Abstract
Reacently,the dental implant treatment is able to expect a high prospect. This is more dominant in function and aesthetic than artificial teeth. However, the longer treatment period is often pointed out as a problem. n the anterior region of alveolar arch, the labial cortical plate is thinner than its lingual counterpart. herefore, that is first to remodel or resorb after tooth extraction, disease or trauma, and its extent is greater than the lingual cortical bone. In the posterior regions, that is also similar. e, Japanese as a Mongoloid only have the much thinner labial plate than others like Caucasian. Because of that,the reconstruction of the missing tooth might be difficult thing for us. To solve these problems, the implant placed immediately after extraction is often applied. It is suggested that this method is useful for shortening at the treatment period and reducing alveolar resorption. his time, we show two case reports and clinical statistics of immediate loading of dental implants. All the operations were performed in our clinic from April 2004 to December 2007. Twenty-two patients five males and seventeen females were operated on, and twenty-nine implants were placed. As a result, its survival rate is 96.6%. The results of this limited investigation suggest that the dental implant immediately placed and loaded after extraction is one of the useful treatment methods of prosthetic procedure under the appropriate examination, diagnosis and maintenance.
