Biomaterials

  1. 1. Define Biomaterial Science Characterist ic Important Factors Classificatio n Applications
  2. 2. A biomaterial is any substance that has been engineered to interact with biological systems for a medical purpose - either a therapeutic (treat, augment, repair or replace a tissue function of the body) or a diagnostic one.
  3. 3. Study Of Biomaterials Biomaterials Engineering Biomaterials Science
  4. 4. Biomaterials Science
  5. 5. Bio Material Science Pacemakers Dental Implants Artificial Joints Contact Lenses
  6. 6. Hard Materials. Flexible Material  Must not react with any tissue in the body.  Must be non-toxic to the body.
  7. 7. Bio functionality • Effect of environment on the material • Material must satisfy its design purpose Bio compatibility • Effect of prosthetic device material on the body • Cost and rate of production should also be considered
  8. 8. Classification Synthetic biomaterial Natural biomaterial
  9. 9. Biomaterial which are naturally available are called as natural biomaterial.
  10. 10. Proteins Gelatin Alginate Silk Fibrin Cellulose Chitin Chitosan
  11. 11. Synthetic Biomaterial Polymer Ceramics Metal & Alloys
  12. 12. Applications Heart Valve Artificial Tissue Dental Implants Intraocular Lenses Vascular Grafts Hip Replacements
  13. 13. Heart valves
  14. 14. Artificial tissue • Biodegradable • Polymer Result of Condensation of Lactic Acid and Glycolic Acid
  15. 15. Vascular Grafts • Must Be Flexible. • Designed With Open Porous Structure. • Often Recognized By Body As Foreign.
  16. 16. Hip- Replacements • Some hip replacements ambulatory function restored within days after surgery. • Others require an extensive healing period for attachment between bone and the implant. • Most cases good function restored. • After 10-15 years, implant loosens requiring another operation
  17. 17. Intraocular Lenses • Made of PMM, silicone elastomer, and other materials. • By age 75 more than 50% of population suffers from cataracts. • 1.4 million implantations in the United States yearly. • Good vision is generally restored almost immediately after lens is inserted.
  18. 18. • Capable of bonding to bone, a phenomenon known as "osseointegration”. • Bio-inert, there is no reaction in tissue and no rejection or allergic reactions.
