2. Conventional Use
CAD/CAE software are usually used for
engineering purpose like drafting , designing and
analyzing number of engineering parameters.
These techniques have been used in Automobile,
Naval Architecture , structural analysis ,
Aerodynamics , etc.

4. Using CAE DIFFERENTLY!!
• We can offer the support to the medical area by
the engineering.
These computer based software find application
in the following Medical Sections :
a. Dentistry
b. Prosthesis
c. Bio-caE studies
d. Archeological studies

5. Dentistry
STEPS
DIGITAL Impression : Scanning the decayed or broken tooth
using laser beams.
VIRTUAL RESTORATION: Generation of virtual Tooth.
This virtual data is then send to the 3-D printing devices
and the tooth shape is carved on the ceramic material to
produce the artificial tooth.

6. Prosthesis
• Processes like CT SCAN & MRI generate information.
• These information are fed to CAD software , which
prepares a 2-D representation of joint.
• This in turn is fed to Solid Modeling software for generating
a 3-d model.
• CAE software which uses techniques like FEA gives the
detailed views of the strengths and weaknesses of the
different parts.
• This would be useful in applications like surgery,
manufacture of personalized artificial limbs etc.
• Rapid prototyping is the next phase that would be adopted
in the manufacture of the desired joint.

7. BioCAE Studies
• The technique tries to utilize CAD / FEA to detect and
understand the stress points in the knee, hip and the
shoulder joints, and aid in the manufacture of artificial
joints and limbs.
ARCHEOLOGICAL STUDIES
The Dinosaur vocal cord concept from Hollywood
movie Jurassic Park.
AND MANY MORE. . . .

8. SOFTWARES USED
• ISUS, CAD/CAM
• CEREC
• Delcam
• WorkNC Dental
• Renishaw plc

9. FUTURE SCOPE
• CAE/CAD software can be used in space projects to
study the behavior of human body under space
conditions.
• These may also find scope in pro-active study of bones
and joints, and may lead towards generating solution to
certain solutions.
• Rapid prototyping is more accurate than casting &
therefore artificial limbs and joints will be more
accurate in functioning.

11. Abstract: This paper proposes a state of the art manufacturing procedure for
customized artificial limbs and joints.
amazed?? read on. The technique described in this paper tries to utilize the advanced
Computer Aided Design (CAD) /
Finite Element Analysis (FEA) to detect and understand the stress points in the knee, hip
and the shoulder joints, and
aid in the manufacture of artificial joints and limbs. This system takes input and CT scan,
which is then fed into cad by
means of an external reference. What is there now in the cad is a two dimensional
representation of the joint. The next
step is to feed the data into a solid modeling software so that a three dimensional
representation of the joint is obtained.
Once a true representation is obtained computer aided engineering software which uses
techniques like finite element
analysis gives the detailed views of the strengths and weaknesses of the different parts.
The output of this would be
useful in applications like surgery, manufacture of personalized artificial limbs etc. rapid
prototyping is the next phase
that would be adopted in the manufacture of the desired joint.
