Technology

All or nothing

he Ceramill Wizard guides the

user through the design process

precisely and efficiently. It is in-

tegrated in the CAD software and helps

both new users as well as experienced

users to move confidently in the pro-

gramme during the design phases.

Model preparation

In the first tool the operator enters all

patient-relevant dynamic data using

the articulator and stores them in the

background (Fig. 1). A left click on the

option “Continue” takes the operator

to the next processing stage.

The tool “Positioning the diagnostic

model” gives the dental technician an

idea of the shape and position of the

anterior teeth, so that the technician

knows how the design of the finished

restoration could look at the end of the

design. Using “three-point alignment”

and “Best fit adaptation” the software

calculates the definite alignment of the

situ scan to the working model. The

subsequent working stages can be

checked and reliably implemented at

any time thanks to this superimposed

cover as diagnostic model over the

working model (Fig. 2 to 3).

The Ceramill Wizard next shows how

the preparation margins can be de-

fined on the individual dies using a

single mouse click. The Wizard then

calculates the margins fully automati-

cally. The dental technician can enter

adjustments at any time (Fig. 4 to 5)

before starting preparation of the

virtual model.

A uniform cement gap can be deter-

mined via the “Gap” tab. The contact

surfaces of the crown margins can also

be defined by the operator, so that it is

immediately visible what the size of

the cement gap will be on the surface

of the die (Fig. 6).

The way to functional and aesthetic anterior restorations, Part 4

All or nothing

Model fabrication, scanning, virtual articulation: this is

the basis for a planned anterior restoration. After entering

the patient data in the CAD software in the third part of the

article series, Master Dental Technician, Dietmar Schaan

and Dental Technician, Knut Miller will now focus on the

step-by-step design of an aesthetically functional resto-

ration.
