Summary

This study aims to answer the question whether the use of a fluorescent layer over white zirconia abutments will improve the aesthetic outcomes of implant borne single-tooth restorations when compared to the use of non-layered white zirconia abutments. The study is designed as a parallel, single-centre and double blind clinical trial. Patients in need of a single tooth implant in the maxilla (from right second premolar to left second premolar, both included) with the presence of adjacent natural teeth will be randomly divided into two treatment groups: using white yttria-stabilized zirconia abutment (PYRCA; BioHorizons, Birmingham, EEUU) with immersion in fluorescent liquid (Zirkonzahn, South Tirol, Italy)(test group) or white yttria-stabilized zirconia abutment (PYRCA; BioHorizons, Birmingham, EEUU) without immersion in fluorescent liquid (control group). 1 and 12 months after crown placement, patients will be recalled and subjected to aesthetic, clinical, radiographic and patient centered outcomes.

Conditions

  • Edentulous Alveolar Ridge in the Aesthetic Zone

Interventions

OTHER

Implant placement and prothesis made with different types of abutment

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.
