Hemos elaborado una pequeña presentación sobre el CAM y el Fresado Dental. En este documento encontrará: Cual es la diferencia entre un sistema de mecanizado dental abierto y cerrado? Cuales son las ventajas e inconvenientes de un sistema abierto y cerrado? Puede abrirse un sistema de fresado dental cerrado? Puede cerrarse un sistema de fresado dental abierto? Este documento cubre algunos de los diferentes aspectos importantes a considerar en la elección y uso de sistemas de fresado Dentales y sus componentes relacionados.

Four components to Dental Milling…
• Scanner – from impression or chair side
• CAD Software – Used on scan data to design final
piece to be machined
• CAM Software – creates the CNC cutterpaths which
drive the CNC milling machine
• Mill – creates the physical components by cutting
material

Closed Systems
Start to finish complete package which
utilizes their own customized hardware
and software.
Examples: Sirona®, Lava®, Kavo® (old
Macintosh computers were closed also)
You are buying a complete system
encompassing all components of
manufacture (scanner, CAD, CAM, mill)

Advantages:
• All the selections have been done for you.
• Purchase and Support from one company.
Disadvantages:

Locked into one process model :
If everyone has the same closed system, then no single
company can have a competitive milling advantage over any
other company, as they all use the same system.
Closed systems do not allow for innovation within the
process, or for companies willing to attempt new or different
methods to implement them. They allow for no competitive
advantage.

End user selects the individual pieces
of the process, based on their
requirements. (scanner, CAD, CAM,
mill)
If they want to cut metal, they can
choose a mill good for metal, if they
only want to cut soft materials, they
may choose a different machine.
Not locked into any particular
process.

Advantages :
• Allow Labs to make the best
selection based on their
individual goals and objectives.
• Allow for continuous innovation
and for labs to create their own
competitive advantages.
• Allow for labs to choose among
several material and tooling
suppliers for cost efficiency.

WorkNC Dental - 2014
A complete or semi-complete bundle of
different open components.
A vendor assembles his favorite open
components into a “turn-key” solution.
Selling a package of scanner, software
and mill, often with Value Added
training and support.
Turn Key Systems

14. Page 14Page 14

Advantages:
• Training, service & support from one vendor
• Simplicity when choosing
• Can provide some bundled cost advantages
Disadvantages:
• Vendor may not be familiar with other or newer/better
open components
• Vendor may not have selected the best open components
for your business needs.

These are systems that were closed, but
are now opened, allowing for the use of
other open components.
Understanding how to work around the
limitations of a closed system utilizing
open components.
Advantages:
• Cheaper materials.
• Better software and programming
options if you have already invested
in a closed system.

Typically found in turn-key applications
This is when a turn key provider of open components utilizes some
methods to limit the manufacturing system.
For example, having a turn key solution and then using a system of serial
numbers to force material/stock purchases from one source, instead of
truly open sourcing.

What to Consider when Purchasing
a Milling System ?
Determine your needs.
• What parts will you be milling?
• What materials will you be milling?
• Will you need multi axis (5 axis)?
• What volume of parts do you plan to manufacture?

20. Page 20Page 20
WorkNC Dental - 2014
Simple copings and bridges may
require less programming and need
less CAD or CAM functionality than
bars or implant bridges.
Ensure you get a software
demonstration on your sample data.
What Parts will you be Milling?

21. Page 21Page 21
WorkNC Dental - 2014
Softer materials like Zircon, wax,
pmma may require less horsepower
and torque for milling than harder
materials such as CrCo and Titanium.
• Cut a sample in the material you
plan to mill.
• In some cases, two slower mills
may cost less than one high-end
mill, yet overall out-produce it.
What Materials will you be Milling?

22. Page 22Page 22
WorkNC Dental - 2014
• 3+1 Axis – can only mill top
and bottom.
• 3+2 Axis – Can mill from any
angle. It rotates into position,
then mills in a 3-axis motion.
• 5-Axis – Can rotate and mill
simultaneously (undercuts).
Will you need Multiaxis - 5-Axis?

• Sizes and Speeds of Mills
vary greatly.
• Costs also vary greatly
Make a realistic assessment of
volume and purchase milling
machines accordingly.
What Volume do you plan?

• Wet Milling: flooding or spraying
with coolant and oils, often
required for certain materials such
as Glass ceramic or Titanium …
• Dry Milling: WAX, Zircon…
• May be difficult to go back and
forth between wet & dry. Will this
be important to you?
Milling – Wet or Dry

• Air Compressor
• Sintering Oven
• Sturdy Table / Mounting location
• Vacuum for dust (Zircon)
• Chip evacuation (metals)
