Abstract

The invention relates to a design production method of a dental implantation repair individual tray. The design production method comprises: preparing an initial impression, and filling a plaster model; scanning the initial impression or plaster model; transferring the scanning data into a reverse engineering software, and extracting the cloud data of the tissue surface points inside the initial impression mucous membrane folding line; filling the inverted concave region; uniformly amplifying 2-3 mm along the data surface normal direction to obtain a virtual tray inner surface; uniformly thickening 2 mm along the virtual tray inner surface normal direction; reserving an impression rod penetrating hole on the surface of the tray in the implant corresponding region; designing a maxillary virtual tray handle and a mandibular virtual tray handle; and carrying out boundary fusion on the virtual tray inner surface data, the outer surface data and the handle data, storing in the STL format, and producing the edentulous personalized impression tray having the resin material through 3D printing equipment. According to the present invention, the produced dental implantation repair individual tray using the digital designing can replace the traditional hand-made production, and the precision of the opening implantation impression is easily improved.

Description

A kind of Dental implantion repairs the designing and manufacturing method of individual tray

Technical field

The present invention relates to a kind of making repairing impression tray, be specifically related to a kind of Dental implantion reparation The designing and manufacturing method of individual tray.

Background technology

When many Dental implantion are repaired, fenestration die can be effectively improved each implantation body locus, appearance The degree of accuracy of state information record.The most clinical conventional pallet includes that ready-made tray punches Method, self-solidifying or photosensitive resin sheet make method two kinds by hand, and main pluses and minuses are as follows:

1, ready-made tray punch method: the punching of sold resin pallet is more convenient, it is not necessary to produce just print Mould and perfusion plaster model, clinician can have been operated by simple hand.But difference of hardness, It is easily caused the deformation of final impression, affects impression accuracy.

2, self-solidifying or photosensitive resin sheet make method by hand: can realize various clinical making requirement, But preliminary impression must be recorded as plaster model, and need special equipment, material piece, cost Higher.And need special messenger to spend 1-2 hour can to complete, efficiency is low, it is impossible in clinic It is done directly application.

3, owing to using manual range estimation operation, above two method is all difficult to final impression material The homogeneity of material thickness, makes effect relatively big by operator's experience influence, remote-effects die system Take precision.

Summary of the invention

It is an object of the invention to provide a kind of Dental implantion and repair the designing and manufacturing method of individual tray, Repair individual tray with the Dental implantion of Design of digital and making and substitute traditional-handwork making, it is achieved Clinical oral is increasingly automated, high accuracy makes Dental implantion and repairs the target of individual tray, can be It is effectively improved clinical fenestration plantation reparation individual tray in short time and designs and produces level, improve Diagnosis and treatment efficiency and quality.

In order to achieve the above object, the present invention has a following technical scheme:

A kind of Dental implantion of the present invention repairs the designing and manufacturing method of individual tray, including following step Rapid:

1, the digitized preparation method of a kind of edentulous jaw personalization impression tray, including following step Rapid:

1) produce implantation body's place list jaw denture preliminary impression with ready-made tray and alginate, and fill Note plaster model；

2) directly scan preliminary impression or scanning plaster model with dentognathic model spatial digitizer, obtain Take denture preliminary impression or the three-dimensional data of plaster model tissue surface form；

3) scan data being called in reverse engineering software, extracting preliminary impression mucosa fold line is limit Edge line, with edge line as border, intercepts internal cloud data；

4) in reverse engineering software platform, corresponding step 3) the returning of edentulous jaw preliminary impression The internal cloud data of broken line, chooses one | tooth closes | gum to enter a direction, fill and lead up in the direction All undercut districts, it is thus achieved that without the surface cloud data of undercut；

5) along step 4) in the normal direction of surface cloud data cloud data is offset 2-3mm, The three dimensions of reserved final impression material uniformity, it is thus achieved that virtual pallet inner surface；

6) along virtual pallet inner surface normal direction by inner surface uniform thickened 1～3mm, in implantation body The tray surface of corresponding region reserves die bar punched out, it is thus achieved that virtual tray main body part；

7) virtual for upper jaw tray handle being designed as straight rectangle, the virtual tray handle of lower jaw sets It is calculated as the handle that end is triangle；

8) data boundary of virtual tray main body part and handle is merged, it is thus achieved that Dental implantion is repaiied The intact form data of multiple individual virtual pallet, preserve with STL form；

9) by step 8) described in STL data import the computer system that is connected with 3D printing device System, by 3D printing device, makes indivedual impression trays of hard resin material.

Wherein, described step 5) will be along alveolar ridge surface offsets 2-3mm along alveolar ridge surface normal.

It is an advantage of the current invention that:

There is provided a kind of Dental implantion to repair the designing and manufacturing method of individual tray, by Design of digital and The Dental implantion made is repaired individual tray and is substituted traditional-handwork making, it is achieved clinical oral height is certainly Dynamicization, high accuracy make Dental implantion and repair the target of individual tray, can the most effectively carry High clinical fenestration plantation is repaired individual tray and is designed and produced level, improves diagnosis and treatment efficiency and quality.
