In some cases, a ‘Maryland’ bridge, a fixed bridge that does not need crowns, is glued onto the back of the teeth adjacent to the space so that minimal tooth structure is removed. Complete dentures or ‘plates’ are the traditional solution for people who have lost all their teeth in one or both jaws. The success of a complete denture depends upon the individual’s jaw size and shape, his or her oral habits, and his or her adaptability. Some people adapt well to dentures, while others are not able to adapt.

Are Dental ImplantsAn Option For Me?If you are considering dental implants, your mouthwill be examined thoroughly and your dental andmedical history will be reviewed to ensure that dentalimplants are appropriate for you. Dental x-rays and,frequently, panoramic (or complete) x-rays of yourjaws will be taken to evaluate your jawbone and todetermine if it will accommodate implants. Occasion-ally, more detailed information is required and can beprovided by special x-rays. They will help determineif additional tests or procedures are needed to placeyour implants properly. taken. Frequently panoramic x-rays of your jaw are taken. What Is A Dental Implant? The best way to describe a dental im- plant is to compare it to a real tooth. A natural tooth consists of a root and a crown. The part of the tooth that you see and eat with is called the crown. Beneath the crown is the root, which anchors the tooth through the gum tissue to the jawbone. When you lose a tooth, you lose both the root and the crown. To replace a tooth, we first have to replace the root. Essentially, a dental implant is a new root. This titanium root is fitted into a socket that we create in your jaw, replacing the lost root of your natural tooth. Dental implants come in various shapes and sizes and have different types of surfaces. The actual implant selection will depend on a variety of factors related to your specific treatment needs and the most appropriate one(s) will be used. Once an implant has been placed in the jaw, the bone around the implant will need to heal for up to six months, depending upon how hard the bone is. When this initial phase of healing is completed, a sup- port post called an abutment will be placed on the im-A thorough examination of your mouth is required. plant itself and then a new crown will be placed on top. If all of your teeth are missing, a variety of treatment options are available to support the replacement teeth.
How Are DentalImplants Placed?Usually, the office procedure to place a dental implanttakes about an hour for one implant and no morethan two or three hours for multiple implants. Theplacement process consists of the following steps:• If indicated, you will be given medication suchas antibiotics prior to the surgery. You may be offeredsedation with nitrous oxide (“laughing gas”) or intra-venous medications. Then, a local anesthetic will beadministered to numb the areas where the implant(s)will be placed.• After you are comfortable, a small incision ismade into the gum tissue, revealing the bone intowhich the implant will be placed.• Using special instruments, a socket is createdcarefully, avoiding damage to the bone.• The titanium implant is then inserted intothe socket.• Finally, if necessary, sutures will be used. Once the implant is inserted, it is completed inone of two ways: First, the gum tissue will be closed(or sutured) over the implant, allowing the implantto heal for up to six months. Then a second procedure,called “uncovering surgery,” will be performed aftera local anesthetic has been used to numb the gumtissue. Next, the gum is moved out of the way, theimplant located, and a healing cap placed into it. Thegum tissue is then sutured around the healing cap.Generally, after two to four weeks, you will return tohave the healing cap removed, the abutment (or sup-port post) placed, and impressions made in order forthe final crown (replacement tooth) to be fabricated.This is called a “two-stage” or “two-step” approachto implant placement and is the more traditional After you lose a tooth, we generally allow theapproach.

During this time, you will befitted with temporary teeth. Occasionally, impressionsare made at the time the implant is placed in order tohave a crown ready when the implants have healed. After the implant is placed, the area will need toheal for as long as six months. How long your mouthwill need to heal will be determined by a variety offactors. Follow-up care (one to four appointments)is usually needed to ensure that your mouth is healingwell and to determine when you are ready for the re-storative phase of your treatment.
When Are The Implants Placed? Approximately three months after the tooth is re- moved, the implant is placed where the missing tooth was located. Once a tooth is removed, if your socket walls of bone are intact and fairly thick, your body will grow new bone to replace or refill the empty socket. Your socket will usually be completely filled in with bone by the time you are ready for placement of your implant (about three monthsHealing cap in place. later). Occasionally, it is possible to take out the tooth and place the implant at the same time. This may in- An alternative approach is called the “single- volve a little more risk, but it simplifies the process—stage” or “one-step approach,” in which a healing cap you won’t have to wait three months for the bone tois added at the same time as the implant is placed refill the socket.

Do I Have Enough Bone?Again, if after tooth extraction the walls of the socketare very thick, they will usually fill with bone in threemonths. However, if the walls of your socket are verythin (such as in your upper and lower front teeth),then this type of healing will not be as predictable. Af-ter waiting three months for the bone to fill in, youmay have only a very thin ridge of bone. Sometimes, abone graft is placed at the time of tooth extraction tohelp your body fill in the socket with bone. This stepwill maintain the width or volume of bone you willneed for implant placement. It is most commonly per-formed on thin-walled extraction sockets, especiallyin such visible areas as the front of the mouth. If your tooth was removed many years ago, thenyour bony ridge may be extremely thin and you maynot have enough bone left for implant placement. Inthis case, a bone graft can be placed next to the thinbone and allowed to heal for three to nine months.After the graft has fused to your pre-existing bone,the ridge will be re-entered and the implant placed.Usually bone grafting is a relatively comfortableprocedure.

Your denture still willthere is evidence of excessive biting force. be removable for easy cleaning and maintenance. A third option involves placing five or more im- plants in your jaw and attaching a permanent denture. Your denture is held in place by screws or clasps that secure it to the support posts or bar. It doesn’t touch the gum tissue, which allows you to clean under the denture without removing it. This denture will replace all your missing lower teeth and will not be removed except at maintenance visits. Although cleaning under your denture without removing it is more time con- suming and requires more dexterity, many patients who want a permanent denture prefer this option. The final option is to have all your teeth individu- ally replaced so that they will appear to be growing out of your gum tissue and will most closely resemble3 Implants Replace 2 Lower Molars.What If I’m Missing All OfThe Teeth In My Lower Jaw?If you are missing all of the teeth in your lower jaw,you may consider a number of treatment options.Although many patients have no problem wearingan upper denture, some find it difficult to wear lowerdentures. The first option is to have two implants placedin your lower jaw and a denture made that snaps ontothese implants.

Although it is natural to be concerned about the pain that may be caused by these procedures, most patients do not experience severe or significant postoperative pain. Pain medication and antibiotics will be prescribed for you to make your recovery as easy as possible. Occasionally, some people develop postoperative infections that require additional anti- biotic treatment. In addition, there is a chance that the nerve in the lower jaw, which provides sensation to your lower lip and chin, may be affected. If you are missing quite a lot of bone, it might be difficult to place an implant without infringing on the nerveImplant Supported Upper Denture. space.

Before treatment begins, every effort will be made to give you an accurate estimate of all the expenses in- volved in placing and restoring your dental implants. This includes the implant placement itself plus any bone and soft tissue grafting procedures that are needed. In many cases, there is an initial charge for the diagnostic work-up, including study models, x-rays, and the fabrication of a surgical template to ensure the best possible result. You also will be charged for the abutment or support post(s), plus the crown, dentures, or anything else that will be placed over the implants, including temporary restorations, as well as for periodic maintenance such as hygiene visits, tissueA variety of toothbrushes and floss are availableto help you clean your implants. conditioners, denture relines and other repairs.
