Resin-retained-bridges should be considered when a fixed prosthesis retained by natural teeth is required. [3] The use has been driven by the advent of evidence-based dentistry showing the benefits to patients of reduced tooth preparation and the importance of an intact enamel structure for the long-term health of the teeth.
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.
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.
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.
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 ...
The All-on-4 treatment concept is a prosthodontic procedure (i.e replacement of missing teeth) that provides a permanent, screw-retained, same-day replacement for the entire upper and / or lower set of teeth with a bridge or denture. The procedure is best for patients with significant tooth loss or decay, and for people whose bone loss in the ...
Common indirect restorations include inlays and onlays, crowns, bridges, and veneers. Usually a dental technician fabricates the indirect restoration from records the dentist has provided. The finished restoration is usually bonded permanently with a dental cement. It is often done in two separate visits to the dentist.
