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.
Research has reflected a survival rate of 80% over a period of 6 years or longer, [88] and that cantilever resin-bonded bridges are at least as good as conventional fixed-fixed bridges. Restoring teeth with this method can only be done after orthodontic treatment and will need an element of retention to ensure that tooth contacts are not misplaced.
Post crowns have been shown in some studies to have a higher failure rate. [3] For resin bonded bridges abutment teeth should ideally be unrestored and have enough enamel to support the metal wing retainer. Additionally there must be sufficient space to accommodate the minimum connector width of 0.7mm and 2mm connector height.
A bridge is used to span, or bridge, an edentulous area (space where teeth are missing), usually by connecting to fixed restorations on adjacent teeth. The teeth used to support the bridge are called abutments. A bridge may also refer to a single-piece multiple-unit fixed partial denture (numerous single-unit crowns either cast or fused together).
The acid-etched resin bonded splint is a relatively new alternative method to protect teeth from further injury by more stabilising them in a favourable occlusal relationship. The main goal in this technique is to replace the missing teeth and provided maximum conservation for the structure of remaining teeth.
Fixed bridges cannot be taken out in the same way that partial dentures can. In areas of the mouth that are under less stress, such as the front teeth, a cantilever bridge may be used. Cantilever bridges or Maryland Bridges are used to replace anterior or front missing teeth, are minimally invasive but do have a reputation for failure. [14 ...
Alterations to the teeth, from tooth wear or tooth loss, can lead to a decreased facial height due to physiological compensation that allows for maintenance of upper and lower teeth contact. [6] The Dahl appliance can increase the height of a patient's face and correct for this loss of facial height.
They are commonly used to definitively cement indirect restorations, especially resin bonded bridges and ceramic or indirect composite restorations, to the tooth tissue. They are usually used in conjunction with a bonding agent as they have no ability to bond to the tooth, although there are some products that can be applied directly to the ...
