Greffes osseuses des secteurs mandibulaires postérieurs par technique de « coffrage »

The bone volume reconstructed with the formwork technique allows anchoring implants more than 8 mm long. The proximity of the inferior alveolar nerve does not contra indicate this technique. The formwork size and its positioning on the alveolar crest can be adapted to prosthetic requirements by using osteosynthesis plates. The lateral implant walls are supported by the formwork cortices; the implant apex is anchored on the native alveolar crest. The primary stability of implants is high, and the torque is important. The ramus harvesting decreases operative risks.
