Six cases with severely atrophic edentulous alveolar ridges, in which subperiosteal tissue expander (STE) was used before ridge augmentation with hydroxyapatite-tricalciumphosphate compound (HA-TCP) particles, were presented. In many cases, full inflation of the STEs could be achieved immediately after insertion thereof. One week after full inflation of the STEs, implantation of HA-TCP particles was performed. At that time, relatively firm subperiosteal envelopes were observed. Since the envelopes prevented migration of the particles, secondary vestibuloplasty due to loss of depth of the vestibule was not necessary except for one case that reguired removal of denture fibrosis. In all cases, functional and stable ridges were formed. As for complications, one patient had unilateral paresthesia of the lower lip and another had perforation and dehiscence.
