Sausage technique surgical procedure
Fig. 1: Occlusal view of severely atrophied posterior mandibular ridge.
Fig. 2: Occlusal view of the thin posterior mandibular ridge. A full thickness, mid-crestal incision is used in the keratinised gingiva. For surgical access, the two divergent vertical incisions are placed.
Fig. 3: The recipient bone bed is prepared with multiple decortication holes and autogenous bone is harvested from the external oblique ridge using half of a 4mm trephine.
Fig. 4: Buccal view after application of a 1:1 mixture of autogenous particulated bone and Geistlich Bio-Oss granules. Note that the Geistlich Bio-Gide membrane is secured on the crest before the application of the graft.
Fig. 5a: Buccal view of a single Geistlich Bio-Gide membrane, which is fixed with titanium pins. The pins are 1mm diameter, which are stable in the cortical bone of the mandible.
Fig. 6: A periosteal releasing incision is made connecting the two vertical incisions until enough elasticity is achieved. The flap is then sutured in two layers.
Fig. 7: Buccal view of the soft tissues at three weeks of uneventful healing.
Fig. 8: Occlusal view of the newly formed ridge at re-entry after seven months.
Fig. 9: Two implants were placed with good primary stability.
