Harpreet Singh, Raj Kumar Maurya, Surbhi Thakkar
Complete transposition of teeth is a rather rare phenomenon. After correction of transposed and malaligned lateral incisor and canine, attainment of appropriate individual antagonistic tooth torque is indispensable, which many orthodontists consider to be a herculean task. Here, a novel method is proposed which demonstrates the use of Spec reverse torquing auxillary as an effective adjunctive aid in conjunction with pre-adjusted edgewise brackets.

OBJECTIVE: To introduce a technique of second order wave-shaped arch wire to orthodontically treat dental occlusal plane canting (DOPC) with left-right interactive anchorage, and to test its clinical efficacy. METHODS: Among the permanent dentition malocclusion patients who showed no obvious facial asymmetry, we screened for patients who showed anterior occlusal plane canting (AOPC) after routine orthodontic examination, treatment planning, MBT fixed appliance installation and serial arch wires alignment...

OBJECTIVE: To test the null hypothesis that there is no effect of esthetic perception of smiling profile in three different facial types by a change in the maxillary incisor inclination and position. MATERIALS AND METHODS: A smiling profile photograph with Class I skeletal and dental pattern, normal profile were taken in each of the three facial types dolichofacial, mesofacial, and brachyfacial. Based on the original digital image, 15 smiling profiles in each of the facial types were created using the FACAD software by altering the labiolingual inclination and anteroposterior position of the maxillary incisors...

INTRODUCTION: Esthetics is one of the major concerns among people seeking orthodontic treatment, and its perception varies from person to person. Our objective was to determine the differences in the perception of smile esthetics among orthodontists, general dentists, and laypersons with respect to alteration in the maxillary canine gingival margin in close-up smile analyses. MATERIALS AND METHODS: Close-up photograph of an ideal Indian female smile was selected...

BACKGROUND: Cephalometric analysis and measurements of skull parameters using X-Ray images plays an important role in predicating and monitoring orthodontic treatment. Manual analysis and measurements of cephalometric is considered tedious, time consuming, and subjected to human errors. Several cephalometric systems have been developed to automate the cephalometric procedure; however, no clear insights have been reported about reliability, performance, and usability of those systems. This study utilizes some techniques to evaluate reliability, performance, and usability metric using SUS methods of the developed cephalometric system which has not been reported in previous studies...

INTRODUCTION: Our aims were to assess the perceptions of orthodontic case complexity among orthodontists, general dentists, orthodontic residents, and dental students and to compare their perceptions with the American Board of Orthodontics Discrepancy Index (DI). METHODS: Orthodontists, general dentists, orthodontic residents, and dental students (n = 343) participated in a Web-based survey. Pretreatment orthodontic records of 29 cases with varying DI scores were obtained...

INTRODUCTION: In this retrospective study, we aimed to evaluate the effects on the facial silhouettes produced by a mandibular protraction appliance associated with corrective treatment in Class II patients. METHODS: The sample consisted of 54 (27 initial and 27 final) lateral radiographs from 27 patients. Of these patients, 14 were girls and 13 were boys, with a mean initial age of 12.27 years and a mean treatment period of 2.9 years. An album containing the silhouettes of the pretreatment and posttreatment profiles based on the lateral cephalograms of the patients was prepared...

BACKGROUND: Titanium-molybdenum alloy (TMA) and stainless steel (SS) wires are commonly used in orthodontics as arch-wires for tooth movement. However, plastic deformation phenomenon in these arch-wires seems to be a major concern among orthodontists. This study aimed to compare the mechanical properties of TMA and SS wires with different dimensions. MATERIAL AND METHODS: Seventy-two wire samples (36 TMA and 36 SS) of three different sizes (19×25, 17×25 and 16×22) were analyzed in vitro, with 12 samples in each group...

For better treatment outcomes, dentists usually use a set of parameters for orthodontic evaluation. In this study, a new method is proposed to assist dentists in obtaining reliable assessment of these parameters. The proposed method is based on dental panoramic radiographs and can be divided into four stages: image preprocessing, model training, tooth segmentation and assessment of orthodontic parameters. The image is first normalized and enhanced. Then, the model training stage consists of shape and image model training, energy function training and weight training...

Introduction: the treatment of Class III malocclusion in early age is one of the greatest challenges for orthodontists, and the establishment of more effective treatment method is a constant concern for these professionals. Thus, the objective of this systematic review is to verify the effectiveness of the therapy protocol for alternate rapid maxillary expansion and constriction (Alt-RAMEC) in the early treatment of Class III malocclusion. Methods: searches were performed in the following electronic databases: Cochrane Library, Medline (EBSCO and PubMed), SciELO, LILACS and Scopus...

Lucy Rhodes
Provision of orthodontic care is increasingly the remit of a highly skilled and qualified team, led by a specialist orthodontist. Often separate patient clinics are held in specialist practice for oral hygiene instruction and for impression taking. These tasks are increasingly delivered, under prescription from the specialist orthodontist, by orthodontic nurses (ON) with appropriate post-registration training and/or orthodontic therapists (OT). Nurse or therapist-led clinics can be beneficial in stimulating patient co-operation, enhance both practice efficiency and staff involvement and maximise the patient experience...

AIM: The aim of this in vitro study was to evaluate the influence of the Dental chair light on the bond strength of light cured composite resin. MATERIALS AND METHODS: Sixty therapeutically extracted human premolar teeth were randomly allocated to two groups of 30 specimens each. In both groups light cured composite resin (Transbond XT) and MBT premolar metal brackets (3M Unitek) was used to bond brackets. In group I and II light curing was done using Light-emitting diode light curing units without and with the dental chair light respectively...

Alloplastic chin implants have been a valuable treatment modality for the correction of microgenia. Their use has provided satisfactory esthetic results by improving facial balance. However, bone resorption under these implants can occur. Case reports of 4 patients with the incidental radiographic finding of the presence of chin implants are presented. All 4 subjects had lateral cephalograms and panoramic x-rays taken as part of their orthodontic evaluation. One had a normal mandibular symphyseal contour, and 3 had bone resorption under the implants...

INTRODUCTION: The objective of this study was to evaluate the effect of the orientation of cone-beam computed tomography (CBCT) images on the precision and reliability of 3-dimensional cephalometric landmark identification. METHODS: Ten CBCT scans were used for manual landmark identification. Volume-rendered images were oriented by aligning the Frankfort horizontal and transorbital planes horizontally, and the midsagittal plane vertically. A total of 20 CBCT images (10 as-received and 10 oriented) were anonymized, and 3 random sets were generated for manual landmark plotting by 3 expert orthodontists...

Surgically assisted rapid palatal expansion (SARPE) has been considered a safe procedure with minimal patient morbidity. The aim of this study was to identify short-term complications encountered after tooth-borne expansion with a standardized approach to inform surgeons and orthodontists of the patient risk. In this retrospective cohort study, 55 patients (35 female, 20 male) undergoing SARPE between January 2013 and December 2014 were evaluated. Twenty-eight patients developed one or more complications. Postoperative haemorrhage was seen in six patients...
