Myofunctional appliances are highly effective in growing patients and are often used to correct jaw discrepancies and promote optimal growth. The twin block appliance is widely considered as the most efficacious myofunctional appliance for treating skeletal class II malocclusion in growing patients. The success of treatment with any myofunctional appliance depends on a variety of factors, including the patient's age, growth status, growth pattern, the specific malocclusion being treated, patient compliance, the type of appliance, and other case selection criteria, such as clinical examination and certain cephalometric parameters that are not typically considered in routine practice. Among cephalometric parameters, the saddle angle is of utmost importance and should always be considered before commencing myofunctional therapy. Patients with a large saddle angle may have a class II skeletal relationship, characterized by a posteriorly positioned mandible. These cases can be more challenging to treat with functional appliances alone and may require additional orthodontic or surgical interventions. This paper presents a detailed description of three cases illustrating the importance of the saddle angle in the success of myofunctional therapy.

: This study evaluated the duration for distalization of canine and the amount of root resorption with and without piezocision. : The study sample consisted of 15 adult patients in a prospective split-mouth study design, requiring therapeutic extraction of bilateral maxillary first premolar and bilateral canine distalization. The subjects were evaluated for the time taken for the maxillary canine to achieve a positive contact with the maxillary second premolars bilaterally. Intervention in form of piezocision was carried out on one side of the maxillary arch using piezotome vis-a viz the control side. The study further uses pre & post CBCT records to evaluate the amount of blunting of the maxillary canine root apexes bilaterally when distalization was completed. : Duration of canine retraction in the piezocision group was 4.66 ± 0.52 months which is comparatively faster than that of the control group which took almost 5.72 ± 0.65 months. : The study concluded that the use of piezocision in cases of individual maxillary canine retraction results in a shorter duration of maxillary canine distalization and overall treatment time, with no significant difference in root resorption with or without piezocision.

To evaluate changes in hypopharyngeal airway space and effective length of mandible in skeletal Class II patients following Twin Block Appliance (TBA) therapy. Further, the study also aims to compare the post functional changes being observed between males and females. This is a prospective study on 15 Pre-adolescents (08 males and 07 females; mean age: 10.75 ± 0.91years) who underwent functional jaw orthopaedics with TBA. Lateral cephalogram at Pre treatment stage (T1) and post functional phase of TBA (T2) were obtained. The cephalometric parameters were measured and paired t test was done for comparison of pre and post functional changes. The mean period of functional phase of TBA therapy was 18 ± 02 months. The cephalometric changes post functional jaw orthopaedics were statistically insignificant when compared males Vs females (P > 0.05). However, mean increase of in the effective length of mandible and hypopharyngeal space (T2-T1) was 4.0± 1.16 mm and 1.47±0.57 mm respectively, which were statistically highly significant (P<0.5). 1. TBA therapy in skeletal Class II patients significantly increases the effective mandibular length and hypo-pharyngeal space post functional phase; 2. No significant differences were observed between males and females with respect to post functional cephalometric changes in mandibular length and hypopharyngeal space.

The objective of study was to evaluate and compare the efficacy of Probiotic toothpaste, fluoridated toothpaste and non-fluoridated toothpaste (control) on the levels in the plaque surrounding orthodontic brackets. The randomly selected patients are divided into 3 groups (20 each) on the basis of type of toothpaste given to them. The patients in groups were asked to brush twice daily with given toothpastes and to discontinue using their normal toothpaste. Plaque specimens were collected from the labial surfaces immediately surrounding the orthodontic brackets of the maxillary lateral incisors by four passes, each along the tooth at the bracket inter-face at the gingival, mesial, distal, and occlusal aspects. The isolated plaque is sent to Microbiology laboratory soon after collecting in a sterile container. The presence of was evaluated in colony forming unit through culture formation and statistical analysis was performed, and comparisons were made. After one month application of a probiotic containing toothpaste (group 3), a fluoridated containing toothpaste (group 2) and a non-fluoridated toothpaste(group 1) the level of significantly reduced in group 2 (non-fluoridated toothpaste) and group3 (Probiotic toothpaste) & minimal reduction is shown in gruop 1. Conclusion: The use of probiotic toothpaste causes a significant decrease in the levels in the plaque around orthodontic brackets in orthodontic patients.

