Usually a metallic screw like object is placed inside jaw bone to support the outside teeth or in some cases it acts as anchorage.
Implants fuse to your jawbone; they provide stable support for artificial teeth. Dentures and bridges mounted to implants won't slip or shift in your mouth — a special benefit when eating and speaking. This secure fit helps the dentures and bridges — as well as individual crowns placed over implants — feel more natural than conventional bridges or dentures. Different types of Implant include Classic – Endosseous, Cortical – Endosseous, Mini Implants – Endosseous
Endosteal implants — These are surgically implanted directly into the jawbone. Once the surrounding gum tissue has healed, a second surgery is needed to connect a post to the original implant. Finally, an artificial tooth (or teeth) is attached to the post-individually, or grouped on a bridge or denture.
Subperiosteal implants — These consist of a metal frame that is fitted onto the jawbone just below the gum tissue. As the gums heal, the frame becomes fixed to the jawbone. Posts, which are attached to the frame, protrude through the gums. As with endosteal implants, artificial teeth are then mounted to the posts.
Classic – Endosseous: Once the implant is placed, it takes 3-6 months for the implant to fuse with the bone (Osteointegration), only after this the final prosthesis can be placed in the mouth. The success rate of such implants is very high.
Cortical – Endosseous: This type of Implants rests on Bi-cortical Bone so immediate loading can be done means prosthesis can be immediately placed.
Mini Implants – Endosseous: In Scenarios where bone thickness is limited or in case of Growing children these type of implants are advocated.
