ABSTRACT
La pérdida de superficie dental se define como una condición en la que el desgaste de la estructura dental es excesivo según la edad. Esta pérdida patológica se relaciona comúnmente con una combinación de factores como erosión, abrasión, atricción o parafunción. La técnica de Dahl es una alternativa válida que resuelve los inconvenientes surgidos en este tipo de situaciones como ser la compensación dentoalveolar. Este caso corresponde a un paciente de 63 años que acudió al Hospital Dental de la Universidad de Manchester, derivado por su odontólogo particular. Al momento del examen clínico se constató pérdida moderada a severa de la superficie dental palatina e incisal localizada en el sector anterior de los dientes, sobremordida profunda y compensación alveolar dental. Fueron realizadas restauraciones directas a mano alzada de canino a canino. Luego del relleno incisal se constató una mordida abierta posterior de aproximadamente 1 a 1,5 mm. El contacto oclusal posterior fue restablecido totalmente en 3 meses.
A perda da superfície dentária é definida como uma condição em que o desgaste da estrutura dentária é excessivo de acordo com a idade, essa perda patológica está comumente relacionada a uma combinação de fatores, sendo eles: erosão, abrasão, atrito ou parafunção. Uma abordagem restauradora nestas situações representa um desafio para a reabilitação oral principalmente pela Compensação dentoalveolar. A técnica de Dahl é uma alternativa válida para resolver este problema. Este caso corresponde a um paciente de 63 anos que procurou o Hospital Odontológico da Universidade de Manchester, encaminhado por seu dentista particular. No momento do exame clínico, observou-se perda moderada da superfície dentária no setor anterior, sobremordida profunda e compensação alveolar dentária. Foram realizadas restaurações diretas da mão livre do canino para o canino. Após o enchimento incisal, observou-se mordida aberta posterior de aproximadamente 1 a 1,5 mm. O contato oclusal total foi restabelecido em 3 meses.
Tooth Surface Loss (TSL) is defined as a condition in which the wear of the tooth structure is excessive according to age. This pathological loss is commonly related to a combination of factors such as erosion, abrasion, attrition, or parafunction. The Dahl technique is a valid alternative that solves the problems that arise in this type of situation, such as dentoalveolar compensation. This case describes a 63-year-old patient who attended the Dental Hospital of the University of Manchester, referred by his private dentist. At the time of the clinical examination, moderate to severe loss of the palatal and incisal tooth surface located in the anterior sector of the teeth, deep overbite and dental alveolar compensation were found. Direct free-hand restorations were performed from canine to canine. After incisal filling, a posterior open bite of approximately 1 to 1.5 mm was observed. Posterior occlusal contact was completely restored in 3 months.
ABSTRACT
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.

“Dental fluorosis,” a specific disturbance in tooth formation and an esthetic condition, is defined as a chronic, fluorideinduced condition, in which enamel development is disrupted and the enamel is hypomineralized. Fluorosis can be prevented by having an adequate knowledge of the fluoride sources, knowing how to manage this issue and therefore, avoid overexposure. Controlling the fluoride intake is the best preventive measure for dental fluorosis, however when this is already installed and causing esthetic problems to the patient, many treatment techniques are recommended. This article describes an esthetic rehabilitation of a case of severe fluorosis using a new system for placing direct composite veneer, the Uveneer System (Ultradent) which simulates predictable shape and symmetry of natural teeth. In cases of severe dental fluorosis, the tooth enamel usually becomes porous and tooth whitening methods are not recommended. Therefore, minimally invasive technique of direct composite veneering using facial templates is the treatment of choice as it is easy to use, enhance clinical productivity, saves time, requires minimal preparation and is cost effective.
ABSTRACT
Dental fluorosis is a condition of enamel hypo-mineralization due to the effects of excessive fluoride on ameloblasts during enamel formation. Bonding brackets to fluorosed teeth remains a notable clinical challenge because of frequent bracket failure at the compromised enamel interface. This case report presents comprehensive management of an adult patient with Angle’s class II div 1 malocclusion with crowding and severe dental fluorosis. Diagnosis: A diagnosis of severe dental flourosis was established based on Deans‘s index for fluorosis (score-3) with a skeletal Class I pattern and Angle’ s Class II Division I dental malocclusion with upper anterior crowding . Treatment plan: Orthodontic treatment with extraction of upper first premolars to correct the dental malocclusion followed by restorative procedure. Treatment results: Competent lips achieved after orthodontic treatment. A class-II molar relation was maintained .Excellent dental esthetics was seen after direct composite restoration.
ABSTRACT
Aim: The aim of this study was to evaluate the in vitro fracture resistance of teeth restored with bonded ceramic inlay and direct composite resin restoration in comparison to the normal tooth. Materials and Methods: This study evaluated the fracture strength of the teeth restored with bonded ceramic inlay and direct composite resin restoration in comparison to the normal teeth. Thirty intact human maxillary first premolars were assigned to three groups: Group 1 - comprising sound/unprepared teeth (control). Group 2 - comprising of Class-II direct composite resin restored teeth and Group 3 - comprising Class-II ceramic inlay restored teeth. Cavities were prepared with occlusal width of 1/3 intercuspal distance and 2 mm deep pulpally. Group 2 teeth were restored with hybrid composite resin (Z350 3M ESPE, USA) and group 3 teeth were restored with Vitadur Alpha alumina (Ivoclare Vivadent, Liechtenstein, Europe). Ceramic inlay was bonded with adhesive cement (rely X resin cement of 3MESPE, USA). The specimens were subjected to a compressive load until they fractured. Data were analyzed statistically by unpaired Student's t test. Results: The fracture resistant strength, expressed as kilonewton (KN), was group 1 - 1.51 KN, group 2 - 1.25 KN, and group 3 - 1.58 KN. Statistically, group III had highest fracture resistance followed by group I, while group II had the lowest average fracture resistance. Conclusion: The fracture resistant strength of teeth restored with ceramic inlay was comparable to that of the normal intact teeth or slightly higher, while teeth restored with direct composite resin restoration showed less fracture resistant strength than that of the normal teeth.
