cation movements, and in orthodontic terms, these are the uncontrolled tipping. True, pure rotations, intrusion, and extrusions can be detected only when the parallelogram or the net force happens to act exactly along the vertical axis of the tooth (for extrusion or intrusion) or around it (for rotation). Those movements if occur, may last for very short time only, and therefore are very limited.1 Torque and torque derivative movements (bodily, root movements or controlled tipping for example) are the outcome of a couple (a pair of opposite forces in different parallel lines of action, whose vectors are equal in magnitude), or a couple in conjunction with force, respectively, and are considered to be more complicated orthodontic movements that enroll at least two points force application, where there is a firm and long lasting ’fusion’ between the moving and the driving parts. The couple, placed in the bracket, is the only system that can rotate the affected teeth, around an axis developed in the mid-bracket itself, and not at the center of resistance of the tooth, as other movements do. This movement is unique to fixed appliances and not to removable appliances including the aligners. Therefore, those movement cannot be accomplished by removable aligners, where the teeth are free to move in space, since the appliance is removable. Let us assume that we can develop a couple on a tooth crown surface by using aligners (with for example attachments and/or power ridges). This couple, if exists, may be present only momentarily, immediately following the wear of the aligner. Its immediate effect on the crown changes the spatial position of the tooth relative to the couple’s two points of application, and the pre-engineered program embedded in the aligner loses its “couple” qualities into a single point force application (tipping force). The removable plastic aligner cannot “trace” or follow the moving tooth, and therefore no persistent couple continuation can be delivered on the teeth.

Aim To analyze the pulpal stress in varied orthodontic tooth movements at ideal force levels and different bone levels, and compare any differences in pulpal stress values between anterior and posterior teeth. Materials and Methods Four Finite Element Method models of incisor and molar teeth were simulated with normal bone height and 50% bone height. Each of these models was loaded with five different types of orthodontic tooth movements—Tipping, Translation, Intrusion, Extrusion, and Rotation. The ideal force levels simulated for each type of tooth movement were: Intrusion-20 g, Extrusion-60 g, Tipping-60 g, Translation-120 g, Rotation-60 g. The pulpal stress was evaluated at three levels—pulp chamber, pulp canal, and below root apex, so that we get three values of pulpal stress for anterior and posterior teeth, for each type of tooth movement and its corresponding force level. Results The results showed that in both incisor and molar models with normal bone height as well as 50% bone height, rotation gave the highest pulpal stress while translation gave the least. In both incisor and molar models with normal bone height as well as 50% bone height, pulpal stress was found out to be highest in the root apex region of the tooth. The stress values for incisor and molar models with 50% bone height were found to be almost double that of the models with normal bone height. The pulpal stress for incisor teeth was found to be greater than the molar teeth for all types of tooth movement. Conclusion The present findings indicate that the stress manifested below the root apex is highest. Rotational movements induce the highest stress and translational forces develop the lowest stress related to the physiologic capillary blood pressure. Furthermore, in situations with reduced periodontium, lower forces are needed to reach the maximum tolerable stress compared with teeth with intact periodontium.

Fixed functional appliances are used at either the fag end of the growth spurt or after the completion of the same. We orthodontists are yet to come across an appliance which satisfies all the ideal requirements for a fixed functional appliance. Most disadvantages of the fixed functional appliances such as increase in lower anterior facial height, proclination of lower anteriors, constant breakages, and huge expenses were taken into consideration in the basic designing of this ingenious appliance. In this article, a simple fixed functional appliance was designed to function along with fixed appliance therapy to stimulate mandibular growth. After the initial leveling and aligning, 0.019 × 0.025 stainless steel posted arch wires were placed. The bite jumping blocks were fabricated in the upper and lower arches with light cure blue composite. Using indirect bonding trays they were bonded in position. The case finished in an ideal overjet and overbite with a balanced face. Cephalometric values demonstrate an advancement of the mandible.

