Rochette Bridge
A Rochette bridge is a type of dental prosthesis popular in the 1970s, and described by Alain Rochette in 1973Rochette A: Attachment of a splint to enamel of lower anterior teeth. J Prosthet Dent 30:418. 1973. as a form of resin retained bridge A resin-retained bridge (also known as resin-bonded-bridge or resin-bonded fixed dental prosthesis (RBFDP)) is a bridge (a fixed dental prosthesis) replacing a missing tooth that relies for its retention on a composite resin cement. It is one of m ... that relied on countersunk holes perforating the metal abutment wing. These would be filled with composite cement on seating the restoration, providing macromechanical retention for the prosthesis. This type of bridge fell out of fashion as modern cements and treatments of the retainer intaglio enabled better retention without the loss of strength inherent in perforation of the retainer wing. Nonetheless, some Rochette bridges remain in service even today. References {{DEFAULTSORT:Roch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Prosthesis
A dental prosthesis is an intraoral (inside the mouth) prosthesis used to restore (reconstruct) intraoral defects such as missing teeth, missing parts of teeth, and missing soft or hard structures of the jaw and palate. Prosthodontics is the dental specialty that focuses on dental prostheses. Such prostheses are used to rehabilitate mastication (chewing), improve aesthetics, and aid speech. A dental prosthesis may be held in place by connecting to teeth or dental implants, by suction, or by being held passively by surrounding muscles. Like other types of prostheses, they can either be fixed permanently or removable; fixed prosthodontics and removable dentures are made in many variations. Permanently fixed dental prostheses use dental adhesive or screws, to attach to teeth or dental implants. Removal prostheses may use friction against parallel hard surfaces and undercuts of adjacent teeth or dental implants, suction using the mucous retention (with or without aid from denture adhes ...

Resin Retained Bridge
A resin-retained bridge (also known as resin-bonded-bridge or resin-bonded fixed dental prosthesis (RBFDP)) is a bridge (a fixed dental prosthesis) replacing a missing tooth that relies for its retention on a composite resin cement. It is one of many available dental restoration methods which is considered minimally invasive and conservative of tooth tissue. The resin-retained-bridge has gone through a number of iterations. Perhaps the best known is the Maryland bridge and other designs used in the past include the Rochette bridge. The five-year survival rate is around 83.6% and the ten-year rate at 64.9%. The case selection is important and as with any dental prosthesis, good oral hygiene is paramount for success. In recent years, the indications for the use of resin-retained-bridges have diminished significantly and there have been changes in the principles underpinning their design. Resin-retained-bridges should be considered when a fixed prosthesis retained by natural teeth is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dentures
Dentures (also known as false teeth) are prosthetic devices constructed to replace missing teeth, and are supported by the surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable (removable partial denture or complete denture). However, there are many denture designs, some which rely on bonding or clasping onto teeth or dental implants (fixed prosthodontics). There are two main categories of dentures, the distinction being whether they are used to replace missing teeth on the mandibular arch or on the maxillary arch. Medical uses Dentures do not feel like real teeth, nor do they function like real teeth. Dentures can help people through: * Mastication or chewing ability is improved by replacing edentulous areas with denture teeth. * Aesthetics, because the presence of teeth gives a natural appearance to the face, and wearing a denture to replace missing teeth provides support for the lips and cheeks and corrects the collapsed appearance that ...

Prosthodontology
Prosthodontics, also known as dental prosthetics or prosthetic dentistry, is the area of dentistry that focuses on dental prostheses. It is one of 12 dental specialties recognized by the American Dental Association (ADA), Royal College of Surgeons of England, Royal College of Surgeons of Edinburgh, Royal College of Surgeons of Ireland, Royal College of Surgeons of Glasgow, Royal College of Dentists of Canada, and Royal Australasian College of Dental Surgeons. The ADA defines it as "the dental specialty pertaining to the diagnosis, treatment planning, rehabilitation and maintenance of the oral function, comfort, appearance and health of patients with clinical conditions associated with missing or deficient teeth or oral and maxillofacial tissues using biocompatible substitutes." History Dental prostheory was pioneered by French surgeon Pierre Fauchard during the late 17th and early 18th century. Despite the limitations of the primitive surgical instruments, Fauchard discovered m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
