This article aims to describe a clinical case of the use of the injectable restorative technique with composite resin in a patient with an esthetic complaint in the anterior teeth. Producing direct restorations in anterior teeth when performed with composite resin demands a long clinical time. Results often depend on the operator's ability to reproduce proper form, function, and esthetics. Lately, the versatility of composite resins has increased. As this material evolved, new techniques were introduced to simplify the restorative process and save time. The restorative technique with injectable fluid composite resin, in addition to delivering faster and with a certain ease, is capable of increasing the predictability of treatment results. However, it is known that flowable resins have lower wear resistance and color stability compared to conventional resins. Thus, a version of this material with a higher filler content in its composition was introduced to the market, to improve wear resistance and gloss retention. Long-term studies evaluating the use of low-viscosity resins are needed. The injectable technique can accurately reproduce the morphology obtained in the wax-up of the case, generating a satisfactory esthetic and functional result. Despite simplifying the fabrication of restorations when compared to the conventional technique, it is still necessary for the operator to have some experience and aptitude. The clinical time for the production of restorations has been considerably reduced. The material showed good flow, shine, and polish in the immediate result. However, the finishing and polishing of the restorations required a longer clinical period than usual and in the short- term follow-up, flaws in the gingival margins and a new finishing and polishing procedure were necessary. Therefore, the technique described in this article can be considered a restorative alternative, but it is still not able to replace the tradit ional method of making previous esthetic restorations.
Este artículo tiene como objetivo describir un caso clínico del uso de la técnica restauradora inyectable con resina compuesta en un paciente con una queja estética en los dientes anteriores. Producir restauraciones directas en dientes anteriores cuando se realizan con resina compuesta demanda un largo tiempo clínico. Los resultados a menudo dependen de la capacidad del operador para reproducir la forma, la función y la estética adecuadas. Últimamente, la versatilidad de las resinas compuestas ha aumentado. A medida que este material evolucionó, se introdujeron nuevas técnicas para simplificar el proceso de restauración y ahorrar tiempo. La técnica restauradora con resina compuesta fluida inyectable, además de una entrega más rápida y segura, es capaz de aumentar la previsibilidad de los resultados del tratamiento. Sin embargo, se sabe que las resinas fluidas tienen menor resistencia al desgaste y estabilidad del color en comparación con las resinas convencionales. Así, se introdujo en el mercado una versión de este material con un mayor contenido de relleno en su composición, con el objetivo de mejorar la resistencia al desgaste y la retención del brillo. Se necesitan estudios a largo plazo que evalúen el uso de resinas de baja viscosidad. La técnica inyectable es capaz de reproducir fielmente la morfología obtenida en el encerado del caso, generando un resultado estético y funcional satisfactorio. A pesar de simplificar la fabricación de restauraciones en comparación con la técnica convencional, todavía es necesario que el operador tenga cierta experiencia y aptitud. El tiempo clínico para la producción de restauraciones se ha reducido considerablemente. El material mostró buena fluidez, brillo y pulido en el resultado inmediato. Sin embargo, el acabado y pulido de las restauraciones requirió de un período de tiempo clínico más largo de lo habitual y en el seguimiento a corto plazo, fueron necesarios defectos en los márgenes gingivales y un nuevo procedimiento de acabado y pulido. Por lo tanto, la técnica descrita en este artículo puede considerarse una alternativa restauradora, pero aún no es capaz de reemplazar el método tradicional de realizar restauraciones estéticas previas.

