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.
Dentures are removable dental appliances that replace missing teeth. Unlike dental implants and dental bridges, which are more or less permanently affixed to the bone, dentures are prosthetic teeth attached to a supporting structure. Dentures can be removed at night, for cleaning, or whenever desired. The most affordable dentures are those made with traditional plastic prosthetic teeth, but even more expensive porcelain cosmetic dentures usually cost less than implants.
He was very good and I did not once feel the needle. Then he extracted the 7 teeth is less than 5 minutes! I was amazed at the skill he used. I had some really bad ones, that a regular dentist would not have touched, but this guy was the best... Once the teeth were out, he put in the temporary denture and had to make a couple small adjustments, because it was too tight. He used a "liquid bandage" substance over the wounds and put the denture in...
To clean your dentures, take them out of your mouth and run clean water over them to dislodge any food particles that may be stuck between teeth, along the gum line, or underneath the structure. Then brush the dentures all over with a denture brush or very soft toothbrush using a mild soap or denture cleaner. Be sure not to use any other cleaners, regular toothpaste, or electric toothbrushes as these are all too abrasive and can damage and wear away the denture materials. After cleaning, make sure to rinse them well.
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.
