Onlay lateral ridge bone grafting,horizontal osteodistraction, and Guided bone regeneration techniques. Lateral ridge split technique is a way to solve the problem of the width in narrow ridges with adequate height.
Simultaneous insertion of dental implants will considerably reduce the edentulism time. Dental implant placement in atrophic ridges with deficient ridges with onlay bone grafting techniques (Autografts/allografts) need some time between bone grafting and dental implant insertion (3-6 month) and there is always the possibility of bone graft failure.
Crest split augmentation technique with simultaneous implant insertion will reduce the time as well as the surgical procedures. Bone compression and increase in trabecular density are other advantages of this technique.
Survival rate of implants inserted in ridge split alveolar ridges is reported between 86% and 97%. Biomaterials or autogenous bone are used as interpositional grafting in this technique. Membranes do not necessarily increase the outcomes with this technique.
The patients’ acceptance rate for this technique is very high due to its low morbidity and shorter time intervals in comparison with autologous onlay bone grafting.