A temporary anchorage device is a device that is temporarily fixed to bone for the purpose of enhancing orthodontic anchorage either by supporting the teeth of the reactive unit or by obviating the need for the reactive unit altogether, and which is subsequently removed after use. Use of mini implants is one of the innovative approach for complex tooth movements such as mesialisation. Space closure from distal to mesial is one of the most difficult orthodontic tasks. Tooth-borne anchorage limits the scale of tooth movement. Extraoral or intraoral appliances are used especially for unilateral space closure. As an alternative to conventional mesialization appliances, osseointegrated implants may be used for maximum anchorage in orthodontic treatment. The use of direct anchorage in the form of installed mini-implant that is connected to the teeth requiring horizontal movement causes low levels of strains on anchor unit comparing to the results that were registered during indirect anchorage with one or two anchor teeth. This report presents the case of removal of mesiodens and blocked out and fractured premolar and the space closure by unilateral mesialisation with the help of mini implants and loops.

This report presents the case of removal of mesiodens and blocked out and fractured premolar and the space closure by unilateral mesialisation with the help of mini implants and loops.","PeriodicalId":376004,"journal":{"name":"Journal of Contemporary Orthodontics","volume":"80 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139774959","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}
The purpose of this study was to estimate and compare the maturation stages of permanent teeth in different facial patterns in Rajasthan population. Pre-treatment lateral cephalograms and orthopantomogram of 90 subjects (30 horizontal, 30 vertical and 30 average growth patterns with subgroup of male and female in horizontal, vertical and average growth pattern), with 8 – 16 years of age, were selected from the patients records who had reported to the Department of Orthodontics & Dentofacial Orthopaedics, Darshan Dental College and Hospital, Udaipur. Lateral Cephalograms were traced manually and orthopantomogram were used to get the overall dental maturity score by adding the value of left eight mandibular teeth. Student’s t test was used to compare the maturation of chronological age and dental age in horizontal, vertical and average growth patterns and Pearson’s correlation test was used to found correlation between the group. The results suggest a difference in dental age and chronological age in subject with vertical growth patterns. Vertical female growers showed early dental age maturation compared to chronological age. There was insignificant difference present in dental age and chronological age in horizontal growth patterns and average growth patterns. Insignificant intergroup difference was found in dental age between horizontal vs vertical, horizontal vs average and vertical vs average growth patterns. Subjects with vertical female growth patterns shows early dental age maturation than chronological age. Sn-Go-Gn, lower anterior facial height and Jara back’s ratio are highly significant in determining growth patterns. There also exists strong correlation between dental age and chronological age in horizontal, vertical and average growth patterns in male and female subgroup.
这项研究的目的是估计和比较拉贾斯坦邦不同面型人群的恒牙成熟阶段。研究人员从向乌代布尔达山牙科学院和医院正畸和牙面矫形科报到的患者记录中选取了 90 名年龄在 8 - 16 岁之间的受试者（30 名水平生长型、30 名垂直生长型和 30 名平均生长型，其中水平生长型、垂直生长型和平均生长型分为男性和女性子组），对他们进行了治疗前的侧向头影和正位像测量。通过手动描记侧头影和正位像图，将下颌左侧八颗牙齿的数值相加，得出牙齿成熟度的总分。采用学生 t 检验比较水平、垂直和平均生长模式下的计时年龄和牙龄成熟度，并采用皮尔逊相关检验发现组间的相关性。结果表明，纵向生长模式的受试者在牙龄和实足年龄方面存在差异。垂直生长女性的牙龄比实际年龄早熟。在横向生长模式和平均生长模式中，牙齿年龄和计时年龄的差异不明显。在横向与纵向、横向与平均、纵向与平均生长模式之间，牙龄的组间差异不明显。纵向女性生长模式的受试者的牙齿年龄比实际年龄成熟得早。Sn-Go-Gn、面部前下方高度和 Jara back's ratio 在决定生长模式方面具有非常重要的意义。在横向、纵向和平均生长模式中，男性和女性亚组的牙齿年龄与计时年龄之间也存在很强的相关性。
