Introduction: Management of Class II Subdivision cases pose a clinical dilemma and require a careful diagnosis to ascertain the source of asymmetry. Various treatment modalities involving: different protocols of tooth extractions; molar distalization; fixed functional appliances or orthognathic surgery have been proposed for the same. Objective: This article reports a unique approach for management of a severe skeletal Class II with Angle’s Class II Division 1 subdivision malocclusion using unilateral bicuspid extractions in mandibular and maxillary arches and a fixed functional appliance. Results: A 13 year 1 month old male in CVMI transition stage was successfully treated. Extraction of #44 was done to alleviate crowding in the mandibular anterior region and #15 was extracted to protract #16 to achieve a Class II molar relationship. A pre-functional Class II molar and canine relationship with co-incident midlines was achieved. The functional phase consisted of a fixed functional appliance (Forsus FRD) for mandibular advancement to correct the severe skeletal Class II. Class I molar and canine relationships were achieved with reduction of facial convexity and overjet. Result remained stable 24 months after treatment. The improvement can be quantified by the reduction in scores of orthodontic indices measured pre and post treatment. Conclusions: Management of Class II subdivision malocclusion requires careful planning. This paper presents a unique approach utilizing unilateral extractions and fixed functional appliance to address severe skeletal Class II discrepancy and the subdivision dilemma.

Introduction -Transverse discrepancies of the maxilla are one of the most prevalent skeletal problems. Due to drawbacks of conventional RPE and invasive surgical expansion methods alternative methods were developed such as Mini Implant-supported rapid maxillary expansion (MARPE).Haas17 , Davis and Kronman18, Akkaya et al19 and many other studies have reported the maxillary response after MARPE on the sagittal dimensions, but their results were inconclusive. Aim - This study analyzed the effects on the maxilla in the sagittal dimension after Mini Implant assisted rapid palatal expansion (MARPE) in adolescents using CBCT. Material and method -A pretreatment CBCT image (T1) was taken as a standard initial record for all patients and post treatment CBCT (T2) was taken after three months in retention. The parameters SNA angle, Frankfort horizontal plane to NA angle, A-N perpendicular, ANS –PNS were measured and calculated for evaluation of the sagittal maxillary changes. Comparisons were then made between the two treatment groups (T1, T2). Result -There was a positive increase in both angular and linear measurements from pretreatment to post treatment measurements showing significant skeletal changes in sagittal dimension. Conclusion -The study concludes that there was statistically significant forward displacement of maxilla after transverse skeletal expansion in patients with transverse problems achieved through MARPE in adolescent patients.
上颌骨的横向差异是最普遍的骨骼问题之一。由于传统的RPE和有创手术扩张方法的缺点，人们开发了诸如Mini种植体支持的上颌快速扩张(MARPE)等替代方法。Haas17, Davis and Kronman18, Akkaya等许多研究报道了MARPE后上颌矢状面的反应，但其结果尚无定论。目的:利用CBCT分析微型种植体辅助腭快速扩张(MARPE)对青少年上颌矢状面尺寸的影响。材料与方法-预处理CBCT图像(T1)作为所有患者的标准初始记录，留置3个月后取治疗后CBCT (T2)。测量并计算SNA角、法兰克福水平面到NA角、A-N垂线、ANS -PNS等参数，评价上颌矢状面变化。然后对两个治疗组(T1, T2)进行比较。结果-从治疗前到治疗后的角度和线性测量都有积极的增加，显示出骨骼矢状面尺寸的显著变化。结论-研究结论:青少年患者通过MARPE实现横向问题的患者，其横向骨骼扩张后的上颌骨前移位具有统计学意义。

Adolescents with bad malocclusion can more often be victims of bullying and the improvement of their facial appearance through oral rehabilitation is nowadays an important issue. The aim of this case report was to describe the orthodontic treatment in a teenager with a dentoskeletal malocclusion exposed to bullying to correct his occlusal problems and improve facial esthetics and quality of life. The patient, a boy aged 13.5 years, had a class II, division 1, malocclusion with hyperdivergent pattern, mandibular asymmetry, constricted maxillary arch and molar crossbite, increased overjet, lower mild crowding and lip sucking. A two-phase approach was necessary to achieve proper occlusion, better esthetics and promote the patient's self-esteem with consequent greater serenity of his family.

