The concept of the appliance we describe in this article is based on a number of technological advances. The brackets, created in accordance with CAD/CAM are the product of an original process that makes them resistant to de-bonding providing a high resistance to bracket loss. They are also compatible with the use of a veritable straight wire enabling the use of prefabricated standard wires. The manufacturing process uses a maximum of digitized resources to elaborate a numerical set-up usable by the practitioners. A 3D computerised treatment control is performed from the beginning to the end of the assembly line and warrants a perfect precision of the bonding placement.Appliances are completely personalized for each patient taking into account particular anatomic features as well as the prescriptions of practitioners. As a result practitioners will benefit from a number of theoretical advantages making treatment more pleasant and functionally smoother at every phase of therapy. Managing the Lingualjet appliance is simple and transforms straight wire lingual therapy into a procedure comparable in every way to traditional use of the straight wire in buccally bonded attachments.
我们在本文中描述的设备概念基于许多技术进步。根据CAD/CAM创建的支架是原始工艺的产物,使其具有抗脱粘性,从而提供了高抗支架损失的能力。它们也与使用真正的直线兼容,从而可以使用预制标准线。制造过程使用最大的数字化资源来精心设计一个可供从业人员使用的数字设置。从装配线的开始到结束,都进行了3D计算机化处理控制,确保了粘接位置的完美精度。考虑到特定的解剖特征以及从业人员的处方,器具完全个性化。因此,从业者将受益于一些理论上的优势,使治疗更愉快,在治疗的每个阶段功能更顺畅。管理Lingualjet设备很简单,它将直丝舌治疗转变为一种与传统使用直丝舌粘连附件相当的程序。

Researchers conduct their studies of the mandible by placing it in the “exploitable” framework of systemic biology. They investigate an anomaly of its development, promandibulia, or mandibular prognathism, within this context, by studying molecular and cellular reactions at the level of their constitutive elements and their integration during the course of mandibular development. Here we propose a new etiological and therapeutic approach for this malformation.
研究人员通过将下颌骨置于系统生物学的“可利用”框架中来进行研究。在这种情况下,他们通过研究分子和细胞反应水平上的构成元素及其在下颌发育过程中的整合来研究其发育异常,即下颌前突或下颌前突。在这里,我们提出了一个新的病因和治疗方法的畸形。

Who introduced early treatment to orthodontics 谁介绍了牙齿矫正的早期治疗
Pub Date : 2012-07-01 DOI: 10.1051/ODFEN/2011407
J. Philippe
In the 18th and 19th centuries, dentists ‘‘straightened’’ the teeth of adolescents and adults. Angle had suggested that earlier treatment would be advisable but presented very few examples of this approach. In 1912, E. A. Bogue was the first orthodontist to publish articles advocating treatment for children before they reached the age of six by widening arches to create diastemas between temporary teeth and, above all, by eliminating mouth breathing.
在18世纪和19世纪,牙医“矫正”青少年和成年人的牙齿。安格尔建议早期治疗是可取的,但这种方法的例子很少。1912年,e·a·博格(E. A. Bogue)是第一位发表文章的正畸医生,他提倡对六岁以下儿童进行治疗,通过扩大牙弓,在临时牙齿之间形成间隙,最重要的是,通过消除口腔呼吸。

On the efficiency of two stage treatment for Class II division 1 malocclusions: a retrospective clinical study of 38 cases treated in one or two stages 分两期治疗II类1分错的疗效:38例分两期治疗的回顾性临床研究

