| #1 | P—Edentulous patients treated with dental implants | |
| ((“Dental Implants” (MeSH Terms)) OR (Dental Implant † (Supplementary Concept))) | ‘tooth implantation’ OR ‘tooth implant’ OR ‘dental implant’ OR ‘dental implants’ | |
| #2 | I—Rehabilitation with zirconia or titanium–zirconium dental implants | |
| ((“Zirconium” (MeSH Terms)) OR (Zirconium Oxide (Supplementary Concept)) OR (Zirconia (Supplementary Concept)) OR (Yttria Stabilized Tetragonal Zirconia (Supplementary Concept)) OR (“Ceramics” (MeSH Terms))) | ‘zirconium oxide’ OR ‘zirconium’ OR ‘ceramics’ OR ‘yttria stabilized tetragonal zirconia’ | |
| #3 | C—Rehabilitation with titanium dental implants | |
| #4 | O—Clinical outcomes (survival rate, success rate, marginal bone loss, probing in-depth, bleeding on probing, and osseointegration level) | |
| #5 | T—At least 6 months | |
| Search Combination | (#1 AND #2) No combination conducted done with #3, and #4 since most of the papers on dental implants are about titanium, and the combination with keywords related to outcome would limit the search even more. Item #5 was manually evaluated. |