A estética tem um papel importante na aceitação e autoestima das pessoas e, em virtude disso, os pacientes buscam cada dia mais ter um sorriso harmonioso. As reabilitações estéticas devem envolver um planejamento completo, atrelando função e estética, avaliando tamanho dos dentes, perfil e alturas gengivais, altura do sorriso e corredor bucal. Por conta disso, a odontologia nos permite uma série de abordagens terapêuticas diferentes que chegam a resultados satisfatórios para o paciente. Sendo assim, o presente trabalho tem como objetivo descrever um relato de caso de uma paciente com queixa estética do seu sorriso devido à diferentes tonalidades, formas e tamanhos dos dentes. Após anamnese, exame clínico e radiográfico, o plano de tratamento proposto foi de harmonizações periodontal com aumento de coroa e enxerto gengival, além de coroas em cerâmicas de dissilicato de lítio. Dentro desse contexto, mostra-se que uma abordagem multidisciplinar para reabilitação estética e funcional do sorriso é fundamental, a qual nos proporciona equilíbrio e naturalidade entre estética branca e vermelha no resultado do tratamento reabilitador(AU)
Aesthetics plays an important role in people's acceptance and self-esteem and, as a result, patients increasingly seek to have a harmonious smile. Aesthetic rehabilitations must involve a complete planning, linking function and aesthetics, evaluating tooth size, gingival profile and heights, smile height and buccal corridor. Because of this, dentistry allows us a series of different therapeutic approaches that reach satisfactory results for the patient. Therefore, the present work aims to describe a case report of a patient with an aesthetic complaint of her smile due to different shades, shapes and sizes of teeth. After anamnesis, clinical and radiographic examination, the proposed treatment plan was periodontal harmonization with crown augmentation and gingival graft, in addition to lithium disilicate ceramic crowns. Within this context, it is shown that a multidisciplinary approach to the aesthetic and functional rehabilitation of the smile is fundamental, which provides us with balance and naturalness between white and red aesthetics in the result of the rehabilitation treatment(AU)

Traumatic dental injuries are a worldwide public health problem, among which dental fractures are the most frequent, mainly involving the anterior teeth. The approach of large anterior fractures is a challenge for dental surgeons of any level because, in addition to function, they directly affect the patient's esthetics, requiring a plan that involves different specialties in dentistry. Objective: Report a clinical case of functional and aesthetic rehabilitation of dental fractures in maxillary central incisors involving endodontic treatment, installation of a fiberglass post and direct restoration in composite resin. Case Report: The 17-year-old patient suffered a fracture in the upper central incisors caused by a fall from a bicycle. Due to the late search for treatment, element 21 was diagnosed with pulp necrosis and, therefore, underwent endodontic treatment using the Crown Down Technique and rehabilitation with a Splendor-SAP fiberglass pin. Later, elements 11 and 21 were restored with direct veneers in composite resin using the incremental technique. Conclusion: Rehabilitation with the installation of a fiberglass post associated with the incremental layering technique in composite resin is a good option for aesthetic rehabilitation as it allows the anatomical shape of the tooth with rich details in the layering of dentin and enamel, in addition to maximum preservation of the tooth structure. The results obtained reinforce the aesthetic and functional success with a significant impact on the patient's quality of life(AU)