In this case report, Authors describe the correction of a class II malocclusion using only an Herbst appliance palatally anchored with miniscrews. Before sagittal correction in the same appliance we applied a palatal screw to obtain maxillary expansion. The device were removed after 12 months of treatment. The final result included the correction of Class II malocclusion by lower dentoalveolar compensation mainly. The lip function favorite the spontaneous correction of upper frontal torque with consequent improvement of facial esthetics. After a follow up of 12 months the clinical result is satisfactory in terms of occlusion and esthetics. This clinical case showed a simple orthopedic and dentoalveolar approach to correct transversal discrepancy, dental class II malocclusion and also frontal proclination only with one appliance in a very short treatment time.

Background Anthropometrical points or landmarks are key for facial shape analysis using geometric morphometrics. In the early 1990s Fred Bookstein created a classification system with landmarks type 1., type 2., type 3. based on anatomical landmark homology. However, thirty years later, a uniform referece index of landmarks that can be used for assessing facial asymmetry still does not exist. The criteria for selecting landmark points are not fully defined, which makes classification of homology and and landmarks prone to arbitrary interpretations. A systematic review of literature indicates that authors of studies do not provide explanation for choosing exact points. Most of them also do not provide a clear definition of landmarks and landmarks classification according to homology. Objective The objective of this systematic review was to assess, in an evidence based manner, which landmarks inside the Bookstein groups of on facial hard tissues can be reccomended for facial asymmetry assessment using geometric mophometrics. Search methods An electronic search of 9 databases up to March 2020 by two reviewers was conducted to identify relevant articles. Selection criteria Prospective randomized, non-randomized controlled trials and cross sectional studies reporting on facial asymmetry using three-dimensional images and geometric morphometric methods. The reasons for assessing facial asymmetry were not considered. Data collection and analysis The 23 selected studies were categorized according to the number and specification of the research subjects, types of three-dimensional images, number of landmarks, and the craniofacial region of interest. All landmarks were extracted with the following data: name, abbreviation, and the author’s definition of the location. Results The craniofacial region is divided into neurobasic cranial part, ethmomaxillar part and the mandible. Assessment of neurobasic cranial asymmetry was conducted in 6 studies and 45 different landmarks were recorded, of which 11 were medial and 34 bilateral. Bregma and Lambda occur most frequently and according to homology both belong to type 1 landmarks. Assessment of ethmomaxillary asymmetry was conducted in 21 studies and 68 different landmarks were recorded, of which 16 were medial and 52 bilateral. Nasion and Jugale occur most frequently and according to homology Nasion belongs to type 1 landmarks and Jugale to type 2 landmarks. Conclusion The selection and definition of craniofacial hard tissue landmarks is one of the most important tasks in the design of morphometric studies, and thus for the purpose of assessing facial asymmetry. The review provides an extensive cross-section of possible landmarks with the definition of the location as well as the possible location variation. The list of these landmarks should be observed through the classification of landmarks according to their homology, as well as possible variations of the classification.

Introduction: Debonding pain is an unpleasant sensation that is frequently encountered during debonding procedure. Aim of the study: To investigate the effectiveness of cotton roll-biting on pain caused by the debonding procedure. Materials and methods: 102 patients (61 females, 41 males) who were at the debonding stage in orthodontic treatment were included in the research. The study was planned using a split-mouth design: one side of the jaw was the study, and the other side was the control. The anxiety level of participants was measured before debonding. On the study side, debonding was performed while patients were biting a cotton roll. On the control side, debonding was implemented as a routine debonding procedure. Study and control sides were assigned differently in each successive patient. The debonding pain of each tooth was recorded using the Visual Analog Scale prepared separately for each tooth. Shapiro–Wilk and Mann–Whitney U tests were used for statistical analysis. For both gender groups, patients were sequenced according to the average amount of pain per tooth. Subsequently, statistical analysis was repeated by using 50% of patients suffering more pain. Results: In the lower second premolar tooth, a statistically significant difference was detected. Pain scores were statistically higher in the study side for this tooth. No statistically significant differences were found for all other teeth. Conclusions: Cotton roll-biting has no alleviating effect on debonding pain. When debonding is performed gently using a squeezing action without applying torsional forces, additional pain relief methods are not required.

