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). Because the implant to the right is platform switched, its IAJ is more distinct.
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).
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.
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.
Temporary prosthesis on multi-unit abutments. Temporary prosthetics are essential in implant-supported full-arch restorations. Temporary prosthetics in full arch restoration refer to provisional dental appliances that are used to replace missing teeth during the healing phase after implant surgery. Thes
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 1994, Stryker sold the DB Precision Fin Implant System to a group based in Boston which, at that point in time, had been renamed Bicon Dental Implants or simply Bicon (a name that is a portmanteau of the Latin “bi” – meaning two – and “con” – indicating the simple two-part design of the implant/abutment connection).

Resonance frequency analysis was first suggested as an alternative method of analyzing peri-implant bone in a scientific paper by Meredith N et al in 1996. [4] As stated in the paper’s abstract, in measuring implant stability and osseointegration, “radiographs are of value, but a standardised technique is necessary to ensure repeatability.” [4] The new technique tested involved ...
