. Group A, received ABG cylinders obtained from the chin and organic bovine bone mineral particles (Bio-Oss xenograft) along with an absorbable collagen membrane. ABG cylinders from the chin and biphasic alloplastic (EthOss) grafting material made of CS (35%) and TCP (65%) were given to Group B. CBCT scans were conducted before bone augmentation surgery, one week and 6 months postoperatively
