At the second molar level it is removed the cortical lamella sector equal to the distance necessary for attaining an adequate jaw relation. It is sectioned the bone lamella with passage in the retromolar region, it is separated with an osteotome the sectioned bone sector, which is pushed forward up to the attainment of the correct occlusive contact and it is fixed with sutures.
