Description
Technical field
This utility model relates to materials processing technology field, particularly to the flexibility of a kind of dental prosthetic material
Fixture.
Background technology
In recent years, the raising day by day of people's oral health consciousness has driven Oral Repair product manufacturing industry quick
Development.Wherein, dentistry computer-aided design/area of computer aided makes (CAD/CAM) system and dental prosthetic
The technological change of material is the most noticeable.First that CAD/CAM is general from French professor Duret in 1971
Read and since method introducing field, oral cavity, it is multiple at inlay, onlay, veneer, complete crown, substrate crown etc.
Mouth mending material design and produce field, obtained further being widely applied.
When using CAM system that the dental prosthetic materials such as pottery, wax stone, resin are cut, it is usually
Use fixture to be directly clamped among on cutter by patty repair materials to be processed, make the dummy of needs.
Therefore, select suitable fixture to realizing the precise positioning of repair materials, effectively reinforce, increase operation rate and
Working (machining) efficiency and saving Oral Repair cost are crucial.
The fixture of dental prosthetic material of the prior art is rigid fixture, as it is shown in figure 1, by fixing
Support plate 1 and detachable hold-down ring 2 form, and qualitative can move frame for movement for certain one.This rigid fixture is at folder
When holding patty repair materials 3, repair materials 3 must have the shoulder 31 of fixed thickness, and usual thickness is
10mm, just can be made repair materials 3 clamping in rigid fixture symmetrical, thus be met not by clamped one time
Stack pile, such as 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm equal thickness
