Abstract

The insufficient height and width of the edentulous alveolar ridge can complicate the implant rehabilitation of the posterior mandible. The aim of this technical note is to describe an inlay technique without the use of mini-screws and miniplates for the stabilization of the transported bone fragments. The inlay technique involves the first horizontal osteotomy performed 2-3 mm above the mandibular canal, and two oblique cuts are made using an ultrasonic device. The final phase of the vertical augmentation is performed with a dedicated instrument. The space between basal bone and coronal osteotomies segment is maintained by a hard equine block. The residual space is filled by particles of cortical-cancellous equine bone. This technique showed that equine collagenated blocks presented higher stability, allowed the elimination of the use of mini-screws and miniplates, and simplified the sandwich technique.
