Retention is the principle that describes how well the denture is prevented from moving vertically in the opposite direction of insertion. The better the topographical mimicry of the intaglio (interior) surface of the denture base to the surface of the underlying mucosa, the better the retention will be (in removable partial dentures, the clasps are a major provider of retention), as surface tension, suction and friction will aid in keeping the denture base from breaking intimate contact with the mucosal surface. It is important to note that the most critical element in the retentive design of a maxillary complete denture is a complete and total border seal (complete peripheral seal) in order to achieve 'suction'. The border seal is composed of the edges of the anterior and lateral aspects and the posterior palatal seal. The posterior palatal seal design is accomplished by covering the entire hard palate and extending not beyond the soft palate and ending 1–2 mm from the vibrating line.
Temporary or interim appliances serve many useful purposes and are often an integral part of a prosthetic treatment plan. These appliances can be designed to be either fixed or removable. This simple appliance is excellent for temporary replacement of front teeth while the patient is waiting for a permanent bridge, a partial, or implants. This removable interim bridge is made of a clear vacuum-formed material. The appliance simply snaps into place.
Dentures that fit well during the first few years after creation will not necessarily fit well for the rest of the wearer's lifetime. This is because the bone and mucosa of the mouth are living tissues, which are dynamic over decades. Bone remodeling never stops in living bone. Edentulous jaw ridges tend to resorb progressively over the years, especially the alveolar ridge of the lower jaw. Mucosa reacts to being chronically rubbed by the dentures. Poorly fitting dentures hasten both of those processes compared to the rates with well-fitting dentures. Poor fitting dentures may also lead to the development of conditions such as epulis fissuratum. In addition, the occlusion (chewing surfaces of the teeth) tends to wear away over time, which reduces chewing efficacy and decreases the vertical dimension of occlusion, (the "open-ness" of the jaws and mouth).
67K hospital bill later ( 2 yrs later now over 80K in medical,they could install her dentures for 15 months , (blood clots got her so weak and run down , nothing would heal, implants finally were strong enough at 16 months , they said, and installed them , but she hadn't eaten solid food for 15 months, now so weak and thin the implants don't fit, they want another few hundred to adjust them, 22months later and still don't fit,she now is anorexic going 2 yrs withouut eating lost almost 40 # is down to 80+ , PS no insurance self pay up front,so because of a tooth ache 100K gone
Implants: An implant is a metal post that is inserted into the bone of the upper or lower jaw. This post is then used to replace a single tooth by attaching a crown to it, or multiple teeth by attaching a bridge to multiple implants. Implants are the most expensive option for tooth replacement, but implants simulate natural teeth better than any of the other options.
If you have ever wondered, “What are partial dentures?” you most likely have a need they can fulfill. The partial lack of teeth, also known as edentulism affects the majority of American adults. We can provide you with partial dentures or complete dentures to restore a smile to full functionality. Complete dentures are for patients who are missing all their teeth. Dentures are also a great option for many people.
Bridges: A bridge replaces missing teeth by placing crowns on the teeth next to the space and attaching a fake tooth to both of the crowns. Bridges are made from gold, porcelain fused to gold, all porcelain, or zirconium. Bridges can only replace about two to three missing teeth in a row, depending on the location. Since bridges are cemented in place, they are considered a "fixed, or permanent denture."
Teeth can fall out for a number of reasons, ranging from genetics to drug abuse. Most commonly, teeth are removed or fall out on their own due to severe tooth decay. Neglect to upkeep oral hygiene or not seeking proper treatment for damaged teeth, can lead to the onset of decay which in turn leads to loss of teeth. Visiting you dentist in 6 month intervals is a good preventive measure to spot any early signs of decay.
