Eficiência do aparelho Herbst bandado na correção da Classe II divisão 1 -relato de caso

The current reports the case of a young patient with malocclusion Class II division 1 on permanent dentition treated in two stages, rthopedics and orthodontics, respectively. At first, the banded Herbst appliance was used duringa 7 months period, followed by a T4K appliance, Trainer for Kids used as retention, and on the second stage the corrective Orthodontics was performed. The results showed the acquirement of a Class I dental relationship, which was kept stable, with excellent intercuspation, even after 5 years of the removal of the Herbst appliance, as well as the correction of the overjet and the reduction of the facial profile convexity. It can be concluded that the Herbst appliance was very efficient in correcting the Class II malocclusion, long term, also providing a very favorable effect on the facial profile.

Alterações dimensionais em pacientes submetidos à expansão rápida da maxila com aparelho do tipo Haas

The maxillary atresia is a alteration in the transverse dimension that can result in a unilateral or bilateral crossbite. For correction of atresia of the upper dental arch appliances with the intent to expand the arch of orthopedic or orthodontic manner are used, obtaining across-compatibility between the dental arches. The purpose of this study was to evaluate the dimensional changes of the maxillary in patients in the mixed dentition with atresia in the upper dental arch, using occlusal radiographs taken before, after rapid maxillary expansion and after removal of the appliance. Methods: the sample consisted of 35 patients who used the appliance type conventional Haas, in the mixed dentition, according to the standard protocol for installation, activation, containment and removal of the appliances rapid maxillary expansion. Results: the results confirm that the suture opening occurs in greater quantities in the anterior (4.3 mm) than posterior to (3.74 mm), representing a triangular opening of 7 degrees on average with the posterior opening 87% of the quantity of anterior opening. The molars region expanded about 5 mm, and the base bone 3.7 mm, representing a 74% bone expansion of the expansion teeth.

Extração seriada: considerações clínicas

The early malocclusion treatment has increased interest of orthodontic community. Among these is the serial extraction that harmonizes the differences between the amount of dental material and permanent deficiency of supporting bone. The technique is applied in mixed dentition through a predetermined sequence of extractions between deciduous and permanent teeth, in order to reach spontaneous immediately alignment of remaining permanent teeth with a minimum orthodontic mechanics. It will be reported a case where the serial extraction was performed in a growing patient with biprotrusion, Class I malocclusion and severe crowding. All functional and aesthetics goals were reached.

Parâmetros de força ideal aplicada aos principais movimenetos ortodônticos

The orthodontic movement is a result of the system of forces application and it depends on the response of periodontal tissues to this system. The forces must have a magnitude considered ideal, to has maximum response of tissue without pain or root resorption, and keep the health of the periodontal ligament, during all the tooth movement. Therefore, it seems adequate by means of an available literature to estimate parameters of ideal force, for different types of movements; with intention of assisting the orthodontists in optimum control of the tooth movement and thus to diminish the possibility to generate deleterious effects.

Aplicação clínica da mola T do grupo B para retração dos dentes anteriores

A TAS (Técnica do Arco Segmentado) representa uma alternativa à mecânica de deslizamento, muitas vezes dificultada pela incerteza da quantidade de força de atrito envolvida em cada sistema de forças utilizado. Nesse contexto, sabe-se que poucos cursos de Ortodontia no Brasil têm ensinado efetivamente a filosofia e o modo de trabalhar com a TAS. Portanto, este trabalho procura elucidar a forma de raciocínio das relaçÕes entre força e momento manipuladas na TAS, bem como mostrar a forma de confecção e utilização de mola "T" do grupo B, onde objetiva-se a movimentação recíproca dos segmentos posterior e anterior e, por fim, apresentar um caso clínico tratado com esse tipo de mecânica.

