Uma op����o terap��utica para o aumento da faixa de gengiva inserida: o enxerto de tecido conjuntivo livre

Several periodontal procedures have been described in the literature to correct mucogingival alterations or to achieve root coverage. The epithelized free gingival graft is a well established periodontal surgery to increase the width of keratinized gingiva with good stability in the long term follow up. However, this procedure is not commonly used in aesthetic areas since the grafted tissue presents differences of color and contrast. The free connective tissue graft emerges as a viable option to increase attached gingiva in areas where aesthetics results are required. The removal of an epithelized free gingival graft from the hard palate region creates a sore and raw surgical wound that slowly repairs, while the connective tissue graft produces only a line of incision that can be easily sutured promoting a more confortable outcome for the patient. This paper aims to report a case where a free connective tissue graft was used to increase the width of attached gingiva in a tooth with gingival recession. This technique presented satisfactory esthetics results, with a better contrast and color matching with the surrounding tissues.

Este trabalho apresenta um caso e discute quest��es ��ticas e legais, incluindo a responsabilidade civil, do fornecimento parcial e inadequado de esclarecimentos a um paciente.

Bombeamento e tratamento da fase livre em Aqu��fero Litor��neo

High fuel consumption and its inadequate control in fuel stations caused the pollution of soil and aquifers. These consequences created more concern with the increased exploration of aquifers to supply the groundwater demand. The objective of this study was to evaluate the eficiency and efectiveness of the of pump and treat technique of the water applied to the Coastal Aquifer in the cleaning up of the plumes produced by the leaking of fuel in the gas station Auto Posto Ba��a do Sol Ltda. The gas station is located in S��o Sebasti��o, in the north coast of S��o Paulo State. In the case of Auto Posto Ba��a do Sol Ltda., the technique of pump and treat was eficient and the plume produced by the leakage was completely removed. However, the efectiveness of this technique was low due to the long time required for the complete operation.

Fatores biomec��nicos relevantes na sele����o dos grampos em pr��teses parciais remov��veis com extremo livre: estudo cl��nico

The free-end removable partial dentures (RPD) shows a complicated and peculiar biomechanical behavior that impose high occlusion forces to the abutment teeth. By this way, the aim of this study was to evaluate the several factors that influence the clasps indication to free-end RPD. It was analysed 84 designed and planned study models of 71 patients, involving 130 clasps near-by a free-end; followed by clinical and radiographical informations. It was observed that bar clasps (���T���, ���Tmod���, ���i���) were used in 88.46% of abutment teeth. In the others (11.55%), it was used simple, combinated or ring circumferential clasps, and MDL. In abutment teeth with high equator line the ���i��� clasps were predominant (48.48%). The ���Tmod��� clasps were predominant in abutment teeth with low equator line (50%) or in middle third (51.35%) and ���T��� clasps were predominant in inclined equators with mesio-buccal (56.52%) or disto-buccal (66.66%) retention. In the posterior abutment teeth, it was prevalent the distal rest (63.52%) and embracing to the adjacent tooth. Some others factors like long clinical crown (5.38%), wrong position of abutment teeth (4.61%), aesthetics (3.07%), retention in alveolar ridge (2.3%), fragility of abutment teeth (1.53%), short clinical crown (0.76%) and short space to the clasp (0.76%) influenced directly during the clasps selection. Factors like mobility of abutment teeth, height of muscular insertions, depth of buccal fornix and antagonist arch acted like secondary factors. After the informations analysis it may be concluded that the bar clasps with distal rest and embracing to the adjacent tooth were the most indicated to free-end RPD

Reabilita����o Oral: pr��tese livre de metal, Remov��vel e implantes. Um caso de 12 anos de acompanhamento

The literature has suggested that the association of removable partial dentures with dental implants can improve the quality of life of patients. Thus, the purpose of this study was to present a case report. This case report describes the development of a removable partial denture associated with dental implants bilaterally been monitored for 12 years, and the efficacy of the proposed treatment. The radiographic controls demonstrated no changes on bone tissue. The maxillary arch was rehabilitated with metal-free crowns. The patient was fully satisfied with this technique providing stability, esthetics, and proper function. It was concluded that the technique of using removable partial dentures associated with dental implants is viable and show the advantages of improved function, aesthetics and cost reductions in rehabilitation treatment.

Influ��ncia do formato do rebordo alveolar sagital em reabilita����es com associa����o de pr��tese parcial remov��vel de extremidade livre e implante ��sseo integrado

