    Introduction: Our objective was to elucidate the differences in treatment outcomes caused by the different mechanics of temporary anchorage devices (TADs) and Class III elastics in patients with Class III malocclusions. Methods: Records of 23 patients with Angle Class III malocclusion were selected retrospectively. All had been treated with nonextraction comprehensive orthodontic treatment; 11 were treated with TADs and 12 with Class III elastics. Pretreatment and posttreatment lateral cephalograms were used for evaluation of the treatment outcomes. A paired t test and a Student t test were used for statistical analysis. Results: In both groups, proper overjet and Class I molar relationships were achieved, and the occlusal plane was rotated counterclockwise. In the elastics group, distal tipping of the mandibular molars, extrusion of the mandibular incisors and maxillary molars, clockwise rotation of the mandibular plane angle, and increased ANB angle were observed. In the TADs group, distal tipping and intrusion of the mandibular molars, bodily movement of the mandibular incisors, and reduced mandibular plane angle were observed. Conclusions: In nonextraction treatment for Class III malocclusions, the mandibular plane angle was increased in the elastics group, whereas it was decreased in TADs group. Thus, we suggest that Class III elastics are preferred for low-angle, short-face patients, whereas TADs are preferred for high-angle, long-face patients.

    INTRODUCTION: In recent years, patients with orthognathic surgery in middle-aged and elderly people have come to be a more frequent occurrence. Breast cancer is the most frequently diagnosed cancer in woman worldwide, and its prevalence rate is steadily increasing. PRESENTATION OF CASE: We report a case of a 47-year-old Japanese woman in whom left-side breast cancer (Stage 1) was unexpectedly found just before orthognathic surgery in April 2012. Breast-conserving surgery was performed (estrogen receptor+, progesterone receptor+, HER2 -, surgical margin+, sentinel lymph node +) that May. From June to August docetaxel (75mg/m2) and cyclophosphamide (600mg/m2) were administrated four times every 21days and thereafter radiotherapy (total 60Gy) was completed. The cancer surgeon declared the prognosis good and the patient had a strong desire to undergo orthognathic surgery, so in November we performed a bimaxillary osteotomy, and administration of tamoxifen began 6 weeks after the osteotomy. DISCUSSION: There are breast cancer cases in which the prognosis is sufficiently good for a planned orthognathic surgery to proceed. Good communication among surgeons and the patient is important. CONCLUSION: We experienced a case in which breast cancer was found just before the orthognathic surgery; we performed a bimaxillary osteotomy, including follow-up tamoxifen administration, during breast cancer treatment.

    上下顎前突の治療では上下顎切歯の舌側移動量が大きいため、上下顎切歯の挺出やそれに伴う下顎の時計回りの回転など垂直的な問題が生じやすい。本症例では、垂直的な問題が認められない上下顎前突の治療において、良好な結果が得られたので報告する。患者は初診時年齢23歳2ヵ月の女性で、前歯が出ていることと口元が出ていることを主訴に来院した。正貌は左右対称、側貌は凸顔型であり、上下唇の突出と口唇閉鎖不全が認められた。骨格系では、前後的には骨格性I級であり、垂直的には下顎骨の位置は標準的であった。歯系では、上下顎歯列軽度叢生、水平的には下顎歯列正中の右方偏位、前後的には大臼歯関係は両側Angle I級、オーバージェットは4.0mm、上下顎中切歯の唇側傾斜が認められ、垂直的にはオーバーバイトは0.5mmであった。以上より、上下顎歯列軽度叢生および下顎歯列正中の右方偏位を伴う骨格性I級、Angle I級、歯性上下顎前突症例と診断された。下顎の時計回りの回転を生じさせずに上下顎前歯を舌側移動させるために、歯科矯正用アンカースクリューとスライディングメカニクスを用いるエッジワイズ法で上下顎両側第二小臼歯を抜去して治療を行った。その結果、下顎の時計回りの回転を生じさせずに、上下顎中切歯をおおむね治療目標通りの位置へ移動させることができた。これより、上下顎前突の治療においても、前後的な歯の移動だけでなく垂直的な歯性および骨格性の変化も考慮した抜歯部位や治療機序の決定が重要であることが示唆された。(著者抄録)

