Today, many people receive orthodontic treatment for better occlusion, improved oral function and harmonized facial appearance. However, two perplexing challenges have not been solved in clinical orthodontics, i.e. long treatment time (on average 2-3 years) and iatrogenic root resorption. Figuring out these challenges will dramatically improve the quality of orthodontic care. The following article deals with the first challenge i.e Long treatment time and the most reliable and effective way to enhance the tooth movement.
今天,许多人接受正畸治疗,以更好地咬合,改善口腔功能和和谐的面部外观。然而,临床正畸治疗时间长(平均2-3年)和医源性牙根吸收是困扰临床正畸治疗的两大难题。解决这些挑战将极大地提高正畸护理的质量。下面的文章讨论了第一个挑战,即治疗时间长和最可靠和有效的方法来增强牙齿的运动。

Deep bite is one of the most common malocclusion which affects children and even adults leading to a number of oral health problems. Patients with deep bite encounter periodontal and temporomandibular problems. Deep overbite refers to the increase of overlap of maxillary incisors over mandibular incisors beyond normal coverage of 30-40%. There are many factors which lead to the development of deep bite like inherent and acquired factors. Inherent factors like tooth morphology, skeletal patterns, rotation of condyle affects the bite. Acquired factors like muscle habits, loss of posterior tooth support or lateral tongue thrust may affect the bite. Deep bite can be corrected by number of different methods which include intrusion of anterior teeth, extrusion of posterior teeth or a combination of both. In non-growing patients surgical treatment is a suitable option to achieve stable results.This article describes various appliances and their biomechanics involved for correcting deepbite malocclusion
深咬是最常见的错牙合之一,影响儿童甚至成人,导致许多口腔健康问题。深咬的患者会遇到牙周和颞下颌的问题。深覆咬是指上颌门牙与下颌门牙的重叠超过正常覆盖的30-40%。导致深咬发育的因素有先天因素和后天因素。固有的因素,如牙齿形态,骨骼模式,髁的旋转影响咬。后天因素,如肌肉习惯、后牙支撑缺失或舌侧推力等,都可能影响咬合力。矫正深咬合的方法有很多,包括前牙侵入、后牙挤压或两者结合。对于未生长的患者,手术治疗是获得稳定结果的合适选择。本文介绍了矫正深咬错所涉及的各种矫治器及其生物力学

Accurate diagnostic imaging is essential to derive the correct diagnosis and treatment plan in orthodontics. In two-dimensional diagnosis, geometric distortion, superimposition of structures, projective displacements, and rotational errors are common. This case series, affirming that the CBCT is vital key in the diagnosis of some specific orthodontic conditions, and presenting five case reports which was difficult to diagnose it with two-dimensional radiograph. Case 1 includes horizontally impacted 21 with crown located labially, and root palatally with close proximity to nasopalatine canal, which was veiled in 2D orthopantomogram. Case 2 is an infrazygomatic implant case, the placement of which was debatable by seeing through the 2D IOPA radiograph. Here, CBCT removed the black curtain and proved its monarchy. Case 3 is a premolar impaction, which in 2D radiograph appeared like an iceberg, but its true anatomy was revealed by the CBCT. After this, the next case 4 is about the central incisor mimicking a canine in 2D radiograph, which was found to be supernumerary tooth on CBCT. Followed by temporomandibular disorder (5) which severity was brought to light by CBCT. The need for this case series is to wave the flag for CBCT in the orthodontic diagnosis which will help in delivering proper treatment plan and emphasis where it is essential to do CBCT.
准确的诊断影像对正畸的正确诊断和治疗方案至关重要。在二维诊断中,几何畸变、结构叠加、投影位移和旋转误差是常见的。本病例系列,肯定了CBCT在某些特定的正畸疾病的诊断中至关重要的关键,并提出了5例难以用二维x线片诊断的病例报告。病例1包括水平阻生21,牙冠位于唇侧,牙根位于腭侧,靠近鼻腭管,在二维正体层摄影中遮挡。病例2为颧下植入病例,其放置位置通过二维IOPA x线片来看是有争议的。在这里,CBCT揭开了黑幕,证明了它的君主制。病例3为前磨牙嵌塞,在二维x线片上表现为冰山状,但CBCT显示其真实解剖结构。在此之后,下一个病例4是关于中央门牙在二维x线片上模仿犬齿,在CBCT上发现是多余的牙齿。其次是颞下颌紊乱(5),其严重程度由CBCT揭示。这个病例系列的需要是在正畸诊断中为CBCT挥舞旗帜,这将有助于提供适当的治疗计划,并强调在哪里做CBCT是必不可少的。

