11Materials forBiomedicalApplications
Biomaterials: Material intended to interface with biological systems to evaluate, treat, augment, or replace any tissue, organ, or function of the bodycf) Biological Materials
Biocompatibility 1. composition of biomaterials2. fabrication process3. implant production
1.1.2 History and Current Status of the Field
Plastics [poly(methylmethacrylate)] to Metal, Ceramic, Polymer
1. mass production and sterilization 2. physical, chemical, mechanical, and degradative properties 3. no tissue interaction 4. low healing 5. low chance of human application
1.5 Processing of Biomaterials
(1) surface modification to alter the surface chemical and physicalproperties
(2) shape
1.6 Important Properties of Biomaterials
1.6.1 Degradative properties
undesirable for implantation desirable for certain materials (biodegradable materials)
1.6.2 Surface properties
chemical and physical properties
1.6.3 Bulk properties
(1) mechanical properties : strength and stiffnessanisotropyfatigue property