Introduction In orthodontic treatment, infra-zygomatic crest screws have been effectively used in the correction of borderline skeletal malocclusion. The success of bone screws depends on factors such as biomechanical factors, placement technique, and microbial factors. Therefore, this study aimed to evaluate the success rate as well as assess the microbiota of silver nanoparticle coated and uncoated infra zygomatic crest (IZC) screws on clinical application. Method A sample of 36 stainless steel IZC screws was divided into 2 groups. Group I- Silver nanoparticle (AgNP) coated (n = 18) and group II uncoated (n = 18). A total of 18 patients (4 male, 14 female; mean age 22.58±3.52) received IZC screws (coated or uncoated) via a double-blind, split-mouth design. The success rate was evaluated based on the stability of IZC screws. And also molecular analysis was carried out using terminal restriction fragment length polymorphism complemented with cloning and identification of species. Results The success rate was higher in group I (77.80%) than in group II (50.00%). The mean rank for terminal restriction fragments in AgNP coated group (14.92%) was significantly lower than the uncoated group (22.08%) (P<0.05). The cloning results revealed a major difference in the predominant species composition between AgNP-coated (Prevotella oris sp.) and uncoated IZC screw (Capnocytophaga leadbetteri). Conclusion The success rate for AgNP-coated IZC screws was higher compared to uncoated screws, while predominant bacteria present in coated and uncoated samples were found to be of different biological significance which needs to be explored subsequently.

Objective/Background Craniofacial growth and development is influenced by growth hormone, which is in turn facilitated by the growth hormone receptor (GHR). GHR gene polymorphisms have been found to be associated with mandibular morphology and skeletal facial profiles in various populations. The aim of this study was to determine the association of single nucleotide polymorphisms (SNP) of GHR gene rs6180, rs6182, and rs6184 with maxillomandibular parameters in the Indian population. Setting and Sample Population A cross sectional study was conducted on 174 male and female Indian subjects in the age range of 20 to 32 years who reported for orthodontic treatment. Material and Methods Venous blood and lateral cephalogram were collected from each participant for genetic and cephalometric analysis. Genotypes of each SNP were identified by polymerase chain reaction—restriction fragment length polymorphism. Independent t test and Analysis of Variance (ANOVA) were done for intra and inter group comparisons with SPSS software. Results SNPs rs6180, and rs6182 were found to be associated with sagittal position and length of maxilla and mandible, anterior facial height, and growth pattern. SNP rs6184 did not have any significant association with the craniofacial parameters. Conclusion The results suggest that the GHR gene might be a candidate gene for maxillomandibular morphology in the Indian population.

Background An analysis of the factors influencing the decision-making process in accepting orthodontic treatment can be of profound importance in establishing trust and ensuring an overall positive outcome. This is all the more significant when dealing with a patient who has not had any prior interaction with an orthodontist. The Simplified Malocclusion Index for Layperson Evaluation (SMILE Index) allows an unbiased cross-evaluation between the perceived need for treatment and the factors of orthodontic awareness and self-perceived esthetics. Objectives Tribal adolescents belonging to 2 regions with no prior access to orthodontic treatment were chosen for the study. Most adolescents of this region were assumed to have orthodontic awareness by way of information from their schools and dental camps. During the orthodontic screening process, a verbally assigned questionnaire base index was used to elicit their willingness to undergo treatment and to understand influencing factors. Methods A total of 2,835 tribal adolescents between the ages of 13 and 19 years belonging to the Revenue divisions of Paderu (Visakhapatnam) and Parvathipuram (Vizianagaram) were screened in this study. Chosen candidates presented with normal growth and development, and had no nutritional deficiencies or metabolic disorders. Consent and permissions were obtained from the regional tribal authorities, institutional ethical clearance committee, the school authorities, and the parents or guardians of the adolescents. The orthodontic screening was performed under natural daylight with strict adherence to infection prevention protocol. Observed occlusions were categorized into either an ideal occlusion or Angle’s Class I, II, and III malocclusions. During the screening, the SMILE index was assigned in the vernacular Telugu. A percentage distribution analysis was made of the responses of those presenting with malocclusion. Results An analysis of the SMILE index results of the adolescents of Paderu Revenue division revealed higher SMILE index scores in categories III and V with a percentage distribution of 24.46% for males and 26.86% for females in SMILE Index Score Category III and 63.40% for the males and 52.13% for the females in Category V. Similarly, the results of Parvathipuram division had a higher score distribution in the categories of III and V with a percentage distribution of 16.07% for males and 15.84% for females in category III and 78.67% for males and 74.25% for females in category V. Conclusion Orthodontic treatment with proper counseling providing clarity of facts facilitates an easier decision-making process and enables both the patient and the orthodontist to understand one another and the treatment process better for a much more predictable overall treatment outcome.
