Clinical performance of tooth root blocks for alveolar ridge reconstruction. Int J Oral Maxillofac Surg. 2022 May;51(5):680-6890901-502710.1016/j.ijom.2021.08.019https://hdl.handle.net/20.500.14352/93799This systematic literature review set out to investigate the clinical outcomes of autogenous tooth root blocks used for ridge augmentation: survival rates, block resorption, implant survival, post-surgical complications, and histology findings. This review followed PRISMA guidelines. An automated search was made in four databases, supplemented by a manual search for relevant articles published before December 2020. The quality of evidence provided was assessed with the Newcastle-Ottawa Quality Assessment Scale and the Joanna Briggs Institute Critical Appraisal tool. Seven articles fulfilled the inclusion criteria and underwent analysis. The articles included a total of 136 patients, who received 118 autogenous tooth root blocks and 26 autogenous bone blocks showing block survival rates of 99.15% and 100%, respectively. Tooth root blocks presented a mean bone gain that was similar to autologous bone blocks but showed less resorption. The implant survival rate was 98.32% for autogenous tooth root blocks. Reconstruction of alveolar crests by means of autogenous tooth root blocks appears to be a satisfactory option for single-tooth gaps and low grades of bone atrophy in terms of the survival of the bone block and the implants placed subsequently. More research providing long-term data is needed to confirm these findings.engAttribution 4.0 Internationaljournal article1399-0020https://www.sciencedirect.com/science/article/pii/S0901502721002940?via%3Dihub34507879open access616.314616.31-089616.314-089.843616.314.17-008.1Alveolar ridge augmentationsBone transplantationDental implantsTooth extractionOdontología (Odontología)Cirugía bucofacialImplantes dentalesPeriodoncia32 Ciencias Médicas3213 Cirugía3213.13 Ortodoncia-Estomatología