Introdução: A procura pela estética do sorriso é crescente na Odontologia, pois, muitas vezes um sorriso alinhado e periodonto saudável não são o bastante. A cerâmica odontológica apresenta-se como uma ótima possibilidade restauradora, visto o avanço das técnicas de adesão entre o substrato dentário e as cerâmicas, torna-se mais previsível o resultado com este tipo de reabilitação. Objetivo: O presente artigo tem como objetivo descrever um caso clínico com envolvimento de diversos níveis de desgaste dentário para reabilitação estética com cerâmica de dissilicato de lítio. Relato de caso: Paciente 36 anos, gênero feminino, apresentava insatisfação com seu sorriso devido a forma e a alteração de cor dos seus dentes superiores anteriores e pré-molares. O plano de tratamento consistiu em realizar a troca da coroa metalocerâmica por coroa total cerâmica da unidade 14, coroa total cerâmica nas unidades 11, 21 e 22, facetas cerâmicas nas unidades 15, 13, 12, 23, 24 e 25, osteotomia e gengivoplastia das regiões de 2º prémolar superior esquerdo ao 2º pré-molar superior direito, clareamento dental caseiro da arcada inferior e placa oclusal superior de proteção. O material de escolha para a resolução do caso clínico foi a cerâmica vítrea reforçada à base de dissilicato de lítio, pois, possui um índice de refração de luz semelhante à estrutura dentária, sem interferência significativa da translucidez, além de ser passível de cimentação adesiva por se tratar de uma cerâmica ácido sensível e o tamanho do cristal e a sua disposição favorecem o aumento das propriedades mecânicas da restauração. Conclusão: O plano de tratamento realizado permitiu o restabelecimento da função e estética, com reprodução das características dos dentes naturais e promoção da jovialidade e da harmonia no sorriso(AU)
Introduction:The demand for smile aesthetics is growing in Dentistry, because, often a smile aligned and healthy periodontium are not enough. Dental ceramics, presented as an excellent restorative possibility, since the advancement of adhesion techniques between the dental substrate and the ceramics, becomes more predictable the result with this type of rehabilitation. Objective: This article aims to describe a clinical case involving several levels of dental wear for aesthetic rehabilitation with ceramics. Case Report: A 36-year-old female patient presented dissatisfaction with her smile due to the shape and color alteration of her anterior and premolar upper teeth. The treatment plan consisted of exchanging the metal-ceramic crown for the total ceramic crown of unit 14, total ceramic crown in units 11, 21 and 22, ceramic veneers in units 15, 13, 12, 23, 24 and 25, osteotomy and gingivoplasty of the regions from 2nd left upper premolar to 2nd right upper premolar, home tooth whitening of the lower arch and upper occlusal plate of protection. The material of choice for the resolution of the clinical case was the glass ceramic reinforced on the basis of lithium disilicate because it has a refractive index of light similar to the dental structure, without significant interference of translucency, besides being liable to adhesive cementation because it is a sensitive acid ceramic and the size of the crystal and its disposition favor the increase of the mechanical properties of the restoration. Conclusion: The treatment plan performed allowed the restoration of function and aesthetics, with reproduction of the characteristics of natural teeth and promotion of joviality and harmony in the smile(AU)

Aims: To verify the efficacy of Er,Cr:YSGG laser for debonding of lithium disilicate (LD) reinforced glass ceramic veneers of different thicknesses. Methods: Forty bovine teeth were prepared and randomly divided into four groups (n=10/group) according to the ceramic disc thickness: C0.5 (Control group) and L0.5 (Laser irradiated group) in which LD discs had a thickness of 0.5mm and 5mm diameter; C1 and L1 in which LD discs had a thickness of 1mm and 5mm diameter. The lithium disilcate discs (IPS E.max®, shade HTA2) were fabricated following the manufacturer's recommendations and cemented to the prepared tooth surface. The Er,Cr:YSGG laser was applied to the laser groups at 2.5W and 25Hz for 60seconds. Universal testing machine was used to evaluate the shear bond strength for all samples at a cross head speed of 1mm/min in an inciso-gingival direction parallel to the sample surface. After debonding, the samples were examined under