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.
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.
An alternative to the traditional bridge is the resin-bonded or adhesive bridge (also called a Maryland bridge). A resin-bonded bridge utilises retainer "wings" on the sides of the pontic which attach it to the etched enamel of the abutment teeth. Abutment teeth require minor or no preparation.
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 ...
Resin cements are widely selected for luting non-metallic restorations, resin bonded bridges, ceramic crowns and porcelain veneers. [26] They are available in a different number of shades, viscosities and aesthetic try-in pastes. These cements are also an option for use with ceramic and resin composite inlays and onlays. [26]
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.
