The utility model provides a navigation head has better laminating degree with tooth body, no longer relies on the doctor and just can pinpoint, reduces the cutting of tooth body tissue, reduces the probability of patient's odontoclasis, guarantees going on smoothly of root -canal therapy.
Description
Technical field
This utility model belongs to medical assistance technique with the apparatus field, oral cavity, is specifically related to a kind of leading for root canal
Boat device.
Background technology
Flourish along with digitalized oral cavity Medical Technology, utilizes dentistry cone beam CT scan to obtain
Take portion's root canal morphology in tooth body effectively to assist doctor successfully to carry out tooth root canal to become a reality.
The patent application of Application No. 201510167190.0 discloses a kind of tooth for root canal and opens marrow method
And device, the method is to intercept described to suffer from Ya Chu centre position from the computer tomography CT of target tooth is cut into slices
Image, by described image slice is carried out separation calculation, obtain the threedimensional model of described target tooth；From bag
CT image containing target tooth is partitioned into the root pipe of described target tooth, and isolates the epimere root of preset length
Pipe；Extract the centrage of split root pipe, calculate the intersection point at described center and described target tooth threedimensional model；With
Described center is reference point with the intersection point of described target tooth threedimensional model, adjusts point of penetration according to concrete graphical analysis
Position also utilizes what navigation system finally determined described target tooth to open marrow position.Although this method need not doctor
Remove whole roof of pulp chamber by treatment tool and just can more accurately determine the position of root pipe, thus be significantly reduced access cavities
Diameter and preserve the dentin of pulp chamber sidewall to greatest extent, reduce patient and the probability of odontoclasis occur, but this device
Simply a kind of virtual bench, doctor simply can be understood by this virtual bench accurately determine root pipe open marrow position,
Practical operation is also intended to rely on doctor self to its assurance and feel, therefore, the anthropic factor thus brought without
Its therapeutic effect is more or less brought adverse effect by doubtful meeting.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, first to provide a kind of leading for root canal
Boat device, this device can directly help what it precisely determined root pipe to open marrow position in the actual therapeutic of doctor operates
And open the marrow degree of depth, improve the operation precision of root canal, it is ensured that treatment safety.
The guider for root canal that this utility model provides, this device is by plywood, guide post and work
Length mark dish is constituted, plywood be one with suffer from tooth or suffer from the tooth crown shape of tooth and the part tooth of neighbouring single or whole teeth
The cage plate of coupling, its thickness is 0.5～3.0mm, has exposure mouth corresponding with suffering from root canal position；Cutting of guide post
Face shape is inverted "L" shaped, and is connected as a single entity with plywood by the termination of vertical section, and the termination of horizontal segment has one and lacks
Mouthful, the edge in breach is corresponding with suffering from root canal approach respectively, between lower surface and the plywood upper surface of horizontal segment
Distance at least 1.5mm；Active length labelling dish is the disk of perforate in the middle part of in the of, be movably fixed to split brill, expand or
On file, its lower surface mates spacing with guide post breach upper surface, makes to split brill, expansion or front end of file and reaches exactly to suffer from tooth
Bottom root pipe.
Plywood described in above guider preferably one at least holds corona and closes the cage plate in face, more preferably holds tooth
The cage plate in hat conjunction face 1/4～1/2；Exposure mouth on plywood preferably intersects with tooth crown surfaces suffering from Ya Gegen pipe approach
Centered by place, the length and width outwards opened is at least the rule of 2.0mm or irregular aperture respectively.
Breach on guide post horizontal segment described in above guider is towards outside mouth, in order to doctor operates.
Compared with prior art, this utility model has the advantages that
1, the guider provided due to this utility model is not only an entity apparatus, and drawing of wherein arranging on plywood
Guide pillar can be positioned at split bore or expand file on active length labelling dish coordinate accurately determine out marrow direction and open marrow deep
Degree, thus in root canal operation process, eliminate the reliance on doctor self to its assurance and feel, can eliminate artificial
Therapeutic effect is brought adverse effect by factor, and can reduce tissue of tooth cutting on the premise of being accurately positioned,
Reduce the probability of patient's odontoclasis, it is ensured that being smoothed out of root canal.
2, owing to having the bigger rule of an area on the guider plywood of this utility model offer or irregularly exposing
Aperture, thus during the use of this guider, not only can make to split facing when facing is cut in drilling is externally exposed,
It is easy to doctor and observes open surgery district, it is ensured that treatment safety, and the water also allowing for dental handpiece ejection can be direct
Cutting facing is cooled down, it is to avoid in working angles, facing is heated the pessimal stimulation excessively caused.
