Ceramic-based 3D printed bone graft in bone tissue reconstruction: a systematic review and proportional meta-analysis of clinical studies

Le résumé fourni par la source

INTRODUCTION: This systematic review and proportional meta-analysis aims to evaluate the postoperative complication rate (CR%) of ceramic-based 3D-printed bone grafts based on the reported scientific articles conducted with human individuals. METHODS: MEDLINE and SCOPUS were used as information sources. The synthesis of the study was carried out from studies with human individuals and the use of 3D-printed bone graft-ceramic as inclusion criteria. Cohen's kappa (κ) was calculated for interrater reliability. Qualitative analysis was performed based on the characteristics and outcomes of the individual study, and quantitative analysis was performed using proportional meta-analysis for CR%. RESULTS: A total of 1352 records were identified through databases and resulted in 11 included studies (κ = 0.81-1.00) consisting of prospective clinical trials (64.63%), case series (16.67%), and case reports (18.18%). The overall postoperative complication rate was 14.3% (95% Cl: 0.19-53.6). The postoperative complication rate for studies conducted on the cranial defect, the maxillofacial-zygomatic defect, and the tibial-femoral defect was 2.7%, 11.1%, and 15.6%, respectively. This review also highlights common 3D printing techniques, materials, and grafs' characteristics, as well as their clinical applications. CONCLUSIONS: Ceramic-based 3D-printed bone grafts show potential as alternatives for bone tissue reconstruction.
