Description
Technical field
The present invention relates to medical instruments fields, more particularly to a kind of oral cavity implanting tooth registered placement device and method.
Background technique
Tooth-implanting is comfortable, beautiful, durable and do not damage adjacent teeth, is preferred recovery scenario after current absence of tooth.Plantation
Tooth, which refers to, is anchored at the pure titanium of root type or titanium alloy material in jawbone, provides support and fixation for the reparation of missing tooth.Oral cavity kind
The theory and technology of plant is synosteosis, i.e., orderly or stock is deposited directly to implant surface, and planting body is anchored in bone.Bone knot
The quality of conjunction is directly related to the success or failure and long-time stability of tooth-implanting.The many because being known as of synosteosis are influenced, wherein critically important
One be exactly planting body position and axial direction, if bone regeneration around implant bone amount be less than 1.5mm, it may occur however that bone regeneration around implant bone
It absorbs；If planting body cannot be towards to jaw tooth function point, planting body may bear too strong lateral force, it is equally possible to cause to plant
Bone resorption around implant.Decline while this bone resorption is often reflected in synosteosis quality substantially reduces making for tooth-implanting
Use the time limit.
Preoperative Method is planted to be unfolded around CT data, first is that prepare for CT data with being registrated for entity information, two
It is the design that operation plan is completed in CT image.CBCT (Cone Beam Computed Tomography) refers to pencil-beam
It throws and recombinates fault image means according to computer, be plantation preoperative evaluation sclerotin bone amount, the common means of design scheme, but CBCT schemes
As and the Plant plane that wherein designs can not directly together with the entity relationship of oral cavity, in order to by two kinds of data integrations together,
It needs to carry out registered placement.
Existing method for registering mostly uses a method for registration, i.e., the multiple datum marks of attachment clap CT, base in pre-operative patients mouth
Coordinate on schedule is saved in virtual three dimensional image；With punctual, these datum marks are still adhered in mouth, pass through the seat of more datum marks
Mark realizes registration.For point on time, the instrument with inductor puts benchmark in outlet according to the sequence of datum mark in CT image one by one
The central point of point.That there are operating process is complicated for the method for registering, and putting benchmark dot center manually has error.
Existing registered placement is mostly to print off tooth model by quick moulding material, is fallen using between tooth neck or tooth
Recessed maintenance, since single tooth undercut retention is weak, so needing to carry out stamp to more teeth even half mouthful of tooth simultaneously.This method pair
Tooth contour dependence is larger, in order to obtain enough retentions, it is often necessary to use more (> 2) continuous teeth, be applicable in model
It encloses limited.Therefore this method is not suitable for the more patient of agomphosis, and patient's sense of discomfort is strong.
Summary of the invention
The invention discloses a kind of oral cavity implanting tooth registered placement device, including fixing seat and pass through bolt shaft and fixation
The sliding seat of seat rotation connection, the bottom edge of fixing seat and sliding seat respectively to each other opposite inside be bent and protruded to be formed it is solid

The method of one oral cavity implanting tooth registered placement device progress tooth-implanting registered placement, comprising the following steps:
S1, placed on the inside of the U-shaped padlock that fixing seat and sliding seat are constituted as can shape-changing material, U-shaped padlock is covered
On tooth；
S2, control driving structure push bearing surface, and sliding seat is around bolt shaft rotation, so that driven hook curves inwardly, U
Type padlock applies pressure to photo-curing material；
S3 stops pushing bearing surface after photo-curing material prints off teeth patterning and maintenance tooth under pressure, will
The pressure that U-shaped padlock applies is kept；
Light-solidified lamp is placed in the outside of U-shaped padlock by S4, so that the photo-curing material that stamp is teeth patterning solidifies；
S5 connects autoregistration device on oral cavity implanting tooth registered placement device, so that wearing tooth-planting in patient mouthful
Tooth registered placement device shoots CBCT；
S6 removes autoregistration device, tracing positioner is connected on oral cavity implanting tooth registered placement device, by built in it
Algorithm realizes autoregistration.
The present embodiment applies double shield in terms of maintenance, and the rapid prototyping material of stamp is photo-curing material, lock
Moulage after next U-shaped padlock, solidification can form good maintenance and locating effect, only need continuous two teeth
Obtain enough retentions.Light-solidified lamp is placed in the outside of U-shaped padlock by the present embodiment, can directly be realized outside U-shaped padlock
Photocuring avoids removing U-shaped padlock before moulage is unhardened and material is caused to deform.The present embodiment uses matched autoregistration
Device, tracing positioner realize and keep track in autoregistration and art, and autoregistration improves manual registration step repeatedly and error
Big problem, reduces doctor's operating process, and clinical application is easier.X can be used in the preferred embodiment of the present embodiment
The low material of line development degree can avoid strong developing material and generate artifact, and then the occurrence of influence picture quality.In this implementation
In one of example preferred embodiment, so that the photo-curing material cured curing time that stamp is teeth patterning is 30s, it can
Obtain preferable solidification effect.
In conclusion a kind of oral cavity implanting tooth registered placement device and method according to the present invention are with very high practical
Value.In addition, the principle of the present invention and its effect is only illustrated in the above embodiment of the present invention, not for limiting this hair
It is bright.Anyone skilled in the art all without departing from the spirit and scope of the present invention, to above-described embodiment carry out modification or
Change.Therefore, those skilled in the art completed without departing from the spirit and technical ideas disclosed in the present invention all etc.
Modifications and changes are imitated, should be covered by the claims of the present invention.
