Advanced Techniques: Two Stage Mandibular Ridge Split

Two Stage Mandibular Ridge Split Technique


Coronal view of mandible.	Make a full-thickness flap and a narrow crestal osteotomy. Make a wider horizontal osteotomy 3.0mm above the mandibular canal.

Lateral view of two thin vertical osteotomies and a wider horizontal osteotomy.	Close for three or four weeks to re-establish blood supply to the cortical bone.

A Curved Cottle chisel is used to separate the buccal plate.	Buccal plate separated, but remains attached to the buccal periosteum using Bicon's Bone Graft Syringe.

Without reflecting the buccal periosteum, drill a 2.0mm pilot hole to a depth below the horizontal osteotomy.	Buccal cortex is outfractured as wider reamers are used.

Insert implant into a widened osteotomy apical to the horizontal cut. Allow a minimum of four months for osseointegration.
