The aim on this study was to investigate the hard tissue alterations of the alveolar bone crest following tooth extraction and immediate implant placement using cone beam computed tomography. Twelve consecutive patients in need of an immediate dental implant were included in the study. An implant of proper length was placed in the extraction socket wit the coronal margin of the rough surface generally flush with or deeper than the buccal alveolar bone crest. The results should be viewed with caution because of the small number of cases examined.
