Comportamiento periodontal de restauraciones de recubrimiento completo sobre preparaciones dentarias sin línea de terminación: Estudio clínico prospe…

2020

La estabilidad de los tejidos gingivales es uno de los retos para la rehabilitación estética con prótesis fija. La técnica de preparación BOPT es un protocolo en el cual se elimina la emergencia de la corona anatómica dental y la línea de terminación preexistente. La experiencia clínica mediante esta técnica, ha demostrado producir un aumento del grosor gingival y generar una mejor estabilidad de los tejidos blandos a medio y largo plazo. Objetivo: Evaluar el comportamiento clínico y biológico de las restauraciones de recubrimiento total en dientes preparados sin línea de terminación durante un seguimiento de 6 años. Material y Métodos: Este estudio prospectivo incluyó 149 dientes tratados …

Influence of Biologically Oriented Preparation Technique on Peri-Implant Tissues; Prospective Randomized Clinical Trial with Three-Year Follow-Up. Pa…

2019

Purpose: The objective of this prospective randomized clinical trial (RCT) was to analyze and compare the clinical behavior of three types of prosthesis supported by single implants in the posterior region after three years of functional loading. Materials and methods: Seventy-five implants were divided into three groups according to the type of prosthetic restoration: screw-retained crown (group GS); cemented crown without finishing line (biologically oriented preparation technique) (group GBOPT); and conventional cemented crown with finishing line (group GCC). After three years in function, clinical parameters (presence of keratinized mucosa, probing depths, bleeding on probing, and radio…

Analogical and Digital Workflow in the Design and Preparation of the Emergence Profile of Biologically Oriented Preparation Technique (BOPT) Crowns o…

2019

: The Biologically Oriented Preparation Technique (BOPT), developed by Ignacio Loi and published in 2008, is a consolidated concept in the modeling and preservation of pericoronal soft tissues. The present study describes the analogical and digital methods allowing adequate design and preparation of the emergence profile of BOPT crowns in the working model, with a view to comparing the workflow and advantages of each method. At present, not all the digital procedures have been fully optimized to completely replace the traditional analogical methods. Nevertheless, it is only a matter of time until dental digitalization technology totally replaces the analogical clinical methods. The digital …

Keys to world Charipinae (Hymenoptera, Cynipoidea, Figitidae)

2019

Eight genera of Charipinae are defined, keyed out, and illustrated. Keys for all charipine species within each valid genus, includingAlloxysta,Apocharips,Dilyta,Phaenoglyphis, andThoreauana, are presented, except forDilapothor,Lobopterocharips, andLytoxysta, which are monotypic. Figures are provided to show the diagnostic morphological features as used in the keys.

The clinical behavior of each restoration type was analyzed after 3 years functional loading by analyzing radiographic peri-implant b…

Controlled polyhedral sweeping processes: existence, stability, and optimality conditions

2021

This paper is mainly devoted to the study of controlled sweeping processes with polyhedral moving sets in Hilbert spaces. Based on a detailed analysis of truncated Hausdorff distances between moving polyhedra, we derive new existence and uniqueness theorems for sweeping trajectories corresponding to various classes of control functions acting in moving sets. Then we establish quantitative stability results, which provide efficient estimates on the sweeping trajectory dependence on controls and initial values. Our final topic, accomplished in finite-dimensional state spaces, is deriving new necessary optimality and suboptimality conditions for sweeping control systems with endpoint constrain…

Periodontal Behavior and Patient Satisfaction of Anterior Teeth Restored with Single Zirconia Crowns Using a Biologically Oriented Preparation Techni…

2021

bjectives. The aim of this study was to analyze the behavior of the periodontal tissues around teeth in the anterior region when restored with zirconia single crowns, using a biologically oriented preparation technique (BOPT), over a 6-year follow-up. Methods. The study investigated tooth-supported single crowns in the anterior region that were fabricated with a zirconia core and feldspathic ceramic covering, in 34 patients. Follow-up analysis took place annually for 6 years, assessing periodontal responses by evaluating the following variables: plaque index (PI)

Potential of using data assimilation to support forest planning

2017

Uncertainty in forest information typically results in economic and ecological losses as a consequence of suboptimal management decisions. Several techniques have been proposed to handle such uncertainties. However, these techniques are often complex and costly. Data assimilation (DA) has recently been advocated as a tool that may reduce the uncertainty, thereby improving the quality of forest planning results. It offers an opportunity to make use of all new sources of information in a systematic way and thus provides more accurate and up-to-date information to forest planning. In this study, we refer to literature on handling uncertainties in forest planning, as well as related literature …

THE OPTIMIZATION OF INTERFERON FOR MS STUDY: 375 MICROG INTERFERON BETA-1B IN SUBOPTIMAL RESPONDERS.

2008

We aimed to evaluate the safety and MRI efficacy of interferon beta-1b (IFNbeta-1b) 375 microg (subcutaneously [sc] every other day [eod]) in relapsing-remitting multiple sclerosis (RRMS) patients with a suboptimal response to IFNbeta-1b 250 microg, i.e., with MRI activity or relapses. The OPTimization of Interferon for MS (OPTIMS) study was a prospective multicenter randomized phase 2 trial comprising a 6-month run-in phase (to identify suboptimal responders) and a 6-month randomized phase of open-label clinical and blinded MRI follow-up. During run-in all patients were treated with IFNbeta-1b 250 microg sc eod; during the study phase suboptimal treatment responders were randomized either …