Ertty System®: distalização segmentar

Introduction: Ertty System® is an intraoral system of biomechanical forces to move teeth anteroposteriorly. The application of forces on this system results in the distalization of the molar and all lateral segment in the side to be distalized, including premolars and canine, resulting in alveolar bone remodeling. This system is indicated to correct uni- or bilateral maxillary dental Class II malocclusion in permanent dentition both in children and adults. It is contraindicated in case of skeletal asymmetries, protrusion of maxillary and mandibular teeth, skeletal Class II and Class II subdivision malocclusions with mandibular midline deviation. This study describes Ertty System® and presents two clinical cases treated using this system. The two female patients presented with Class II malocclusion subdivision and maxillary midline deviation. Results: It was achieved correct alignment and leveling, Class I dental relation and correction of upper midline. Conclusion: The success and stability of results confirmed diagnosis and treatment adequacy.

Tratamento ortodôntico lingual individualizado com o sistema Incognito

Introduction: The orthodontic treatment using lingual brackets has been desired by adult patients for esthetic factors. In this paper it is described the clinical steps of an orthodontic treatment using Incognito™ system, individualized lingual brackets and archwires designed by CAD/CAM technology. Methods: The presented case describes the treatment of a patient with mesofacial growth pattern,Class I malocclusion, with mandibular crowding and diastema between the upper central incisors, treated using 100% individualized lingual brackets. Results: After treatment, the molar relation of Class I was kept, the spaces between upper central incisors were closed and mandibular crowding corrected. Conclusion: This case report demonstrated the efficiency of the new method for lingual orthodontic treatment.

Reabilitação oral de paciente com síndrome da combinação: relato de caso

The Combination Syndrome represents an important pathologic condition of the masticatory system that requires a complex rehabilitation treatment. The presence of flaccid mucosa is one of the most common features due to bone resorption of the pre-maxilla caused by anterior hyperfunction of the mandibular teeth on the maxillary complete denture, where the impact of oclusal loading in this region results in movement of the maxillary prosthesis into the ridge, resulting in increased resorption of the residual ridge, internal misfit and loss of the retention of the maxillary complete denture. The presence of flaccid mucosa, in such cases, leads to problems of support and stability of the maxillary complete denture, which can be treated by surgical reduction of the thickness of the tissue or using specific techniques of fabrication of prostheses. This article describes the oral rehabilitation of a patient with the Combination Syndrome where the surgical reduction of flaccid mucosa was not performed, using a modified technique of functional impression in two steps, with the objective of generating forces and less distortion in flaccid mucosa during functional impression.

Estudo prospectivo sobre a utilização de próteses totais implantossuportadas em pacientes edêntulos

The objective of this study was to evaluate the impact of replacing conventional mandibular complete dentures by complete fixed dentures on the oral health-related quality of life and kinesiographic parameters of maxillary edentulous patients. Material and Methods: edentulous patients (n = 16) received one set of new complete dentures and after the intraoral adjustments and adaptation period (30 days), the Brazilian version of Oral Health Impact Profile for assessing edentulous subjects (Ohip-Edent) was used to evaluate the oral health-related quality of life (OHQOL) of the participants. Additionally, the kinesiograph instrument K6-I (Myotronics Research Inc., Seattle, WA) was used to record opening and closure range of movement, mandibular movement, and the pattern of maxillary complete denture movement on chewing. Afterwards, the patients had their mandibular complete dentures replaced by a complete fixed denture and the same evaluation protocol was performed after 3 and 6 months. Ohip-Edent responses were analyzed using Wilcoxon's test for repeated measures (α = .05) and Kinesiographic data using the Student´s t test (α = .05). Results: The Ohip-Edent showed an improvement of general oral health-related quality of life after 3 and 6 months of the treatment with complete fixed dentures. Kinesiographic recordings revealed a significant increase on maximum mandibular movements of vertical opening and no differences for the movement of the maxillary complete denture on chewing after treatment with complete fixed dentures was observed. Conclusion: the installation of complete fixed dentures improved the OHQOL and changed mandibular movements, with increases in vertical amplitude of maximal opening.
