Table 1. | PICOS guidelines |
| Patient and population (P) | Healthy patients with a horizontal alveolar deficiency following tooth loss, trauma or congenitally missing tooth/teeth. |
| Intervention (I) | Lateral alveolar ridge augmentation with an autogenous tooth block graft. |
| Comparator or control group (C) | Lateral alveolar ridge augmentation with an autogenous bone block graft. |
| Outcomes (O) | Survival of suprastructures, survival of implants, implant stability quotient, health status of the peri-implant tissue, gain in alveolar ridge width, postoperative dimensional changes of the alveolar ridge, patient-reported outcome measures, biologic and technical complications. |
| Study design (S) | Randomized controlled trials, controlled clinical trials, case-series and retrospective studies assessing lateral alveolar ridge augmentation with an autogenous tooth block graft compared with autogenous bone block graft. Moreover, human studies solely assessing lateral alveolar ridge augmentation with an autogenous tooth block graft were included as non-comparative studies. |
| Focused question | Are there any differences in implant treatment outcome following lateral alveolar ridge augmentation with an autogenous tooth block graft compared with autogenous bone block graft? |
