Vertical reconstruction of the posterior atrophic mandible with two techniques, interpositional graft and autogenous onlay bone block from Ramus.
Conditions
Interventions
Intervention 1: The first intervention group (interpositional technique): the full-thickness flap will be cut the vestibular paracrestal and will be extended to the disto-buccal posterior mandible, an
Upper displacement of the upper segment by maintaining the lingual attachment and releasing the mylohyoid muscle from the lingual surface of the lower bony segment will be taken, then the upper segmen
