ABSTRACT
The posterior mandible may be challenging due to insufficient height and width of the edentulous alveolar crestal bone. The aim of this case report was to use an inlay technique without the use of miniscrews and miniplates for the stabilization of grafted bone fragments. A 54-year-old patient was treated with a horizontal osteotomy performed 2-3 mm above the mandibular canal, and two oblique cuts were made using an ultrasonic. The final phase of the osteotomy was performed with a lever for dental extraction. One miniblock of equine bone was inserted between the coronal osteotomized segment and the mandibular basal bone. Particles of cortical-cancellous equine bone filled the residual space. A resorbable collagen membrane was used for covered the biomaterials and miniblock. Four months after surgery, a panoramic X-ray was taken before implant insertion. No dehiscence of the mucosa was observed at the marginal ridge of the mobilized fragment. Rx showed a mineralized zone between the osteotomized segment’s basal bone and coronal portion. This case report showed that equine collagenated blocks present higher stability, allowing to eliminate the use of miniscrews and miniplates, thus simplifying the sandwich technique.
