Diretrizes para o tratamento e acompanhamento periodontal durante o tratamento ortodôntico

The aim of this paper was to search though a revision of the literature the cares before, during and after the orthodontic treatment in patients with a periodontal disease. The literature shows that the orthodontical treatment in healthy patients brings no risk to the periodontium, although the presence of an active periodontal disease counter indicates the dental movement. Thus, it is extremely important to execute a correct diagnosis of any periodontal alteration and treat them before the beginning of the orthodontical treatment. Besides, during the whole orthodontical treatment is also important to have a periodontal control with periodic reevaluations and at the end of the orthodontical treatment, a new oral hygiene orientation may be needed to finally establish the follow-up of the patient according to the risk of periodontal disease.

Comparative study on direct and indirect bracket bonding techniques regarding time length and bracket detachment

OBJECTIVE: The aim of this study was to assess the time spent for direct (DBB - direct bracket bonding) and indirect (IBB - indirect bracket bonding) bracket bonding techniques. The time length of laboratorial (IBB) and clinical steps (DBB and IBB) as well as the prevalence of loose bracket after a 24-week follow-up were evaluated. METHODS: Seventeen patients (7 men and 10 women) with a mean age of 21 years, requiring orthodontic treatment were selected for this study. A total of 304 brackets were used (151 DBB and 153 IBB). The same bracket type and bonding material were used in both groups. Data were submitted to statistical analysis by Wilcoxon non-parametric test at 5% level of significance. RESULTS: Considering the total time length, the IBB technique was more time-consuming than the DBB (p < 0.001). However, considering only the clinical phase, the IBB took less time than the DBB (p < 0.001). There was no significant difference (p = 0.910) for the time spent during laboratorial positioning of the brackets and clinical session for IBB in comparison to the clinical procedure for DBB. Additionally, no difference was found as for the prevalence of loose bracket between both groups. CONCLUSION: the IBB can be suggested as a valid clinical procedure since the clinical session was faster and the total time spent for laboratorial positioning of the brackets and clinical procedure was similar to that of DBB. In addition, both approaches resulted in similar frequency of loose bracket.

Orthognathic Surgery in Patients With Cleidocranial Dysplasia

The aim of this study was to report the orthodontic-surgical approach of a 21-year-old female patient diagnosed with cleidocranial dysplasia. An orthognathic surgery was performed in the maxilla and mandible during the same procedure to correct an existing dentofacial deformity (class III malocclusion). In addition, malar prostheses were used to correct midface deficiency. After surgical intervention, orthodontic treatment continued in order to promote stability, function, and aesthetics. Cases of cleidocranial dysplasia treated with the defined criteria can bring aesthetic and functional benefits to the patient.

Estudo da estabilidade da cirurgia do tipo sagital da mandíbula com vista a correção de deformidades faciais

This research evaluated the surgical stabilily in patients with mandibular prognathism and retrognathism in which was used sagital split technic to correct those detormities. Twelve patients were selected from the clinic of only one experienced surgeon. Six patients presenter a Class III 6 a Class II molar relationship. A comparative cefalometric analysis using linear and angular measurements was performed of pre-surgery, imediate pós-surgery and 1 year follow-up. The following conclusions were obtained. 1 The Dal Pont sagital split technic modified by Epker to correct mandibular prognathisn and retroghnatism is a stable technic and must be indicated to correct those deformities. 2 Small relapses are easily corrected by the post-surgical orthodontic treatment. 3 A small over correction is advised in cases of large mandibular advancements or set bascks. 4 In those cases which a large amount of mandibular retrusion on advancement need to be performed, a combination of maxillary and mandibular surgery should be used. Rigid fixation technic is also indicated in those cases