    We report a case involving a young female patient with severe mandibular retrognathism accompanied by mandibular condylar deformity that was effectively treated with Le Fort I osteotomy and two genioplasty procedures. At 9 years and 9 months of age, she was diagnosed with Angle Class III malocclusion, a skeletal Class II jaw relationship, an anterior crossbite, congenital absence of some teeth, and a left-sided cleft lip and palate. Although the anterior crossbite and narrow maxillary arch were corrected by interceptive orthodontic treatment, severe mandibular hypogrowth resulted in unexpectedly severe mandibular retrognathism after growth completion. Moreover, bilateral condylar deformities were observed, and we suspected progressive condylar resorption (PCR). There was a high risk of further condylar resorption with mandibular advancement surgery;. therefore, Le Fort I osteotomy with two genioplasty procedures was performed to achieve counterclockwise rotation of the mandible and avoid ingravescence of the condylar deformities. The total duration of active treatment was 42 months. The maxilla was impacted by 7.0 mm and 5.0 mm in the incisor and molar regions, respectively, while the pogonion was advanced by 18.0 mm. This significantly resolved both skeletal disharmony and malocclusion. Furthermore, the hyoid bone was advanced, the pharyngeal airway space was increased, and the morphology of the mandibular condyle was maintained. At the 30-month follow-up examination, the patient exhibited a satisfactory facial profile. The findings from our case suggest that severe mandibular retrognathism with condylar deformities can be effectively treated without surgical mandibular advancement, thus decreasing the risk of PCR.

    Introduction: The intercellular network of cell-cell communication among osteocytes is mediated by gap junctions. Gap junctional intercellular communication (GJIC) is thought to play an important role in the integration and synchronization of bone remodeling. To further understand the mechanism of bone development it is important to quantify the difference in the GJIC capacity of young and developmentally mature osteocytes.
    Materials and methods: We first established an embryonic chick calvaria growth model to show the growth of the calvaria in embryos at 13 to 21 days of age. We then applied a fluorescence recovery after photobleaching (FRAP) technique to compare the difference in the GJIC capacity of young osteocytes with that of developmentally mature osteocytes. Finally, we quantified the dye (Calcein) diffusion from the FRAP data using a mathematic model of simple diffusion which was also used to identify simple diffusion GJIC pattern cells (fitted model) and accelerated diffusion GJIC pattern cells (non-fitted model).
    Results: The relationship between the longest medial-lateral length of the calvaria (frontal bone) and the embryonic age fit a logarithmic growth model: length = 5.144 x ln(day) - 11.340. The morphometric data during osteocyte differentiation showed that the cellular body becomes more spindle-shaped and that the cell body volume decreased by approximately 22% with an increase in the length of the processes between the cells. However, there were no significant differences in the cellular body surface area or in the distance between the mass centres of the cells. The dye-displacement rate in young osteocytes was significantly higher than that in developmentally mature osteocytes: dye displacement only occurred in 26.88% of the developmentally mature osteocytes, while it occurred in 64.38% of the young osteocytes. Additionally, in all recovered osteocytes, 36% of the developmentally mature osteocytes comprised non-fitted model cells while 53.19% of the young osteocytes were the non-fitted model, which indicates the active transduction of dye molecules. However, there were no statistically significant differences between the young and developmentally mature osteocytes with regard to the diffusion coefficient, permeability coefficient, or permeance of the osteocyte processes, which were 3.93 +/- 3.77 (x 10(-8) cm(2)/s), 5.12 +/- 4.56 (x 10(-8) cm(2)/s) and 2.99 +/- 2.47 (x 10(-13) cm(2)/s) (mean SD), respectively.
    Conclusions: These experiments comprehensively quantified the GJIC capacity in the embryonic chick calvaria and indicated that the cell-cell communication capacity of the osteocytes in the embryonic chick calvaria was related to their development. (C) 2016 Elsevier Inc. All rights reserved.

    患者は20歳6ヵ月の女性で、上顎前歯部の叢生および前歯部開咬を主訴に岡山大学病院矯正歯科を受診した。側貌は凸型、オトガイの後退感、口唇閉鎖不全が認められた。両側アングルI級、前歯部開咬を呈し、上下顎前歯はやや唇側傾斜していた。さらに、予後不良な下顎左側第一大臼歯、上下顎歯列の叢生、軽度の咬合平面の二面性が認められた。分析の結果、上下顎前歯部叢生を伴う骨格性II級、ハイアングル、ロングフェイス、前歯部開咬症例と診断された。予後不良歯である下顎左側第一大臼歯に加え下顎右側第一大臼歯及び上顎両側第一小臼歯の抜歯を伴うカモフラージュ治療を行うこととなった。下顎両側第二・第三大臼歯の近心移動およびスピー彎曲の改善に伴い下顎臼歯の挺出が生じ、下顎骨の時計回り回転が危惧されたため、下顎骨回転に伴う側貌の悪化を防ぐことを目的に上顎両側大臼歯の圧下を行うこととした。動的治療期間は4年5ヵ月であった。オトガイの後退感は残るものの口元の突出感は改善し良好な側貌を獲得した。治療前後の重ね合わせでは、上下顎前歯歯軸および臼歯移動量は治療目標設定値と近似しており、下顎下縁平面角は維持されていた。保定2年が経過したが、咬合は安定している。長期予後不良な第一大臼歯を認める場合、下顎第一大臼歯抜歯による下顎第二・第三大臼歯の近心移動は有用な治療法であるが、ハイアングル・ロングフェイス症例においては、下顎大臼歯の挺出による顔貌の悪化を防ぐため上顎大臼歯の圧下を行うことが望ましいと考える。(著者抄録)

