It is also called as split bone block technique / shell technique.

• Mandibular bone blocks ( external oblique ridge ), which consists primarily of cortical bone and a low percentage of cancellous bone , are more resistant to revascularization and consequently may have poor regeneration potential . For this reason , the harvested thick bone blocks with the diamond disk according to the split bone block technique of the biologic concept of grafting procedures.
• Splitting the thick blocks into two thin blocks not only increases the number of bone blocks , offering the possibility to graft more surfaces in different forms , but also improves revascularization and regeneration.
• The thin blocks were stabilized at the recipient site with microscrews , and any gaps were filled with autogenous bone chips harvested from the donor site with a bone scraper .
• No biomaterials or membranes are used .
• This technique with pure autogenous bone , which has been used for 20 yrs , has shown a high success rate .
