Sirona Cerec Inlab 4.1

The system uses CAM/CAM technology, which means that the whole production of prosthetic work is controlled by computer

Starting optical impression (scanning directly in the mouth with cerec AC unit with bluecam) instead of classical impression, designing anatomically shaped tooth, milling and finishing work.

USED FOR:

Production of ceramics crowns Production of bridges Production of veneers Production of zirconium frameworks

WHY?

perfect fit (24 microns sensitivity) biocompatible material minimize the number of patient visits

- productions crowns and brigdes and laminates in one visit

top quality material absolute accuracy - long lifetime of

work

ANTERIOR BASIC SHAPE CROWN

There we choose shape of crown for example adult,

juvenile, asian…

SPACER Possibility for setting

the space for the fastening material below the restoration-cement.

OCCLUSAL MILLING OFFSET Apply or remove

material in the occlusal

direction over the entire occlusal surface.

PROXIMAL CONTACTS STRENGTH

Set the thickness of the approximal contacts.

OCCLUSAL CONTACTS STRENGTH

Set the thickness of the occlusal contacts.

MINIMAL THICKNESS RADIAL Set the minimum wall thickness in the horizontal direction. The software tries not to fall below this thickness when calculating the restoration suggestions.

MINIMAL THICKNESS OCCLUSAL

Set the minimum wall thickness in the

occlusal direction.

MARGIN THICKNESSReinforce restoration margins with

additional material.– Simplifies handling of the restoration– Prevents splitting of the material

The additional material can be milled off manually before inserting the restoration.

Can be switched on and off

REMOVE UNDERCUTS Undercuts within the preparation margin are

blocked out in the restoration bottom.

FOR MODELING WE USE

APPLY MATERIAL

REMOVING MATERIAL

SMOOTHING

control points of contact

Finished work

now we must choose the material which will be

used for milling finished work

TYPES OF MATERIAL

Esthetic ceramics-luminosilicate glass

Structural ceramicsA)low glass contentB)no glass content-polycrystalline-alumina, zirconia

ceramic block

next step is milling in this device
