implant abutment materials

Hi there, I have a presentation to make on “Implant Abutment Materials”, I will be doing the powerpoint myself with ilustrations but all that I need is someone to do a research and gather some information put it together neat and a conclusion. Id say about 3 pages would do. With the main or most comon materials used, why they are used and when, positives and negatives of them, and what causes them to succeed and fail and why.

Just put some notes of all these together since it will not be accessed but I will only be using it to guide my presentation. thank you