Aplicação da análise de jarabak, no estudo da relação entre a altura total facial anterior e posterior, em pacientes portadores de má-oclusão de classe I e classe II divisão 1 de angle, por meio de radiografias cefalométricas

ln order to predict the facial growth using Jarahak's analysis, cephalometric radiographies of 120 subjects during the mixed dentition and between 6 and 10 years of age were studied. From the total, 60 subjects (30 males and 30 females) were classified as Angle's Class I and 60 subjects (30 males and 30 females) were classified as Angle's Class II, Division 1. AIl subjects did not receive any orthodontic treatment. The proportion between anterior and posterior facial heigth (SGo-NMe) was studied, which is determined by the formula PFH x 100/ AFH = %, neither being straight (> 62% < 65), clockwise ( > 58% < 62%) and anti-clockwise ( > 65% - 80%). Mean average, standard deviation and facial height proportion (SGo - NMe) were determined for males and females according to Angle's classification of malocc!usion. Sexual dimorphism was examined with regard to different types of Angle's malocclusion and the direction of the facial growth, and the correlation of four cephalometrics measurements were analvsed

Aspectos oclusais na etiologia das desordenstemporomandibulares

Since the occlusion area is presented in almost all specialties of Dentistry, its relationship with the health of the patient has been shown. The etiology of temporomandibular disorders is multifactorial and the occlusion is considered an etiologic factor. This study aimed to discuss the functional occlusion aspects and the presence of temporomandibular disorders. Literature Review: The loss of orthopedic balance can induce temporomandibular disorder. Therefore, both the physiological and functional occlusions have been analyzed as a dental relation. Several functional occlusal factors have been linked to the temporomandibular disorders such as deviations of centric relation to maximum intercuspation, occlusal interferences, absence of posterior teeth, changes on the occlusion vertical dimension, malocclusion, orthodontic treatment and parafunction. Conclusion: The most common occlusal factors related to temporomandibular disorders are quite frequent; however, the diagnosis and treatment of such disorders should be considered individually

Ocorrência de reabsorção radicular no tratamento ortodôntico: revisão crítica da literatura

The root resorption is one of the possible sequels of greater complexity to the orthodontist, the difficulty of detection and be asymptomatic. The presence, during the orthodontic treatment, is linked to a multifactorial origin, a complex combination of biological activities, anatomical, physiological, genetic variables and mechanical forces. Thus, the aim of this study was perform to critical literature review related to root resorption in orthodontic movement. Were included articles published between 2004 to 2014, indexed in the PUBMED database. Used descriptors contained in the Mesh, being adopted as inclusion criteria: clinical trials in humans, only articles that had clear ideas and objective, articles with English language. The search strategy used resulted in 24 articles and after applied the inclusion and exclusion criteria, 11 articles remained. Based on the results of this study it was concluded that heavy forces of intrusion, inclination and torque leads to a greater degree of root resorption; its etiology is multifactorial, the periodic radiographic control during treatment is needed and further studies are suggested to identify more specifically the causes and risk factors for root resorption.

Fios ortodônticos superelásticos e sua aplicabilidade na clínica ortodôntica: revisão da literatura

During clinical routine, the orthodontist uses several materials, which include metallic alloys in the form of metallic wires. However, it is necessary that the professional has some knowledge of the properties of those wires. Different types of wires are commercially available: stainless steel wires, chrome-cobalt wires, nickel-titanium wires and beta-titanium wires. Among the nickel-titanium wires, there are three subdivisions: a conventional alloy and two superelastic alloys. The superelasticity, associated to the effect of form memory, is a property used in orthodontics to initiate the dental movement in the first phase of the orthodontic treatment. This property is considered to be biologically compatible with the effective dental movement. These wires are available at the market in different transformation temperatures, and they offer the best adaptation in the groove of the bracket, simplicity and a faster treatment. However, they present little formability, and they don’t accept solder. They are also more onerous than other wires. Moreover, the low rigidity of these wires doesn’t allow them to be used for the retraction of the anterior teeth or closing of spaces. Therefore, the coherent use of superelastic orthodontic wires is recommended, accompanied by a detailed diagnosis and planning, so the result will be an efficient orthodontic correction, accomplished in a shorter period of time.

O momento oportuno para a abordagem ortodontica no tratamento da classe II

Because it still brings polemic among the professionals, it was mention once more, in this literature review, the theme that aims to define the appropriate timing to approach the bad occlusions of Class II, and also when it would the right opportunity to treat them, in way that would convey to the patient consistent, stable results in a long term. These are important aspects to be taken into consideration by orthodontists, either by those who defend the early treatment or by those who defend the late treatment. Therefore, the present study aims to aid the clarification of daily doubts regarding this aspect.
