Summary

Atrophic ridge augmentation utilizing guided bone regeneration (GBR) has become a major treatment option to provide optimal bone support for osseointegrated dental implants. GBR was initially employed to treat simple defects, including dehiscence and fenestration defects. In addition, GBR has been utilized for horizontal and vertical ridge augmentations and has demonstrated reproducible outcomes, with high implant survival rates and low complication rates. The results of recent clinical and histologic studies of ridge augmentation with GBR indicated that autogenous bone graft may be a suitable material for staged localized ridge augmentation in both horizontal and vertical augmentations. The main advantages of autogenous grafts are their osteogenic, osteoinductive and osteoconductive capabilities. Because of these qualities, autogenous grafts are considered by many to be the gold standard for bone regeneration

Conditions

  • Posterior Mandible With Deficient Ridge Height

Interventions

DEVICE

autogenous rings with GBR and autogenous graft with ti-mesh

* Autogenous Onlay ring block harvested from either mandibular ramus or chin will be placed over the defected site and fixed using titanium screws (1.6mm diameter) and then GBR using autogenous particulate will be placed around and over the blocks and covered with a resorbable bilayer collagen membrane (Bio-Gide®, Geistlich, USA) * Autogenous bone graft will be placed on the defected site and covered by a titanium mesh which will be fixed by titanium screws. * Flap advancement will be acquired by releasing the mylohyoid muscle attachment from the lingual flap and periosteal releasing incision for the buccal flap to provide tension free closure. * The flap will then be copiously irrigated with saline in preparation for closure. * The flap will then be closed using horizontal mattress and interrupted 4/0 polypropylene sutures.
