Cortellini S, et al. - Experts investigated the effects of a new GBR technique with a tissue engineering approach in this single cohort observational study. An average linear horizontal bone gain of 4,6 mm, 5,3 mm and 4,4 mm, measured at 2, 6 and 10 mm from the alveolar crest, respectively was demonstrated by the superimposition of pre-operative and post-healing CBCT scans. In order to augment deficient alveolar ridges, L-PRF block could prove to be a suitable technique.
