Dental implants keep improving. Now even patients who don't have enough bone to anchor them can have them.
Patients who have lost a significant number of teeth may require dentures, or man-made replacement teeth. Dentures are generally custom made for the patients and designed to be removed for cleaning. There are two main types of dentures. A conventional full denture is placed in the mouth only after the oral tissues have healed from the extractions, usually after 6 to 8 weeks. An immediate complete denture is placed into the mouth as soon as the remaining teeth are removed. The advantage of an immediate complete denture is that the patient has “teeth” right away and isn’t without teeth until the tissues have healed. Dental Implants There are three parts to a dental implant. The anchor, or section that sits below the gums, is made of titanium, a strong metal. It screws into and fuses with the underlying bone, providing a secure hold for the artificial tooth. The abutment is the portion of the implant on top of the anchor. It protrudes from the gum line and provides an attachment surface for the tooth. The visible portion of the dental implant is the crown. This part is personally crafted to match the patient’s real teeth. The Problem of Tooth Loss Dental implants help maintain bone stability, but patients with removable dentures don’t have any structures under the gums to stimulate bone development. Over time, removable denture wearers can develop a significant amount of bone loss. That loss changes the structure of the bones and interferes with how the dentures fit. The dentures can be built up to accommodate some bone loss. In fact, the American Association of Oral and Maxillofacial Surgeons recommends replacing removable dentures every 7 to 15 years. Eventually, however, the dentures may fit poorly, interfering with chewing, swallowing and speech. Fixed Dentures: The No Bone Solution™ Thomas Balshi, D.D.S., Prosthodontist with Pi Dental Center in Fort Washington, PA, has come up with a surgical solution for patients with significant bone loss. He calls it the No Bone Solution™. A significant amount of planning is done for each patient. First, a thorough oral exam, impressions and cone beam CT scans are performed to assess the health of the patient and obtain images of the oral structures. Next, the information is fed into a computer. Three-dimensional computer models enable the dentist to determine the safest place for the implants. Then, the files are sent to a robotics lab. A model of the skull is built, enabling the dentist to precisely plan the surgery. Finally, using computer-assisted design and manufacturing techniques, a set of temporary teeth is built, using a machine right in the office. The patient is taken into a surgical suite and the surgeon uses the scans and computer planning to surgically place the implant anchors. The big difference in the No Bone Solution anchors and traditional implants is size. Balshi explains that standard dental implants range from 7 to 18 millimeters in length. The implants used for the No Bone Solution are much longer, ranging from 30 millimeters to 52 millimeters. The longer length enables the dentist to place the anchors into deeper (and stronger) bone, like the cheek bone. Another advantage of the procedure is that patients leave the office that day with a full set of teeth. However, these are temporary. Once the oral tissues heal, the same computer-aided design and manufacturing process is used to make the permanent teeth. Balshi says patients may have some discomfort for one to two weeks after the initial surgery. Once the swelling subsides, the new teeth should feel, work and look just like the natural teeth. The No Bone Solution is usually not covered by dental insurance. The procedure is not recommended for patients who have unstable health problems, blood diseases (like hemophilia), head and neck cancer, or for those who are undergoing chemotherapy or radiation to the face or neck.
