“…In the absence of ferrule, it was stated that poor clinical outcome is to be expected [39]. A recent systematic review presented a trend confirming that statement (88% restoration survival with ferrule vs 78% without ferrule), but without statistically significant differences [42].…”

Aim Resin composite (RC) are commonly used under full crowns. However, independent information is lacking to guide practitioners regarding core RC material selection. This study aimed at comparing the flexural properties of a large selection of commercially-available core build-up RCs (CBU-RC), either light-, self- or dual-cure, to conventional light-cure RCs. Methods RCs were injected into a 25 × 2×2mm Teflon mold, and either light-cured during 20 s (materials with claimed light-cure characteristics) or covered by aluminum during 10 min (dual- and self-cure CBU-RCs). They were subjected after a one-week water storage at 37.5 °C to three-point bending, and Flexural modulus ( E flex ) and Flexural Strength ( σ f ) were calculated ( n = 20). Thermogravimetric analysis ( n = 3) was performed to determine inorganic filler content (%). Results For dual-cure CBU-RCs, both RC ( p < .0001) and light-curing ( p = .0007) had a significant influence on E flex , while only RC was significant for σ f ( p < .0001). Between all conventional RCs and CBU-RCs, significant differences were observed ( p < .0001), both regarding E flex and σ f , with values ranging from 3.9 to 15.5 GPa and from 76 to 130.3 MPa, respectively. Higher E flex values were observed for light-cure RCs than for self- and dual-cure ones, while no clear trend was noticed regarding σ f . Good linear correlation was found between inorganic filler content and E flex ( R 2 =0.85, p < .0001), but not with σ f ( R 2 =0.08, p = .1609). Conclusion This work demonstrated a positive influence of light-curing on dual-cure CBU-RC’s E flex . It also highlighted large differences in flexural properties (especially E flex ) among the investigated materials, questioning the use of some CBU-RCs as dentin replacement in case of large tissue loss.

“…Su presencia confiere un efecto protector durante la inserción de un poste, pues otorga resistencia a las fuerzas funcionales, las fuerzas laterales y al efecto de cuña de los postes metálicos. Asimismo, impide la exposición directa del cemento y consecuentemente, una reducción de fallas como desprendimientos de la corona o la posibilidad de microfiltraciones (Batista et al, 2020).…”

Section: Importancia Del Efecto Férula En La Restauración De Dteunclassified

“…Antiguamente se empleaban postes metálicos (Figura 3A), hoy en día se encuentran en desuso debido a numerosas desventajas, entre ellas: su alto módulo de elasticidad (220 GPa) (Sorrentino et al, 2016), la posible corrosión de las aleaciones metálicas y su combinación con diversos materiales con los que las coronas o incrustaciones están elaboradas, mismos que contribuyen a la fractura de la pieza dentaria; además, por su opacidad, interfieren en el paso de la luz, disminuyendo la transparencia de la encía, visualizándose una zona oscura a nivel del festón gingival y dando un aspecto poco o nada estético (Aguero et al, 2017). La alternativa más aceptada es el uso de postes de fibra de vidrio (22-57 GPa) (Figura 3B) que han demostrado mayor biocompatibilidad por su módulo de elasticidad similar al de la dentina (42 GPa) (Sorrentino et al, 2016), lo cual produce una distribución de estrés más uniforme y reduce considerablemente el riesgo a la fractura; de igual manera, tiene ventajas a nivel estético y en el tiempo de trabajo (Batista et al, 2020;Marchionatti et al, 2017;Sorrentino et al, 2016).…”

La restauración definitiva de un diente tratado endodónticamente (DTE) es fundamental para prevenir una posible reinfección periapical, lo que determina su pronóstico a corto y largo plazo. Este trabajo tiene como objetivo determinar la tasa de sobrevida y qué tipo de restauración está indicada en dientes posteriores tratados endodónticamente de acuerdo a la pérdida de estructura dentaria. Para ello, se realizó una búsqueda en las bases digitales Cochrane, Scopus y Pubmed acorde a criterios de inclusión y exclusión; y una búsqueda manual en Google Scholar. Como resultado se obtuvieron 34 artículos para la lectura de texto completo, se tomó dos clasificaciones que permitieron a los revisores unificar criterios y proponer una nueva clasificación que facilitará a los lectores elegir la forma de restauración ideal en los dientes posteriores. Para aquellas piezas dentarias con perdida mínima de estructura coronaria, el tratamiento de elección son restauraciones de composite (91.9%-100% de éxito); en piezas con pérdida moderada de tejido dentario, se recomienda la utilización de restauraciones indirectas de cobertura parcial o total (92.4%-98.9%) con el uso o no de un poste de fibra de vidrio y, por último, en piezas con gran pérdida de remanente se optaría por técnicas alternativas que permitan preservar tejido dentario. Es preciso conocer las opciones existentes al momento de escoger un tipo de restauración conforme a los requerimientos de la pieza dentaria, considerando ser lo más conservador posible para no debilitar aún más su estructura.

“…Fracture of tooth due to trauma or biting on hard food is a common clinical scenario we face often. This can happen to a vital tooth or a tooth that had undergone an endodontic treatment as tooth become brittle after endodontic treatment (1,2).Endodontically treated teeth that show loss of coronal structure and have undergone comprehensive restorations are typically restored with post and core accompanied by restoration of the prosthetic crown (1,(3)(4)(5)(6). The post has two fold functions; It provides intracanal retention of the core and crown restoration and distribution of functional loading over a large area of the remaining tooth structure to achieve favorable stress distribution in endodontically treated tooth (1,3,7).…”

Purpose: This clinical case discusses the step-by-step implementation of a core and a post system that uses a single resin composite material for cementation of a glass fibre post and core build up of a fracture endodontically treated maxillary left first premolar with gingivectomy as a crown lengthening procedure. Clinical considerations: Several materials and methods has been discussed in the literatures regarding restoration of endodontically treated teeth with minimal tooth structure left which require fibre post and core build up. Gingivectomy as a crown lengthening is also a common procedure that facilitates restorative dentistry. This case presents a restoration of a tooth with a short clinical crown by gingivectomy and post core build up by glass fibre post with a mono-block technique or core-and-post technique with dual cure composite resin as a luting and core build up material. Conclusion:Post and core is needed to restored tooth with little tooth structure remaining.Glass fibre post are prefabricated posts which makes it easy to manipulate and reduces chairs side time among other advantages. Use of single material system for post-and-core reduces the steps of manipulation and chair side time compared to conventional techniques. Clinical significance: More measures are required when different materials are used for post-cementation and core build-up, increasing the chair time and the number of interfaces between the materials. However, these shortcomings can be overcome by the mono-block technique where only one material is used for both cementation and core build up. Update Dent. Coll. j: 2021; 11(2): 38-42
