Intraoral In-place Tract Viewer

Abstract

An intraoral insertion path visualizer is applied in the field of oral fixed prosthesis, especially in fixed prosthodontics requiring that abutments share the same insertion path. The intraoral insertion path visualizer mainly comprises two parallel visualizing rulers, a crossbeam and a handle. One of the visualizing rulers is disposed at an end of the crossbeam and is rotatable, and the other visualizing ruler is disposed at the other end of the crossbeam and can slides in a sliding groove in the crossbeam. The handle is flat so that the handle is convenient to grasp. The intraoral insertion path visualizer is characterized in that: during a visualizing process, the sharp end of one of the visualizing rulers is disposed at the shoulder of an abutment and the sharp end of the other visualizing ruler is disposed at the shoulder of another abutment, and therefore the same insertion path of the abutments can be visualized. One of the visualizing rulers is fixed relatively and the other visualizing ruler can be adjusted by allowing the visualizing ruler to slide along the crossbeam according to the different distances between the two abutments. The two visualizing rulers are both rotatable so as to suit each axial surface of the abutments.

Description

technical field [0001] The patent of the present invention is applied in the field of oral fixed restoration, especially in the fixed denture restoration requiring a common fitting path between abutment teeth. Background technique [0002] In the current fixed denture restoration process, the determination of the common positioning path after tooth preparation mainly depends on the operator's experience, but this has great inaccuracy, especially for beginners, it is difficult to grasp, and the axial convergence is too large On the one hand, too much tooth tissue will be removed, and on the other hand, it will affect the retention of the fixed denture; if the amount of tooth grinding is insufficient and there is a tooth undercut, the fixed denture cannot be in place, such as filling the undercut The correct method will affect the precision of the denture. For those who are not easy to determine the common positioning path, some operators take the dental model, then pour the ...

[0002] In the current fixed denture restoration process, the determination of the common positioning path after tooth preparation mainly depends on the operator's experience, but this has great inaccuracy, especially for beginners, it is difficult to grasp, and the axial convergence is too large On the one hand, too much tooth tissue will be removed, and on the other hand, it will affect the retention of the fixed denture; if the amount of tooth grinding is insufficient and there is a tooth undercut, the fixed denture cannot be in place, such as filling the undercut method, it will affect the precision of the denture

For those who are not easy to determine the common positioning path, some operators take the dental model, then pour the plaster model, and then observe it on the model observer, and then go to the patient's mouth to prepare the tooth according to the observation result, which increases the work. volume, which increases patient visit time
