Implant Design Intro
Functions of an Implant
1) load transmission = fracture fixation, dental implant

Designing a Biomaterial

-
eg:PLLA on a load bearing facial fracture plate. PLLA degrades but creates an oxide shell on the inside, preventing the degraded PLLS to be dispersed. So the PLLA builds up, and cause inflammatory reposnse when finally released
Considerations
materials: properties, biological response, processing, cost, reproducability, storage
mechanical: structural requirements, manufacturability, biological response
clinical: surgeon useability, implantibility patient response
Biomaterial = used for the replacement and restoration of tissue/constituent function of a living being that may have deteriorated through disease, aging or trauma
A non-viable material used in a medical device, intended to interact with biological systems
-
-
Biocompatibility = the ability of a material to perform with an appropriate host response in specific applications.

-
Medical Device/Implants = made from one or more biomaterials, which may also contain a biological component