stereoscope to evaluate the mode of failure according to the adhesive remnant index (ARI). Results: Laser irradiation significantly diminishes the shear bond strength from 10.868 MPa to 3.778 MPa for C0.5 and L0.5 groups respectively (p=0.00) and from 14.711 MPa to 4.992 MPa for C1 and L1 groups respectively (p=0.00). The shear bond strength required for debonding increased with increasing thickness of discs, but without significant difference (p=0.110). Higher ARI scores were seen in the laser groups (more cement remaining adhered to the tooth) when compared to the control groups. Conclusions: The Er,Cr:YSGG laser could be an effective and useful tool in debonding of lithium disilicate ceramic veneers as it decreases the shear bond strength required for veneer debonding

Abstract To evaluate stress distribution when applying vertical and tangential forces to 1mm thick occlusal veneers with different finish lines preparations, using the finite element method. One extracted third molar was prepared for occlusal veneers, firstly without any bevel. It was scanned in order to design two groups of lithium disilicate (G1A, G2A) and composite resin (G1B, G2B) occlusal veneers. Then, the third molar preparation was modified, beveling the finish line and it was subsequently scanned again to design the occlusal veneer groups with bevel (LD: G3A, G4A and CR: G3B, G4B). The four groups were subjected to different forces (400 N vertical and 900 N tangential). At 400 N, the non-beveled veneers showed slightly higher Von Mises stress values (G1A: 783 MPa and G1B 736.5 MPa) than the beveled veneers (G3A: 685.7 MPa and G3B: 675.8 MPa). However, when 900 N tangential forces were applied, the beveled occlusal veneers showed higher Von Mises stress values (G4A: 4297 MPa and G4B: 4133 MPa) than the non-beveled occlusal veneers (G2A: 2581.1 MPa and G2B: 3519.1 MPa). Furthermore, it was observed that the tissue under the occlusal veneers with bevel showed higher Von Mises stress values than the models without any bevel. Beveled and non-beveled occlusal veneers of lithium disilicate and composite resin presented similar stress distribution values when vertical forces of 400 N were applied; whereas with tangential forces of 900 N applied near to the finish line, the beveled groups presented notably higher stress values than the non-beveled groups. However, both finish line preparations presented adequate values for possible clinical performance.
Resumen Evaluar la distribución de estrés al aplicar fuerzas verticales y tangenciales en carillas oclusales de 1mm de espesor con diferentes líneas de terminación marginal por el método de elementos finitos. Se preparó un tercer molar extraído para carilla oclusal, primero sin bisel. Se escaneó para diseñar dos grupos de carillas oclusales de disilicato de litio (G1A, G2A) y resina compuesta (G1B, G2B). Después, esta preparación molar fue modificada, biselando la línea de terminación y escaneándola nuevamente para diseñar los grupos de carillas oclusales con bisel (DL: G3A, G4A and RC: G3B, G4B). Los 4 grupos fueron sometidos a fuerzas diferentes (400 N vertical y 900 N tangencial). Con 400 N, las carillas sin bisel presentaron ligera mayor tensión de Von Mises (G1A: 783 MPa y G1B 736.5 MPa) que las carillas con bisel (G3A: 685.7 MPa y G3B: 675.8 MPa). De distinta forma, al aplicar fuerzas tangenciales de 900 N, las carillas oclusales con bisel presentaron mayor tensión de Von Mises (G4A: 4297 MPa y G4B: 4133 MPa) que las carillas oclusales sin bisel (G2A: 2581.1 MPa y G2B: 3519.1 MPa). Además, se observó que los tejidos subyacentes a las carillas oclusales con bisel, presentaron mayor tensión de Von Mises, frente a los modelos sin bisel. Las carillas oclusales con y sin bisel de disilicato de litio y resina compuesta presentaron una distribución de estrés similar con fuerzas verticales de 400 N, por otro lado, con fuerzas tangenciales de 900 N, los grupos con bisel presentaron notablemente mayor tensión que los grupos sin bisel. Sin embargo, ambos diseños de terminación marginal presentaron valores adecuados para un posible desempeño clínico.