The association of mandibular distal extension removable partial dentures with an osteointegrated implant is a treatment option at hasn't been fully explored by modern rehabilitation dentistry yet. The objective of this study is to evaluate, by means of the bidimensional method of finite elements, the distribution of tension on the structures supporting the distal extension removable partial denture (DERPD), associated to a 10.0 x 3.75 mm osteointegrated implant with an ERA retention system, in alveolar ridges of different shapes. Eight models were created, representing, from a sagittal perspective: Model A (MA) ��� a half arch with a horizontal ridge without posterior support, with the presence of the lower left canine, and a conventional DERPD, with metallic support in the incisal aspect of this canine, as replacement for the first and second pre-molars and the first and second molars of the lower left half arch; Model B (MB) ��� similar to MA, but different because of the presence of a 3.75 x 10.00 mm implant with an associated ERA retention system in the posterior region of the DERPD base; Model C (MC) - similar to MA, however with a distally ascending ridge format; Model D (MD) ��� similar to MC, but different because there is an implant associated to a retention system; Model E (ME) - similar to MA, however with a distally descending ridge format; Model F (MF) ��� similar to ME, but ditfferent in the sense that there is an implant with an associated ERA retention system; Model G (MG) ��� similar to MA, however with a distally descending-ascending ridge format; Model H (MH) ��� similar to MG, but different in the sense that there is an implant with an associated ERA retention system. The finite element program ANSYS 9.0 was used to load the models with vertical forces of 50 N, on each cuspid tip. The format of distal descending edge (ME and MF) was that presented worse results, so in the models with conventional RPD as in the models with RPD associated to the implant and ERA system of retention, for the structures gingival mucosa and tooth support. 1) the distally descending ridge presented the most significant stress in the model with the conventional RPD (ME) or with a prosthesis associated to an implant (MF) and 2) the horizontal ridge (MB) provided more relief to the support structures, such as the tooth and the spongy bone, when there was an implant associated to an ERA retention system. The incorporation of the implants with the ERA system retention, in the posterior area of the toothless edge, it promotes larger stability and retention to PPREL, improving the patient's masticatory acting and, consequently, its comfort and function.

An��lise das rela����es entre par��metros geol��tricos e vaz��es para o aqu��fero livre de Ca��apava do Sul - RS

The geophysical methods may be employed in aquifer system studies, as determination of groundwater level, soil/rock contact, beyond estimative of the aquifer thickness horizon. The geoeletric methods are particularly relevant in evaluations of the oilfields systems, due to directs relations between porosity and electrical resistivity, which allow inferences about oil and gas production. The indirect estimative of the productions in free aquifers system is something complex before of the diverse variables responsible for factors or physical phenomena, as clays minerals, which conditioned the physical parameters by electric geophysical methods. This paper present analyzed correlation among electrical resistivity, chargeability and direct measure flow in shallow wells, for determination of statistical relationships between parameters and evaluation of the geological constraints evolved. The study count with the 23 shallow wells located in free aquifer, constituted by alteration materials of the granites localized in Ca��apava do Sul (RS). The geophysical data are acquired by vertical electric sounding in Schlumberger array. The correlations between electrical resistivity and flow, chargeability and flow, thickness of the soil/saprolite and flow indicated relationships between physical and hydrogeologic parameters, with variations conditioned by factors as porosity, permeability, besides intrinsic geological heterogeneities such soil variable thickness and rock fragments with several alteration degrees.

Livre-arb��trio e a rela����o mente e c��rebro em Benjamin Libet

My purpose is to reflect critically on how Benjamin Libet interprets his experiments, which are focused primarily on the question of free will. These experiments have often been considered as scientific evidence against free will, to the extent that they would have shown that the intention and will result from conscious brain processes, which are unconscious and precedents. But that is not the position of Libet, which distinguishes intention and conscious will, arguing that only the first results from previous and unconscious brain processes, while the second is autonomous and able to act causally on brain. Thus, Libet choose to ignore the suggestion of its initial experiments, that is, that all mental events result of specific brain processes. I argue that Libet ignores it because he is not able to understand how mental events, being essentially separated and at the same time the result of brain activity, could act causally on the brain.

Proposta de um sistema de monitoramento do processo de retifica����o plana baseado em plataforma de hardware livre e sensor de baixo custo

O processo de retifica����o �� considerado um dos ��ltimos na cadeia de produ����o de pe��as de precis��o. Assim, �� essencial ter um sistema de monitoramento confi��vel para este processo. Neste trabalho �� proposto um sistema de medi����o de vibra����o, r��pido e vers��til, baseado na plataforma de prototipagem eletr��nica de hardware livre Arduino, com objetivo de monitorar em tempo real o processo de retifica����o plana, especialmente no que diz respeito �� condi����o da pe��a retificada. Para este trabalho ensaios experimentais foram realizados numa m��quina retificadora plana, empregando um rebolo de ��xido de alum��nio e uma pe��a de a��o ABNT 1020. Por meio de um sensor piezel��trico de PZT (Pb-Lead Zirconate Titanate) de baixo custo, instalado junto �� pe��a e conectado a uma das portas anal��gicas do hardware, foi poss��vel medir o sinal de vibra����o durante o processo de retifica����o. Verificou-se que, a medida com que o rebolo perdia sua capacidade de corte, em fun����o das consecutivas passadas sobre a pe��a, ocorria tamb��m uma significativa diminui����o dos valores m��dios do sinal de vibra����o. Tal diminui����o do sinal de vibra����o pode indicar o momento que o rebolo deve ser dressado, permitindo monitorar a qualidade superficial da pe��a durante o processo de retifica����o, evitando danos como �� o caso da queima superficial. O princ��pio de opera����o e as principais caracter��sticas dessa t��cnica foram investigados, bem como algumas de suas limita����es pr��ticas.
