An 11-year-old female patient presented with a chief complaint of labially blocked out maxillary canines and irregular teeth in the upper arch. Clinical examination and evaluation revealed an Angle's Class II malocclusion on an underlying Class II skeletal base with a crowded maxillary arch, blocked out maxillary canines, mild crowding in the mandibular arch, convex profile, and obtuse nasolabial angle. Her skeletal maturity status was Stage III of the cervical vertebrae maturity index (CVMI). A nonextraction treatment plan was considered for this case, which involves bilateral permanent first molar distalization of the maxillary arch using Jones jig distalizer followed by fixed orthodontic mechanotherapy using 022 MBT prescription. The posttreatment outcome shows an appreciable improvement in facial esthetics and occlusion. Further postorthodontic phase has retained a stable occlusion and pleasing facial profile.

To summarize the details on severe acute respiratory syndrome-coronavirus-2 (SARS-Cov-2) viral infection and the effects of this infection on care of patients with orofacial clefts and provision of guidelines for orofacial cleft surgeries during Corona virus disease 2019 (COVID-19) by using recent available literature. PubMed and Google Scholar and current reports from major health bodies such as the Centers of Disease Control and Prevention, World Health Organization, National Institutes of Health, and major national associations of cleft lip and palate were searched for information which is relevant from orthodontic care for orofacial cleft point of view. Major priority is given to recent articles and peer-reviewed articles. Narration is done due to limitations in the quality of evidence and rapidly evolving information on the nature of COVID-19. Major relevance to the dental field is human-to human transmission of SARS-CoV-2. People who are infected mostly show mild symptoms, but patients with advanced age or any underlying disease or comorbidity may show severe multiorgan complications. During the COVID-19 pandemic, it is important to maintain social distancing and minimize direct contact. Most clinics and hospitals have determined that multidisciplinary visits, feeding, and speech-language evaluations are largely nonessential and can tolerate a delay. A specific plan with good foundation should be followed for emergency orthodontic care with effective communication and triage.

Introduction: As we witness the soft-tissue paradigm, treating the face becomes more important than just treating the hard tissue variables. Therefore, it becomes crucial to quantify the soft-tissue response to changes in the hard tissue following orthodontic treatment. Purpose of the Study: To determine lip morphology changes after first premolar extractions in patients with bimaxillary protrusion as ratios of hard and soft-tissue changes. Materials and Methods: The sample consisted of pretreatment and posttreatment lateral cephalograms of 15 subjects with Class I bimaxillary protrusion who had undergone orthodontic treatment with four first premolars extraction and retraction of upper and lower incisors. Pre- and post-treatment lateral cephalograms were traced and superimposed by using SN-7˚ plane. Sixteen linear measurements were made. Statistical analysis was performed to analyze the co-relation between the hard and soft tissue change by Pearson's correlation. Stepwise multiple regression were made to determine factors that related with lip changes. Results: Significant changes after treatment were found both in dental and lip analysis. The equations of upper and lower lip changes in sagittal and vertical dimensions were derived. Conclusion: Stepwise multiple regression analysis revealed that a 1 mm retraction of the maxillary incisor cervical point would produce a 0.59 mm retraction of upper lip and 1 mm retraction of the mandibular incisor cervical point would produce 0.89 mm retraction of the lower lip. The predictability of this study may be helpful for the clinician in predicting the amount of change in profile of the patient post treatment, thus aiding in planning the treatment.

Background: The aim of the study was to compare and evaluate the frictional resistance of clarity advanced ceramic brackets, metal insert ceramic bracket, and conventional metal brackets with Nickel–titanium wire and stainless-steel archwire of varying dimensions. Materials and Methods: The sample size with 80% power was 45. The samples were divided into three groups each group consisting of 15, Group 1 – Clarity Advanced Ceramic Brackets (3M Unitek). Group 2 – Metal insert Ceramic Brackets (3M Unitek). Group 3 – Conventional Metal Brackets, the control group (3M Unitek). The wires used for testing were 0.016” Niti, 0.017 ×× 0.025” Niti and 0.019 ×× 0.025” SS. Results: In the present study, it was found that wire material (nickel titanium) had an effect on friction. It was found that metal insert ceramic bracket exhibited similar frictional resistance when compared to metal brackets for 0.017 × ×0.025” Niti and 0.019 × 0.025” SS wires. The Clarity Advanced bracket had the highest frictional resistance followed by metal insert ceramic and least with the conventional metal. Conclusion: Clarity advanced can be the bracket of choice for the esthetically discerning patients who do not require extraction for orthodontic reasons, but the high frictional resistance in relation to larger rectangular Niti archwires should be considered. In adult patients who require extraction in the treatment plan, metal insert ceramic brackets are definitely a pleasing alternative when compared to metal brackets.

This review article presents various fixed functional appliances that have been developed all these years with the aim of correcting Class II malocclusion. Class II malocclusion though multifactorial in etiology, but the main cause is mandibular retrognathia. The treatment aims to modify the direction and amount of mandibular growth rather than restricting the development of the maxilla. Hence, the various appliances were developed removable and fixed with the aim to correct Class II malocclusion. Fixed functional appliances were developed with the aim to correct Class II malocclusion without the need of patient compliance, which was a major concern toward removable functional appliances.
