Laser-assisted multidisciplinary approach for closure and prevention of relapse of midline diastema.

Midline diastema, which occurs as spacing between the upper central incisors, is a common occurrence seen in the pediatric population. In the ugly duckling stage of development; no treatment is generally advocated as the diastema is a transient one. When diastemas occur due to other pathologies, they pose several problems in relation to esthetics and speech in a growing child. With the advent of time, patient's demand for esthetics has greatly increased. Along with this, a less time-consuming treatment option is a favorite. Proper diagnosis of the diastema, unfolding its etiology, helps in devising an adequate treatment plan. This eventually will lead to stability of the final result. The present case report presents a different and unique approach for the esthetic closure of midline diastema following frenectomy procedure. The approach proves to be a quick and simple option for closure of midline diastemas in cases with concomitant incisal edge irregularities.

Fechamento de diastema com resina composta direta: relato de caso clínico / Diastema closure with direct composite restorations: a case report

Com a evolução dos materiais restauradores adesivos diretos e das técnicas restauradoras minimamente invasivas, é possível realizar o fechamento de diastemas inter incisivos superiores de maneira efetiva e estética em uma única sessão. O presente trabalho consiste em um relato de caso clínico que aborda o clareamento dental e o fechamento de diastema entre os dentes 11 e 21 de um paciente jovem. Previamente ao procedimento restaurador foi realizado clareamento de consultório em todos os dentes com peróxido de hidrogênio 35%. Então, o planejamento restaurador foi auxiliado por modelos de estudo associado ao enceramento diagnóstico.A técnica restauradora de eleição foi a resina composta direta com o auxílio de uma matriz/guia de silicona para a confecção das faces palatinas das restaurações. Após o acabamento e polimento, obteve-se a reanatomização dos incisivos centrais com a eliminação do diastema. O tratamento realizado baseado no clareamento dental seguido por restaurações diretas de resina composta foi eficaz na solução estética do sorriso, atingindo a expectativa do paciente e dentro dos princípios de máxima preservação dos tecidos dentais.

After the evolution of restorative adhesive materials and minimal invasive restorations, it ispossible to close a maxilar interincisal diastema in an effective and aesthetical way, performingit in only one session. This clinical case report approaches a teeth bleaching and diastema closurewith composites between teeth 11 and 21, of a young male patient. The elective restorative technique was direct composite restoration with a silicon putty matrix to make the shape of thelingual surfaces of the restorations. Before the restoration procedure, it was performed “in office”bleaching technique, in addition to the case planning with the assistance of a wax-up. The tooth whitening therapy followed by direct composite restorations was effective, contributing to clinical success, esthetic and patient´s satisfaction.

Principios básicos para el desarrollo de una correcta oclusión / Basic principles for the development of a good occlusion

Se destaca la importancia de prevenir la maloclusión a partir de la aplicación de los principios básicos fundamentales que van desde un consejo y asesoramiento a los padres, continuando con el control del crecimiento y desarrollo del niño y la aplicación de medidas preventivas acordes a los problemas que se presenten, hasta la posibilidad de interceptar un caso precoz de anomalía dentomaxilofacial, a fin de asegurarnos un futuro fisiologismo armónico del sistema estomatognático.

Role of interceptive orthodontics in early mixed dentition.

Early orthodontic interventions are often initiated in the developing dentition to promote favourable developmental changes and remove or suppress those that are unfavourable. Early interceptive orthodontics can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. It also improves self-esteem in the subjects and parental satisfaction. Early detection and appropriate referral of cases requiring interceptive orthodontics are important. However, lack of awareness among school children, parents and primary-care personnel (dental nurses and dental officers) may result in patients not being referred for timely interceptive intervention. This article presents a general view of the scope of interceptive orthodontics that can be carried out in early mixed dentition, i.e. when the permanent incisors and molars are erupting into the oral cavity.

