Evaluation of an Angio-Osseo Inductive Bone Ceramic versus demineralised freeze-dried bone allograft in the treatment of periodontal intrabony defects: a randomised controlled clinical trial

Introduction: Periodontal intrabony defects (IBDs) respond favourably to regenerative periodontal therapy. Various graft and non-graft materials have been used, with non-allogenic bone substitutes offering the potential to enhance clinical outcomes and radiographic defect resolution. Angio-Osseo Inductive Bone Ceramic (ABC), a novel ion-doped biphasic calcium phosphate graft, has shown promise due to its osteogenic and angiogenic potential. Aim: The study aimed to compare the clinical and radiographic outcomes of ABC and demineralised freeze-dried bone allograft (DFDBA) in the surgical management of periodontal IBDs. Materials & methods: = 15). Clinical parameters, including Plaque Index (PI), Gingival Index (GI), probing pocket depth (PPD), and clinical attachment level (CAL), were recorded at baseline, 3 months, and 6 months. Radiographic bone fill was assessed at 3 and 6 months using standardised digital radiovisiography. Results: < 0.05). Conclusion: Both ABC and DFDBA were effective in the treatment of periodontal IBDs. However, ABC demonstrated statistically significant improvement in defect fill, supporting its potential as a novel alloplastic alternative to conventional allograft.
