evaluation is necessary to determine the success rate of the surgery (Slavkin, 2-4).There are two methods of implantation. The first involves two stages: the surgical stage and restorative stage. In the surgical stage the implants are placed and 4-6 months to allow osseointergration. The implant is then uncovered from gingiva and healing caps are placed for about 3-4 weeks. The implants are now ready for the restorative stage with prosthetic devices such as crown, bridges, or over dentures. The other method involves a single stage that only requires one surgical procedure in which the fixture is inserted immediately at the same appointment the implants are placed. This is new and experimental application of Dental Implants and the success rate is still to be determined. (Gougaloff 1-4).Most of the possible complications associated with implant surgery are not serious. Other than the unlikely situation of a severe infection or fracture of the bone, most problems are easily reversed by medication, surgical intervention or removal of the implant. Sometimes the implant can be placed in the same location, or it can be placed in another location. All surgical procedures have certain risks, although complications are unlikely. Surgery on the lower jaw may incur a risk of damaging the nerve, which controls sensation of the lower lip. If the nerve is damaged, there could be a loss of or change of feeling in the lower lip and chin. This change in feeling might involve tingling, itching, burning, feeling cold, feeling hot, or feeling partially or completely numb. Damage to the nerve is not likely. If it does occur, the feeling will usually return gradually to its normal state within a few weeks to a few months. However, if the nerve it is possible that the resulting numbness could last for years or be permanent. Surgery on the upper jaw could result in nerve damage to the corner of the nose or placement of implants in nasal passages or sin...
