Orthopedic surgery for edentulous malocclusion | [Chirurgia ortopedica nell'edentulo disgnatico.]
No full textThe treatment of maxillary deformities in edentulous patients, with reference to tooth-bearing ones shows some differences concerning both the treatment planning and the surgical procedures. The Authors present in detail their way of planning the treatment and some expedients and modifications they apply to the usual surgical procedure in this special kind of maxillary deformities
Bilateral condylar atrophy after combined osteotomy for correction of mandibular retrusion. A case report
No full textBilateral atrophy of the mandibular condyles after maxillo-mandibular surgery for correction of a Class II open-bite is reported. Although a definite cause could not be ascertained, it is postulated that a biomechanical phenomenon based on increased muscle tension was the most likely causative mechanis
Aggressive juvenile fibromatosis[La fibromatosi aggressiva giovanile.]
No full textAggressive juvenile fibromatosis is not metastasizing disease characterized by a neoplastic proliferation of fibroblasts that rarely involves surrounding bone. The Authors describe one case observed by them and suggest the surgical procedure as elective treatment of the disease. In cases where a mandibular resection is performed, a simultaneous bone reconstruction, when feasible, is indicated

On the feasibility of intraoral maxillo-malar osteotomy
No full textThe maxillo-malar osteotomy is one of the osteotomies developed over the years to correct the deformities of the midface without modifying the nasal projection. After having for many years approached the osteotomy through the classic double access, intraoral and subciliary, we verified the feasibility of this osteotomy via an intraoral route only. For this purpose we modified slightly the classic osteotomy lines, however still including in the mobilized fragment the most prominent and therefore the most aesthetically important portion of the zygoma. At the lower orbital rim the medial osteotomy cut is performed with a fissure bur, the lateral one with an oscillating saw. Both the osteotomies are extended posteriorly in the orbital floor with a fine osteotome. Then, after having performed all other osteotomy cuts, the maxillo-malar complex is down-fractured. The residual thin bone structures which connect the maxillo-malar complex to the cranio-facial skeleton are broken during a careful downfracture, avoiding fracture between the maxilla and zygoma. The complex is advanced and stabilized with intermaxillary fixation, osteosynthesis and bone grafts. A bone graft to the orbital floor is unnecessar
