MULTI UNIT ABUTMENTS Why most preferred and where it used? A small piece of metal used as a connector to join the dental implant to a dental prosthetic is called Abutment. Multi-unit abutments (MUA) are commonly used in coordination with zygomatic dental implants and full arch replacements. MUA are available in different sizes and angles. 0°, 17°, 30° and 45° are the angles often used for MUA. The different angels offered allow the dentist greater flexibility while placing all-on-four implants.
