    The aim of this study was to determine whether the trabecular structure of the jaw bone is related to systemic bone metabolism and fat metabolism. The unilateral mandiblar residual ridges of nine elderly women were imaged using the dental cone-beam CT system (CBCT), and the relationships between the three-dimensional bone morphometry data of the jaw bone and the right calcaneus bone mineral density, the blood metabolism markers, and the serum adipocytokines were statistically searched. As a result, the trabecular bone in the lower jaw was more plate-like as the calcaneus bone density was higher, and TRACP-5b had a significant correlation with BS/TV, Tb.N, N.Nd, and Euler numbers of jaw bones. In addition, leptin showed a significant negative correlation with N.Nd of mandible, indicating that trabeculae ruptured as leptin was higher.

    Long-term Care insurance(LTCI) fees were revised in April 2015, and the revision focused on support of oral ingestion and oral health of residents in LTCI facilities. To investigate claim rates and estimated billing amounts for these benefits; cooperation between LTCI facilities and oral health professionals(OHPs), questionnaire surveys were carried out to all LTCI facilities in a Prefecture in Japan
    Benefits for transition from tube feeding to oral ingestion, and maintenance of oral ingestion were claimed in about 10% to 40% of facilities. Benefits for “oral health management system” and oral health care by dental hygienists were claimed in about 70% and 20%. Employment of OHPs by LTCI facilities was were strongly associated with claims for these benefits, and billing amount was about 62,000 JPY/month higher significantly for facilities that employed OHPs.

    The purpose of this study was to establish a simulation model to predict bone tissue changes by occlusal force by means of 3-D finite element analysis. We established rat implant occlusion model first. Then, we used micro CT to have digital data of 3-D structure of the implant with surrounding bone tissue. Using 3-D finite element analysis program, we applied occlusal force to the implant and seek some correlation between the force distributions and bone tissue changes investigated by histological sections. As a result, we found that there were some correlations between those and it was shown that the bone tissue changes upon occlusal loading could be predicted by 3-D finite element analysis. The precision should be verified by further investigation yet.

    3次元有限要素モデルを用いて、過大な負担によるインプラント・骨の界面における広範な骨吸収現象を予測するためには、海綿骨を等方性のある材質としたモデル(従来モデル)より骨梁構造をシミュレートしたモデル(精密モデル)が適している事が、平成16年度に実施した撓骨のμCT画像を用いた研究より明らかとなった。この結果を踏まえ、平成17年度はより臨床条件に近い精密モデルの製作を目的として、ヒトの顎骨標本にチタンインプラントおよびアバットメントを植立させた標本のμCT画像によるコンピューター・シミユレーション・モデルを作成する為の条件確立を試みた。μCT装置を用い、X線がインプラントの長軸を通る方向に標本をセットし、70kV 100mA,75kV 100mAおよび80kV 100mAの管電圧電流条件にて撮影し、3次元再構築画像を比較検討した。3撮影条件の内、80kV 100mAで得られた画像は最も明瞭であったが、X線がインプラントおよびアバットメントの長軸を通ることが困難であった為、インプラント先端周囲の海面骨構造が不鮮明であった。次に、マイクロカッティング・マシンを用いて顎骨からインプラント植立部位を含む骨片を切り出し、X線がインプラントの長軸を横断する方向で、75kV 100mAおよび80kV 100mAの条件にて撮影し、3次元画像を再構築した。その結果、80kV 100mAの条件でX線がインプラントの長軸を横断する方向で撮影された画像が、最も明瞭に骨構造を描記していた。このμCTデータを原画像とし、3次元骨梁構造計測ソフト(TRI/3D-Bon, RATOC社)を用い、皮質骨、海綿骨、インプラントおよびアバットメントの2値化が可能であった。従って、本条件を用いる事によって、より臨床条件に近い精密モデル製作が可能である事が明らかとなった。

  • 疲労試験および有限要素法によるインプラントシステムの力学的分析

    ITIおよびBranemarkについてインプラントシステムの疲労強さの比較検討を行った。インプラントとして長さ10mmのソリッドスクリュー(ITI)とマークIV(Branemark)の各7本を用意し,それぞれにソリッドヘッドとCeraOneのアバットメントを結合した。各システムは骨吸収を近似してインプラントの底部から7mm深さをレジンブロック内にマウントした。アバットメントに白金加金のキャストクラウンをセメント合着し、咬合面から1.2mm離れた点において,インプラント軸に対して垂直に10kgの繰り返し荷重を加えた。150万回の荷重でも,ITIインプラントでは,セメント合着部は破損せず,インプラント/ソリッドヘッドの締結ネジも破折しなかった。しかし,Branemarkインプラントでは,7本のうち4本がアバットメントのゴールドスクリュー部で破折した。破折面の高さはインプラント周囲のレジン表面のそれに一致し,SEMで観察した破折面は典型的な疲労破壊の様相を呈していた。この結果から,モーステーパー結合のソリッドヘッド/ソリッドスクリューは,バットジョイント結合のCeraOneアバットメント/マークIVより,疲労に強いことが明らかになった(Fisher's exact testのp=0.035)。
    次に,インプラントシステムの応力を三次元有限要素法にて解析した.疲労試験で用いたインプラントシステムのコンポーネントを単純化して顎骨モデルに挿入し,上部構造の中央に垂直荷重と側方荷重をそれぞれ負荷した。側方荷重の場合,インプラント内に発生する応力は周囲骨レベルの高さに対応する位置で最大になり,これは疲労破折面の高さに一致していた。
    以上の結果から,ジョイントの種類,側方荷重,および周囲骨レベルがインプラントシステムの強さに大きな影響を及ぼすことが明らかになった。
