavity implant measuring and positioning tool. Background technique [0002] The oral cavity is the beginning of the digestive tract. The anterior cleft communicates with the outside world, and the posterior pharynx connects with the pharynx. There are teeth, tongue and other organs in the oral cavity. The front wall of the oral cavity is the lips, the side wall is the cheek, the top is the palate, The floor of the oral cavity is composed of mucous membranes and muscles. The oral cavity is divided into the anterolateral oral vestibule and the posteromedial oral cavity by means of the upper and lower dental arches. The gap behind the third molars is connected. Clinically, when the patient's trismus is closed, a gag or cannula can be placed through this passage to inject drugs or nutrients while preventing tongue bite.

Problems solved by technology

[0003] When implanting a patient’s teeth, it is necessary to determine the implantation point in advance. However, most of the traditional methods of collecting implantation points use the implant positioning ruler to locate the implant position. When positioning, the implant positioning ruler is inserted into the area to be implanted. Between the two adjacent teeth in the area to be implanted, read the distance between the two adjacent teeth according to the scale on the implant positioning ruler, and calculate the middle position between the two adjacent teeth as the positioning position according to the distance , but because it requires multiple data supports for calculation, not only the operation is inconvenient, but also the implant position cannot be intuitively displayed in the oral cavity, which is not conducive to the accuracy of positioning, and some smart devices are used for 3D modeling Acquisition and positioning. Although this method has high precision, it is expensive and not easy to be widely used. Therefore, a dental implant measurement and positioning tool is proposed.
