1 Sirona Cerec Inlab 4.1

2  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.

3 USED FOR:  Production of ceramics crowns  Production of bridges  Production of veneers  Production of zirconium frameworks

4 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

5 individual part of my work

6 the 3D impression of work for the upper jaw

7 the lower jaw

8 selection of teeth and the type of job

9 bite registration

10 finished bite registration

11 determination of occlusal plane

12 trimming of stubs

13 draw margin -we can use manual or auto

14 draw margin

15 rotation model  for determination of correct axis of the tooth

16 right

17 wrong -because there are many undercuts-red color

18 setting parameters

19 ANTERIOR BASIC SHAPE CROWN There we choose shape of crown for example adult, juvenile, asian…

20 SPACER Possibility for setting the space for the fastening material below the restoration-cement.

21 OCCLUSAL MILLING OFFSET Apply or remove material in the occlusal direction over the entire occlusal surface.

22 PROXIMAL CONTACTS STRENGTH Set the thickness of the approximal contacts.

23 OCCLUSAL CONTACTS STRENGTH Set the thickness of the occlusal contacts.

24 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.

25

26 MINIMAL THICKNESS OCCLUSAL Set the minimum wall thickness in the occlusal direction.

27 MARGIN THICKNESS Reinforce 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

28

29 REMOVE UNDERCUTS Undercuts within the preparation margin are blocked out in the restoration bottom.

30 after setting the parameters followed by automatic selection of teeth shape

31 design

32 FOR MODELING WE USE

33 APPLY MATERIAL

34 REMOVING MATERIAL

35 SMOOTHING

36

37 control points of contact

38 Finished work

39 now we must choose the material which will be used for milling finished work

40 TYPES OF MATERIAL  Esthetic ceramics-luminosilicate glass  Structural ceramics A)low glass content B)no glass content -polycrystalline-alumina, zirconia

41 ceramic block

42 next step is milling in this device

43 milling

44 finished work for example veener and zirconium framework

45 FINISHED WORK IN MOUTH
