Implant placement: The dental implants, which resemble small screws made of titanium, are surgically placed in the jawbone. In effect, a dental implant replaces the tooth's natural root. Each implant is inserted into the gums and jawbone through a small incision. One of the advantages of implant-supported dentures is that fewer implants can be placed than teeth. For complete upper dentures, between six and eight implants are placed. For complete lower dentures, four to five implants are placed. After the implants have been placed, the gums and bone will take three to six months to grown in around the implant, a process called osseointegration.
George Washington (1732–1799) suffered from problems with his teeth throughout his life, and historians have tracked his experiences in great detail.[14] He lost his first adult tooth when he was twenty-two and had only one left by the time he became president.[15] John Adams says he lost them because he used them to crack Brazil nuts but modern historians suggest the mercury oxide, which he was given to treat illnesses such as smallpox and malaria, probably contributed to the loss. He had several sets of false teeth made, four of them by a dentist named John Greenwood. None of the sets, contrary to popular belief, was made from wood or contained any wood.[16] The set made when he became president was carved from hippopotamus and elephant ivory, held together with gold springs.[17] Prior to these, he had a set made with real human teeth,[18] likely ones he purchased from "several unnamed Negroes, presumably Mount Vernon slaves" in 1784.[19] Washington's dental problems left him in constant pain, for which he took laudanum.[20] This distress may be apparent in many of the portraits painted while he was still in office,[20] including the one still used on the $1 bill.[21][a]
The process of getting dentures requires several appointments, usually over a period of several weeks. Highly accurate impressions (molds) and measurements are taken and used to create your custom denture. Several “try-in” appointments may be necessary to ensure proper shape, color, and fit. At the final appointment, your dentist will precisely adjust and place the completed denture, ensuring a natural and comfortable fit.
Generally speaking partial dentures tend to be held in place by the presence of the remaining natural teeth and complete dentures tend to rely on muscular co-ordination and limited suction to stay in place. The maxilla very commonly has more favorable denture bearing anatomy as the ridge tends to be well formed and there is a larger area on the palate for suction to retain the denture. Conversely, the mandible tends to make lower dentures much less retentive due to the displacing presence of the tongue and the higher rate of resorption, frequently leading to significantly resorbed lower ridges. Disto-lingual regions tend to offer retention even in highly resorbed mandibles, and extension of the flange into these regions tends to produce a more retentive lower denture. An implant supported lower denture is another option for improving retention.
Regardless of the type of dentures you get, it will take some time to get used to them. Don’t be surprised if it takes you a few weeks to get accustomed to the feel of your new dentures. Most people experience some level of discomfort or soreness in the beginning. If you experience pain as well, speak to your dentures dentist about what you can do to minimize the discomfort.
New dentures may feel a little odd or loose for a few weeks until the muscles of the cheeks and tongue learn to keep them in place and you get comfortable inserting and removing them. Also, it is not unusual for minor irritation or soreness to occur and for saliva flow to increase when you first start wearing dentures, but these problems will diminish as the mouth adjusts.
