Lecture 1 Flashcards
1
Q
What does ‘PSI’ stand for?
A
Patient Specific Implants
2
Q
What does ‘CMF’ stand for?
A
Craniomaxillofacial
3
Q
What is the problem with standard implants?
A
- They are non patient specific
- They have fit issues
4
Q
How many OEM polymer manufacturers?
A
> 180 (over 180)
5
Q
How many OEM metal manufacturers?
A
> 130 (over 130)
6
Q
How many additive manufactured implants were manufactured in 2019? What is the esimate of additive manufactured implants for 2027?
A
600,000 in 2019
4 mio in 2027
7
Q
What are the 3 branches of Patient specific impant/medical devices (PSI)?
A
- Custom-made medical device (e.g. surgical plate/guide)
- Patient-matched medical device (e.g. skull impant)
- Adaptable medical devices (e.g. bent plate for jaw surgery)
8
Q
Custom-made medical device
A
- for sole use of a particular individual (single patient)
- made with a written request
- Prescriber (requestee) has a certain responsibility for the design
9
Q
Patient-matched medical device
A
- matched to a patient’s anatomy within a specifc design template
- Then “matched” to patient
- Produced in batch
- Designed and produced unde the responsibility of a manufacturer
10
Q
Adaptable Medical Device
A
- Mass produced
- adapted/shaped at the point of care according to manufacturer instruction
- E.g. bending plates
11
Q
What fienlds are PSIs used for?
A
- Neuro
- CMF
- Trauma
- Plastic surgery
- Orthopedics (on the way)
12
Q
Benefits of PSIs:
A
- Better anatomical fit
- Reduced operating time
- Aesthetic
13
Q
What is the oldest application of PSI?
A
- Skull reconstruction
14
Q
Advantages of Medical Additive Manufacturing (MAM)?
A
- Complex bone replacement implants
- Fast (for small quantities)
15
Q
MAM challanges?
A
- Some materials can’t be modified during operation time so bone must be shaped/cut instead
-integrating 3D printing in remote areas
