An instructional material.

2. What is Biomaterial ?
• A biological or synthetic substance which can be
introduced into body tissue as part of an implanted
medical device(as an artificial joint) or used to replace an
organ, bodily function, etc.
• They serve as mechanical scaffolds or supporting
structures for growing cells and tissues

3. TYPES OF BIOMATERIAL
*Natural Biomaterials
*Synthetic Biomaterials

4. NATURAL BIOMATERIAL
• Biomaterials which are naturally available are called as
Natural biomaterials
• These are biocompatibility, biodegradability and
remodeling. Therefore, these biomaterials are usually
applied in the repair or replacement of damaged human
tissues and organs.

5. Examples of Natural Biomaterials
• Gelatin
• Silk
• Fibrin
• Cellulose
• Chitin
• Chitosan

6. SYNTHETIC BIOMATERIAL
• Biomaterials which are produced in a lab or in a industry
with human efforts are called as Synthetic Biomaterial.

7. TYPES OF SYNTHETIC MATERIAL
• Metals and Alloys
• Polymers
• Ceramic
• Composite

8. Metals and Alloys
3 metals commonly used as biomaterials are:
1. Stainless steel
2. Cobalt-chromium-molybdenum
3. Titanium (Ti) or Ti alloys

9. Metal and Alloys Application
• Bone and Joint Replacement
• Dental Implants
• Cardiovascular devices
• External Prostheses
• Surgical instruments
