The relationship between recipient condition and the period required for periodontal healing of autotransplanted teeth was studied. The period for periodontal healing was evaluated on the basis of regeneration of the periodontal space and lamina dura on dental radiographs. Age, sex, site of transplantation, period after tooth extraction at the recipient site, and the timing of occlusal function were the recipient factors examined. The mean periods required for regeneration of the periodontal space and lamina dura were 3.7 months and 7.6 months, respectively. Regeneration of the periodontal space was not influenced by any recipient factor, whereas regeneration of lamina dura was associated with the period after tooth extraction, site of transplantation, and timing of occlusal function. It was suggested that regeneration of the lamina dura may not totally depend on that of the periodontal space.
