All of us, orthodontists, know a little about thehistory of one of the greatest names in modernOrthodontics, Edward Hartley Angle, as we eitherlearned about him during our undergraduateyears, when learning the famous 1889 classificationof malocclusions,1 or in our graduatecourses, when studying the development of theEdgewise appliance (1928).2 However, what fewknow is that, with the purpose of perpetuatingAngle’s idealism, teachings and legacy, a Societywas created 90 years ago, the Edward...

To enhance this issue, this is the first time Clin Orthod interviews aprofessional not directly related to Orthodontics, and I will have theprivilege of presenting him to our readers. Carlos Eduardo de AlmeidaFerreira is a gold standard periodontist and implantodontist whois one of the few that work in synergy with orthodontists. This hasmade him a reference for those who believe in multidisciplinarityas an essential factor for success. He is the son of Dona Joana andCarlos Urbano Gonçalves...

INTRODUCTION: The correction of Class II division 1malocclusion in growing hyperdivergent patients withmandibular retrognathism requires a different approachfrom the traditional treatment, which usually does notprovide good results. OBJECTIVE: This article presentsa case report to illustrate an alternative protocol tocorrect this type of dentofacial deformity, associatingminiscrews to restrain the maxillary vertical growthand a mandibular advancement appliance, to stimulatemandibular growth....

One way to treat dental posterior crossbite isthe progressive posterior torque of the crowns:upper to buccal and lower to lingual. To facilitatethe understanding of the movements, we canplace a typodont tooth with wax perpendicularto the plier (Figs 1 and 2). Another way to helpthinking is to draw a tooth or to engrave witha high speed handpiece and a spherical drill inthe plier’s body (Fig 3). To make the progressivetorque, we mark the distal of the canine on a0.017 x 0.025-in stainless...

INTRODUCTION: Contemporary orthodontics has hadimpressive advances in several fields, notably the emergenceof temporary anchorage devices (TADs), such as mini-implants,and orthodontic aligners. TADs were instrumentalin controlling anchorage and replacing patient collaborationby devices that do not depend on this cooperation.The association between TADs and fixed appliances is wellknown. However, its association with aligners is still littleused by orthodontists. OBJECTIVE: The present study...

INTRODUCTION: Incisors retraction demands control ofthe torque of these teeth. The mechanics used needs to bedifferent depending on how the orthodontist wants theseteeth to be positioned at the end of treatment. OBJECTIVE:This article aims to explain, in a simplified manner, whatis necessary for the orthodontist to control the torque ofmaxillary incisors during retraction. The relationshipbetween the applied retraction force and the binariesto control the lingualization effect will be...

Treatment with intraoral appliances(IOAs) is not restricted tothe delivery of the device. Adequatetreatment involves anactive phase during which anincreasingly anterior positionof the mandible is established.This process is called titrationand can range from weeks tomonths, depending on the severityof the case, possible pain as a side effectof the treatment, and patient compliance.Two points must be considered during the initial titrationphase of the device: One is how the patient willstart...

INTRODUCTION: Slow orthodontic eruption for bonedevelopment in areas of vertical bone defects is a widespreadtechnique in orthodontic literature and has sound scientificevidence. Forces applied to tooth in the occlusal directionlengthen the bundles of gingival and periodontal fibers,generating an osteogenic tension. In consequence of thisprocess, the extrusive movement results in reduction of thepocket depth, increased bone support and change in soft andhard tissue architecture. OBJECTIVES:...

INTRODUCTION: The aesthetic demand has led to theincreasing search for “invisible” aligners in orthodonticclinical practice, among which stands out the Invisalign®system, developed by the Align Technology® company,which has aesthetics and greater chewing comfort as itsmain advantages. With the advent of SmartTrack®, AlignTechnology® started recommending to change alignersafter seven days, allowing a maximum movementof 0.25mm per aligner; however, aligners changes areperformed every ten...

INTRODUCTION: Dental and skeletal Class III malocclusioncan be orthodontically treated in the mixed dentition phase.However, the association of other malocclusion types, suchas deep overbite, implies a higher severity of the case. Consideringthat, it is necessary to use other resources such asa facial mask, which may have its results compromised byinsufficient vertical dimension in deep overbite malocclusion.Therefore, anterior tooth displacement and maxillaryprotraction eventually may be...

OBJECTIVE: To demonstrate that the intraoral appliancedesign can influence the snoring and obstructive sleepapnea (OSA) treatment efficacy. METHOD: Case report ofOSA patient, also presenting snoring and daytime sleepiness.Initial polysomnography (PSG) with an apnea and hypopneaindex (AHI) of 29.8 and oxygen nadir (SpO2) <90% = 5.9%of total sleep time. Non-adherent to CPAP, the patient wasreferred to an intraoral device with mandibular advancement(MAD), fully confectioned with acrylic...

INTRODUCTION: The main causes of dental resorptionsare related to dentoalveolar trauma and tothe orthodontic treatment. OBJECTIVE: To evaluateeducation-related aspects, knowledge and behaviorof dentists registered with the Regional Council ofDentistry of Maranhão state (CRO-MA, Brazil) ondentoalveolar trauma and orthodontic movement ontraumatized teeth. METHODS: Observational studywith application of a questionnaire, submitted througha form on Google Forms and sent to the 173...

OBJECTIVE: This paper aimed to report the clinical caseof a patient presenting Class I malocclusion, bimaxillarydental protrusion, and agenesis of the lateral incisortreated by means of asymmetric and atypical extractionand mini-implants use. CASE DESCRIPTION: As the patientlost some teeth and underwent endodontic treatment inothers, treatment comprised the atypical extraction ofteeth #26, and extraction of teeth #34 and #44. Also due tothe loss of tooth #37, tooth #27 was extruded,...

The Yin-Yang archwire is a non-invasive option for treatingpatients with occlusal cants. Developed in 2019, it isa continuous archwire that is conventionally ligated toeach bracket. It essentially consists of a curve of Spee onone side of the archwire and reverse curve of Spee on theother. The Yin-Yang archwire uses reciprocal anchoragefor cant correction, extruding one side while intruding theother. The following case illustrates the use of the Yin-Yangarchwire in the improvement of a...

INTRODUCTION: When the third molars are not inocclusion, they are a source of problems such asresorption in the second molars and/or in their ownstructure, pericoronitis, paradental cyst, other cystsand odontogenic tumors. When partially erupted,they are entry points for microorganisms and thiscan compromise the general health of the patient,especially those with a systemic disease, regardlessof age. CONCLUSION: Extraction before orthodontictreatment is a way to prevent the clinical...

OBJECTIVE: The objective of this article was to reporta clinical case in which the knowledge on facial growthand development of dentition allowed favorable growthredirection in a girl with concave profile, early at theage of 6 years and 2 months. RESULTS: By means ofmaxillary expansion, adequate management of theLeeway space during the mixed dentition and utilizationof headgear, it was possible to solve the tooth-sizediscrepancy, eliminating the crowding without theneed for extractions....