OBJECTIVE@#To analyze the marginal roughness and marginal fitness of chairside computer-aided design and computer-aided manufacturing (CAD/CAM) laminate veneers with different materials and thicknesses, and to provide a reference for the clinical application of laminate veneers.@*METHODS@#The butt-to-butt type laminate veneers were prepared on resin typodonts, the preparations were scanned, and the laminate veneers were manufactured by chairside CAD/CAM equipment. The laminate veneers were divided into four groups (n=9) according to the materials (glass-matrix ceramics and resin-matrix ceramics) and thickness (0.3 mm and 0.5 mm) of the veneers, with a total of 36. The marginal topo-graphies of each laminate veneer were digitally recorded by stereomicroscope, and the marginal rough-nesses of the laminate veneers were determined by ImageJ software. The marginal fitness of the laminate veneers was measured by a fit checker and digital scanning and measuring method. At the same time, the mechanical properties of glass-matrix ceramic and resin-matrix ceramic bars (n=20) were tested by a universal testing device.@*RESULTS@#The marginal roughness of 0.3 mm and 0.5 mm glass-matrix ceramic laminate veneers was (24.48±5.55) μm and (19.06±5.75) μm, respectively, with a statistically significant difference (P < 0.001). The marginal roughness of 0.3 mm and 0.5 mm resin-matrix ceramic laminate veneers was (6.13±1.27) μm and (6.84±2.19) μm, respectively, without a statistically significant difference (P>0.05). The marginal roughness of the glass-matrix ceramic laminate veneers was higher than that of the resin-matrix ceramic laminate veneers with a statistically significant difference (P < 0.001). The marginal fitness of 0.3 mm and 0.5 mm glass-matrix ceramic laminate veneers were (66.30±26.71) μm and (85.48±30.44) μm, respectively. The marginal fitness of 0.3 mm and 0.5 mm resin-matrix ceramic laminate veneers were (56.42±19.27) μm and (58.36±8.33) μm, respectively. There was no statistically significant difference among the 4 groups (P>0.05). For glass-matrix ceramics, the flexural strength was (327.40±54.25) MPa, the flexural modulus was (44.40±4.39) GPa, and the modulus of resilience was (1.24±0.37) MPa. For resin-matrix ceramics, the flexural strength was (173.71±16.61) MPa, the flexural modulus was (11.88±0.51) GPa, and the modulus of resilience was (1.29±0.27) MPa. The flexural strength and modulus of glass-matrix ceramics were significantly higher than those of resin-matrix ceramics (P < 0.001), but there was no statistically significant difference in the modulus of resilience between the two materials (P>0.05).@*CONCLUSION@#The marginal roughness of CAD/CAM glass-matrix ceramic laminate veneers is greater than that of resin-matrix ceramic laminate veneers, but there was no statistically significant difference in marginal fitness among them. Increasing the thickness can reduce the marginal roughness of glass-matrix ceramic laminate veneers, but has no effect on the marginal roughness of resin-matrix ceramic laminate veneers.

Abstract In the RLT (Rapid Layer Technology), veneering ceramic and framework are fabricated by computer-aided design/computer-aided manufacturing (CAD/CAM) and then cemented to obtain the restoration. This study aimed to evaluate the effect of the thickness of veneering ceramic manufactured by the RLT technique on the fracture resistance (FR) of bilayer crowns with zirconia frameworks. Twenty zirconia frameworks and twenty feldspathic posterior crowns with two different veneering ceramic occlusal thicknesses (1mm=TF1; 2mm=TF2) were manufactured using CAD/CAM system. The specimens were luted to an epoxy resin abutment with resin cement and mechanically cycled (200N and 4.5×105 Pa, 37°C, 2×106 cycles, 3Hz). The FR test was performed (10kN, 0.5mm/min), and the specimens were analyzed in a stereomicroscope. For the stress analysis (finite element analysis, FEA), a 10kN load was equal to the in vitro test, and the principal stress was evaluated. The FR data were analyzed by Student's t-test and Weibull's analysis. The thickness influenced the FR of bilayer crowns. The FR was higher in the TF2 than in the TF1 group. The TF2 group presented the highest characteristic strength compared to the group TF1. The predominant type of failure was delamination. The FEA showed higher stress concentrations below the loading application point at the veneering cement interface in the 1-mm-thick model. The bilayer crowns manufactured using the approach of 2mm of veneering ceramic promoted higher FR compared to the group with 1mm veneering ceramic. Also, the FEA showed that the veneer ceramic thickness has an effect on stress distribution in zirconia-based bilayer crowns.
