上顎骨の著しい劣成長を伴う両側性口唇口蓋裂二症例において,REDシステムによる上顎骨延長術を施術した際の,上顎骨および上顎骨に対する歯の移動様相を明確にするために検討を行ったので報告する.症例1は手術時年齢11歳6か月の女子.症例2は手術時年齢16歳8か月の女子.両症例とも顎裂部自家腸骨細片移植術を行った.また,症例2は延長終了22日後に下顎後退術を併せて施術した.骨延長術はREDシステムを応用し,延長装置を上顎歯列に固定した後,Le Fort I型骨切り術を施術し,朝夕0.5mmずつ1.Omm/日の割合で延長を行った.上顎骨と歯の移動様相を正確に評価するため,Le Fort I型骨切り術中にインプラントピンを骨切り線上下に計4本埋入し,骨内マーカーとした.術前から延長終了後2年までの側面セファロトレース上で検討を行った.延長終了時,上顎骨の延長量は症例1で前方11.2mm,下方1.3mm,症例2で前方7.5mm,下方2.6mmであった.延長後変化量は,症例1で-1.8mm(-16.0%)認められたが,症例2では,延長術後も+1.Omm(+13.3%)の前方移動が認められた.術中の歯の移動は両症例とも,水平方向より垂直方向への移動が多く認められた.

We used a pendulum appliance for distal and palatal movement, and depression of the upper bilateral second molar to correct scissors bite and deep overbite. As a result, we were able to achieve a good arrangement of occulusion without root resorption. The in superposition of the Cephaologram trace on a three-dimensional shape measuring system using a dental cast at initial diagnosis was useful for planing orthodontic treatment with visual and numerical prediction of tooth movement.

In the field of jaw deformities, there has been an increase in the number of middle-aged and elderly patients selecting surgical correction in recent years. However, treatment of these patients might be difficult because of poor oral condition such as edentulous jaws and tooth loss. Under these conditions, an interdisciplinary approach including orthodontics, oral surgery and prosthodontics is required for the treatment of jaw deformity. We report a patient with edentulous jaws who was treated with orthognathic surgery using the interdisciplinary approach.The patient was a 42-year-old male diagnosed with mandibular protrusion. He was at risk of chronic diseases of the mouth, including dental infection and tooth loss. As a result of diagnosis of prosthodontics, all teeth were extracted to correct severe oral hygiene. Before corrective jaw surgery, wax dentures were made on the assumption of post-surgery oral condition. By using the wax dentures, dental implants were positioned on the edentulous jaws and provisional teeth were made. Regarding orthognathic surgery, intraoral vertical ramus osteotomy was performed on the right side of the mandible and sagittal split ramus osteotomy was performed on the left side. Twelve months later, osteotomy was performed and the final stage of prosthodontic treatment was started.Following this interdisciplinary approach to jaw deformity treatment, the patient with edentulous jaws is satisfied with the stable occlusion and better facial contour.
