A recent study evaluated bone regeneration around delayed implants positioned in large bone defects, that were filled with reactive soft tissue. Results were calculated using cone beam computed tomography (CBCT) and done at a follow-up of 3 years.
Three months after extraction, CBCT revealed a bone volume gain both for single-rooted and multirooted sites: an overall mean bone level of 8.34 ± 3.18 mm was calculated, and implants were placed. At the 3-year follow-up, CBCT revealed bone maintenance, with mean levels of 10.47 ± 3.68 mm. Statistically significant differences were not observed between 3-month and 3-year bone levels,
