Abstract Aim of the study: was to assess bone and soft tissue changes after tooth extraction and immediate implant insertion with immediate provisionalization in the anterior maxilla Methodology: 30 immediate implants were placed in anterior maxilla, a novel synthetic bone graft (Geistlich Bio-Oss® ) , nano bone ( Nano streams) was used to fill the gap between the implant surface and the alveolar bone. Implants with (3.7*14) diameter compared to the size of the socket were used. A fixed screw retained provisional restoration was provided immediately after implant placement. Cone beam computed tomography (CBCT) scans were taken to evaluate bone changes immediate after surgery and after 6-months follow up. To evaluate soft tissue changes, clinical vertical measurements were performed by using PES Result: the maen horizontal bone loss for group I was 0.671mm , for group II was 0.380mm ,and for group III was 0.289mm . This was statistically not significant; p=0.057.the mean vertical bone loss for group I was 0.212 mm , for group II was 0.233mm and for group III was 0.262mm. This was statistically not significant; p=0.807. Conclusions: •Immediate implant with immediate temporization using graft materials to augment jumping gap is successful treatment modality for rehabilitation of hopless teeth in the esthetic zoneThe type of graft materials doesn’t significally affect on the outcome (horizontal and vertical bone loss) following implant installation with immediate temporization in the esthetic zone. |
