Development of patient-based questionnaire about a esthetic and functional differences between overdenture simplant-supported and overdentures tooth-supported. Study of 43 patients with a followup of1 year
Full text linkDevelopment of patient-based questionnaire about aesthetic and functional differences between overdenturesimplant-supported and overdentures tooth-supported. Study of 43 patients with a follow up of 1 year.Objective.The aim of this study is to compare functional efficiency and patients satisfaction between tooth-supported andimplant-supported overdenture through a questionnaire that accurately reflects the real concerns of patients with dentalprosthesis.Methods.Forty-three patients were selected from the out patient clinic, Department of Dentistry “Fra G.B. Orsenigo Os-pedale San Pietro F.B.F.”, Rome, Italy.Their age were ranging from 61 to 83 years. Eighteen patients were rehabilitatedwith overdentures supported by natural teeth and twenty-five with overdentures implant-supported. Discussion and Result. The questionnaire proposed one year after the insertion of the prosthetis has showed that thereisn’t difference statistically significant in terms of function, phonetics and aesthetics between overdenture implant-supportedand tooth supported.Conclusions.The results of the questionnaire showed that the patients generally had a high level of satisfaction concernto the masticatory function, esthetics and phonetics. In addition, on average, they haven’t difficulty in removal and inser-tion of the denture and in oral hygiene. They haven’t in both groups problems related to fractures
Full-arch maxillary rehabilitation fixed on 6 implants
Full text linkThe purpose of this study is to report a case of full-arch rehabilitation on six endosseous implants loaded following the standard procedure. An implant-prosthetic treatment was proposed to a 53-year-old woman with a total prosthesis in the upper jaw. Six implants on upper maxillary were placed keeping the upper complete denture during the osseointegration period. The implants were left submerged to allow the patient to wear removable prostheses and the prosthesis was rebase with Hydrocast to not compress the sites of healing during the osseointegration period. The impression of implants was made with silicones for addition (VPS) with different viscosities after 8 weeks. The final restoration was carried out taking into account the aesthetic and functional canons. Correct diagnosis and accurate implant planning are key for success in implant rehabilitation
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Restoration of anterior teeth using an indirect composite technique. Case report
Full text linkThis article presents a case report of restoration of anterior teeth using an indirect technique with composite
veneers in order to restore the dental anatomy and to provide aesthetic and function of anterior teeth. A treatment of upper anterior teeth with indirect microhybrid composite restoration was proposed to a 40-year-old woman with old discolored and fractured ceramic veneers. Upper six anterior teeth were prepared and, after impressions with VPS of maxillary arche, the composite veneers were placed. There are several advantages offered by indirect techniques compared to direct techniques. The increased practice of veneering technique with indirect composites is due to improvement in the properties of composite materials in the last years. The results are very favourable and the patient is satisfied. The restorations with composite veneers have proved durable and aesthetic, protect tooth structure and aesthetic and function is predictably
re-established
Prosthetic-restorative approach for the restoration of tooth wear. Vdo increase, rehabilitation of anatomy and function and aesthetic restoration of anterior teeth. Case report
Full text linkObjective: This article presents a case report of combined prosthetic-adhesive rehabilitation in a patient with a generalized tooth wear.
Methods: A combined treatment adhesive - prosthetic was proposed to a male patient of 65 years old having a clinically significant tooth wear, with dentine exposure and with a reduction in clinical crown height. The erosive/abrasive worn dentition have been reconstructed with direct resin composite restorations on the posterior teeth and with zirconia crown on the anterior teeth.
Results: Direct composite restorations have a number of distinct advantages. These restorations have proved durable and aesthetic, protect tooth structure and posterior occlusal contact is predictably re-established.
Conclusions: A combinations of direct and indirect restorations, based on the new vertical dimension of occlusion (VDO), can help to reestablish anatomy and function
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
