Description
Technical field
The present invention relates to area of medical devices, more particularly to a kind of oral cavity abutment preparation method.
Background technology
Existing oral cavity abutment preparation method relies on doctor's gimmick with experience more, and difficulty of starting with is big, and human factor produces error
It is more, mainly there is following deficiency：
(1) the standby tooth time is grown, and half an hour, at most a few hours, patient are big by pain at least；
(2) some doctors experiences deficiency, stable preparation is unable to reach during standby tooth, it may appear that prepare that track is rough not to be connected
Continuous situation；
(3) doctor carries out standby tooth with conjecture, cause unnecessary mistake by rule of thumb in the place that some are not so sure, meeting
By mistake；
(4) occlusion can not be contrasted during standby tooth, the occlusion space of preparation may deficiency.
The content of the invention
To solve the problems, such as that human factor generation error is more in existing abutment preparation process, the present invention proposes a kind of numeral
Change oral cavity abutment preparation method.
The technical proposal of the invention is realized in this way：
A kind of digitalized oral cavity abutment preparation method, comprises the following steps：
Step (a), bored using mobile phone and grind basic point；
Step (b), patient's oral condition is scanned using intraoral scanner；
Step (c), cast trimming and abutment form Design are carried out using software after scanning, preserve file；
Step (d), the file preserved in step (c) is imported into cutter track software for calculation, made with the basic point of mark in step (a)
For cutter track starting point, the cutter track file for calculating completion will be introduced directly into the control system of automatic standby tooth machine；
Step (e), by the basic point in automatic standby tooth locomotive pin perpendicular alignmnet jaw face, start the cutter track file in step (d),
Start cutting and prepare abutment；
Step (f), cutting are completed, and are completed abutment and are prepared.
Alternatively, the step of being scanned using intraoral scanner to patient's oral condition, including：Lower jaw scanning, the upper jaw
Scanning, occlusion scanning, the place progress both sides that prepare abutment face tooth and jaw tooth are scanned.
Alternatively, the step of carrying out cast trimming and abutment form Design using software after scanning, including：
Step (c1), cast trimming：Using dressing tool, cut remote from abutment, scan incomplete region, edge line with
Lower 2mm gum portion is deleted；Check whether the occlusion of scanning stings tightly, such as occlusion does not need tightly to rescan；
Step (c2), abutment form Design：Abutment is cut into trapezoidal and undercut area is not present, is repaiied using wax spatula instrument
It is whole；Maxillary region point reserves occlusion space according to occluding relation；The abutment progress smooth treatment subtracted will be repaiied using smooth tool.
Alternatively, in the step (e), the car pin that actionradius is 0.1 is cut.
The beneficial effects of the invention are as follows：
(1) abutment is prepared beforehand through Software for Design, preview, because of artificial or other factors damage abutment or tooth will not be faced；
(2) operating time is short, and the preparation process of each abutment only needs 1 to 2 minutes, and the pain of patient is minimized；
(3) precision of equipment is high (cutting accuracy is 10 microns), is not in that abutment surface is uneven, rough
Situation；
(4) whole dental arch can be seen clearly using intraoral scanner, it is simple to operate without using the aids such as mouth mirror；
(5) cutting effect can be observed by software preview to determine cutting position in some uncertain places of tooth.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is a kind of flow chart of digitalized oral cavity abutment preparation method of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Before abutment is prepared using the method for the present invention, doctor and patient do preparation before standby tooth, are opened using oral cavity
Lower jaw on mouthpart immobilized patients, the saliva of dental arch surface is dried up with air gun.
Next, standby tooth is carried out by the digitalized oral cavity abutment preparation method of the present invention, as shown in figure 1, including following
Step：
Step (a), bore one, mill using high speed handpiece and make perpendicular to the hole that jaw level is a diameter of 0.15mm of 0.1mm
For Home basic points.
Step (b), patient's oral condition is scanned using 3Shape intraoral scanners, including lower jaw scanning, the upper jaw
Scanning, occlusion scanning, the place that prepare abutment carries out rescanning, including tooth is faced and to jaw tooth in both sides.
Step (c), cast trimming and abutment form Design are carried out using software after scanning, specifically includes following steps：
Step (c1), cast trimming：Using dressing tool, cut from abutment farther out, scan incomplete region, edge line
Following 2mm gum portion is deleted；Check whether the occlusion of scanning stings tightly, such as occlusion does not need tightly to rescan；
Step (c2), abutment form Design：Making baking-ceramic tooth, then abutment needs switchback to fall 1.5mm-1.8mm, if entirely
It is 0.3mm-0.8mm to be preced with tooth switchback space, and design principle is to be cut into trapezoidal by abutment and undercut area is not present, and uses wax spatula instrument
Repaired, the minimum of neck finishing is maximum close to most close to minimum value (porcelain 1.5mm, complete crown 0.3mm), the finishing of cut end part
Big value (porcelain 1.8mm, complete crown 0.8mm)；Maxillary region point reserves occlusion space (porcelain 1.8mm, complete crown according to occluding relation
0.8m)；To repair the abutment that has subtracted using smooth tool and carry out smooth treatment, and make abutment surface continuous and smooth, with this data with
Method prepares tooth, and the artificial tooth that post-production goes out is 86% with former tooth similarity, preserves file.
Step (d), the file preserved in step (c) is imported into cutter track software for calculation, made with the basic point of mark in step (a)
For cutter track starting point, the cutter track file for calculating completion will be introduced directly into the control system of automatic standby tooth machine.
Step (e), the Home basic points in automatic standby tooth locomotive pin perpendicular alignmnet jaw face, start starting device power supply
