Replacing Missing Teeth With Dental Implants
How Dental Implants Work
A dental implant is an artificial tooth root that is usually constructed from titanium, a biocompatible material that has been used for decades in hip and knee replacement surgeries. The implant is inserted into the jawbone, and the bone fuses with its rough surface in a process called “osseointegration.” Once the artificial tooth root is anchored into the jawbone, a tooth restoration is attached to the abutment, which is the part of the implant that extends from the top of the gums. Implants can be used to replace one or more teeth:
Single Tooth: In this simple procedure, a single implant is placed at the site of a lost tooth and is affixed with a porcelain crown.
Implant Bridge: A traditional bridge is attached by placing crowns on the healthy teeth on either side of the empty tooth sockets, but an implant bridge uses two or more titanium implants to anchor the restoration in place.
Implant Dentures: In cases where several or all teeth are missing, a few strategically-placed titanium implants can hold a full or partial denture in place. Candidacy for Dental Implants
In general, most people who are healthy enough to undergo a dental procedure such as a filling placement or root canal therapy are good candidates for dental implants. You must have healthy teeth and gums, so any cavities or signs of periodontal disease must be addressed first. Tell your dentist if you have any chronic health conditions or are taking medications. These factors will not necessarily prevent you from receiving implants, but your dentist may need to take certain precautions during the procedure to ensure its success. You also need to have a sufficient amount of dense bone tissue to support an implant. However, if you have suffered bone loss, which is common after tooth loss, a bone grafting procedure can help rebuild the tissues.
The Dental Implant Procedure
PLACING DENTAL IMPLANTS IS A TWO-STEP PROCEDURE:
Implant Placement: This part of the process usually only requires local anesthesia, but your dentist can administer something a bit stronger if you feel anxious. Once you are comfortable, your dentist will create an opening in the gum tissues at the site of the missing tooth and then insert the small titanium rod into the jawbone. Your dentist will then close the gum tissues with a few sutures. The gums will heal in about a week, but you must wait several months for osseointegration of the implant to take place. You may be fitted with a temporary tooth restoration to wear while you are waiting.
Placing Restorations: When your implants are ready for permanent restorations, your dentist will take impressions of your mouth to create replacement teeth that blend well with your natural teeth. You will then return to have your restorations permanently affixed to your implant abutments.
