In December 2004, Myriam H. was almost 16 years old. The appliances used for her full-banded orthodontic treatment had been removed a few months earlier and she consulted our clinic because of a complete recurrence of anterior crowding. She had brought along the X-rays that were taken for the extraction of her four un-erupted wisdom teeth the previous month. Unfortunately, these extractions could not and did not do anything to improve the crowding which occurred as soon as the appliances were removed. She was determined to undertake a re-treatment procedure. We carefully explained to her how hard it would be to correct all the over-lapped incisor teeth and the remaining bi-maxillary protrusion that persisted even though four premolars and four third molars had been extracted in a treatment program that lacked adequate anchorage preparation and precautions. Clearly we were not being asked to correct a minor imperfection but to undertake the difficult complete re-treatment of a malocclusion that was now more severe than it had been originally. But Myriam was undeterred.
2004年12月,米利亚姆·h快要16岁了。几个月前,她使用的全带正畸治疗器械已经被移除,因为前牙拥挤的完全复发,她咨询了我们的诊所。她带来了上个月拔四颗未长出的智齿时拍的x光片。不幸的是,这些拔除措施不能也没有改善拔除器械后立即出现的拥挤状况。她决定再接受一次治疗。我们仔细地向她解释了矫正所有重叠的门牙和残留的双上颌突出是多么困难,即使在缺乏足够的固定准备和预防措施的治疗方案中,已经拔出了四颗前磨牙和四颗第三磨牙。很明显,我们不是被要求纠正一个小的缺陷,而是承担一个比原来更严重的错的困难的完全再治疗。但是米里亚姆没有被吓倒。

Benefits of three-dimensional imaging 三维成像的好处
Pub Date : 2010-03-01 DOI: 10.1051/ODFEN/2010107
O. Sorel, A. Ollivier, Marie-Charlotte Mano
Three dimensional images derived from X-Rays, scans or Digital Cone Beam Computed Tomography (CBCT) are components of supplementary diagnostic procedures. Using them, practitioners can visualize the anatomic relationships of teeth with each other and with adjacent structures and can discern the presence or absence of root resorption.These radiographic films can assist in the diagnostic evaluation of impacted, transposed, or duplicated teeth or those situated on the edges of facial clefts. They are indispensable in helping diagnosticians to rule out contraindications as they establish treatment plans and continue to be useful as guides when mechano- therapy starts.Recently, CBCT has become accessible for use in dental offices even though it has been an expensive and bulky instrument with a relatively high radiation output. Today, with a more acceptable radiation dosage, it is well accepted as an alternative diagnostic procedure in the field of oro-facial implants, but overall, it cannot yet be considered as a technique that should be systematically employed in every supplementary examination.
来自x射线、扫描或数字锥束计算机断层扫描(CBCT)的三维图像是辅助诊断程序的组成部分。使用它们,从业者可以可视化牙齿之间以及与相邻结构之间的解剖关系,并可以辨别牙根吸收的存在或不存在。这些x线片可以帮助诊断评估埋伏,转位,或重复的牙齿或那些位于面部唇裂的边缘。它们在帮助诊断医师在制定治疗计划时排除禁忌症方面是不可或缺的,并在机械治疗开始时继续作为有用的指导。最近,CBCT已经可以在牙科诊所使用,尽管它是一种昂贵且体积庞大的仪器,辐射输出相对较高。今天,由于放射剂量更易于接受,它被广泛接受为口腔-面部植入领域的一种替代诊断程序,但总的来说,它还不能被认为是一种应该系统地应用于每一次补充检查的技术。