Recent evidence based prospective studies, reported by the Revue Cochrane of May 2009, suggest that the best course of action for treatment of Class II, division 1 malocclusions is to await the full eruption of the adolescent dentition and then to install a full banded and bonded appliance because at the end of treatment there is no significant difference between results obtained by a two-stage, orthopedic followed by full fixed appliance, treatment and a onestage only of full banded and bonded therapy. These studies also judge that adding a preliminary orthopedic stage to the therapeutic scheme lengthens total treatment time. In a plea for increased efficiency these authors conclude that two-stage treatment should no longer be employed in contemporary orthodontics. Nevertheless, more and more patients are seeking treatment at orthodontic offices at younger and younger ages, usually when they are between 9 and ten years old and 75% of them, according to Bassigny’s estimate, have Class II malocclusions. Ideally, orthodontists ought to be able to take advantage of this time of growth, often accompanied by change in patients’ dentitions, by instituting early treatment. The average age of patients beginning orthodontic treatment, according to these authors, is
2009年5月的Revue Cochrane报道了最近基于证据的前瞻性研究,建议治疗II类1类错牙合的最佳方案是等待青少年牙列完全出牙,然后安装完整的带状和粘接矫形器,因为在治疗结束时,两阶段矫形器和全固定矫形器所获得的结果没有显著差异。治疗和只有一个阶段的全带状和结合治疗。这些研究还判断,在治疗方案中增加一个初步矫形阶段延长了总治疗时间。在请求提高效率,这些作者得出结论,两阶段的治疗不应再用于当代正畸。然而,越来越多的患者在年龄越来越小的时候到正畸诊所寻求治疗,通常是在9到10岁之间,根据Bassigny的估计,其中75%的人患有II类错颌。理想情况下,正畸医生应该能够利用这段生长时间,通常伴随着患者牙齿的变化,通过建立早期治疗。根据这些作者的说法,患者开始正畸治疗的平均年龄是

J. Faure
We took orthodontic records and began full-banded and bonded treatment soon after F, a 13 year 3 month old girl, who consulted us in 2007 at our office in a city of southwest France. F.’s loss of all four first premolars as an accompaniment to mechano-therapy was compensated for by the eventual successful eruption of her third molars. We were able to remove her appliances in 2009 as we had promised, before her 16th birthday.
2007年,一个13岁3个月大的女孩F在我们位于法国西南部一个城市的办公室向我们咨询后,我们记录了正畸记录,并很快开始了全带和粘接治疗。在机械治疗的过程中,F失去了所有的四颗第一前臼齿,最后第三磨牙的成功长出弥补了这一点。2009年,在她16岁生日之前,我们履行了我们的承诺,搬走了她的电器。

Organization of treatment and orthodontic procedures in cleft lip and palate rehabilitation 唇腭裂康复治疗及正畸程序的组织
Pub Date : 2011-09-01 DOI: 10.1051/ODFEN/2011307

Only competent centres are able to provide the full range of multi-disciplinary specialized therapies that cleft lip and palate rehabilitation requires. Despite some detail differences in conducting treatment, the agreed centres produced consensual treatment philosophy and observe equivalent therapeutic schemes. These sequences, to which orthodontics invariably contributes, are designed to favour the normal outcome of facial development and functions. Beginning early in mixed dentition, orthodontic rehabilitation is designed to afford patients good dental occlusion through orthopaedic and orthodontic therapies. At the end of the growth period, orthodontics prepares for eventual final surgical and prosthetic repair. We avoid extraction of permanent teeth as an adjunct to treatment because it has deleterious effect on final skeletal harmony. We prefer basic appliances for mechanical therapy, and after completion of active treatment, a prolonged retention. A trained orthodontist is able to complete the orthopaedic and orthodontic stages in cleft lip and palate repair if he fully understands and follows the general cleft lip and palate treatment scheme and effectively communicates with the competent rehabilitation team.
只有有能力的中心才能提供唇腭裂康复所需的全方位多学科专业治疗。尽管在进行治疗方面有一些细节上的差异,但商定的中心提出了双方同意的治疗理念,并遵守相同的治疗方案。这些序列,其中正畸总是有助于,旨在有利于面部发育和功能的正常结果。从混合牙列早期开始,正畸康复旨在通过矫形和正畸治疗为患者提供良好的牙齿咬合。在生长末期,正畸学为最终的手术和义肢修复做准备。我们避免拔恒牙作为治疗的辅助手段,因为它对最终的骨骼和谐有有害的影响。我们倾向于使用基本的器械进行机械治疗,在完成积极的治疗后,延长保留时间。一名训练有素的正畸医师如果完全理解并遵循一般的唇腭裂治疗方案,并与有能力的康复团队进行有效的沟通,就能够完成唇腭裂修复的矫形和正畸阶段。

