Dental implants are a remarkable advancement in dental research. They resemble natural teeth, are extremely sturdy, require the same maintenance as natural teeth and often can last a person's lifetime. Dental implants are defined as "permanent fixtures of titanium posts anchored to the jawbone and topped with individual replacement teeth or a bridge that screws or cements into the post." Dental implants got their start in Sweden but the technology and materials that are being used in North America today have been successfully used in European countries for the past thirty years.
The success rate for both upper and lower implants is extremely high. For instance, lower implants have the highest success rate at 98 percent while for upper implants it is 91 percent. However there are some adverse effects that are associated with dental implants although the good news is that there is not that many. Let's take a look at some of them.
Sometimes dental implant surgery fails because of bacterial contamination that is to be found at the site of the implants. If the area is not adequately cleaned beforehand then this is likely to occur. In order to decrease the chance of infection occurring following the surgery, patients are often prescribed one or a variety of prophylactic systemic antibiotics. The use of antibiotics in some individuals can cause its share of adverse effects ranging from diarrhea and vomiting to more serious allergic reactions that require immediate medical attention. With the use of antibiotics comes a concern about bacteria that is antibiotic-resistant. Tests are ongoing to determine to what extent antibiotics are necessary where dental implant surgery is concerned. This issue is somewhat of a controversial one as some patients seem to benefit from the use of antibiotics after surgery while others find it a hindrance to healing and ushers in a host of other adverse side effects. Some researchers believe that prophylactic antibiotics are very effective in reducing the incidence of dental implant failures while others are still not sure. New research into these health issues is being undertaken all of the time.