The human canine: Its evolution and adaptive significance 人类犬科动物的进化及其适应意义
Pub Date : 2010-03-01 DOI: 10.1051/odfen/2010103
P. Picq
The canine is a tooth with special characteristics and adaptive significance that varies considerably between mammalian lines and the primates. No matter what the line, canine teeth are never involved in mastication and do not interfere with masticatory dynamics. Mastication, which is one of the most complex functions that monkeys and apes display, appears well before the large canines in both phylogeny and ontogeny. In apes, their size and shape have nothing to do with diet, but are linked to sexual selection. The human line of hominids possesses smaller canines that have become incisiform and have lost their sexual and social function. They are now used exclusively to tear apart meat and other types of solid foods. The development of a wide, short buccal surface that increased medial-lateral movement during the masticatory cycle, may explain this particular development in recent hominids including humans. From an evolutionary point of view this means that the human canine has been subjected to stresses imposed by the biomechanical environment of the masticatory apparatus. In other words, the human canine, as well as those of the other anthropoids, does not guide mastication but has acquired a morphology and position restricted by masticatory functions. In evolutionary terms, it is therefore referred to as an “exaptation”; it has acquired, not a function, but a passive characteristic which makes it a marker for rehabilitation – on condition that its eruption is related to normal masticatory functions in individual histories, but it never serves as a mediator of mastication.
犬齿是一种具有特殊特征和适应意义的牙齿,在哺乳动物和灵长类动物之间差异很大。无论什么线,犬齿从不参与咀嚼,不干扰咀嚼动力学。咀嚼是猴子和类人猿表现出的最复杂的功能之一,在系统发育和个体发育上都远远早于大型犬科动物。在类人猿中,它们的大小和形状与饮食无关,但与性选择有关。人类原始人拥有更小的犬齿,这些犬齿已经变得锋利,失去了性和社会功能。它们现在专门用于撕裂肉类和其他类型的固体食物。宽而短的颊面在咀嚼周期中增加了内侧侧向运动,这可能解释了包括人类在内的近代原始人的这种特殊发展。从进化的角度来看,这意味着人类犬类受到了咀嚼器官的生物力学环境所施加的压力。换句话说,人类犬科动物和其他类人猿一样,并不指导咀嚼,而是获得了一种受咀嚼功能限制的形态和位置。因此,从进化的角度来看,它被称为“灭绝”;它已经获得了,不是一种功能,而是一种被动的特征,这使它成为康复的标志——在它的爆发与个体历史上正常的咀嚼功能有关的条件下,但它从来没有作为咀嚼的中介。

Angle decided that the word ''irregularity'' employed in the 19 th century was inappropriate. He proposed the term ''malocclusion'', which the French for a long time denigrated only to begin to employ it recently. But beneath new vocables new concepts are hidden.
“正畸”这个词。1841年,Lefoulon提出了“orthodontosie”一词,美国人将其简化为“orthodontia”,后来又简化为“orthodontics”。但是法国人拒绝了。“骨科”和“正畸学”之间的长期斗争开始了,2007年,“正畸学”结束了。“我们休战了吗?”2 -“错牙合”这个词。安格尔认为19世纪使用的“不规则”一词是不恰当的。他提出了“错颌畸形”一词,法国人长期以来一直诋毁这个词,直到最近才开始使用。但在新词汇的背后隐藏着新概念。