Parents want their children’s’ faces, the most visible part of their bodies, one that marks their identity throughout life, to be perfect. To satisfy this understandably urgent desire, a high quality of primary treatment for cleft lip and palate is essential and must satisfy a double objective: restore normal morphology and normal function. The functional, morphological, and esthetic prognoses depend on the character of the defect, whether it stands alone or is associated in a syndrome with other malformations. Important sequellae flow from the quality of the initial repair, as a consequence of the surgery and other therapies as well as from the deformity itself.Before the year 2000, the Maxillo-facial and Plastic Surgery Service at the Armand Trousseau Hospital of the Pierre and Marie Curie Faculty of Medicine adhered to the protocol that Malek had described, making an initial repair of the soft palate at 3 months and then a cheiloplasty, with upper and lower triangles, and closure of the hard palate at 6 months. Since then we have adopted the more functional approach that Talmant described, integrating systematic nasal surgery and the type of lip surgery that Millard suggested without leaving any residual exposed bone after closure of the osseous cleft. We then perform gingivo-periosteal surgery with bone grafts on patients when they were between 4 and 6 years of age, after orthodontic therapy had been completed. This constitutes the last stage of primary treatment.The therapeutic approach we have been using on our service, which has evolved of over the last 20 years, has come to define its principal objective as integration of extensive rehabilitation into the very first stages of our multi-disciplinary therapy so as to minimize the establishment of faulty functioning of phonation, lip competence, and ventilation while avoiding any intervention that would have a harmful impact on facial growth. This multi-disciplinary approach, which integrates surgical evaluation and protocol, is indispensable and fully justifies treatment of patients with cleft lip and palate at accredited centers.
父母希望孩子的脸是完美的,因为脸是孩子身体最显眼的部分,标志着他们一生的身份。为了满足这一迫切的需求,高质量的唇腭裂初级治疗是必不可少的,必须满足双重目标:恢复正常形态和正常功能。功能、形态学和美学预后取决于缺陷的特征,无论它是单独存在还是与其他畸形相关联。重要的后遗症来自最初修复的质量,作为手术和其他治疗的结果以及畸形本身。2000年之前,皮埃尔和玛丽居里医学院的Armand Trousseau医院的颌面和整形外科服务部门遵循了Malek所描述的方案,在3个月时对软腭进行初步修复,然后进行上三角形和下三角形的唇部成形术,并在6个月时关闭硬腭。从那时起,我们采用了Talmant描述的更功能的方法,将系统的鼻手术和Millard建议的唇手术结合起来,在骨裂闭合后不留下任何残留的暴露骨。然后,我们对4至6岁的患者在完成正畸治疗后进行牙龈-骨膜移植手术。这是初级治疗的最后阶段。在过去的20年里,我们一直在使用的治疗方法已经发展起来,我们已经将其主要目标定义为将广泛的康复整合到我们多学科治疗的第一阶段,以最大限度地减少发声,嘴唇能力和呼吸功能的错误,同时避免任何可能对面部生长产生有害影响的干预。这种多学科的方法,整合了手术评估和协议,是必不可少的,充分证明了在认可的中心治疗唇腭裂患者。

