• Dental implants are are becoming the tooth replacement of choice in dentistry. They are beginning to replace bridges in Europe and North America. They are titanium “screws” that are inserted into the jawbone in place of an extracted tooth. The operation is fairly easy and takes only about 30 to 60 minutes depending on the number of implants to be placed. The implant is allowed to heal for 3 to 6 months and then the dentist uncovers it and inserts an abutment followed by a crown.