What has happened to the old time fundamentals 过去的基本面发生了什么变化
Pub Date : 2009-12-01 DOI: 10.1051/odfen/2009401
P. Planché
Once upon a time in the good old days charming young girls who wanted to get their teeth straightened willingly agreed to wear a head cap for days and months on end and to have a metal arch wire with two gross elastics attached to it installed their mouths. The goal of this unsightly burden, orthodontists explained to them, was to move their upper first molars back far enough to make room in their dental arches for all the other teeth to be evenly aligned. Thirty years later, we seem to have decided that it is impossible, or inadvisable, to distalize the maxillary molars past the pterygoid processes with the aid of “EOF” or of that other device called “The Pendulum. ” Why did it take us so long to discover the inefficacy of this procedure? The Dutch and the Japanese have, notably, for years followed the Begg technique which postulates the immediate removing not moving of two upper molars. As the years go by we never see a patient wearing an EOF appliance. What’s happened? What has happened is that a new generation of adolescents is no longer willing to put up with those old fashioned techniques. Adolescence is a period when the body changes, when the dentition changes, and when boys and girls begin to wonder about their futures. They don’t want to follow slavishly in their parents’ footsteps and they certainly don’t want to be “controlled” by adults or even by their peers. This new generation has discovered sexuality much earlier than their elders did and they are easily tempted by the siren call of the consumption society. Realizing all this, we have, a little late, replaced the uncool head gear with intra oral elastics which have had only a limited success, owing to the sad reality that they only work when patients wear them. So orthodontists have adjusted their methods, finding alternative sources of anchorage respecting as much as possible their patients’ strong desire to keep their braces invisible to public E D I T O R I A L
从前,在那美好的旧日时光里,迷人的年轻姑娘们想要矫正牙齿,她们愿意一连几天或几个月戴一顶帽子,并在嘴里装上一根金属弓丝,上面连着两根粗大的橡皮筋。正畸医生向他们解释说,这个难看的负担的目的是将他们的第一磨牙向后移动足够远,以便在牙弓中腾出空间,让所有其他牙齿均匀排列。三十年后,我们似乎已经决定,借助“EOF”或另一种称为“钟摆”的装置,将上颌磨牙远距到翼状突以上是不可能的,或者说不可取的。为什么我们花了这么长时间才发现这个程序的无效?值得注意的是,荷兰人和日本人多年来一直采用贝格技术,该技术要求立即移除两颗上磨牙而不移动。随着时间的流逝,我们从来没有见过一个病人戴着EOF器械。发生了什么事?所发生的事情是,新一代的青少年不再愿意忍受那些老式的技术。青春期是身体发生变化的时期,是牙齿发生变化的时期,是男孩和女孩开始对自己的未来感到好奇的时期。他们不想盲目地跟随父母的脚步,他们当然也不想被成年人甚至同龄人“控制”。新一代人比他们的长辈更早地发现了性,他们很容易被消费社会的诱惑所诱惑。意识到这一切,我们已经,有点晚了,用口腔内的弹性代替了不酷的头套,这只取得了有限的成功,因为可悲的现实是,它们只有在病人戴上它们时才有效。因此,正畸医生调整了他们的方法,尽可能地尊重病人不让他们的牙套暴露在公众面前的强烈愿望,寻找替代的锚定来源

How to make an informed choice of the right laser 如何明智地选择合适的激光器
Pub Date : 2009-12-01 DOI: 10.1051/ODFEN/2009404
Jacques Berrebi
There has been a considerable increase in the clinical use of lasers in dentistry over the past thirty years, especially in orthodontics. But clinicians who have not yet made their decisions about participating in this technological revolution can be perplexed by the great variety of wave lengths available, the vast number of machines that can be used to employ them, and the complexity of the principles of physics upon which lasers beams are based. The objective of this article is to give practitioners a better understanding of the indications for the use of the various types of lasers.
在过去的三十年里,激光在牙科的临床应用有了相当大的增加,特别是在牙齿正畸方面。但是,尚未决定是否参与这场技术革命的临床医生可能会被可供选择的各种波长、可用于使用它们的大量机器以及激光光束所依据的物理原理的复杂性所困扰。本文的目的是让从业者更好地了解使用各种类型的激光的适应症。

A myofunctional approach to treatment of anterior cross bites 肌功能入路治疗前交叉咬伤
Pub Date : 2009-12-01 DOI: 10.1051/ODFEN/2009409
P. Amat
A cross bite of one or more anterior teeth can interfere with the function of the incisocanine block in guiding mandibular escursive and protrusive movements out of a position of occlusion. When this type of malocclusion occurs without any associated skeletal imbalance, orthodontists can correct it with relative ease by using a variety of well-documented appliances. The objective of this article is to describe a myofunctional approach for dealing with this problem. In it, the orthodontist first removes the cross bite’s blockage of tooth movement by placing glass-ionomer cement blocks on the occlusal surfaces of posterior teeth. When this is done the tongue, labial, and cheek musculature can accomplish their role, without inhibition, of correcting positions of the dentoalveolar arches in two or three months.
一颗或多颗前牙的交叉咬合会干扰切辛酸块引导下颌移出咬合位置的功能。当这种类型的错牙合发生时,没有任何相关的骨骼失衡,正畸医生可以通过使用各种记录良好的器具相对容易地纠正它。本文的目的是描述处理此问题的一种函数式方法。在这种方法中,正畸医生首先通过在后牙的咬合面上放置玻璃离子水泥块来去除交叉咬合对牙齿运动的阻碍。这样做后,舌头、唇和脸颊肌肉组织可以在两到三个月内完成它们的作用,不受抑制地纠正牙槽弓的位置。

