Midline diastema closure using a lithium disilicate glass ceramic fragment: increased long-term color stability"

ABSTRACT: Nowadays, maxillary midline diastema (MMD) can be treated with different multidisciplinary approaches. When restorative dentistry is needed, glass-matrix ceramic materials is one of the best choices, since they present good optical behavior and high survival rates in the anterior dentition. To obtain an adequate interphase, and color integration are one of the main restorative goals, and for that purpose, specific finishing and polishing procedures must be employed to avoid staining and ensure the restoration's color stability. In the case report presented in this article, a single lithium disilicate ceramic fragment was performed to close a MMD produced by the shape alteration of one of the maxillary central incisors. Also, the finishing and polishing procedure is discussed.

Longitudinal evaluation of diastema closure in patients submitted to labial frenectomy in different phases of the mixed dentition A historical cohort

Background: There is a controversy in the literature concerning the indications for frenectomy to treat interincisal diastema. Aims and Objectives: The aim of this study was to evaluate the spontaneous closure of the interincisal diastema in patients submitted to upper labial frenectomy (ULF) during the mixed dentition. Materials and Methods: Records from patients treated between 2009 and 2014 in the course of Pediatric Dentistry Surgery at Fundecto–USP were evaluated to select those that were submitted to ULF during the mixed dentition using the Chelotti technique. Initial clinic characteristics and radiographic data related to the abnormal upper labial frenum were collected. The patients were called for a return visit to evaluate the diastema closure. The prevalence of children with diastema reduction after the frenectomy was determined by descriptive analysis. Logistic regression was used to evaluate the association between exposure factors and diastema reduction. Results: From 449 eligible records, 53 were selected and 25 were in a return visit. It was not possible to find association between the exposure factors and diastema closure. Conclusion: There is no relation between the time of surgery intervention and diastema closure. However, the intervention during the mixed dentition led to a partial diastema reduction in 80% of the cases.

The use of direct composite resin to close maxillary midline diastema complementary to orthodontic treatment

ABSTRACT: The maxillary midline diastema is a common esthetic problem in patients. Assess and diagnose may be challenging due to the many factors that influences the alteration of tooth eruption process and tooth shape. Due to the various advantages and the reversibility of treatments, composite resins are today a suitable aesthetic and functional option, even so, its management and technique require a trained and experienced clinician in order to obtain an optimal outcome. The following report, is a clinical case of a 21-year old female with a main complaint of a maxillary midline diastema produced by the alteration in tooth shape and size of both upper central incisors, which was closed and corrected with direct composite resins.

Conservative and esthetic closure of maxillary midline diastema without creating "black triangle" using direct resin composite

Anterior diastemas are common esthetic problems. One of the challenges in clinical esthetic dentistry is closing anterior diastemas without creating “black triangles” between the teeth. The success of a restorative treatment in anterior teeth depends on the esthetic integration between soft tissues and hard tissues. This report describes the successfully accomplished diastema closure case by producing the emergence profile with natural contours at the gingival-tooth interface and then generating of gingival recontouring process.

Rehabilitación estética con carillas de disilicato de litio / Esthetic rehabilitation with lithium disilicate veneers

Debido a sus resultados estéticos y a la máxima conservación de la estructura dentaria, las carillas de disilicato de litio se encuentran indicadas para el tratamiento estético de los dientes anteriores que tengan anomalía en la forma, tamaño y color. El objetivo de este caso es demostrar los pasos en la rehabilitación utilizando carillas de disilicato de litio. El paciente presenta diastemas desde los dientes 15 a 25, se realizo el examen clínico general y oral, se obtuvieron los modelos de estudio, se realizo el encerado diagnóstico en base al DSD y se confeccionó el Mock up con silicona de adición; el laboratorio fabrico las carillas en disilicato de litio y se cementaron con técnica adhesiva. Las carillas permitieron un tratamiento rehabilitador conservador, funcional y estético de nuestro paciente

Because the aesthetic results and preservation of tooth structure, lithium disilicate veneers are indicated for the aesthetic treatment of anterior teeth with abnormal shape, size and color. The aim of this report was to demonstrate the steps in oral rehabilitation using lithium disilicate veneers. The patient had teeth diastemas from 15 to 25; general and oral clinical examination was performed, and study models were obtained. waxed diagnosis was made based on the DSD and Mockup was drawn with addition silicone; the laboratory fabricate veneers lithium disilicate were cemented by adhesive technique. Veneers allowed a conservative, functional and aesthetic rehabilitation treatment of our patient

Diastema closure using direct bonding restorations combined with orthodontic treatment: a case report

Closure of interdental spaces using proximal build-ups with resin composite is considered to be practical and conservative. However, a comprehensive approach combining two or more treatment modalities may be needed to improve esthetics. This case report describes the management of a patient with multiple diastemas, a peg-shaped lateral incisor and midline deviation in the maxillary anterior area. Direct resin bonding along with orthodontic movement of teeth allows space closure and midline correction, consequently, creating a better esthetic result.

Diastema closure with direct composite: architectural gingival contouring / 대한치과보존학회지

One of the most challenging task in closing anterior diastema is avoiding "black triangle" between the teeth. This paper reports a case that the closure of diastema in anterior teeth could be successfully accomplished using direct adhesive restorations and gingival recontouring. The traditional technique using Mylar strip was modified to increase the emergence profile with natural contours at the gingival-tooth interface. Mylar strip was extended out of the sulcus by approximately 1 mm high from the gingival margin, and a small cotton pellet was used to provide the emergence contour. This modified approach is acceptable for the clinical situation.
