Dental implants are artificial screws made of titanium or zirconium oxide that connect the jawbone and a dental restoration like a crown or denture. They are also called ‘endosseous’ implants or fixtures. They are an artificial tooth root. Once implanted, the implant integrates with the surrounding bone like part of the body. Dental surgeons perform bone grafting procedures to hold the implant in place for patients who do not have enough surrounding bone structure, or graft bone to help connect implants to the maxillary sinuses on either side of the nose when placing dental implants in the upper jaw.
