Four models with the implant and four models without the implant were constructed. Four levels of alveolar bone loss (0, 2, 4 and 6mm) were studied. The model with the implant was consisted of two maxillary second premolars, their associated periodontal ligament and alveolar bones, palatal bone, palatal implant and transpalatal arch. The model without the implant was used to compare with the model with the implant. The horizontal force (mesial 5N, palatal 1N) was loaded at the buccal bracket of each second premolar. The stress in the periodontal ligament, implant and surrounding bone were calculated. The results showed that the palatal implant could significantly reduce von Mises stress (maximum von Mises stress was reduced from 29.63% to 44.30% with the alveolar bone loss from zero mm to six mm) and make stress even distribution in the periodontal ligament. The stress in the implant and surrounding bone was very low. These results suggested that palatal implant is a good tool to enhance the anchorage of teeth with alveolar bone loss.", "subitem_description_type": "Abstract"}, {"subitem_description": "本研究の目的は、第二小臼歯部の歯槽骨の吸収程度とこれに連結したインプラントによる加強固定の効果について、有限要素法を用いて検討することとした｡歯槽骨の吸収の程度を4段階(0、2、4、6mm)設定し、それぞれインプラント有りと無しのモデルについて調べた。インプラントのあるモデルは、左右側の上顎第二小臼歯、歯根膜、歯槽骨、口蓋骨、バラタルインプラント、インプラントと小臼歯とを連絡するパラタルバーで構成した｡インプラントのないモデルは、上述のモデルにおいてインプラントを除外し、他は同じとした。水平力として、近心方向に5Nと口蓋方向にlNを両側の上顎第二小臼歯の頬側ブラケットに負荷した｡この荷重を負荷した時、歯根膜、インプラントとその周囲の骨に現れる応力を算出した｡その結果、インプラントを用いることで、設定した0～6mm歯槽骨の吸収したモデルにおいて、von Mises stressが歯根膜部で29.63～44.30%の減少した｡インプラントとその周囲の骨に現れる応力は、きわめて小さかった｡このことより、歯槽骨の吸収を起こしている歯に対して、加強固定のためにバラタルインプラントが有効であることが示唆された｡", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3":