Retention is one of the most critical phase of Orthodontic treatment . Angle stated that "the problem involved in retention are greater than the difficulties being encountered in the treatment, and tests the utmost skill of the operator. The various retention appliances available include Removable retainers and bonded retainers. Removable retainers have their own advantages and disadvantages, but they need patient’s compliance to wear them.Fixed retainers consist of a length of orthodontic wire that is bonded on the lingual aspect of tooth .The major advantages of bonded retainers includes invisibility, no patient compliance required and long term retention. Bonding of a lingual retainer is a challenging and technique sensitive procedure because it requires long working time and has a risk of contamination from saliva and moisture, leading to bond failure as it is difficult to adaptation of the retainer wire and further stabilization of contoured retainer wire in the oral cavity during bonding. If retainer wire can be effectively stabilized over the lingual surface of tooth prior to bonding, bonding becomes a simple process. Various methods used to stabilize lingual retainer before bonding involves use of separators (Kesling and elastomeric separators), materials like resin, memosil, glue etc or use of metal Stablizers in form of W,V or use of wires . The objectives of this article is to compile the different retention techniques used to stabilize the lingual retainer wire for bonding altogether at one place.

Introduction: The eventual esthetic solution for patients who do not want visible orthodontic appliance is the lingual orthodontic appliance. The result produced by the lingual orthodontic appliance is parallel to those produced by the labial orthodontic appliance. However, there is an articulation problem due to the position of the lingual brackets as there is a modification of the lingual surface of the teeth. Speech problems with each appliance are studied individually and extensively, but the comparison of both appliances regarding speech is very scanty. Aim: The aim of this study is to evaluate the effect of fixed labial and lingual orthodontic appliance on speech sound production at a different time interval. Materials and methods: A total number of 30 patients were included in this study, 15 patients were bonded with the fixed labial appliance (Group 1) and 15 patients were bonded with the fixed self-ligating lingual appliance (Group 2). Based on four types of errors (E1, E2, E3, E4), a total of nine groups of sounds (S1, S2, S3, S4, S5, S6, S7, S8, S9) were evaluated for each audiovisual sample at four different time intervals (T1, T2, T3, T4) by two different speech therapist individually in each group. Results: A high degree of agreement was found between the two observers in both groups regarding the type of sound effected and the type of error during sound production. The total number of patients with effected speech is more in the lingual group compared to the labial group on the same day of bonding until six months in treatment. Conclusion: The results of the present study demonstrated the following, the total number of patients with lingual appliance had more errors in speech compared to the labial appliance at the beginning of the treatment. Patients with lingual appliance required more time for adaptation concerning speech. A similar group of sounds was effected in both types of an appliance with a similar type of error. Patients with labial appliance showed more comfort and easier adaptation with the appliance. The anatomical location of the appliance plays an important role in speech alteration and adaptation. These findings should be considered before selecting an appliance for a particular patient.

简介:最终的美学解决方案的患者谁不想要可见的正畸矫治器是舌正畸矫治器。舌正畸矫治器产生的结果与唇正畸矫治器产生的结果平行。然而，由于舌托槽的位置，由于牙齿舌面有修饰，因此存在发音问题。每个器具的语音问题都被单独和广泛地研究过，但两种器具在语音方面的比较却很少。目的:本研究的目的是评估固定唇舌矫正器在不同时间间隔对语音产生的影响。材料和方法:总数的30个病人都包括在这项研究中,15例与固定唇保税设备(组1)和15例保税固定self-ligating舌设备(组2)。基于四种类型的错误(E1, E2, E3, E4),共9组的声音(S1, S2、S3、S4 S5, S6, S7、S8, S9)进行评估每个视听样本在四个不同的时间间隔(T1、T2、T3、T4)在每组分别由两个不同的语言治疗师。结果:在两组的两个观察者之间发现了高度的一致，关于声音产生过程中产生的声音类型和错误类型。在治疗6个月前，舌组在粘接当天出现的言语影响患者总数多于唇组。结论:本研究结果表明:使用舌形矫治器的患者在治疗初期比使用唇形矫治器的患者有更多的言语错误。使用舌器的患者需要更多的时间来适应语言。类似的一组声音在两种类型的器具中都有类似的错误。使用唇部矫治器的患者更舒适，更容易适应。矫治器的解剖位置在言语改变和适应中起着重要的作用。在为特定患者选择矫治器之前，应考虑这些结果。通讯作者:Dansih Intesaab Ahmed口腔正畸和牙面矫形科，M.A.Rangoonwala牙科科学与研究中心，浦那1，印度e-mail:intesaab_001@yahoo.com固定唇部和舌部正畸矫形器对语音产生的影响:一项比较体内研究介绍将思想转化为语言并将这些语言组织成具有语法背景的序列的复杂心理生理过程称为语音。语言的生理媒介有呼吸、发音和发音。牙齿与嘴唇和舌头一起，在气流阻塞和修饰辅音的发音中起着重要作用。因此，牙齿位置可能在发音障碍中起作用在这个时代，越来越多的专业成年人寻求正畸治疗;正畸医师需要认识并确定可能影响沟通完整性的危险因素。值得注意的是，成年人对传统固定唇部正畸矫治器的美观性反应冷淡。修订日期:2019年10月7日;发布日期:2019年10月24日李建军，李建军，李建军，等。固定唇部矫治器和舌部矫治器对语音产生的影响。中华口腔医学杂志，2019;6(2):27-34。South Eur J Orthod dentoface Res Ahmed DI等。正畸矫治器对语音产生的影响28并想要隐藏它们。最近的进步，如塑料和陶瓷支架和美学弓线在市场上是可用的，但对上述问题的最终解决方案是将支架放置在牙齿的舌面解决唇部矫治器造成的美观问题的方法是发展舌部矫治器。舌矫治器的最终效果与唇矫治器一样好。3-6由于放置舌托而改变了牙齿的舌面，这可能经常引起发音问题。7-11其他报告给舌矫治器的问题是口腔不适、咀嚼困难和舌头刺激。以上提到的问题可能会导致比可见唇托更大的社交尴尬关于两种器具在治疗过程中不适的个体比较的研究很多，但两者之间的比较很少。11-15然而，与唇部矫治器相比，舌部矫治器引起的口腔不适的强度和程度尚不清楚。