    This case report describes a novel method of combining lingual appliances and lingual arches to control horizontal problems. The patient, who was 25 years of age at her first visit to our hospital with a chief complaint of crooked anterior teeth, was diagnosed with skeletal Class II and Angle Class II malocclusion with anterior deep bite, lateral open bite, premolar crossbite, and severe crowding in both arches. She was treated with premolar extractions and temporary anchorage devices. Conventionally, it is ideal to use labial brackets simultaneously with appliances, such as a lingual arch, a quad-helix, or a rapid expansion appliance, in patients with complex problems requiring horizontal, anteroposterior, and vertical control; however, this patient strongly requested orthodontic treatment with lingual appliances. A limitation of lingual appliances is that they cannot be used with other conventional appliances. In this report, we present the successful orthodontic treatment of a complex problem using modified lingual appliances that enabled combined use of a conventional lingual arch.

    Rodent incisors grow continuously throughout life, and epithelial progenitor cells are supplied from stem cells in the cervical loop. We report that epithelial Runx genes are involved in the maintenance of epithelial stem cells and their subsequent continuous differentiation and therefore growth of the incisors. Core binding factor beta (Cbfb) acts as a binding partner for all Runx proteins, and targeted inactivation of this molecule abrogates the activity of all Runx complexes. Mice deficient in epithelial Cbfb produce short incisors and display marked underdevelopment of the cervical loop and suppressed epithelial Fgf9 expression and mesenchymal Fgf3 and Fgf10 expression in the cervical loop. In culture, FGF9 protein rescues these phenotypes. These findings indicate that epithelial Runx functions to maintain epithelial stem cells and that Fgf9 may be a target gene of Runx signaling. Cbfb mutants also lack enamel formation and display downregulated Shh mRNA expression in cells differentiating into ameloblasts. Furthermore, Fgf9 deficiency results in a proximal shift of the Shh expressing cell population and ectopic FGF9 protein suppresses Shh expression. These findings indicate that Shh as well as Fgf9 expression is maintained by Runx/Cbfb but that Fgf9 antagonizes Shh expression. The present results provide the first genetic evidence that Runx/Cbfb genes function in the maintenance of stem cells in developing incisors by activating Fgf signaling loops between the epithelium and mesenchyme. In addition, Runx genes also orchestrate continuous proliferation and differentiation by maintaining the expression of Fgf9 and Shh mRNA. STEM CELLS 2011;29:1792-1803

    当大学の歯科矯正学分野において、「歯の移動の臨床手技実習」における60分授業・クォーター制を導入し、導入前後の年度で学生と教職員にアンケートを実施した。学生アンケートでは、導入前の平成27年度の実習受講生53名と導入後の平成28年度の受講生46名を対象とした。教職員アンケートでは、平成28年度の実習で指導にあたった教職員7名と補助した医局員20名を対象とした。その結果、導入後では実習内容、指導法、実習書といった教育コンテンツの改善により学生の自修意欲が高まり、一定の成果を上げることができていた。また、ICTを活用した授業支援システム"WebClass"も予習・復習に積極的に利用されており、成果に貢献していた。しかし、実習時間の短縮への対応の点では問題が残り、「時間不足」を訴える意見が多く聞かれた。

    It is speculated that cell homeostasis is reduced because osteoblasts on the surface of the bone matrix are exposed to various pathological conditions when orthodontic force is applied to teeth. However, details of molecular mechanism for maintaining homeostasis is still unclear. As a result of this study, it was confirmed that osteoblasts on the surface of the alveolar bone during orthodontic tooth movement were in a hypoxic state and were exposed to endoplasmic reticulum stress. In addition, the expression of autophagy markers at the same site was also confirmed, and it was also confirmed that in culture osteoblasts, autophagy was enhanced with respect to hypoxic stress. These findings suggest that autophagy may be involved in maintaining cell homeostasis in osteoblasts exposed to hypoxic and endoplasmic reticulum stress during orthodontic tooth movement.

    In the present study, we investigated if the new pain mechanism with Transient Receptor Potential (TRP) channel exist at experimental orthodontic tooth movement. There were TRPV2, TRPC1 and C6 in the periodontal ligament (PDL) tissues compared with the pulp tissues. The TRPV2-positive free nerve endings were observed in the PDL. Moreover, c-fos-positive cell were decreased at trigeminal subnucleus caudalis by the antagonist to the TRPV2. From the above, it is suggested that TRPV2 channel is concerned in the pain stimulus reception at orthodontic tooth movement.
