ESTUDO COMPARATIVO DE BIOMATERIAIS TIPO XENOENXERTO E ENXERTO ALOPLÁSTICO PARA CIRURGIA RECONSTRUTIVA ALVEOLAR COM TÉCNICA DE SINUS LIFT COM JANELA LATERAL

The materials that we can use as grafting material can have different origins, which in turn conditions their different properties and behaviors. Depending on their ability to interact with the surrounding bone, they can be classified as bioinert or bioactive materials. Bioactive materials are capable of stimulating the formation of bone tissue, bonding directly to the bone, thus forming a strong and unique interface between bone and biomaterial. The graft material, on the other hand, must be biocompatible and resorbable to be integrated into the newly formed bone, which is structurally similar to bone, osteoconductive and, if possible, also osteoinductive and osteogenic. When we work on the bone regeneration process, we must also take its structure into account.Os materiais que podemos utilizar como material de enxerto podem ter origens diversas, o que por sua vez condiciona as suas diferentes propriedades e comportamentos. Dependendo da sua capacidade de interagir com o osso circundante, podem ser classificados como materiais bioinertes ou bioativos. Os materiais bioativos são capazes de estimular a formação de tecido ósseo, unindo-se diretamente ao osso, formando assim uma interface forte e única entre osso e biomaterial. O material de enxerto, por outro lado, deve ser biocompatível e reabsorvido para ser integrado ao osso neoformado, que é estruturalmente semelhante ao osso, osteocondutor e, se possível, também osteoindutor e osteogênico. Quando atuamos no processo de regeneração óssea devemos também levar em consideração a sua estrutura

UTILIZAÇÃO DA HIDROXIAPATITA DE CÁLCIO E ÁCIDO HIALURÔNICO (HArmonyCaTM) COMO PREENCHEDOR FACIAL

The human being throughout history has always sought beauty, which is demonstrated through philosophy and art. Several areas of study have emerged with the aim of enabling men to achieve physical beauty, among them, Cosmetic Dentistry. Among the procedures offered by cosmetic dentistry, we can highlight fillers with hyaluronic acid and calcium hydroxyapatite, as they are responsible for restoring volume and skin support with immediate results and at the same time stimulating collagen in the long term. In this study, a clinical case using the HArmonyCaTM was reported. And in the end, it can be concluded that the use of HarmonyCATM, presented itself as an excellent alternative for patients who seek volumization and stimulation of facial collagen, proving to be effective in the harmonization and balance of facial structures.O ser humano ao longo da história sempre buscou o belo, sendo demonstrado por meio da filosofia e pela arte. Várias áreas de estudo surgiram com a finalidade de possibilitar ao homem alcançar a beleza física, dentre estas, a Odontologia Estética. Entre os procedimentos ofertados pela odontologia estética podemos destacar os preenchedores com ácido hialurônico e hidroxiapatita de cálcio, pois são responsáveis por devolver o volume e a sustentação da pele com resultados imediatos e ao mesmo tempo estimular colágeno a longo prazo. Neste estudo relatou-se um caso clínico utilizando-se o HArmonyCaTM. E ao final pode-se concluir que o uso do HarmonyCATM, apresentou-se como uma excelente alternativa para pacientes que procuram volumização e estimulação de colágeno da face, demonstrando-se eficaz na harmonização e equilíbrio das estruturas faciais

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
