CAD in Visual Arts: Key Terms & Definitions for Dental Design

3 steps in digital dentistry to fabricate dental prosthesis

1. scan (acquisition)

   1. in language read by computer

2. CAD

3. CAM

CAD definition

use of a software to aid in the creation, modification, analysis, or optimization of a design

CAD steps

1. select margins around crown from scan

2. select crown

3. edit anatomy and dimensions (improve contacts)

4. design die and models

5. export design as STL file

6. upload STL to CAM machine

CAD design depends on quality of the

scan (want to get good margins, etc.)

two types of software programs for CAD

universal and dentistry

universal vs. dental

universal = not only for dental use (don't follow dental rules)

dental = only for dental use (follows dental rules)

universal CAD main advantage and disadvantage

+ accept complex cases and designs

- takes longer and extra training

universal CAD example

autodesk meshmixer*

dental CAD main advantage and disadvantage

+ faster/ easier to design simples cases

- doesn't accept complex cases/ designs, limited

which software program allows you to input anything, not just a tooth/ denture/ scan?

universal software

which software requires STL files containing tooth/ denture/ scan?

dental software

dental CAD examples (4)

- 3shape dental: wax ups and crowns in this course

- romexis CAD/CAM

- inLab CAD (cerec): use this but limited, no dentures, implant guides, etc.

- excocad

closed vs. open system software programs

closed = accepts and scan from 1 type of scanner + sends to 1 milling unit/ 3D printer

open = accepts scans from all open system scanners + sends to all milling units/ 3D printers

closed system main advantage and disadvantage

advantage = straight forward work flow

disadvantage = limited

open system main advantage and disadvantage

advantage = versatile

disadvantage = complex workflow

why is knowing if your program is an open or closed system important?

because you want to know that all your tech is compatibile

is CEREC an open or a closed system?

closed

is AI in CAD? examples of good AI models in crown design>

yes but depends on the software, good: inLab CAD (cerec)

how long does AI in CAD take to design a crown?

between a few seconds and several hours

is AI in CAD good?

some have shown really good results but some are "underdevelopment"

the CAD software used in MUSOD is ___ and is open/closed system with dental/universal software

3shape software

open system

dental software

**not universal, not closed system
