In this editorial, I decided to make an overviewof the articles that will compose this edition,since our journal has recently undergone areformulation of sections and columns. As thereader may have seen, we have adopted two newclinical sections over time: “Clinician’s Corner”and “Aligner’s Corner”. These current sections willcompose all editions, and are aimed at providinginformation to the clinician, demonstrating, forexample, an innovative technique or a clinical tip,of interest...

My admiration for Maz has grown with each day I enjoyhis friendship and knowledge. Actually, I need to say thatin the past I was skeptical about aligners and today I cansay that this area in Orthodontics, in my special case, hasto be classified into “before Maz and after Maz”. That’s howmuch I admire his work, professionalism and efficiency.

O rthodontics has been changing: alongeach decade, we find new ways fororthopedic and orthodontic treatment.Aligners, digital planning,intraoral scanning, 3D-printing appliances,mini-implant anchored expanders are someof the examples of the “New Orthodontics”.However, among so many new features, somepractices are timeless. We know that some ofthe treatments are widely used by orthodontists,even though they are out of the limelight. Our oldgood Rapid Maxillary Expansion (RME) is anexample...

Cases of early loss of mandibular firstmolars are common, resulting in mesialinclination of the mandibular secondmolars and extrusion of the maxillaryfirst molars into the extraction space. There areseveral ways to intrude the first maxillary molars,such as, for example, the use of two mini-implants,one in the buccal and the other in the palatal,with the use of elastomeric chains, creating a safeand efficient system, with well controlled forcesand predictable movement. When...

INTRODUCTION: The Intrusion Line appliance aims atcorrecting the open bite. Its biggest advantage is the factthat there is no need for space between the roots, since themini-implants are inserted in the palate. DESCRIPTION:This device consists of a set of hooks supported on mini-implantsassociated with a transpalatal arch. RESULTS: it isan effective tool for orthodontists. CONCLUSION: In orderto achieve success using the Intrusion Line appliance, caremust be taken when installing the...

INTRODUCTION: Maxillary transverse deficiency andposterior crossbite are highly prevalent malocclusions indeciduous and mixed dentitions. Moreover, if not treated atan early age, these can cause damage to the craniofacialgrowth and development of the child. METHODS: Thereis a wide range of etiological factors within these malocclusions,with non-nutritive sucking habits being themost frequently reported. It is common for patients withthese habits to develop maxillary atresia in the shape of...

INTRODUCTION: Patients with cleft lip and palaterequire primary surgeries in the early years of life as thefirst part of treatment. In addition to these surgeries, insome cases orthognathic surgery is also necessary afterorthodontic preparation in the permanent dentition,as a form of correction of sagittal discrepancy, due todeficiency of maxillary development in the sagittal direction.CASE REPORT: In this context, this article reportsthe case of a 9-year-old female patient with...

OBJECTIVE: To evaluate the friction force and surfaceroughness of three different nickel-titanium wires.MATERIAL AND METHODS: Three different wires ofthe same thickness (0.016 x 0.022-in) were evaluated:Flexy Blue-Ti Superelastic NiTi (Orthometric, Marília/SP,Brazil); NiTi Superelastic Black (Ortho-Organizers,Carlsbad, CA, USA) and NiTi Thermal Smart (Orthometric,Marília/SP, Brazil). For each type, 10 samplesof 30mm each were tested. The wires were adaptedin a self-ligating lower incisor...

INTRODUCTION: Orthodontic fixed retainers areeffective in maintaining the treatment results, asthey do not require patient cooperation for theiruse. However, these retainers tend to predispose toplaque and calculus accumulation, and sometimesare related to unexpected post-treatment changes inthe labiolingual inclination or position of mandibularanterior teeth. Based on this, the hygienic orthodonticretainers are designed for interproximal plaquecontrol. However, inadvertent tooth movement...

OBJECTIVE: To present the diagnosis, planning andtreatment of a Class III skeletal and dental malocclusionin a 14-year-old patient. CASE REPORT:A complete Class III molar relationship on the leftside, a deviation of the lower midline to the rightside, and an anterior and posterior crossbite at thesame side, were characteristics of this malocclusion.The lack of initial collaboration of the patient (whowas in the pubertal growth spurt phase) and thegeneralized presence of diastemas in both...

Twenty years after a publication that changed the knowledgeabout the cementoenamel junction and became oneof the most often cited studies about tooth bleaching andexternal cervical resorption in the world, will be reportedhere the contributions of that study to the understandingof clinical events that affect the cervical area of teeth,such as: external cervical resorptions, post-bleachingdentin hypersensitivity and abfraction, particularlythose conditions associated with clinical...
