Aesthetic Outcomes of Single Tooth Implant-supported Restorations in the Anterior Maxilla With Either White Zirconia or Fluorescent White Zirconia Abutments

Dental implants (Tapered internal implants; BioHorizons, Birmingham, EEUU) will be placed in healed residual ridges (minimum of 4 months after tooth extraction). After connecting healing abutments, the flaps will be sutured around the abutments for non-submerged healing. An abutment composed of white yttrium oxide stabilized zirconia abutment (PYRCA; BioHorizons, Birmingham, EEUU) previously immersed in fluorescent liquid (Zirkonzahn, South Tirol, Italy) will be placed in the test group, whether in the control group the same abutment will be used but without fluorescent layer. The selected abutment is machined and designed for use with cemented restorations. A single experienced restorative dentist using one dental laboratory carried out all the prosthetic procedures. Single crowns full ceramic will be performed and cemented with RelyX™ Luting Cement.
