Extraoral alar base cinch. A modification for the technique

The alar base widening is directly related to the Le Fort I osteotomy which could lead to an undesirable facial change if not adequately controlled transoperatively. Several surgical techniques to control the lateralization and widening of the nasal base have been described in the literature. The extraoral technique, first described by Shams and Motamedi in 2002 seems to make this procedure more predictable and reliable. The authors preset a modification for that technique. © 2013 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.

Propomos nesta monografia o projeto de um escritório de arquitetura anexo a um canteiro escola, tendo como objetivo capacitar pessoas das comunidades periféricas em Presidente Prudente. Ao levar o arquiteto para dentro desta problemática das cidades, ajudaremos a sanar os problemas arquitetônicos de moradias sem qualidade nas comunidades carentes. O canteiro escola é um local onde a população irá aprender a teoria e prática da construção civil e, a partir deste momento, efetuar a autoconstrução de maneira correta eatingir a profissionalização. O Canteiro Escola acontecerá em contêineres de carga modificados, esta estrutura já possui adequação para transporte e, se necessário, poderá haver movimentação entre os bairros da cidade

Avaliação dos resíduos sólidos gerados no Restaurante Universitário da UNESP de Rio Claro: uma análise do potencial de compostagem

A consequence of population growth is the increased generation of solid waste, which requires environmentally and economically viable suitable disposal sites. The scarcity of such sites makes necessary to adopt non-generation measures, reduction, reuse , recycling and treatment of solid waste before final disposal of waste. This paper presents the quantification and qualification of organic waste generated in each sector of the University Restaurant (UR) , by proposing indicators of waste generation per meal (index of waste) . Then, from the characterization of the waste management practices adopted internally, evaluates the potential deployment of the composting process for organic waste, with signaling for opportunities to improve waste management. The diagnosis of waste generation was made based on data collected during the period of 10 days. The waste were classified into 3 groups (organic, recyclable and waste) in each sector of the restaurant ( pre preparation , kitchen and tray return) . The results reveal that 33 % of the waste generated in the UR currently has the potential to be composted in a suitable place on campus. Every meal served generat approximately 124g of waste, of which 35g are organic waste of the pre preparation sector, 49g are remnants of food in the tray’s return and 40g are other kinds of waste, including recyclable and non recyclable. You can still get a higher percentage of compostable if the trays pre-wash is not performed with detergent and water. To minimize the generation of waste trays can be replaced by plates and skimmers and ladles can be replaced by smaller ones. The food exposed in the counter but not consumed, can be distributed to students after the restaurant is closed so this material would not be disposed in the garbage

Reabilitação total da maxila com enxerto intraoral: relato de caso

The early tooth loss and periodontal disease often leave inadequate bone volume for installation of osseointegrated implants. The autogenous bone graft is considered the gold standard for reconstruction of residual bone defects. Some surgical techniques can be performed, including extra or intraoral donor sites depending on the degree of bone loss, depending on surgical-prosthetic planning and general condition of the patient. The intraoral bone grafts offer a safe option to rebuilt bone volume in smaller rehabilitations, with low morbidity and minimal postoperative discomfort. Among the possible donor sites, the mandibular ramus and body, which offer predominantly cortical bone, and the chin area, which offers corticomedullary bone tissue, can be harvested. The graft will be suitable both in quantity and quality, preserving the capacity of osteogenesis, osteoinduction and osteoconduction, which differentiate autogenous grafts from other biomaterials. The aim of this study was to report a clinical case in which the mandibular ramus graft was used for total reconstruction of an edentulous maxilla, showing that even large areas can be reconstructed with grafts from intraoral origin. All the steps that allowed the complete reconstruction of the maxilla done by an intraoral donor area are listed in the text, culminating in an extremely satisfactory clinical result.

