Description
Technical field
The utility model relates to medical instruments fields, are registrated fixed device more particularly to a kind of oral cavity implanting tooth.
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 work bone 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.The problems such as that there are operating process is complicated for the method for registering, puts benchmark dot center manually there are errors.
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.

The tooth crown height of tooth position.The preferred embodiment makes the U-shaped seat 10 tooth ruler as much as possible for adapting to human body different tooth position
It is very little, so that U-shaped seat 10 is more matched with the tooth size of human body different tooth position, it is applied widely, while alleviating patient's
Sense of discomfort.
Fourth embodiment
As shown in fig. 7, the utility model fourth embodiment discloses a kind of use such as first embodiment to 3rd embodiment
In any oral cavity implanting tooth be registrated the method that fixed device carries out oral cavity implanting tooth registered placement, comprising the following steps:
Step S1 covers plate lock on tooth, and control driving part, which pushes, abuts region, so that hollow base is towards U
The medial movement of type seat, so that the plate lock inner space width that U-shaped seat and hollow base are constituted is slightly larger than tooth width；
Step S2 places moulage on the inside of the plate lock that U-shaped seat and hollow base are constituted, plate lock is covered in tooth
On tooth；Wish that dental surface retains some moulages, which is a kind of silicon rubber, still has certain elasticity after solidification, plays
Soft lining effect, enhancing plate latch clamping force.
Step S3, after moulage solidification on the inside of the plate lock that U-shaped seat and hollow base are constituted, control driving part is pushed away
Dynamic to abut region, so that medial movement of the hollow base towards U-shaped seat, plate lock clamps inside moulage and tooth；
Step S4 removes plate lock from tooth, latches upper connection support bar in plate, and connect and show on support rod
Film shoots CBCT so that wearing oral cavity implanting tooth in patient mouthful and being registrated fixed device；
Step S5, removes developer sheet, and tracing positioner is connected on support rod, is matched automatically by the realization of its built-in algorithm
It is quasi-.
The present embodiment applies double shield in terms of maintenance, and the rapid prototyping material of stamp is to have elasticity after solidifying
Moulage, plate lock after locking, solidify after moulage can form good maintenance and locating effect, the only company of need
Continuous two teeth can be obtained enough retentions.In the present embodiment, flexible stamp after solidification is placed in plate lock
There are two effects for material, first is that printing off tooth contour, realize positioning；Two are to provide a kind of soft lining, enhance clamping force.The present embodiment
Using matched support rod, developer sheet, tracing positioner, realizes and keep track in autoregistration and art, autoregistration improves
The manual registration step problem big with error repeatedly, reduces doctor's operating process, clinical application is easier.In the present embodiment
The material that x-ray development degree can be used low in preferred embodiment can avoid strong developing material and generate artifact, and then influence diagram image quality
The occurrence of amount.
The utility model is illustrated below with reference to a specific embodiment.In hollow base 12 and the common structure of U-shaped seat 10
At silicon rubber is filled in the plate lock for clamping tooth, stamp is carried out.It should be added that the range of stamp: doing two
The tooth on side, generally folder labial teeth do intermediate general folder two sides, will not clip to very the inside, and after silica gel plug is entered, silica gel may be from
It is come out in the hole of support rod.12 outside of hollow base when being screwed into bolt, can be squeezed hollow base 12 toward tooth direction by bolt hole, from
And it is clamped with tooth.To get to a tooth model after equal silicon rubber are hard.Support rod 14 and U-shaped seat 10 are (medical with medical glue
Quick-drying gelatin) connection, this device is fixed to by support rod 14 and developer sheet 16 first with being threadedly coupled again after the positioning of location hole 166
The tooth of patient.At this point, stamp is completed at plate lock, therefore duplicate the effect of positioning.Patient is with above-mentioned
Whole device claps CBCT (conical beam CT), and developer sheet 16 can be removed after having clapped.Developer sheet 16 includes entire alveolar bone as possible,
It can make to be registrated more acurrate.The part of development has a relative position with tooth.After CBCT has been shot, developer sheet 16 is changed into and is chased after
Track device enables optical tracking instrument to track black and white point of interface.Load onto the hand that can start oral cavity implanting tooth after follow-up mechanism
Art.
In conclusion a kind of oral cavity implanting tooth involved in the utility model be registrated fixed device and method have it is very high
