“…Paciente A.P.S., 58 anos, gênero masculino, melanoderma, vítima de acidente motociclístico com trauma em crânio e face, deu entrada no serviço de urgência∕emergência do hospital Porto Dias sendo atendido primeiramente pela equipe de neurocirurgia na qual observou ao exame clínico trauma na região fronto-orbital e ao exame de imagem tomografia de crânio, imagem sugestiva de fratura no complexo fronto-orbital e lesão traumática em dura-máter, então o internou na Unidade de Terapia Intensiva UTI Apesar da crescente frequência da utilização dos biomateriais nas reconstruções faciais em substituição aos enxertos autógenos ainda não existe um critério de seleção para determinar a escolha do biomaterial, sendo a preferência pessoal do cirurgião o fator determinante dessa escolha (MAIA et al, 2010). raras, representando de 1 a 9% de todas as fraturas de órbita.…”

“…Several types of polymers have been studied for biomedical use, such as polymethylmethacrylate (PMMA) (Lee et al 2008) and polyethylene terephthalate (PET) (Liu et al 2005). However, their application as biomaterial depends on characteristics like biodegradability (Maia et al 2010) and bioactivity. Biodegradable synthetic polymers, such as polylactide (PLA) and poly(lactide-co-glycotide) (PLGA), are not sufficiently bioactive and cannot promote cell regeneration (Lee et al 2008).…”

The success of a biomaterial relies on an appropriate interaction between the surface of that biomaterial and the surrounding environment; more specifically, the success of a biomaterial depends on how fluids, proteins, and cells interact with the foreign material. For this reason, the surface properties of biomaterial, such as composition, charge, wettability, and roughness, must be optimized for a desired application to be achieved. In this review we highlight different bioinspired approaches that are used to manipulate and fine-tune the interfacial properties of biomaterials. Inspired by noteworthy natural processes, researchers have developed materials with a functional anatomy that range from hierarchical hybrid structures to self-cleaning interfaces. In this review we focus on (1) the creation of particles and modified surfaces inspired by the structure and composition of biogenic mineralized tissues, (2) the development of biofunctional coatings, (3) materials inspired by biomembranes and proteins, and (4) the design of superwettable materials. Our intention is to point out different bioinspired methodologies that have been used to design materials for biomedical applications and to discuss how interfacial properties modified by manipulation of these materials determine their final biological response. Our objective is to present future research directions and to highlight the potential of bioinspired materials. We hope this review will provide an understanding of the interplay between interfacial properties and biological response so that successful biomaterials can be achieved.

“…The need for bone grafts has been increasing due to surgeries due to traumas, tumors, craniosynostosis and surgeries with aesthetic purposes. 3 Archives in Biosciences & Health, v. 1, n. 1, p. 139-148, jan./jun. 2019…”

“…Some biomaterials can be absorbed by the human body over time, and may stimulate the formation of bone tissue simultaneously, the ideal for these materials is that the rate of degradation of the implanted material coincides with the bone tissue neoformation that the even stimulates, a possible intervention that facilitates the regeneration and adoption of scaffolds to fill the defects and support the natural loads of the fabric. [3][4] Such materials must still have other characteristics so that their use is feasible, in addition to biocompatibility. The success of a biomaterial implant depends on bone-like mechanical properties, simulating the loads that are inserted naturally into the tissue in the most diverse daily activities, ranging from standing still to running.…”

There is a growing demand for bone grafts by various clinical sectors, such as aesthetic procedures, treatment of injuries and dentistry, the use of synthetic materials is shown to be good due to the availability and the reduction of risks that their use brings, among the materials that are used in the clinic can be cited the chitosan matrix composites (CHI) with hydroxyapatite (HA) and carbon nanotubes (CNTs), which uses materials that are already used in the clinic HA and CHI with an innovative material in the sector the CNTs. The aim was to analyze and compare data from the current state of the art of CHI matrix composites with HA and CNTs applied in bone tissue engineering. This study is based on a review of the specialized literature on articles in online scientific journals, with thematic issues related to the properties of the biocomposite on board. The influence of the use on the composite properties generated by the use of CNTs together with the HA in the CHI matrix, for biomedical applications, more specifically in bone tissue engineering, was observed. It was observed that with subtle increases of CNTs in the CH composite Ha composites, the bioactivity, osteoconduction, antibacterial activity, mechanical properties of the composites, changes in the nanotexturas, and a homogeneous distribution of the materials occur, potentiality of its use in more than one application within bone tissue engineering. In the present study it was possible to observe that CHI matrix composites with HA and CNTs present a combination of properties highlighting the potential for application in bone tissue engineering.