Healing of implants installed in over- or under-prepared sites: an experimental study in dogs

ObjectiveTo study bone healing at implants installed with different insertion torques.Material and methodsIn six Labrador dogs, all mandibular premolars and first molars were extracted. After 4months of healing, flaps were elevated, and two implant sites were prepared at each side of the mandible. In the right side of the mandible, the distal sites were prepared conventionally, while the mesial sites were over-prepared by 0.2mm. As a consequence, a final insertion torque of similar to 30Ncm at the distal and a minimal insertion torque close to 0Ncm at the mesial sites were obtained. In the left sides of the mandible, however, the recipient sites were underprepared by 0.3mm resulting in an insertion torque of 70Ncm at both implants. Cover screws were applied, and flaps sutured to fully submerge the experimental sites. After 4months, the animals were sacrificed and ground sections obtained for histological evaluation.ResultsThe mineralized bone-to-implant contact was in the range of 55.2-62.1%, displaying the highest value at implants with similar to 30Ncm insertion torque and the lowest value at the implant sites with close to 0Ncm insertion torque. No statistically significant differences were revealed. Bone density was in the range of 43.4-54.9%, yielding the highest value at implants with 70Ncm insertion torque and the lowest at the implant sites with close to 0Ncm insertion torque. The difference between the sites of similar to 30Ncm and the corresponding 70Ncm insertion torque reached statistical significance.ConclusionsSimilar amounts of osseointegration were obtained irrespective of the insertion torque applied. Moreover, implants installed in sites with close to 0Ncm insertion torque may properly osseointegrate as well.

Charges: um olhar estereotipado dos professores

O presente trabalho de conclusão de curso, intitulado Charges um olhar estereotipado dos professores, é o resultado de um interesse sobre esse tipo de arte gráfica desde a adolescência atrelada à curiosidade sobre a imagem construída historicamente sobre os professores e sobre sua vida profissional. Este trabalho tem por objetivo analisar os estereótipos que são atribuídos aos professores nas charges procurando observar características de gênero, de vestuário e de caráter psicológico. Para atingir esse objetivo, teve-se o intuito de utilizar como material de pesquisa as charges do autor italiano Francesco Tonucci que publicou mais de mil charges na Itália e na Espanha. Esse autor procura abordar em seus desenhos temas que mostram a educação formal e informal em seu país, criticando à forma como a educação é tratada, essas realidades se encaixam com a do Brasil em muitos aspectos, e são estes aspectos que forneceram dados para analise. Para desenvolver essa pesquisa se utilizara a abordagem qualitativa, seguindo a metodologia de pesquisa documental e bibliográfica. Neste trabalho foram observados os estereótipos atribuídos aos professores e discutiu-se que imagem é transmitida desse profissional por esse suporte de leitura tão popular. Para aprofundar a questão dos estereótipos se realizou leituras de artigos que abordaram a questão dos estereótipos no contexto educacional, além de fontes que forneceram explicações sobre o fundamento histórico que deram razões para que esses estereótipos acontecessem. Quanto às charges se realizou um breve apanhado histórico de como esse tipo de arte gráfica surgiu e porque faz tanto sucesso nos meios de comunicação

Cisto ósseo simples: relatos de casos

Usually diagnosed in routine radiographs, the simple bone cyst occurs infrequently. Etiology is unknown and differential diagnosis has to be made with dentigerous cyst, keratocystic odontogenic tumor, adenomatoid odontogenic tumor, ameloblastoma and central giant cell granuloma. Treatment is surgical, by perforating the cortical bone. In most cases an empty cavity, without any capsule or epithelial covering, is encountered, but it may have a liquid content. Perforation of the mandibular cortical bone elicits a response that results in bone repair of the empty cavity. This article reviews the subject and presents two cases of this entity and discusses the possible factors that could interfere in healing course.

Ciclamato de sódio em refrigerantes de baixa caloria

Sodium cyclamate contents in the widely consumed low calorie soft drinks were determined. Low calorie soft drinks made from cola, guarana, orange, lemon and grape were analyzed following the technique described by Sjörberg and Alanko (1987), with some modifications. The methodology recovery assays were carried out at three spiked levels, and the average recovery of 92.5% and 110.3% were found in cola and guarana, respectively; and the relative standard deviation was of 3.7%. The average sodium cyclamate contents ranged from 27.1 ± 1.1 (cola A) to 127.3 ± 1.5 mg.100 mL-1 (lemon B), indicating that the acceptable daily intake of the sweetener can be easily exceeded after drinking low calorie beverages. All of the analyzed low calorie soft drinks showed sodium cyclamate contents higher than those stated on the label, ranging from 12.9% (cola A) to 19.0% (lemon B). Among 18 low calorie soft drinks analyzed, only four showed the average sodium cyclamate contents in accordance with the maximum limit permitted by Brazilian legislation, that is 40 mg.100 mL-1 of beverage; and in other samples the sweetener exceeded ranging from 74.8% (orange) to 218.3% (lemon B) above of the limit permitted.
