Due to their strength, flexibility, and biocompatibility, titanium alloys are often used for joint and bone implants. Chromium and cobalt alloys, as well as stainless steel are also, though somewhat less commonly, used for bone implants for similar reasons.
Shape-memory alloys have biomedical applications in procedures such as angioplasty where they can prevent blood vessels from becoming reblocked.
Ceramics, though they include good chemical and corrosion-resistant properties, are notoriously brittle. Researchers therefore have sought ways of combining desirable ceramics with other materials to tailor properties such as strength and elasticity to meet system requirements. Composites, functionally gradient materials, and coatings have been studied to optimise material choices. Ceramic coated, biocompatible metals seem to offer an excellent compromise between the strength and flexibility of metals and the ability of ceramics to be incorporated into biological systems.

Hi, I think my problem is quite complex. I ve been suffering from hyperhidrosis for 10-12 years now. about 2 years ago I started to use a very strong antiperspitant, based on aluminium- chloride , and it worked quite well till 1 week ago when I d got my contraceptive implant.. Now it s even worse than it s ever been. I don t sweat that much as I used to but when I do just a little bit (what was not a problem before, because the antiperspirant kept me dry-ish and I did not smell) I stink like an onion left on the sun for 2weeks.. Even my smell changed.. It s never been this bad.. Do you think the implant can change your smell? do you think I should take the implant out? Or what do you suggest to do? It s driving me mad!! Thank you

I had an implant placed in June of this year. During my recovery I was taking pain medication but never really experienced pain in the area of the implant, my pain was always in my left arm and still continues. My cardiollogist suspects that physical therapy should resolve this

I take 25 mg of Trazodone to sleep, for I have fibromyalgia. Today I had oral surgery (a dental implant) and was sent home with Percocet, which also makes me sleepy as a side effect, but just for 4 hours or less. If I need the Percocet for the pain, should I skip the Trazodone tonight? Or do they work safely together? (Should I start out with just Trazodone and see if I wake up in pain?) I can t come up with the obvious solution here. I m sorry, I didn t understand that this was a pay service. I feel like an idiot for having given up private medical information to this website -- and for failing to call the pharmacy before it closed, so I m stuck without an answer.
