Description

A kind of oral restoration tooth preparation axial plane degree of polymerization detector

Technical field

The utility model belongs to medical apparatus technical field more particularly to a kind of oral restoration tooth preparation degree of polymerization inspection Device.

Background technique

Tooth preparation is to guarantee that complete crown is worn not rotate or fall off into firm, is not difficult in place, there is the form in each face Strict requirements, so, the degree of polymerization is an important index, and clinically balancing run difficulty and actual needs, often choose one Fixed angular range, though currently, there is the equipment of measurement converging angle, most of volumes are larger, are unable to satisfy actual conditions Needs, great inconvenience is brought to patient, and the sight of observer is easily blocked at each position in oral cavity, alternatively, clinical On the experiences for relying on doctor most of for the prediction of the tooth body degree of polymerization, increase the work difficulty of doctor.

In conclusion problem of the existing technology is:

The equipment volume for measuring the tooth body degree of polymerization is larger, and equipment uses complex steps, and accuracy rate is low, gives doctor and trouble Person brings greatly pain and inconvenience.

Summary of the invention

In view of the problems of the existing technology, the utility model provides a kind of oral restoration tooth preparation axial plane degree of polymerization Detector.

The utility model is realized in this way a kind of poly- degree detector of oral restoration tooth preparation axial plane is provided with bottom end Positioning device, dead axle, upper end positioning device, connecting rod, hand holding handle front support bar, switch button, battery cap, pointer, arc Shape dial, display screen, pointer positive and negative rotation control button, hand holding handle.

Arc-shaped scale tail end is welded with bottom end positioning device, and bottom end positioning device is plugged with dead axle, is socketed on dead axle Pointer, bottom end positioning device tail end correspond to 90 ° of positions of arc instrument board, and arc instrument board front end is welded on end positioning device On, upper end positioning device is connected with connecting rod, and connecting rod is connected with hand holding handle front support bar, the connection of hand holding handle front support bar There is hand holding handle.

Further, switch button, display screen and pointer positive and negative rotation control button are installed on hand holding handle.

Further, hand holding handle end is equipped with battery cap.

The advantages of the utility model and good effect are as follows: the adaptation is novel to be provided with arc instrument board, more convenient for user The tooth body axial plane degree of polymerization intuitively observed and measured is equipped with pointer positive and negative rotation control button on hand holding handle, and user can be more Convenient to adjust pointer, bottom end positioning device and upper end positioning device determine optimal measurement position simultaneously, the utility model solution The biggish inconvenience of traditional inspection tooth preparation axial plane degree of polymerization difficulty of having determined, the utility model can be used for whether tooth body axial plane is deposited In undercut, to improve the success rate of tooth preparation, reduce rework rate, easy to operate, data are accurate, convenient for clinical expansion Using.

Specific embodiment

For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates Detailed description are as follows for attached drawing.

The structure of the utility model is explained in detail with reference to the accompanying drawing.

As shown in Figure 1, a kind of oral restoration tooth preparation axial plane degree of polymerization detector includes: bottom end positioning device 1, dead axle 2, upper end positioning device 3, connecting rod 4, hand holding handle front support bar 5, switch button 6, battery cap 7, pointer 8, curved scale Disk 9, display screen 10, pointer positive and negative rotation control button 11, hand holding handle 12.

Arc-shaped scale 9 is welded on end positioning device 3, and bottom end positioning device 1 is welded on the tail of arc-shaped scale 9 End, dead axle 2 are plugged in bottom end positioning device 1, and pointer 8 is socketed on dead axle 2, and upper end positioning device 3 is fixed on by nut In connecting rod 4, connecting rod 4 is fixed on hand holding handle front support bar 5 by nut, and hand holding handle front support bar 5 is connected with hand Hold handle 12.

Further, switch button 6, display screen 10 and pointer positive and negative rotation control button 11 are installed on hand holding handle 12.

Further, 12 end of hand holding handle is equipped with battery cap 7.

Working principle of the utility model is: first opening battery cap 7, it is packed into one piece of No. 7 battery, presses switch button After booting, 9 center of circle of arc-shaped scale is placed in above shoulder by upper end positioning device 3 and tooth long axile parallel alignment for 6 bootings Low side positioning device 1 is clamped securely, adjusts pointer 8 by pointer positive and negative rotation control button 11 and be bonded with abutment, directly by neck portion It connects and reads numerical value shown on display screen 10, the corresponding 90 ° of positions in 1 end of bottom end positioning device, therefore upward extended line and finger The angle β of needle 8 is tooth body axial plane polymerization degree, is determined whether in the normal range by comparing normal value.

The above is only the preferred embodiment to the utility model, is not made in any form to the utility model Limitation, it is all according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with Modification, is all within the scope of the technical scheme of the utility model.
