    Evaluación de la microfiltración en restauraciones indirectas de cerómero cementadas con: agente adhesivo dual, autoadhesivo y resina restaurativa precalentada
    (Universidad de Cuenca, 2018) Bucheli, María del Carmen; Mena Córdova, Nancy; Abad Coronel, Cristian Gustavo; Sandoval Vernimmen, Fernando Raúl
    The purpose of this study was to evaluate the microfiltration in indirect ceromer restorations Ceramage A1 Body (Shofu), cemented with a dual adhesive agent RelyX ARC (3M ESPE); with a RelyX U200 self-adhesive (3M ESPE) and a Filtek Supreme Z350 pre-heated restorative resin (3M ESPE) for 10 minutes at 55 ° C. The sample consisted of 60 third molars, in which mesio-occluso-distal MOD cavities with 3 mm depth and width (inlays) were performed. Impression was made with addition silicone and the restorations were made. The samples were divided into groups of 20; the first group was cemented with dual adhesive agent, the second group with self-adhesive and the third with pre-heated restorative resin, following the manufacturer's instructions. All samples were photocured with Optilux 501 halogen light (SDS Kerr) at 1020 mw / cm2, for 40 sec. each surface , then were subjected to 10,000 cycles Introducción Las restauraciones indirectas en el sector posterior se han convertido en la mejor opción cuando la destrucción coronal es amplia y compromete una cara proximal, ya que las restauraciones directas tienen mayor índice de contracción, formando espacios entre la interfase de la estructura dental y la resina, dando paso a la microfiltración, siendo éste un fenómeno dinámico que provoca pigmentación marginal, caries secundaria, sensibilidad post operatoria, lesiones pulpares, y fallas en la adhesión (1) (2) (3). Es así que el uso de restauraciones indirectas se popularizó a partir de 1980, ya que presentan mayor control en su polimerización, por lo tanto mejor contorno anatómico y proximal, estética y cualidades de pulido (4) (5). Su uso está indicado cuando no hay paredes proximales, cuando la altura del piso a cúspide es de 1.5-3 mm o cuando la medida entre cúspides es la mitad de la totalidad de las misma. (6) Uno de los varios materiales que se utilizan en una restauración indirecta es el cerómero, por su biocompatibilidad, sin embargo la técnica de cementación se vuelve un protocolo susceptible. En el mercado existen diferentes tipos de cemento a base de resina que han probado tener una alta resistencia en restauraciones de composite; ya que se caracterizan por ser resilentes, tienden a deformarse y a absorber fuerzas de tensión. (7) (8) of thermocycling and submerged in 2% basic fuchsin for 24 hours at room temperature. Macro- photographies were taken of the MOD surfaces and marginal microfiltration was evaluated in ranges from 0 to 4 between the inlays and the dental structure; 0 being the one that does not present any pigmentation and 4 presence of cracks. It is concluded that the samples that have lower marginal microfiltration are cemented with preheated restorative resin, followed by cemented with the dual adhesive agent and finally those cemented with self adhesive. In addition, the surface with the lowest microfiltration was the occlusal, followed by the mesial and finally the distal surface in all cases

    Rehabilitación del maxilar superior con atrofia alveolar maxilar severa: presentación de caso clínico
    (Universidad de Cuenca, 2010-07) Abad Coronel, Cristian Gustavo; Cabrera Maldonado, Leonardo
    The prosthetic rehabilitation, in patients with severe maxillary atrophy in our environment has been limited to use of removable dentures in certain cases, and surgícal treatments aimed at increasing the upper jaw bone, in order to achieve a suitable ground for conventíonal implant fixation. This is a case in which two zygomatic implants were used, one on each side, and three conventional implants in the maxillary anterior región to build a hybrid prosthesis; which has been under observation for four years. The clinical significance ís of this article is to establish that there is an additional option to rehabilítate patients with severe maxillary atrophy without performing surgeñes increased bone tissue for the subsequent fixing of conventional implants, which the patient observes reduced recovery time and treatment sessions without neglecting the implications of a complex procedure and requires properly trained and experienced staff.

    Restauraciones indirectas mediante la utilización del sistema CAD CAM CEREC.
    (Universidad de Cuenca, 2009-07) Abad Coronel, Cristian Gustavo
    Objective: The aim of thís paper was to present, describe, and analyze the CAD CAM CEREC System (Síroña Dental Systems GmbH, Bensheim, Germany) for indirect restorations, through literature rewiew. Material and Methods: The system of the Pub Med National Library Service for the United States of America, was used through its electronic publications. Conclusion: According to the reviewed publications from 1984 through 2008, the system CAD CAM Cerec has clinical relevance for achieving esthetic, durable, metal free and biocompatible indirect restorations, in one session or in a short period of time up to two days in the same dental office.

    Tratamiento de amelogénesis imperfecta mediante un flujo de trabajo digital: reporte de un caso clínico
    (Universidad de Cuenca, 2021) Buele Lanchi, Cristopher Oswaldo; Tinoco Arévalo, Juan Pablo; Bernal Álverez, Andrea Fernanda; Juela Corte, Nicole Adriana; Abad Coronel, Cristian Gustavo
    The objective of this article was to present a clinical case of amelogenesis imperfecta (AI) with secondary caries lesion in three first molars, resolved by applying a digital workflow. Methodology: A case of AI was diagnosed and restored using a digital impression and a restoration performed through computer-aided design and machining. Conclusion: The application of a digital workflow is feasible to restore a clinical case with AI in a single session
