Cemented and screw-retained implant-supported single-tooth restorations in the molar mandibular region: A retrospective comparison study after an obs…
2015
Objectives: The aim of this study was to evaluate the survival and compare the appearance of different mechanical and biological complications, in screw-retained and cemented-retained single-tooth implant-supported restorations localized in the molar mandibular region, over a period of 1 to 4 years. Material and Methods: A retrospective study was carried out with a total of eighty implant-supported restorations, which were placed in eighty patients for prosthetic rehabilitation of a mandibular molar. Forty patients were rehabilitated with a cemented-retained restoration and the other forty with a screw-retained restoration. The presence of the following complications was recorded for both t…
Novel Digital Technique to Quantify the Area and Volume of Cement Remaining and Enamel Removed after Fixed Multibracket Appliance Therapy Debonding: …
2020
The aim of this study was to construct a novel, repeatable, reproducible, and accurate measurement protocol for the area and volume of the remaining cement after removal of fixed multibracket appliances, the area and volume of remaining cement after cement removal, the area and volume of enamel removed after cement removal, and the volume of cement used to adhere fixed multibracket appliances. A total of 30 brackets were cemented and removed with over 30 extracted teeth embedded into three experimental models of epoxy resin. The models were scanned before and after bracket placement, bracket debonding, and polishing the remaining cement. The brackets were submitted to micro-computed tomogra…

Clinical justification of dental radiology in adult patients: A review of the literature
2007
Although the radiological doses used by dentists are low individually, patients are often exposured to many repeat dental radiographic examinations. The ‘routine’ use of dental radiography, such as screening of all patients using dental panoramic radiography (DPRs) or a random decision to take a dental radiograph, will inevitable lead to unnecessary patient exposure. The use of Radiographic Referral Criteria has now become a legal requirement for all practitioners following the adoption of European Legislation. All exposures to x-rays should be clinically justified and each exposure should be expected to give the patient a positive net benefit. Recently the European Commission has published…
Estudio clínico del sistema Locator® en pacientes portadores de sobredentaduras sobre implantes
2013
1. Introducción. Los pacientes edéntulos son un grupo poblacional considerable y con necesidades terapéuticas. Las sobredentaduras retenidas sobre implantes son una adecuada alternativa, sobre todo a nivel mandibular, mejorando el comportamiento de las tradicionales prótesis completas removibles. Además las sobredentaduras suponen una mejora en la calidad de vida oral de los pacientes desdentados. 2. Objetivos. Los objetivos planteados en el presente trabajo fueron los siguientes: 1. Analizar el comportamiento del sistema Locator® en pacientes portadores de sobredentaduras mandibulares retenidas mediante dos implantes, para lo cual estudiaremos los siguientes parámetros: a) Éxito de implant…
Injertos óseos en bloque intraorales tipo onlay: estudio de los tejidos duros y blandos periimplantarios
2016
Los injertos óseos en bloque intraorales tipo onlay son una opción terapéutica para incrementar tanto la anchura como la altura del proceso alveolar para la posterior colocación de los implantes dentales. La colocación simultánea del implante con el injerto óseo permitiría acortar el tiempo de tratamiento y evitar un segunda cirugía, sin embargo aunque se ha descrito ampliamente en el aumento vertical, son escasos los estudios en el tratamiento del aumento horizontal. Por otro lado, diversos procedimientos se han utilizado para la atrofia vertical de los sectores posteriores de la mandíbula atrófica, sin embargo las complicaciones relacionadas con los procedimientos de aumento ha hecho que …
Influence of Oral Health Care Systems on Future Career Environment of Dental Students in Europe
2021
Oral healthcare is organized subsidiarily and independently by nation states in Europe and also within the EU and consequently, major differences between the nation states and the various oral healthcare systems in Europe are present. The socialization in the respective catchment area can have an impact on the job choice and the perception of employment opportunities of different professional groups. Therefore, the purpose of this survey was to elucidate the influence of different oral healthcare systems on students living or studying in the respective catchment area. A questionnaire (in English, French, German, Italian, and Spanish) with 18 different components was administered. Data on ge…
Isolated lip dermatitis (atopic cheilitis), successfully treated with topical tacrolimus 0.03%
2020
Background Exfoliative and erosive cheilitis, may be a source of speech and chewing discomfort, but may also be an aesthetic issue for the patients affected. Such a clinical presentation may implicate a variety of inflammatory conditions, including atopic (eczematous) cheilitis. Topical and systemic agents, e.g. corticosteroids, have been used to treat inflammatory lip conditions. Topical tacrolimus has also been used in some inflammatory lip conditions. Material and Methods We performed a retrospective clinical analysis of atopic cheilitis patients. Results Between 2015 and 2020, we addressed 7 (seven) patients with atopic dermatitis affecting only lips and were diagnosed as atopic-eczemat…
Regeneración de cartílago mediante el uso de células madre de pulpa dental humanas (hDPSCs)
2020
El tejido cartilaginoso es un tejido fundamental, puesto que proporciona sostén a nuestro organismo. Cuando el cartílago articular se lesiona experimenta una regeneración compleja y limitada. Por ello es importante buscar alternativas y ampliar las soluciones que se están utilizando actualmente para tratar enfermedades en las que se produce la alteración del cartílago articular, como la osteoartritis. Con la base en esta idea, recientemente la ingeniería tisular ha desarrollado distintas herramientas para tratar de regenerar el cartílago cuando la regeneración por otras vías no es posible. Dentro de las estrategias que existen, se ha potenciado el uso de hidrogeles combinados con condrocito…
Estudio in vitro de la respuesta osteoblástica sobre discos de titanio en función de su rugosidad y la aplicación tópica de melatonina
2017
La implantología dental es una rama de la odontología que tiene como objetivo reemplazar las funciones masticatorias, fonéticas y estéticas de los dientes perdidos gracias a la colocación quirúrgica de uno o varios implantes dentales en el hueso maxilar o mandibular, y su posterior rehabilitación protésica implantorretenida. La implantología dental está en constante evolución, respondiendo a la demanda de la restauración estética y funcional que exigen los pacientes con la mayor brevedad posible. Según Branemark “El éxito clínico de los implantes dentales está basado en la oseointegración”, es decir, “la conexión directa estructural y funcional entre hueso vivo, ordenado y la superficie del…