The designation labio-maxillo-palatal cleft is used to describe two types of congenital malformations of the palate. The mechanisms that create them occur in the early weeks of fetal life by an alteration of embryological message delivery that researchers have been able to analyze. But they have not as yet been able to discern the multi-factorial causes of this alteration. Morphological embryology and its chronology are important because researchers use an understanding of them to distinguish between different entities of clefts on the basis of the stage of palatal formation in which they began to develop: the numerous molecules involved In cell development are already well known, but researchers have not yet precisely identified those that are associated with the various stages of palatal morphogenesis. But it is clear that genetic alterations, which are now being pin-pointed, trigger developmental malfunctionings that are later intensified by faulty interactions in the fetalmaternal environment because. Conclusion: Although researchers are progressively gaining a better understanding of the mechanisms of the intra-uterine formation of labiomaxillo-palatal clefts, we have not yet acquired the broad range of data that would make it possible to correct defective palatal formation before birth.
唇腭裂的名称是用来描述两种类型的先天性腭畸形。研究人员已经能够分析,在胎儿生命的最初几周,通过胚胎学信息传递的改变,产生它们的机制发生了变化。但是他们还没有能够辨别出这种变化的多因素原因。形态学胚胎学及其年代学是很重要的,因为研究人员利用对它们的理解,根据它们开始发育的腭形成阶段来区分不同的裂隙实体:参与细胞发育的众多分子已经为人所知,但研究人员尚未精确地确定那些与腭形态发生的各个阶段相关的分子。但很明显的是,基因的改变,现在已经被明确指出,会引发发育障碍,而这些障碍后来会因胎儿母体环境中的错误相互作用而加剧,因为。结论:尽管研究人员对唇腭裂子宫内形成的机制有了更好的了解,但我们还没有获得广泛的数据,可以在出生前纠正有缺陷的腭形成。

Variation in centric relation in the conscious and the anesthetized patient 清醒与麻醉患者中心关系的变异
Pub Date : 2011-09-01 DOI: 10.1051/ODFEN/2011309
C. Jolivet
Every practitioner undertaking a case of dental rehabilitation has as one of the major goals of successful treatment making the patients’ centric occlusions coincide with their occlusion of maximum inter-cuspation in order to assure that their masticatory apparatus will function harmoniously. Specialists in dentofacial orthopedics, while always aiming at improving facial esthetics, enshrine the re-establishment of good masticatory functioning as an essential goal and to do this they must respect the fundamental principles of occlusion. Some serious skeletal deformities that cannot be completely resolved by dentofacial orthopedics alone require surgical intervention. These orthognathic procedures should be designed to achieve the same occlusal objectives of establishing skeletal and facial equilibrium with dentitions in normal Class I Angle occlusion and the condylar heads seated correctly in the mandibular fossas. This means that the orthodontist dealing with conscious patients and maxillo-facial surgeons operating on the same individuals when they are anesthetized will seek the same mandibulo-cranial relationship, the reference articulation, or centric relation. Because general anesthesia causes complete neural relaxation of the muscles that are an important element controlling centric relation surgeons need to know if it modifies this articular reference position. If it does, surgeons then have to know what, if any, adjustments they should make in response. In order to answer these questions we established an experimental protocol to compare the centric relation of the conscious patient (CR) to the centric relation of the same patient when anesthetized (CR 2).
每个从事牙科康复的医生都有一个成功治疗的主要目标,使患者的中心咬合与他们的最大咬合吻合,以确保他们的咀嚼器官和谐地运作。牙面矫形外科的专家,虽然总是以改善面部美学为目标,但将重建良好的咀嚼功能作为一个基本目标,为此,他们必须尊重咬合的基本原则。一些严重的骨骼畸形不能完全解决牙面矫形单独需要手术干预。这些正颌手术的设计应达到相同的咬合目标,即在正常的I类角咬合中,与牙列建立骨骼和面部平衡,并使髁头正确地坐在下颌窝中。这意味着处理清醒病人的正畸医生和对同一个人进行麻醉手术的颌面外科医生将寻求相同的下颌-颅关系、参考关节或中心关系。由于全身麻醉导致肌肉神经完全松弛,这是控制中心关系的重要因素,外科医生需要知道它是否改变了关节的参考位置。如果确实如此,外科医生就必须知道,如果有的话,他们应该做出什么调整来应对。为了回答这些问题,我们建立了一个实验方案来比较意识病人的中心关系(CR)和同一病人在麻醉时的中心关系(cr2)。

Specialists in dentofacial orthopedics, while always aiming at improving facial esthetics, enshrine the re-establishment of good masticatory functioning as an essential goal and to do this they must respect the fundamental principles of occlusion. Some serious skeletal deformities that cannot be completely resolved by dentofacial orthopedics alone require surgical intervention. These orthognathic procedures should be designed to achieve the same occlusal objectives of establishing skeletal and facial equilibrium with dentitions in normal Class I Angle occlusion and the condylar heads seated correctly in the mandibular fossas.
