References: Two Stage Mandibular Ridge Split Technique

1. Coronal view of mandible.
2. Make a full thickness flap and a narrow crestal osteotomy. Make a wider horizontal osteotomy 3.0mm above the mandibular canal.
3. Lateral view of two thin vertical osteotomies and a wider horizontal osteotomy.
4. Close for three or four weeks to re-establish blood supply to the cortical bone.
5. Without reflecting the buccal periosteum, drill a 2.0mm pilot hole to a depth below the horizontal osteotomy.
6. Buccal cortex is outfractured as wider reamer burs are used.
7. Insert implant into a widened ridge apical to the horizontal osteotomy.
8. Allow a minimum of four months for osseointegration.
