Resolução estética associando prótese sobre implante e prótese convencional na região anterior

The combination of several methods for solving aesthetics in a clinical case can be a complicating factor. The diagnosis and planning of the event held in conjunction with the dental technician expand the possibilities of success. The present case illustrates the aesthetic resolution through the association of implant- and tooth-supported prostheses using metal free ceramic systems. A 38-year old male patient presented with a complex smile. After diagnosis and treatment planning, two ceramic crowns were made, one on tooth 11 and one on the implant region 21, along with a laminated porcelain veneer on the region of 12. Aesthetic needs of the patient are predictable only with a sound diagnosis.

Plástica gengival associada à laminados cerâmicos para resolução estética

Sometimes we face clinical situations in which the lack of harmony in the smile is caused by a major exhibition of the gingival tissue. In these cases the professional should be able to perform a detailed analysis of the static and dynamic components of the smile, in search of a satisfactory planning and treatment which may include different dental specialties. For these situations, the association of periodontics/prosthesis is a viable alternative that has been used positively in search of an aesthetic and functional condition that benefits the patient, without leaving aside the preservation of periodontal tissues and of the remaining structure of the tooth. Thus, the aim of this study was to describe a case in which the association between these two areas was proposed to correct gummy smile and dental vestibularization. Clinical results and the satisfaction of the patient indicate that this multidisciplinary treatment combining periodontal and prosthetic techniques is favorable to positive results in cases of compromised smile aesthetics due to excessive gum tissue.

Reabilitação estética com enfoque nas diferentes cores de substratos e na escolha da cor do cimento adesivo

The evolution of techniques and materials applied to adhesive ceramic restorations resulted in the intensification of its use, proving to be an excellent method of aesthetic restoration. Some important features of this technique are its conservative preparation, which avoids an excessive loss of tooth structure and its high aesthetic value provided by the ceramic even when utilized under different color of dental substrates. The aim of this paper was to report a clinical case with full crowns, porcelain veneers and non-prep veneers, enhancing peculiarities related to the material used, tooth preparation techniques, cementing, indications and contraindications.

Tratamento compensatorio da má oclusnao de classe lll: revisão de literatura

Class III malocclusion is less common occlusal relationship, covering less than 5% of the population. There are various forms of treatment in Class III malocclusion. Depending on how the form is expressed Class III and age of the patient, the therapy may be orthopedic and orthodontic surgical orthodontics. The objective was to review the literature of the last 10 years about ways to compensatory treatment of Class III malocclusion. Several articles were published between 04/2003 and 04/2013 in the Pubmed database from the keyword "Class III malocclusion". However, only 19 articles that addressed the compensatory treatment of Class III were selected. Based on the selected items it was concluded that the treatment of Class III malocclusions in children before the peak of pubertal growth has better prognosis with greater effects orthopedic and orthodontic minor effects. The ideal treatment option for this condition is the Rapid maxillary expansion associated with maxillary protraction of the same. The treatment of Class III malocclusion in young people after the peak of pubertal growth is doubtful prognosis. You can opt to treat rapid maxillary expansion and maxillary protraction of the same or fixed appliance, however, orthopedic effects can be the same or smaller than the orthodontic effects, depending on the age of the patient. Depending on the degree of Class III malocclusion in adults, the treatment will consist of dental compensations or orthognathic surgery.

Case report: Cornelia de Lange Syndrome (CDLS)

The Cornélia of Lange´s syndrome is a genetic anomaly, described and published by Cornelia Catharina of Lange in 1933, however, their aspects were described previously by Winfried Robert Clemens Brechmann in 1916, that’s why it is also known as Brachmann of Lange’s syndrome. The most frequent clinical characteristics include typical face dismorfia, variable degree of mental delay, anomalies of the hands and feet, multiple malformations, retardation of the pre and postnatal physical development and microcephaly variable intellectual compromising. Some facial characteristics are peculiar and they are mixed with the inherited lines of their own family, the united brows, the long lashes, the small nose, the round face, the fine lips and lightly inverted. As oral manifestations they present micrognathia, dental crowding, periodontal disease, delayed dental eruption, enamel hypoplasia, erosion of the enamel and dentine caused by stomach acids of the gastroesophageal reflux and atresia of the dental arches. The purpose of this paper is to present a clinical report of a boy bearer of this syndrome assisted at CAOE - FOA - UNESP, emphasizing the importance of multiprofessional team for the diagnosis and treatment of this syndrome.

Odontoma em pacientes odontopediátrico: diagnóstico e tratamento. Relato de caso clínico.

Odontoma is a term that refers to a benign tumor of odontogenic and mixed nature, composed of epithelial and mesenchymal components. Histologically, they are compounds of different configurations including dental enamel, dentin, cementum and in some cases the pulp tissue. A slow growing asymptomatic tumor, odontoma is usually discovered through routine radiographic examination. A 3-year old male patient sought care at the School of Dentistry’s Baby Clinic (UNESP-Araçatuba), complaining of “small ball close to the teeth.” During the interview, the mother reported that the lesion was observed soon after a trauma, and evolved in less than one month. An ulcerated lesion with a 0.8 cm diameter was found during intraoral clinical examination. It was located in the inferior and anterior region of the mouth, between teeth 81 and 82, and there was also crown distalization. A radiographic examination showed a radiolucent area and root distance. In the absence of clinical and radiographic characteristics suggesting a case of odontoma, the differential diagnosis was peripheral giant cell lesion and pyogenic granuloma. So the area was punctured. Nonetheless, due to the absence of liquid, the surgical removal of the lesion was performed, followed by histological examination, which showed the definite diagnosis of a suggestive case of emerging odontoma.

