Mandibular ridge augmentation and resorption with various visor procedures.
Modifications of the visor osteotomy for ridge augmentation are presented. Cases treated by these methods were studied for bone augmentation and resorption by measurements made on lateral cephalometric headplates, and compared with other procedures using interpositional or rib onlay techniques. It was found that the modified visor procedures fulfilled the criteria for the ideal ridge augmentation technique better than the other methods. Their main advantage is that they use the bone available from the mandible itself, with only a secondary role for the bone graft material in most instances.
