Single-tooth implants is for individuals with one or more missing teeth. An implant is surgically placed in an opening that your dentist makes from the jawbone. A crown which looks similar to a natural tooth is attached to the implant and fills the space from the mouth by overlooking tooth.However, the process can be accomplished only if there is sufficient bone from the jaw. The bone should be strong enough to hold and support the implant. When there is no adequate bone, then it can be added through bone augmentation or bone grafting process. It's attached to the implant with a screw. The component links the implant into the crown. It's shaped to look like a natural tooth.The restoration is a crown molding. It's made of porcelain fused into a metal alloy. It may also be metal or porcelain. The crown is cemented onto the abutment. If the crown is screwed to the abutment, the screw hole will be covered with restorative material such as tooth-colored filling material.