A utilização do diagrama individual anatômico objetivo (DIAO) no contorneameento de arcos ortodônticos

A morfologia das arcadas dentárias sobre as bases ósseas é conseguida utilizando-se fios ortodônticos, os quais detêm o potencial de correção das irregularidades dentárias. O presente artigo discute conceitos acerca da morfologia das arcadas dentárias, bem como demonstra a utilização do Diagrama Individual Anatômico Objetivo (DIAO). A premissa básica para o contorneamento dos arcos de nivelamento reside na individualização da forma da arcada dentária, que deve considerar as bases ósseas e o relacionamento entre elas, bem como os objetivos terapêuticos. O contorneamento dos arcos de nivelamento baseado no diagrama individualizado torna prática a rotina ortodôntica por favorecer a constância de forma e garantir a simetria da arcada dentária.

Avaliação dos preparos da superfície cerâmica para a colagem de acessórios ortodônticos

The purpose of this study was to evaluate the effects of two conditioning methods used to enhance the shear strength of orthodontic brackets bonded to porcelain surfaces. A total of 18 feldspathic specimens were used. The specimens were divided randomly into two groups (n = 9): group free silane, the porcelain specimens were etched with hidrofuoric acid 10% (Acid Gel-Maquira) for 4 minutes followed by adhesive-primer (Transbond XT) and the metallic brackets (Morelli Roth Light .022" x .030") were bonded with a light-cured microfilled resin (Transbond XT Light Cure Orthodontic Adhesive); group silane, the porcelain specimens were etched with hidrofuoric acid 10% (Acid Gel-Maquira) for 4 minutes followed by silane (Silano Ângelus) for 1 minute, adhesive-primer (Transbond XT) and the metallic brackets (Morelli Roth Light .022" x .030") were bonded with a light-cured microfilled resin (Transbond XT Light Cure Orthodontic Adhesive). All specimens were stored in solution of artificial saliva at ambient temperature for 24 hours. The debonding was done with shear strength through a universal testing machine (DL 500-Emic) calibrated with a fixed speed of 1mm/minute. Statical analysis was performed using the Student t test. The results indicated that in the free silane group the mean bond strength was 9,97 MPA, significantly lower than the silane group, that was 12,38 MPa (p < 0,05). The both groups were effective for bonding, although the silane group had the highest bond strength values.

Giroversão dental: formação de imagem radiográfica virtual

Entre as diversas anomalias dentárias, a giroversão dental constitui uma anomalia de grande prevalência, na qual o dente realiza rotação em torno do seu próprio eixo. No exame radiográfico panorâmico é possível verificar a presença de giroversão, porém, quando a dinâmica de giro do eixo do equipamento não coincide com a curvatura da maxila e mandíbula, a imagem dos dentes apresenta-se girovertida ou com apinhamento dental. O presente trabalho teve por objetivo avaliar se as giroversões dentais presentes nas radiografias panorâmicas são verdadeiras ou apenas “virtuais”. Foram selecionadas 71 radiografias panorâmicas com imagens sugestivas de dentes girovertidos, de pacientes que também possuíam a documentação da cavidade bucal por fotografia e modelo de estudo. A média de idade dos pacientes avaliados foi 15 anos de idade. A imagem radiográfica panorâmica, fotografia e modelo de estudo foram avaliadas por um único examinador. Na avaliação das radiografias panorâmicas foram encontradas 246 dentes girovertidos. Porém, ao avaliar a fotografia e o modelo de estudo destes pacientes comprovou-se apenas 127 dentes com giroversão. Estes resultados indicam uma correspondência clinica/radiográfica de 51,4 %, ou seja, 48,6% das giroversões identificadas radiograficamente, eram “virtuais”. Pode-se concluir que o diagnóstico de giroversão dental utilizando a radiografia panorâmica deve ser confirmado pelo exame clínico para evitar diagnósticos falsos positivos.

Avaliação histológica da ação da raioterapia na região odontogênica de incisivos de ratos

Inúmeras alterações dentárias podem ocorrer em crianças submetidas ao tratamento radioterápico. O objetivo neste trabalho foi avaliar histologicamente a ação da radiação X na região odontogênica do incisivo inferior de ratos com doses de 5 e 15 Gy. Foram utilizados 30 ratos machos (Rattus norvegicus, Albinus, Wistar), os quais foram divididos em três grupos: controle; radioterapia 5 Gy (irradiados com 5 Gy); e grupo 15 Gy (irradiados com 15 Gy). As doses foram administradas na região de cabeça e pescoço, em dose única, no segundo dia do experimento. As mandíbulas foram preparadas em lâminas histológicas. Na porção inicial da região odontogênica do grupo 5 Gy, os odontoblastos apresentaram-se alterados morfologicamente e menos organizados. Já no grupo 15 Gy foram observadas irregularidades na organização dos odontoblastos e ameloblastos, além de alteração na formação da alça epitelial e hemorragia. Na porção média da região odontogênica, o grupo 5 Gy apresentou alterações na face lingual, bem como leves alterações nos odontoblastos na região distal do dente; o órgão dentário do grupo 15 Gy apresentou visível redução do tamanho, hemorragia, odontoblastos não polarizados e produção de dentina para diferentes direções; observando-se ainda na porção distal, extensa destruição com visível redução no tamanho e vasta desorganização nos odontoblastos e ameloblastos. Conclui-se que a dose de 5 Gy causou leves e pequenas alterações morfológicas, e a dose de 15 Gy provocou intensas alterações histológicas e estruturais na região odontogênica do incisivo de rato.
