This presentation covers some of the most common biomaterials used in plastic surgery. It will cover Silicone , Hydrogels and cellulose in detail along with their properties and uses in the specific domain. # I hope this is useful for you all :)

1. • PLASTIC SURGERY
Cosmetic or aesthetic
surgery
Reconstructive surgery
Craniofacial surgery
Hand surgery
Micro surgery
Treatment of burn

3. 1. Silicone
2. Dacron
3. Cellulose
4. PMMA
5. Polyurethanes
6. Hydrogels
7. Stainless steel
8. Titanium
9. Alumina
10. Hydroxyapatite
11. Collagen

4.  Derivatives of compounds with a polysiloxane base
 Synthetic polymer
 Supplied in the form of fluids,rubbers or resins

5.  High binding energy
 Heat and cold resistance
 Weatherability
 Moisture and steam resistance
 Electrical insulation
 Thermal conductivity
 Transparency and coloring propeties
 Physiologically inert

6. • Reconstructive surgery
 Breast,scrotum,chin,
nose,cheek,calf,
buttocks
 Substitutes of tissues
of all shapes and sizes
 Used to make implants
or devices

7. • BIODURABILITY :
 Strong stability in the body
 PDMS is added to increase the biodurability of other
polymers such as polyurethanes
• BIOCOMPATIBILITY :
 Intrinsically biocompatible due to their chemical stability
 Also due to low surface energy

8. • TOXICOLOGY :
 Are immunologically inert
 Production of antibodies does not occur in the implant
recipient
• DISADVANTAGES OF SILICONE IMPLANTS :
 Capsular contracture
 Pain in the breast, testis
 Infection
 Leakage or rupture of implant

9.  Water swollen polymeric
structures crosslinked together
◦ Cross-links produced through:
 Chemical reaction to form covalent
bonds
 Entanglement of polymers
 Hydrogen bonding and van der Walls
forces

11.  Buttock implant
 Biomaterial, coatings for medical devices,
contact lenses
◦ Biologically compatible
 Drug delivery
◦ Degradable, swelling properties
 Many other biological applications
◦ Develop human tissues

12.  Cellulose (C6H10O5)n is a long-chain polysaccharide
carbohydrate, of beta-glucose.
 It forms the primary structural component of plants
and is not digestible by humans

13.  Density
 Polarity
 Chain branching
 Cross linking
 Chain length

14.  Very much stable in thermal condition
 Shows thermal softening at 231-253 degree
centigrade
 Thermosetting in nature

15.  Low conductivity and high resistivity of electricity
 Relative humidity also affects the electrical
resistivity
Fatigue and Tribological Properties:
 Have good toughness,gloss,clarity ,
processability
 Excellent stiffness,hardness and dielectric
properties

16.  To stop bleeding after facelift
 To prevent cosmetic defects in oncoplastic
breast surgery