Relación intra-arcada en la dentición temporal:Diastemas, ausencia de diastemas y apiñamiento / Dental arch relationships in the primary dentition: diastemas, absence of diastemas and crowding

La relación intra-arcada fue evaluada en 2.016 niños (1.032 del sexo masculino y 984 del género femenino) de 12 jardines de infancia públicos y de ocho privados del municipio de Bauru en Sâo Paulo, en fase de dentición temporal completa, comprendidos en la franja de edad entre 3 a 6 años. Los espacios constituían la característica dominante en el arco dentario superior (84,57 por ciento) y en el arco dentario inferior (81,25 por ciento) seguidos por la ausencia de diastemas en el arco superior (10,51 por ciento) y en el arco inferior (9,33 por ciento). Un 11,1 por ciento de los niños exhibían apiñamiento en una en ambas arcadas dentarias. El apiñamiento se manifestó aisladamente en las arcadas superior, inferior y en ambas con una prevalencia del 1,68 por ciento, 6,20 por ciento y 3,22 por ciento, respectivamente. Este comportamiento intraarcadas fue semejante en el grupo seleccionado de niños con oclusión normal, en las que predominó el arco con diastemas seguido por el arco sin diastemas y por el arco con apiñamiento. Un 6,68 por ciento de los niños con oclusión normal presentaban apiñamiento. La prevalencia de apiñamiento entre los niños con oclusión normal fue del 0,18 por ciento para el arco dentario superior, del 5,94 por ciento para el arco dentario inferior y del 0,56 por ciento para ambos arcos dentarios.

Proximal contact formation with different restorative materials and techniques.

PURPOSE: To determine, whether different tooth colored materials and application techniques influence the proximal contact strengths (PCS) in vitro. MATERIALS AND METHODS: Standardized MO-cavities for direct restorations were prepared into 360 artificial lower first molars. Eight groups were formed (n = 45) and restored with amalgam (1), low (2, 3), medium (4, 5) and high (6, 7) viscosity hybrid composites and compared to the original contact strengths of the unprepared teeth (8). The restored teeth were mounted into a socket simulating physiological tooth mobility. PCS were quantified by measuring the forces necessary for passing the proximal contact with floss under standardized conditions using a universal testing machine. RESULTS: PCS ranged from 1.32 +/- 0.56 N for the low viscosity composite to 9.90 +/- 1.98 N for the Amalgam restoration. Medium (5.65 +/- 1.08 N) and high viscosity hybrid composites (5.90 +/- 1.45 N) inserted in a multi-layer technique showed no statistically significant differences to the original PCS of the unprepared teeth (5.76 +/- 0.53 N).

La práctica de la Odontología debe estar siempre en manos del profesional odontólogo y que él por lo tanto debe ser capaz de brindar ese servicio, conocer la presencia del hueso premaxilar y la influencia de la sutura en la línea media como nueva causa para la presencia del diastema interincisivo central superior, prvocando un espacio antómico entre dos dientes vecinos que impide el apoyo coronario mesiodistal, cuando éstos se encuentran correctamente erupcionados y alineados formando el sector anterior del arco dentario. Lo que ha permitido precisar, como tema actual y necesario a investigar: "EL DIASTEMA INTERINCISIVO CENTRAL SUPERIOR". Sobre la base temática se determinó el siguiente: PROBLEMA: Cómo influye la fusión imperfecta en línea media de los maxilares en la etiología del diastema interincisivo central superior? OBJETO DE ESTUDIO: El sector alveolar anterior de los huesos maxilares superiores. OBJETIVO: Demostrar la presencia de fusión imperfecta en la línea media de los maxilares superiores como causa etiológica del diastema interincisivo central superior

An effective technique for extended proximal contacts in composite resin restorations.

Obtaining a firm anatomic contact has been a difficult criteria in placing Class II posterior composite restorations. Various techniques have been developed and a number of products marketed to accomplish this task, but none have combined the necessary qualifications of ease, simplicity, and effectiveness for consistent and predictable results. To address this challenge, two innovative devices--a precontoured (biplanar concave) sectional matrix band and a light--focusing tip-have been developed. Using a clinical case presentation, this article describes the application of these devices to obtain high quality proximal contacts, even in widely separated teeth. The learning objective of this article is to familiarize clinicians with this procedure. The technique is simple and universally applicable with a variety of posterior composite materials and placement methods.

Surgically assisted rapid palatal expansion: a modified approach in a patient with a missing lateral incisor.

In conventional surgically assisted rapid palatal expansion, a diastema is opened between the central incisors. A case is presented in which the surgical procedure was modified so that the split of the maxilla occurred in the region of a missing lateral incisor rather than at the midline. This facilitated restoration of the space with a prosthetic tooth almost immediately following surgery.