Anchorage has been defined as a resistance to unwanted tooth movement. It is imperative for the treatment of both dental and skeletal malocclusions. Skeletal anchorage provides better chances to obtain absolute anchorage in orthodontic tooth movement. The topic of skeletal anchorage is vast and compiling it in one single article will be an injustice to the readers. So, we have divided this into two review articles under the headings of introduction, evolution and historical background, the means of skeletal anchorage which will be discussed in this first part followed by the design and function of screw-type orthodontic mini-implants, placement sites, surgical procedures, loading approaches, biocortical and resorbable implants and conclusion in the second part.
锚固被定义为抵抗不必要的牙齿运动。对牙齿和骨骼错牙合的治疗都是必要的。在正畸牙齿移动中,骨支抗提供了更好的获得绝对支抗的机会。骨骼锚固的主题是巨大的,汇编在一个单一的文章将是一个不公平的读者。因此,我们分为两篇综述文章,第一部分分别介绍骨支抗的介绍、发展和历史背景,第一部分将讨论骨支抗的方法,第二部分将讨论螺钉式正畸微型种植体的设计和功能、放置位置、手术方法、加载方式、生物皮质和可吸收种植体以及结论。

Precision medicine (PM) is an emerging approach that advocates tailoring healthcare by personalising medical decisions, treatments, behaviours, or goods to a subset of individuals rather than employing a one-drug-fits-all strategy. Molecular diagnostics, imaging, and analytics are examples of precision medicine tools. Precision medical advances foreshadowed comparable advancements in orthodontics, and they can be used to produce tailored treatment approaches and improve treatment efficiency. This article presents an overview of recent developments in computer technology and biomedicine, as well as their current and expected future uses in precision orthodontics. It is necessary to conduct an evaluation of orthodontically relevant technology and developments in relevant biological research. Within the next few decades, advances in computer software and hardware, as well as 3D imaging technology, will offer for more individualised therapy and biomechanical planning. The prospects for personalised orthodontic bracket’s manufacturing with adequate material qualities and digital technology in the future are both appealing and persuasive.
精准医疗(PM)是一种新兴的方法,倡导通过个性化医疗决策、治疗、行为或商品来定制医疗保健,而不是采用一种药物适合所有人的策略。分子诊断、成像和分析是精准医疗工具的例子。精准医学的进步预示着正畸学的类似进步,它们可以用来产生量身定制的治疗方法,提高治疗效率。本文概述了计算机技术和生物医学的最新发展,以及它们在精确正畸中的当前和预期的未来应用。有必要对正畸相关技术和相关生物学研究进展进行评价。在接下来的几十年里,计算机软件和硬件的进步,以及3D成像技术,将提供更多的个性化治疗和生物力学规划。个性化正畸托架的制造在未来具有足够的材料质量和数字技术的前景既吸引人又有说服力。

The incidence of ectopically erupting canine is quite common, reasons are multifactorial, but usually it's the lack of space which happens due to mesial drift of the posterior teeth or the inherent discrepancy between arch length and tooth size discrepancy. If it's the former, distalization is one of the Go-to treatment modality one can opt for provided the nose and lip relation is optimum and does not warrant for extraction. If it's the latter then extraction remains the only choice. This case report discusses an innovative way of aligning a highly placed canine without taxing the anchorage in all 3 planes with help of Skeletal anchorage and Loop mechanics while also correcting the inclinations and gummy smile without hindering nose-lip relation to a certain extent and also tackling the common problem of anatomically short upper lip.
异位突牙的发病率是相当普遍的,其原因是多方面的,但通常是由于后牙的近中漂移或牙弓长度和牙大小的固有差异而导致的空间不足。如果是前者,如果鼻子和嘴唇的关系是最佳的,并且不需要拔除,那么远端化是一种可以选择的治疗方式。如果是后者,那么提取仍然是唯一的选择。本病例报告讨论了一种创新的方法来对齐高度放置的犬,而无需在所有三个平面上使用骨骼锚定和环力学,同时在一定程度上纠正倾斜和粘粘的微笑,而不会妨碍鼻唇关系,同时也解决了解剖上唇短的常见问题。

