Description
Technical field
The present invention relates to a kind of making for repairing impression tray, and in particular to a kind of Dental implantion repairs the design of individual tray
Preparation method.
Background technology
When more Dental implantions are repaired, fenestration stamp can effectively improve each planting body locus, the essence of attitude information record
Exactness.Clinical conventional pallet makes method two by hand including ready-made tray punch method, self-solidifying or photosensitive resin piece both at home and abroad at present
Kind, main advantage and disadvantage are as follows：
1st, ready-made tray punch method：The punching of sold resin pallet is more convenient, without producing preliminary impression and perfusion plaster cast,
Clinician can be operated by simple hand and be completed.But difference of hardness, easily cause the deformation of final impression, influence impression accuracy.
2nd, self-solidifying or photosensitive resin piece make method by hand：Various clinical make can be achieved to require, but preliminary impression must be filled
Plaster cast is made as, and needs special equipment, material piece, cost is higher.And special messenger is needed to spend 1-2 hours to have made
Into efficiency is low, can not be done directly application in clinic.
3rd, due to being operated using range estimation by hand, above two method is difficult to the homogeneity of final impression material thickness,
Production effect is had a great influence by operator's experience, influences impression making precision indirectly.
The content of the invention
It is an object of the invention to provide the designing and manufacturing method that a kind of Dental implantion repairs individual tray, with Design of digital and
The Dental implantion of making, which repairs individual tray and substitutes traditional-handwork, to be made, and realizes that clinical oral is increasingly automated, high accuracy makes tooth
The target of individual tray is repaired in plantation, can be effectively improved clinical fenestration plantation reparation individual tray in a short time and be designed and produced
Level, improve diagnosis and treatment efficiency and quality.
In order to achieve the above object, the present invention has following technical scheme：
A kind of Dental implantion of the present invention repairs the designing and manufacturing method of individual tray, comprises the following steps：
1st, a kind of digitlization preparation method of edentulous jaw personalization impression tray, comprises the following steps：
1) single jaw denture preliminary impression where producing planting body with ready-made tray and alginates, and irrigate plaster cast；
2) preliminary impression or scanning plaster cast are directly scanned with dentognathic model spatial digitizer, obtains denture preliminary impression or stone
The three-dimensional data of cream model tissue surface form；
3) scan data is called in into reverse engineering software, extraction preliminary impression mucous membrane fold line is edge line, using edge line as
Border, intercept internal cloud data；
4) in reverse engineering software platform, cloud data inside the fold line of the edentulous jaw preliminary impression of corresponding step 3),
Choose oneGum to enter a direction, fill and lead up all undercut areas in this direction, obtain the surface cloud data of no undercut；
5) cloud data is offset into 2-3mm along the normal direction of the surface cloud data in step 4), it is uniform reserves final impression material
Consistent three dimensions, obtain virtual pallet inner surface；
6) along virtual pallet inner surface normal direction by inner surface 1~3mm of uniform thickened, the pallet table in planting body corresponding region
Stamp bar punched out is reserved in face, obtains virtual tray main body part；
7) the virtual tray handle of the upper jaw is designed as straight rectangle, it is triangle that the virtual tray handle of lower jaw, which is designed as end,
Handle；
8) data boundary of virtual tray main body part and handle is merged, obtains Dental implantion and repair individual virtual pallet
Intact form data, preserved with STL forms；
9) STL data described in step 8) is imported into the computer system that is connected with 3D printing equipment, by 3D printing equipment,
Make indivedual impression trays of hard resin material.
Wherein, the step 5) is to offset 2-3mm along alveolar ridge surface normal.
The advantage of the invention is that：
The designing and manufacturing method that a kind of Dental implantion repairs individual tray is provided, repaiied with Design of digital and the Dental implantion made
Individual tray substitutes traditional-handwork making again, realizes that clinical oral is increasingly automated, high accuracy making Dental implantion reparation is indivedual and holds in the palm
The target of disk, clinical fenestration plantation reparation individual tray can be effectively improved in a short time and designs and produces level, improves diagnosis and treatment
Efficiency and quality.
