Mechanical Requirements of Dental Implants

Over time, teeth can be lost for a number of reasons including decay, injury and disease. Dental implants are ideal for those who are uncomfortable with removable dentures or the idea of using adjacent teeth as anchors for a replacement tooth. There are certain physical requirements for dental implants to be successful. A thorough examination from your dentist can determine whether you are a good candidate for the surgery.

  1. Features

    • Dental implants are screws that anchor into the upper and lower jaw to serve as "roots" for replacement teeth. The screws are made of titanium to provide strength and durability. Once the initial implant and screw is inserted, the gum is placed over it for three to six months so it can fuse to the bone.

    The Process

    • After the implant fuses with the bone in a process called osseointegration, a post called the abutment is attached to the screw. The abutment fits over the implant that sticks out through the gum line. This extension post is left for the gum to heal around. Once this is done, a crown with a size, shape and color to match the surrounding teeth is attached to the implanted post.

    Function of Strong Bones

    • Having strong bones is a definite requirement for receiving dental implants. The process involves anchoring implants and screws into the jawbone for a secure, lasting tooth replacement. After implantation, it can take up to six months for the bone to heal around the screw. Once the bone is healed, it must be strong enough to keep the anchor in place to hold the crown. Children are not usually eligible for dental implants because their jawbones are not fully developed.

    Significance of Healthy Gums

    • Healthy gums are another requirement for dental implant surgery. The final product of the surgery includes posts sticking out through your gums for a permanent crown. Gums must be strong enough to heal around the post. For gums to be strong, patients must develop good oral hygiene and commit to going to the dentist regularly.

    Expert Insight

    • As with all types of surgeries, a patient must be in good health to receive dental implants. According to the American Dental Association, "chronic illnesses, such as diabetes or leukemia, may interfere with healing after surgery." Using tobacco also puts patients at greater risk of gum disease, "which can weaken the bone and tissues needed to support the implant." An examination from your dentist is required to determine whether dental implants are right for you.
