Brief summary

. 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

Detailed description

Two groups of forty patients participated in this prospective, controlled, randomized clinical investigation. 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
