Abstract

Lack of sufficient bone to place an implant at the most functionally and esthetically appropriate position is a common problem, especially in the maxillary anterior esthetic zone region. A surgical bone spreading technique is proposed to augment the alveolar ridge for horizontal defects through a localized alveolar osteotomy and interpositional bone graft. Bone spreading technique (BST) is horizontal augmentation with minimal trauma for simultaneous implant placement. The foremost advantage of this method is that the buccal wall expands after the medullar bone is compressed against the cortical bone. The lateral dilation and compaction of the medullar bone enhances primary stability. 
Keywords: Deficient alveolar bone width, ridge expansion, bone spreading technique, dental implant, guided bone regeneration
