Horizontal augmentation of the atrophic ridge: Split crest technique

Therapy with osseointegrated implants has been shown over the years to be the best choice in the rehabilitation of edentulous jaws. The challenge of modern implant dentistry is to solve clinical situations found in most edentulous ridges that made it difficult or prevented the replacement of teeth with osseointegrated implants. It is known that the success of therapy with osseointegrated implants depends on adequate remaining bone volume and height. To resolve these defects, mainly horizontal defects, techniques were developed that enable the return of the pre-tooth loss socket dimension: distraction osteogenesis; guided bone regeneration (RGO); Interpositional and Split Crest osteotomies. The Split Crest (RSP), also called lateral expansion of the crest, increases the width of the edentulous ridge through osteotomies in the region of the buccal wall and thereby moving away from the lingual wall to gain the horizontal dimension, creating conditions for the correct positioning of the dental implant.