An easy way to treat buccal canine malocclusion: A case report 一种治疗犬颊错牙合的简易方法:1例报告
Pub Date : 2023-06-15 DOI: 10.18231/j.ijodr.2023.024
Huma Azad, Nabeela Ibrahim, Arbab Anjum, Farheen Akhtar
An ectopic tooth is one that is erupting in an aberrant route, whereas an impacted tooth is one that has failed to fully erupt into the oral cavity within its expected developmental time period and can no longer be expected to do so. The majority of canine eruption abnormalities occur in one of two directions: palatal or buccal displacement from the usual eruptive location 2. Permanent maxillary canine impaction or ectopic eruption affects about 1-2 percent of the general population. Canines that are palatally displaced are twice as common as those that are buccally placed. Buccally displaced canines, on the other hand, are very prevalent in practice and their etiology is related to a deficient dental arch perimeter 3,4. So, the purpose of this report is to show a case of a 15-year-old male with ectopic maxillary canines who was treated by extracting the four first premolars, using segmental T loops for retraction of ectopic canines. The goals were met at the end of treatment with optimal aesthetic balance and excellent occlusal connections, resulting in great long-term stability.
异位牙是指以异常的方式长出的牙齿,而阻生牙是指在预期的发育时期内未能完全长出口腔并且不能再这样做的牙齿。大多数犬的爆发异常发生在两个方向之一:从通常的爆发位置腭或颊移位2。永久性上颌牙嵌塞或异位爆发影响约1- 2%的一般人群。上颚移位的犬科动物是上颚移位的犬科动物的两倍。另一方面,齿龈移位在实践中非常普遍,其病因与牙弓周长缺陷有关3,4。因此,本报告的目的是展示一个15岁的男性上颌犬齿异位的病例,他通过拔除四颗第一前臼齿,使用节段性T环进行异位犬齿的牵回。在治疗结束时达到了最佳的审美平衡和良好的咬合连接的目标,从而产生了很大的长期稳定性。

Andy’s ‘T-pin’Crown and root aligning auxillary 安迪的t型针冠和根尖矫正辅助器
Pub Date : 2023-06-15 DOI: 10.18231/j.ijodr.2023.014

Orthodontists strive for accurate bracket positioning as it helps in achieving an ideal occlusion more easily. For accurate bracket positioning in direct bonding, various hand-held dental instruments are used. Instruments such as, the Boone and Dougherty gauges, MBT gauges, A-KAM and various other modifications, are used for accurate positioning of brackets. Sometimes the bracket can easily slip when the instrument is removed. So, position adjustments are difficult with such an instrument. Indirect bonding is an easy solution, but it is time-consuming and there is no precise repositioning of brackets that fall off and it does not provide proper root paralleling. This led us to develop an auxiliary which can be used for crown and root paralleling or aligning, horizontal, vertical and axial positioning of bracket (Pre-Treatment assessment) during direct bonding. This will avoid the step of repositioning of the bracket at mid or end of the treatment.
正畸医生努力争取准确的托槽定位,因为它有助于实现理想的咬合更容易。为了在直接粘接中准确定位托槽,使用了各种手持牙科器械。仪器,如布恩和多尔蒂量规,MBT量规,A-KAM和各种其他修改,用于准确定位支架。有时支架在器械取出时很容易打滑。因此,这种仪器的位置调整是困难的。间接粘接是一种简单的解决方案,但耗时长,不能精确地重新定位脱落的托槽,也不能提供适当的根平行。因此,我们开发了一种辅助工具,可用于直接粘接时牙冠和牙根的平行或对准,以及托槽的水平、垂直和轴向定位(预处理评估)。这将避免在治疗中期或结束时重新定位支架的步骤。

For accurate bracket positioning in direct bonding, various hand-held dental instruments are used. Instruments such as, the Boone and Dougherty gauges, MBT gauges, A-KAM and various other modifications, are used for accurate positioning of brackets. Sometimes the bracket can easily slip when the instrument is removed. So, position adjustments are difficult with such an instrument. Indirect bonding is an easy solution, but it is time-consuming and there is no precise repositioning of brackets that fall off and it does not provide proper root paralleling. This led us to develop an auxiliary which can be used for crown and root paralleling or aligning, horizontal, vertical and axial positioning of bracket (Pre-Treatment assessment) during direct bonding. This will avoid the step of repositioning of the bracket at mid or end of the treatment.","PeriodicalId":269485,"journal":{"name":"IP Indian Journal of Orthodontics and Dentofacial Research","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121733722","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}

Dental aesthetics have become highly important nowadays. Treating aesthetic needs with non-invasive and with minimal techniques can preserve tissues. Invisalign aligners are an aesthetic and comfortable option too for orthodontic treatment. The increased demand for orthodontic treatment in adults has increased and widened the upper age limit for orthodontic intervention. The antero-posterior skeletal relationship of the maxilla and mandible is determined by the ANB angle. Veneers can be one of the techniques which show excellent aesthetic results and longevity of the treatment. This report highlights the relevant aspects of Invisalign aligners and veneers in a 54-year-old female with the minimal invasive method where the aesthetics of patient was highly improved.
如今,牙科美学已经变得非常重要。用非侵入性和最小的技术来治疗审美需求可以保护组织。对于正畸治疗来说,隐形矫正器是一种既美观又舒适的选择。成人对正畸治疗需求的增加增加并扩大了正畸干预的年龄上限。上颌和下颌骨的前后骨骼关系由ANB角决定。贴面可以是一种表现出优异的美学效果和治疗寿命的技术。本报告重点介绍了一名54岁女性采用微创方法使用Invisalign矫正器和贴面的相关方面,患者的美观性得到了很大的改善。
