Autogenous bone block with immediate implant placement in anterior maxilla

Anterior teeth root fractures and chronical fistula usually results in bone deficiency of anterior maxilla. Insufficient bone volume in the anterior maxillofacial region often requires reconstructive surgery for ridge augmentation to make placement of endoosseous implants possible. In the majority of the cases the bone block grafts were harvested from the mandible using specially designed instruments. A patient was a 36-year-old male with clinical and x-ray signs of a vertical fracture of the endodontically treated maxillary left central and lateral incisor. After extensive diagnostic procedures, therapeutical plan was made: two dental implants placement (XiVE® ; ; ; Implant System) immediately after teeth extractions and bone defect augmentation in the area 21 and 22. After immediately implants placement, autologous bone graft was used for remaining bone defect of the buccal cortical plate, combined with heterogenous bone filling material (Bio-Oss® ; ; ; , Geistlich, Germany) and finally covered with resorptive membrane (Bio-Gide® ; ; ; , Geistlich, Germany). During the osseointegration period, onlay composite resin bridge was made as the temporary prosthetic solution. Following the osseointegration period of 6 months, all-ceramic single tooth crowns on zirconium oxide abutments were used as final prosthodontic restorations. The patient exhibited neither clinical nor radiologic complications throughout the 6 months period of clinical monitoring.
