Standard Implants With Bone Regeneration vs Short Implants

A study designed as a randomized controlled trial of parallel group design will be conducted at the Dental clinic of the University of Valencia to compare, considering different parameters, the rehabilitation with dental implants of atrophic posterior mandibles or maxillae using short implants or longer implants with vertical bone regeneration with GBR. The hypothesis of the study is that both treatment options will be successful to rehabilitate atrophic posterior mandibles or maxillae. Moreover, more surgical complications will be encountered in the bone regeneration group.
