The aim of this study was to evaluate the clinical, tomographic, and histological similarity within the use of HA+β-TCP (Boneceramic) alone or associated with enamel matrix derived (EMD) proteins in sinus lifting procedures with subsequent dental implant placement. We selected two patients with residual bony ridges between 3 mm and 5 mm in height in need of bone grafts. Six months later, eight implants were installed (two implants at each site). Biopsies were made, and the tissue was processed and stained with HE solution. Tomographic evaluation showed bone height gain up to 10.0 mm on average. Histology showed new bone formation for both groups, with similar bone density and trabecular interconnectivity. It can be concluded that the HA+β-TCP graft isolated or associated to EMD provided bone height gain in sinus lifting procedures, with similar clinical, tomographic and histological characteristics.

Na avaliação das propriedades de biomateriais particulados enxertados em cavidades ósseas cirúrgicas, deve-se considerar separadamente dois ambientes diferentes. Em primeiro lugar, o que ocorre diretamente na interface das partículas com o coágulo sanguíneo e o tecido de granulação, inclusive a osteogênese? Em segundo, o que ocorre nos espaços entre as partículas, distante de sua superfície: quais as reações teciduais induzidas, inclusive a osteogênese? Nesses espaços, como evoluem o coágulo sanguíneo, o tecido de granulação e a neoformação óssea? A mais preponderante das reações frente aos biomateriais particulados deve estar relacionada com o que ocorre diretamente sobre a superfície das partículas e se, ao longo do tempo, essas partículas serão ou não reabsorvidas para dar lugar ao tecido ósseo e restabelecer por completo a normalidade no local.

OBJETIVO: A análise morfológica da estrutura óssea de C2, em pacientes com artrite reumatoide, com o objetivo de aumentar a segurança de procedimentos de estabilização desta vértebra. MÉTODOS: Analisamos retrospectivamente 20 tomografias de coluna cervical realizadas em pacientes com artrite reumatoide, foram medidos os seguintes parâmetros: o ângulo espinolaminar, espessura e comprimento da lâmina de C2. RESULTADOS: Os valores médios encontrados são: espessura das lâminas direita 5,92mm e esquerda 5,87mm; comprimento das lâminas direita 27,75mm e esquerda 27,94mm e ângulo espinolaminar 44,7(0). CONCLUSÃO: Os valores obtidos são compatíveis com os de estudos realizados em indivíduos normais publicados por outros autores, não havendo aparente necessidade de alteração na técnica para colocação dos parafusos. Nível de Evidência IV, Série de casos.

In this work we present the description and analysis of the clitics collocation patterns in prepositional infinitive sentences within the Brazilian writing in the centuries XIX and XX. The corpus in analysis is comprised of letters of newspaper readers and newspaper writers, as well as of advertisements (ads) taken from Brazilian newspapers from different regions / states – Rio de Janeiro, Bahia, Ceará and Pernambuco – and written in the Centuries XIX and XX. They belong to the common minimum corpus of the project named Projeto para a História do Português Brasileiro (PHPB or Project to the History of the Brazilian Portuguese, in English). Its analysis is based on theoreticalmethodological postulates of the Theory of Variation and Change (WEINREICH; LABOV; HERZOG, 1968[2006]; LABOV, 1972[2008]); on the Theory of Principles and Parameters (CHOMSKY, 1981, 1986) and on the model of Grammar Competition (KROCH, 1989; 2001). By trying to articulate those presuppositions from both the theories we present a proposition of theoretical interface between the Variation Theory and the Grammar one. Concerning the empirical results achieved by means of this research, we could figure that, in the context in which there were prepositional infinitive sentences, the most significant independent variable to the occurrence of the proclisis is the type of preposition that comes before the verb in the infinitive. Before that, we found out that there are prepositions which strongly direct the proclisis, as it is the case of the prepositions in Portuguese sem, por, de and para, with all of them presenting Relative Weights over 0,52. Another important result is the one attested in the data referring the state of Rio de Janeiro (RJ). This state is the only one of the sample which is located in the Southeastern region and also presents itself as the main proclisis conditioner amongst the localities pertaining to the sample. In order to explain those results, we raised the hypothesis that the proclisis implementation may be more advanced in the Southeastern than in the Northeastern Brazil, however that hypothesis must be confirmed or refuted in future works. We also present, in this work, a theoretical explanation about the clitics colocation in prepositional infinitive sentences within the Brazilian writing in the XIX and XX centuries. The theoretical explanation we found to interpret the achieved results associates Magro’s proposition (2005), regarding the existence of prepositions occupying the nucleus PP and the existence of prepositions which can play the role of a completer and occupy the nucleus CP, according to Galves (2000; 2001), regarding the existent relation between the clitic colocation and the association of traits-phi to the functional categories COMP, Tense and Person. Our proposition is that the occurrence of prepositions which occupy the nucleus CP causes changes in the values attributed to the traits-phi and to the strong Vtraits in the functional categories COMP, Tense and Person. Thus, we defend that proclisis in Brazilian Portuguese (BP) is derived from the movement of the verb to the functional category tense in which there is the association of traits +V and traits +AGR, what legitimates the proclisis according to Galves´s proposition (2000; 2001).