Aesthetic assessment of a facial profile according to mandibular position 根据下颌位置对面部轮廓的美学评价
Pub Date : 2009-12-01 DOI: 10.1051/ODFEN/2009406

The relevance of this paper consists in comparing the practitioner’s view to general public opinion. Orthodontists learned to evaluate facial profiles in a critical way, with reference to standards. They have developed personal appreciations to gauge a balanced profile. But, because orthodontic treatment implies achieving an aesthetic effect, the practitioner must know what is the optimal objective according to the public opinion. Our study deals with the aesthetic assessment of teenagers’ profiles in Class II (Corner and Ballard) by professional examiners and lay people. These profiles have been modified by simulating mandibular protrusion.
本文的相关性在于将从业者的观点与公众舆论进行比较。正畸医生学会了参照标准,以一种批判性的方式评估面部轮廓。他们已经发展出个人的鉴赏力来衡量一个平衡的形象。但是,由于正畸治疗意味着达到审美效果,从业者必须根据民意了解什么是最佳目标。本研究探讨了专业审查员和外行人对二年级(Corner和Ballard)青少年侧面的审美评价。这些轮廓已被修改模拟下颌突出。

These profiles have been modified by simulating mandibular protrusion.","PeriodicalId":381766,"journal":{"name":"Journal of Dentofacial Anomalies and Orthodontics","volume":"59 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132400454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

P. Amat, Jacques Berrebi, F. Hervé
Philippe AMAT, Jacques BERREBI, Franck HERVE. Professor Sam Nammour, you are the director of the European Masters Degree in Oral Laser Applications program. Because of your contributions to it, all its participants have awarded you with a bronze star prize. This honor presented within the framework of the European Life-Long Education and Training program, reflects the recognition throughout the continent of 3 cycle diplomas for dentists. Can you tell us about the modalities and objectives of this program? Samir NAMMOUR. The three universities of Nice, in France, of Aix-la-Chapelle in Germany, and Liege in Belgium, have, independently, been offering courses in the use of lasers in dentistry since the year 2000. Then one day we began to wonder why we should all be working, isolated, in our private academic fief-doms? Why couldn’t we pool our resources and present a single, more comprehensive, unified course? We presented this border breaching concept to the European Community, asking that the three universities be authorized to offer a common diploma to be called the European Masters Degree in Oral Laser Applications, (EMDOLA). After two years of joint teaching experience, we were delighted to learn that the European Community was ready to grant final acceptance of our project. We hope to continue offering the highest quality instruction that would unite the best potentials developed in each of the three participating institutions.
Philippe AMAT, Jacques BERREBI, Franck HERVE。Sam Nammour教授,你是欧洲口腔激光应用硕士项目的主任。由于你的贡献,所有参与者都授予你铜星奖。这一荣誉是在欧洲终身教育和培训计划的框架内提出的,反映了整个大陆对牙医3个周期文凭的认可。你能告诉我们这个项目的模式和目标吗?萨米尔NAMMOUR。自2000年以来,法国尼斯大学、德国艾克斯-拉-夏贝尔大学和比利时列日大学分别开设了在牙科中使用激光的课程。后来有一天,我们开始纳闷,为什么我们都要在自己的学术领地里与世隔绝地工作?为什么我们不能集中我们的资源,提供一个单一的,更全面的,统一的课程?我们向欧洲共同体提出了这个突破边界的概念,要求授权这三所大学提供一个共同的文凭,称为欧洲口腔激光应用硕士学位(EMDOLA)。经过两年的联合教学经验,我们很高兴得知欧共体准备最终接受我们的项目。我们希望继续提供最高质量的教学,将三个参与机构的最佳潜力结合起来。
