Bottom Line: A 4 × 6 × 3 cm cyst was discovered in the left maxillary molar region and enucleated.A fixed denture was loaded over the implants after 3 months.Complete alveolar bone loss extending to the cranial base can be reconstructed with transport distraction osteogenesis.

ABSTRACT
Severe bone loss due to pathology in the maxillary tuberosity region is a challenging problem both surgically and prosthetically. Large bone grafts have a poor survival rate due to the delicate bony architecture in this area and presence of the maxillary sinus. Our case presentation describes a new technique for reconstructing severe bony defect in the maxillary tuberosity with horizontal distraction osteogenesis in a 45-year-old man. A 4 × 6 × 3 cm cyst was discovered in the left maxillary molar region and enucleated. Three months postoperatively, the area had a severe bone defect extending to the zygomatic buttress superiorly and hamular notch posteriorly. Three months later, a bone segment including the right upper second premolar was osteotomised and distracted horizontally. The bone segment was distracted 15 mm distally. After consolidation, implants were placed when the distractor was removed. A fixed denture was loaded over the implants after 3 months. Complete alveolar bone loss extending to the cranial base can be reconstructed with transport distraction osteogenesis. Distalisation of the alveolar bone segment adjacent to the bony defect is an easy method for reconstructing such severe defects.

Mentions: After a 7-day healing period, the distractor was activated by 1 mm once daily for 15 days. After full activation, the distractor was left in situ for the consolidation phase. Six weeks later, the distractor was removed and two dental implants were placed in the new bone. After 3 months for osseointegration, we realised that the implants were not aligned on the proper axis and position on CT (Figure 4). To correct this situation, a subapical osteotomy including the implants was performed and a block autogenous graft was taken from the mandibular symphysis and adapted to the superior border of the osteotomy line.
