Prosthetic flexibility Yellow-colored QN (Q-Lock Narrow) prosthetic components are intended for narrow S2.9 implants.BioniQ abutments present a wide range of options for individual solutions and customization according to specific needs and the patient's dentition. A narrower diameter of prosthetic components – compared to the implant diameter – allows better soft tissue management. The dual function connection allows bridge restorations to be fixed to the implant without the need for multi-unit abutments.
