custom made zirconia anchorages, in single tooth implant-supported restorations of the maxillary anterior region. Sixty-five patients, with a total of 74 missing maxillary teeth, were selected in the period from February 2007 to July 2010. Two different ways of custom made zirconia abutment and final prosthetic restoration were evaluated: a standard zirconia abutment associated with a pressed layer of lithium disilicate with an all-ceramic cemented restoration versus one-piece restoration with the facing porcelain fired and pressed straight to the custom made zirconia abutment. In 29 cases, the restoration consisted of an all-ceramic restoration for cementation (two pieces); in 45 cases the restoration was a screw-retained restoration (one piece). Three all-ceramic restorations broke during the observation time. Two one-piece restorations fractured after 26 months. At follow-up examination there were no significant differences between one-piece and two-piece groups regarding the PI, BI, and MBL. Awaiting studies with longer follow-up times, a careful conclusion is that zirconia anchorages for single-implant restorations seem to demonstrate good short-term technical and biological results.</p></div></front><back><div1 type="bibliography"><listBibl><biblStruct><analytic><author><name sortKey="Albosefi, A" uniqKey="Albosefi A">A.

Three all-ceramic restorations broke during the observation time. Two one-piece restorations fractured after 26 months. At follow-up examination there were no significant differences between one-piece and two-piece groups regarding the PI, BI, and MBL. Awaiting studies with longer follow-up times, a careful conclusion is that zirconia anchorages for single-implant restorations seem to demonstrate good short-term technical and biological results.</p></abstract></article-meta></front><floats-group><fig id="fig1" orientation="portrait" position="float"><label>Figure 1</label><caption><p>Preoperative view of left lateral incisor affected by periodontal disease.</p></caption><graphic xlink:href="BMRI2016-8767845.001"></graphic></fig><fig id="fig2" orientation="portrait" position="float"><label>Figure 2</label><caption><p>Delayed placement of single tooth implant 30 days after tooth extraction.</p></caption><graphic xlink:href="BMRI2016-8767845.002"></graphic></fig><fig id="fig3" orientation="portrait" position="float"><label>Figure 3</label><caption><p>Periapical Rx immediately after implant placement with provisional screw anchorage.</p></caption><graphic xlink:href="BMRI2016-8767845.003"></graphic></fig><fig id="fig4" orientation="portrait" position="float"><label>Figure 4</label><caption><p>Temporary screw rehabilitation.</p></caption><graphic xlink:href="BMRI2016-8767845.004"></graphic></fig><fig id="fig5" orientation="portrait" position="float"><label>Figure 5</label><caption><p>Preoperative occlusal view of the maxillary first right premolar.</p></caption><graphic xlink:href="BMRI2016-8767845.005"></graphic></fig><fig id="fig6" orientation="portrait" position="float"><label>Figure 6</label><caption><p>Periapical X-ray at baseline showing the tooth fracture and decay of the first right premolar.</p></caption><graphic xlink:href="BMRI2016-8767845.006"></graphic></fig><fig id="fig7" orientation="portrait" position="float"><label>Figure 7</label><caption><p>Periapical Rx of temporary screw rehabilitation.</p></caption><graphic xlink:href="BMRI2016-8767845.007"></graphic></fig><fig id="fig8" orientation="portrait" position="float"><label>Figure 8</label><caption><p>The definitive custom zirconia-disilicate pressed anchorage and disilicate monolithic restoration.</p></caption><graphic xlink:href="BMRI2016-8767845.008"></graphic></fig><fig id="fig9" orientation="portrait" position="float"><label>Figure 9</label><caption><p>The periapical radiograph of the implant and the cement restoration (two pieces) 36 months after implant loading.
