  Objectives This study evaluates the safety and osteoconductive potential of a ceramic TiO2 scaffold in human alveolar bone, hypothesising that placement in human extraction sockets is safe, supports bone ingrowth and preserves ridge dimensions. Material and Methods Nine subjects requiring the extraction of ≥ 1 premolar or molar tooth were enrolled. Full-thickness mucoperiosteal flaps were elevated. Following tooth extraction, porous ceramic TiO2 scaffolds were adjusted chair-side, placed into the extraction socket and covered by a resorbable collagen membrane. After 6 months of healing, before dental implant placement, a biopsy was performed at the site where the scaffold had been placed. Histomorphometric and micro-CT analyses were made. CBCT images were made at baseline and at 6 months to assess alveolar ridge dimensional changes. Implants placed in regenerated bone were followed for 21 months. Results Scaffold customisation with chairside adjustment was straightforward. No serious adverse events were observed during the 6 months following scaffold implantation. One scaffold was removed due to an early exposure, while the remaining 9 scaffolds successfully integrated. Two sites presented with minor soft tissue dehiscences at 1–2 weeks, which healed spontaneously. Micro-CT and histology confirmed new bone formation. Soft tissue healing was favourable, with no adverse reactions. Dimensional analysis revealed minimal changes in alveolar ridge width and height, indicating effective preservation of volume. Conclusions This clinical study confirms that TiO2 scaffolds are a safe and effective option for promoting bone regrowth and preserving volume in human alveolar bone, thereby facilitating bone formation and maintaining ridge dimensions post-extraction.