Resumo Na RLT (Rapid Layer Technology), a cerâmica de cobertura e infraestrutura são fabricados pelo Computer-Aided Design / Computer-Aided Manufacturing (CAD / CAM) e cimentados para obter a restauração. Este estudo teve como objetivo avaliar o efeito da espessura da cerâmica de cobertura fabricada pela técnica RLT na resistência à fratura (RF) de coroas bilaminadas com infraestrutura de zircônia. Vinte infraestruturas de zircônia e vinte coroas posteriores feldspáticas com duas espessuras oclusais da cerâmica de cobertura (1mm = TF1; 2mm = TF2) foram fabricadas usando o sistema CAD / CAM. Os espécimes foram cimentados em preparos de resina epóxi com cimento resinoso dual e ciclados mecanicamente (200N e 4,5×105 Pa, 37° C, 2×106 ciclos, 3Hz). O teste de RF foi realizado (10kN, 0,5mm / min) e, posteriormente, os espécimes foram analisados em estereomicroscópio. Para a análise de tensão (análise de elementos finitos, FEA), uma carga de 10kN foi aplicada igual ao teste in vitro, e a tensão principal foi avaliada. Os dados de RF foram analisados pelo teste t de Student e análise de Weibull. A espessura mostrou forte influência na RF das coroas bilaminadas. A RF foi maior em TF2 do que no grupo TF1. O grupo TF2 apresentou a maior resistência característica em relação ao grupo TF1. O tipo de falha predominante foi a delaminação. O FEA mostrou maiores concentrações de tensões abaixo do ponto de aplicação da carga, na interface cimento e cerâmica de cobertura no modelo de coroa de 1 mm de espessura. As coroas de bilaminadas confeccionadas com 2 mm de cerâmica de cobertura promoveram maior RF em comparação ao grupo com cerâmica de cobertura de 1 mm. Além disso, a FEA mostrou que a espessura da cerâmica de cobertura tem um efeito na distribuição de tensões em coroas bilaminadas à base de zircônia.

RESUMEN De acuerdo al modelo patológico multifactorial, la morfología dental ha sido asociada como uno de los factores etiológicos de la caries al favorecer el acumulo de restos alimenticios y la retención de biopelícula. Uno de los rasgos morfológicos dentales más frecuentes de la población colombiana es el punto P del protostílido, el cual se constituye en una fosa que se expresa en el surco de desarrollo vestibulomesial de los molares inferiores, región que le sigue a la superficie oclusal como uno de los sitios en donde se desarrollan con más frecuencia lesiones cariosas. Sin embargo, el desconocimiento de este rasgo morfológico por la mayoría de los odontólogos hace que el sistema morfológico del protostílido sea mal diagnosticado, lo que conlleva en muchos casos al sobretratamiento de dicha fosa con terapéuticas invasivas, las cuales, podrían ser evitadas con un conocimiento adecuado de la morfología dental y con un manejo preventivo o con técnicas no invasivas. Por tanto, el objetivo de esta revisión de tema es reconocer la expresión del punto P del protostílido y realizar una aproximación a las implicaciones clínicas del mismo y las posibilidades diagnósticas y terapéuticas conservadores que ofrece la odontología para controlar el acumulo de restos alimenticios y la retención de biopelícula.
ABSTRACT According to the multifactorial pathological model, dental morphology has been associated as one of the etiological factors of caries by favoring the accumulation of food remains and biofilm retention. One of the most frequent of non-metric dental traits of the Colombian population is the P point of the protostylid, which is constituted in a fossa that is expressed in the bucomesial development groove of the lower molars, a region that follows the occlusal surface as one of sites where carious lesions develop more frequently. However, the lack of knowledge of this morphological feature by most dentists makes the morphological system of the protostylid misdiagnosed, which in many cases leads to the overtreatment of this pit with invasive therapies, which could be avoided with a knowledge adequate dental morphology and with a preventive management or non-invasive techniques. Therefore, the aim of this review of the subject is to reconcile the expression of the P point of the protostylid and to make an approximation to the clinical implications of the same and the conservative diagnostic and therapeutic possibilities offered by dentistry to control the accumulation of food rests and retention of dental biofilm.
