Multi-unit abutment

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.[5][6][7]
