Volumetric changes associated with immediate implant placement and Bio-Oss collagen

Volumetric changes associated with immediate implant placement and Bio-Oss collagen is observed. Hence, Thirty patients requiring single-tooth extraction and immediate implant placement in the anterior maxilla were randomly allocated into two groups: Group A (n=15) received immediate implants with Bio-Oss Collagen filling the gap and Group B (n=15) received immediate implants without grafting. Cone-beam computed tomography (CBCT) scans were obtained immediately post-operatively and at six months. Volumetric measurements were performed using three-dimensional image analysis software. Statistical analysis included paired and independent t-tests. Bio-Oss Collagen significantly reduced volumetric bone resorption following immediate implant placement, demonstrating superior preservation of peri-implant hard tissue dimensions compared to non-grafted sites.
