    Osseointegration depends on the activity of osteoblastic cells to form and maintain bone. Although changes in implant design, surgical technique, and restorative method may be improved with regard to osseous responses, the fundamental aspects of bone cell biology and osseous physiology must be considered as a source for additional clues of improving implant success. Particularly, molecular and cellular information concerning the process of osteogenesis at implant surfaces is presently required. The aim of this article is to identify molecular and cellular determinants of bone formation that may be used in clinical attempts to improve the application of endosseous implants for dental and craniofacial prosthetics. A review of bone biology, dental and orthopedic implant manuscripts was performed using published monographs and Medline. It is indicated that molecular and cellular approaches for formation of bone mass may be used to enhance or expand the application of dental implants. The regulation of cellular activity should be the guide to the development of novel strategies for improving tissue integration of dental prostheses.

    Morphological changes in the external nose after surgical anterior shift of the maxilla were evaluated. The absence of morphological change is desirable unless morphological modification is an objective of the surgery. Presently, however, the degree of postoperative morphological changes in the external nose is difficult to anticipate. Morphological changes are clinically encountered also during the period of postoperative orthodontic treatment. In this study,primarily postoperative morphological changes in the external nose and the course of such changes were evaluated. We examined 9 females who underwent surgical anterior shift of the maxilla at our university hospital school of dentistry, using standard lateral head X-ray films and front-view facial photographs in the natural position obtained before,1 month after, and 1 year after surgery. The apex of the nose was shifted anteriorly in all patients

    <br>1 month after surgery but returned posteriorly in 8 of the 9 patients after 1 year. Vertically, upward shifts of the nasal apex were observed in 7 of the 9 patients, and downward shifts were observed in the remaining 2.Returns to the preoperative level were observed in 7 of the 9 patients including those that showed downward shifts. The distance between the wings of the nose was increased in all patients 1 month after surgery. It showed a return in 4 of them after 1 year but increased further in the remaining 5. The acceptable range of morphological changes of the external nose varies among individuals and is difficult to evaluate using a uniform scale, but none of the 9 patients in this study complained about the postoperative nasal morphology. However, morphological changes did occur, and further improvernents in preventive measures against them are anticipated. Also, considerations of the external nose morphology are thought to be necessary in planning occlusal reconstitution.

    本講座開設後10年6ヵ月間に実施した静脈内鎮静法1313症例について分析検討した.他の診療各科の静脈内鎮静法に対する理解を深める努力と情報公開が必要であった.障害者の歯科治療における行動調節で静脈内鎮痛法を適用した群に対する静脈内鎮静法の適用を特に厳密に判定する必要があった.術中・術後合併症を認めた症例の処置時間は長時間であった.使用薬剤はミダゾラムが最も多かったプロポフォールは,今回検討は鎮痛法に用いた症例がすくなかった.患者の側に立って処置の侵襲を評価して,適用を決める必要があった
