Teeth function in one of the most inhospitable environments in the body. Many gram-negative and gram-positive bacterial species form a major part of dental plaque around the teeth and also colonize the mucosal surfaces. Moreover, saliva is a hypotonic solution containing bioactonate, chloride, potassium, sodium, nitrogenous compounds, and proteins. Saliva has several viruses, bacteria, yeast and fungi and their products, such as organic acids and enzymes, epithelial cells, food debris, and components from gingival crevicular fluid. Yet, for the most part, oral tissues remain healthy. Oral tissues are exposed to a veritable bombardment of both chemical and physical stimuli as well as metabolism of about 30 species of bacteria (the total salivary bacterial count is said to be five thousand million/ml of saliva). It is also the habitat of microbial species that are kept wet by saliva. The mouth is the portal entry of the human body. An overview of the corrosion aspect of dental implants (titanium and its alloys).

This knowledge will also be helpful in exploring possible research strategies for probing the biological properties of materials. This article highlights a review of the various aspects of corrosion and biocompatibility of dental titanium implants as well as suprastructures. The combination of stress, corrosion, and bacteria contribute to implant failure. The long term presence of corrosion reaction products and ongoing corrosion lead to fractures of the alloy-abutment interface, abutment, or implant body. They are used in dentistry in cast and wrought form. Titanium and its alloys are used in dentistry for implants because of its unique combination of chemical, physical, and biological properties.

When Stafford sees the enormous bird gobbling away on his sideline, he’ll run for the locker-room and never look back. Little does the Lions’ coach know, Matthew Stafford has a debilitating fear of turkeys-meleagrisphobia, it’s a real thing. In honor of the holiday, Patricia will dress up as a turkey. This is a matchup of Belichick minions with Matt Patricia and Romeo Crennel facing off-think we know who has the advantage. Since I’ll be releasing my weekly fantasy football rankings each Thursday morning (except Thanksgiving week!) for the duration of the season, I’ve decided to throw in some bonus bold Thursday Night Football predictions along with my expertly handicapped pick for the contest:įorecast: Thanksgiving wouldn’t be Thanksgiving without a crappy Lions team playing in the morning game and your drunk Uncle Arlo yelling about his all-time favorite Lions player, Whizzer White. After I was arrested for stealing old ladies’ purses from the retirement home down the block to fund my string of Arizona Cardinals’ Super Bowl wagers (a 50:1 lock!), the judge sentenced me to 6 month’s of in-patient rehab. I just snuck out of a court ordered gambling rehab facility to write this post, so I’ll have to be brief.
