The ultimate goal of pulp capping or stepwise caries removal is to protect a healthy (or reversibly inflammed) dental pulp, and avoid the need for root canal therapy. When dental caries is removed from a tooth, all or most of the infected and softened enamel and dentin are removed.
After an implant is placed the internal components are covered with either a healing abutment, or a cover screw. A healing abutment passes through the mucosa, and the surrounding mucosa is adapted around it. A cover screw is flush with the surface of the dental implant, and is designed to be completely covered by mucosa. After an integration ...
A multi-unit abutment (MUA) is an abutment most commonly used with dental implants in "All-on-Four" protocols. [1] [2] They are designed for screw-retained group restorations, [3] which are often used in combination with angled dental implants [4] and whole arch replacements, as well as screw fixation of bridges made of zirconium or metal-ceramic group restorations to the implant.
In dentistry, an abutment is a connecting element. [1] This is used in the context of a fixed bridge (the "abutment teeth" referring to the teeth supporting the bridge), partial removable dentures (the "abutment teeth" referring to the teeth supporting the partial) and in implants (used to attach a crown, bridge, or removable denture to the dental implant fixture).
In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown.
This dental radiograph displays two identical 5.0 mm diameter Biomet 3i tapered dental implants placed into the lower right mandible. The healing abutment on the more posterior implant [left] is platform matched (it shares the same 5.0 mm diameter as the implant platform), while the healing abutment on the more anterior implant [right] is platform switched (it possesses a 4.1 mm diameter).
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 part of the bridge which replaces a missing tooth and attaches to the abutments is known as a "pontic".
In implant dentistry, the implant-abutment junction (IAJ) refers to the location of intimate contact between a dental implant and its restorative abutment.. The IAJ is a focus of much attention because its morphology and location tend to affect the amount of bone resorption during the initial period of crestal bone changes immediately following implant placement.
