REASONS PATIENTS CHOOSE DENTAL IMPLANTS OVER REMOVABLE DENTAL PROSTHESES
As chewing stimulates the root, the tooth's root stimulates the bone and remineralization occurs. Remineralization ensures that the bone is continually replacing the minerals that are naturally lost.
Once a tooth is extracted, the root is no longer present to stimulate the bone; therefore, the body begins to reabsorb it. In the first year following a tooth extraction, approximately 25 percent of the bone is resorbed. This bone resorption can lead to significant changes in the structure of the face. Since traditional removable dentures sit on top of the gum, these dental appliances are unable to stimulate the jawbone the way that dental implants can. Lack of stimulation and bone resorption cause the bone to soften, and deteriorate. Patients with this problem can either have a bone graft performed or choose subperiosteal implants instead of endosteal implants.
SUBPERIOSTEAL IMPLANTS AND ENDOSTEAL IMPLANTS: WHAT IS THE DIFFERENCE?
The endosteal dental implants are the most common type of implant used. They usually consist of titanium, are shaped like a screw and are inserted into the jawbone. Although subperiosteal dental implants are placed beneath the gum, they rest on or above the jawbone. These implants are frequently used for patients who have an inadequate amount of bone and still want implants, but do not want to have a bone graft performed.
WHAT ARE MINI DENTAL IMPLANTS?
Some patients may be candidates for mini implants. These implants are perfect for replacing smaller teeth in areas where a full-sized prosthetic tooth will not fit. The mini dental implant rods are about the width of a standard toothpick and the mini implants are about half the width of traditional dental implants.