Girija","doi":"10.5937/sejodr6-23904","DOIUrl":"https://doi.org/10.5937/sejodr6-23904","url":null,"abstract":"Introduction: The eventual esthetic solution for patients who do not want visible orthodontic appliance is the lingual orthodontic appliance. The result produced by the lingual orthodontic appliance is parallel to those produced by the labial orthodontic appliance. However, there is an articulation problem due to the position of the lingual brackets as there is a modification of the lingual surface of the teeth. Speech problems with each appliance are studied individually and extensively, but the comparison of both appliances regarding speech is very scanty. Aim: The aim of this study is to evaluate the effect of fixed labial and lingual orthodontic appliance on speech sound production at a different time interval. Materials and methods: A total number of 30 patients were included in this study, 15 patients were bonded with the fixed labial appliance (Group 1) and 15 patients were bonded with the fixed self-ligating lingual appliance (Group 2). Based on four types of errors (E1, E2, E3, E4), a total of nine groups of sounds (S1, S2, S3, S4, S5, S6, S7, S8, S9) were evaluated for each audiovisual sample at four different time intervals (T1, T2, T3, T4) by two different speech therapist individually in each group. Results: A high degree of agreement was found between the two observers in both groups regarding the type of sound effected and the type of error during sound production. The total number of patients with effected speech is more in the lingual group compared to the labial group on the same day of bonding until six months in treatment. Conclusion: The results of the present study demonstrated the following, the total number of patients with lingual appliance had more errors in speech compared to the labial appliance at the beginning of the treatment. Patients with lingual appliance required more time for adaptation concerning speech. A similar group of sounds was effected in both types of an appliance with a similar type of error. Patients with labial appliance showed more comfort and easier adaptation with the appliance. The anatomical location of the appliance plays an important role in speech alteration and adaptation. These findings should be considered before selecting an appliance for a particular patient.

Introduction: This case report describes the treatment of a crowded dental Class II malocclusion in 13 years, 2 months female patient. Maxillary distalization was achieved by a novel compliance-free appliance referred to as MaXimo, which was built by a rearrangement of the Leaf Expander® screw having palatal miniscrews as the anchorage core. Case Presentation: Pre-treatment, post-treatment and 1-year follow-up records are shown. No side effects, breakage of the appliance or loss of miniscrews was encountered. The active distalization phase lasted 14 months, while the whole treatment, including the use of multibrackets appliance, lasted 25 months. A significant spontaneous distal drifting of the premolars and canines was seen. The treatment outcomes proved to be stable at the follow-up with acceptable aesthetic and functional results. Conclusion: The MaXimo appliance proved to be efficient and of easy management, and its use may be recommended when distalization of the maxillary dentition is required. Being mostly assembled by the manufactured, the MaXimo appliance is also cheap and of easy construction.
