A Solution of Choice for Replacing Missing Teeth
Statistics show that 69% of adults ages 35 to 44 have lost at least one permanent tooth to an accident, gum disease, a failed root canal or tooth decay. Furthermore, by age 74, 26% of adults have lost all of their permanent teeth. Twenty years ago, these patients would have had no alternative but to employ a fixed bridge or removable denture to restore their ability to eat, speak clearly and smile. Fixed bridges and removable dentures, however, are not the perfect solution and often bring with them a number of other problems. Removable dentures may slip or cause embarrassing clicking sounds while eating or speaking. Of even greater concern, fixed bridges often affect adjacent healthy teeth, and removable dentures may lead to bone loss in the area where the tooth or teeth are missing. Recurrent decay, periodontal (gum) disease and other factors often doom fixed bridgework to early failure. For these reasons, fixed bridges and removable dentures usually need to be replaced every seven to 15 years.

Today there is another option for patients who are missing permanent teeth. Rather than resting on the gum line like removable dentures, or using adjacent teeth as anchors like fixed bridges, dental implants are long-term replacements that your oral and maxillofacial surgeon surgically places in the jawbone. Composed of titanium metal that “fuses” with the jawbone through a process called “osseointegration,” dental implants never slip or make embarrassing noises that advertise the fact that you have “false teeth,” and never decay like teeth anchoring fixed bridges. Because dental implants fuse with the jawbone, bone loss is generally not a problem. After more than 20 years of service, the vast majority of dental implants first placed by oral and maxillofacial surgeons in the United States continue to still function at peak performance. More importantly, the recipients of those early dental implants are still satisfied they made the right choice. If properly cared for, dental implants can last a lifetime.
Advantages of Implant Dentistry
Dental implants are stronger and more durable than their restorative counterparts (bridges and dentures). Implants offer a permanent solution to tooth loss. Additionally, implants may be used in conjunction with other restorative procedures for maximum effectiveness. For example, a single implant can serve to support a crown replacing a single missing tooth. Implants can also be used to support a dental bridge for the replacement of multiple missing teeth, and can be used with dentures to increase stability and reduce gum tissue irritation. Procedural advancements, including the development of narrower “mini” implants, mean that more people than ever before are finding themselves candidates for implantation. However, candidacy for implantation still varies, meaning that your dentist may determine that you should opt for an alternative restoration. Keep in mind, too, that dentists do not need a specific license by law in order to perform implant dentistry. A general or restorative dentist may perform the crown and bridge placement that is associated with implant restoration.
Anatomy of a Dental Implant
A dental implant designed to replace a single tooth is composed of three parts: the titanium implant that fuses with the jawbone; the abutment, which fits over the portion of the implant that protrudes from the gum line; and the crown, which is created by a prosthodontist or restorative dentist and fitted onto the abutment for a natural appearance. Many people who are missing a single tooth opt for a fixed bridge; but a bridge may require the cutting down of healthy, adjacent teeth that may or may not need to be restored in the future. Then there is the additional cost of possibly having to replace the bridge once, twice or more over the course of a lifetime. Similarly, a removable partial denture may contribute to the loss of adjacent teeth. Studies show that within five to seven years there is a failure rate of up to 30% in teeth located next to a fixed bridge or removable partial denture.
Fixed bridges may require the shaping or cutting down of adjacent healthy teeth. Bone is maintained by the presence of natural teeth or implants (a). Bone loss occurs with the loss of teeth (b). Bone is maintained by the presence of natural teeth or implants (a). Bone loss occurs with the loss of teeth (b). Further, conventional dentures may contribute to the loss of bone in the area where teeth are missing. As illustration (a) indicates, the presence of natural teeth preserves the jawbone. When a tooth is missing, as in illustration (b), the bone may erode and weaken until it may be necessary for your oral and maxillofacial surgeon to graft bone to the area to strengthen it for placement of a dental implant. When a missing tooth is replaced by a dental implant, the fusion, or osseointegration, of the implant and bone provides stability, just as the natural tooth did. If you are missing several teeth in the same area of your mouth, you may still enjoy the confidence and lifestyle benefits that come with dental implants. Your oral and maxillofacial surgeon will place two or more dental implants, depending on the number of teeth that are missing. Your replacement teeth will be attached to the implants to allow excellent function and prevent bone loss. The implants will serve as a stable support that tightly locks into your replacement teeth and dentures to prevent slipping and bone loss. With an overall success rate of about 95% and almost 50 years of clinical research to back them up, dental implants are frequently the best treatment option for replacing missing teeth.
