Astra®-compatible Aqua 3.5/4.0mm Straight Multi-Unit Abutment X 3.5mm

Multi-Unit Abutments are screw-retained abutments intended for the retention of cast or milled bar overdentures. For implant-supported prostheses, six or more implants are recommended in the maxilla, four or more in the mandible. If clinical conditions dictate fewer implants, an implant-retained, tissue-supported prosthesis is indicated. Multi-unit abutments are precisely machined from titanium alloy and are available with a variety of collar heights to achieve optimal emergence from shallow or deep gingival wells. Multi-Unit Abutments are also available in three angulations: Straight (0°), 17° and 30°. To maximize the angle-correcting attributes of the multi-unit abutment, be sure to rotate the implant upon final seating so that one side of the internal connection geometry (flat or lobe) is oriented to serve as the base of angulation, in accordance with the restorative treatment plan. Contraindications The following conditions would contraindicate use of Preat Multi-Unit Abutments: ▪ Greater than 32 degrees divergence from parallel for a splinted restoration when using 17- degree angled multi-unit abutments Small diameter implants and angled abutments are not recommended for use in the posterior region of the mouth.
