Ti6Al4V-Ag 3D Multi-Materials fabricated by Laser Powder Bed Fusion for Biomedi...
Rodrigues, Flávio Gabriel Silva; Bartolomeu, Flávio; Silva, Filipe Samuel; Madeira, Sara Cristina SoaresBiomedical implants often face two major challenges after implantation: post-surgical infections and poor osteointegration. Recent advances suggest that applying electrical current is a promising strategy to address both complications. In this context, a new implant design is proposed that combines the intrinsic properties of Ti6Al4V and Ag(silver). Ti6Al4V, a titanium alloy, is widely used for implants because...
Tratar dentes hipomineralizados (MIH) com coroas flexíveis ultrafinas para uma ...
Silva, Filipe Samuel; Rodrigues, Flávio Gabriel Silva; Arieira, Ana Filipa Amorim; Madeira, Sara Cristina Soares; Pinto, João Pedro FigueiredoEsta comunicação irá apresentar coroas de cor próxima da dos dentes, ultrafinas, flexíveis, personalizadas, ideais para dentes hipomineralizados em crianças. O uso destas coroas não requer qualquer preparação dentária, anestesia, brocagem, não provocando qualquer dor, e garantindo uma proteção dentária prolongada. Este tratamento é o mais adequado para crianças assim como para dentistas pediátricos. Além disso,...
The possibilities and challenges of personalized pediatric dentistry
Silva, Filipe Samuel Correia Pereira da; Pinto, João Pedro Figueiredo; Rodrigues, Flávio Gabriel Silva; Arieira, Ana Filipa AmorimPersonalized dental treatment consists of providing solutions adapted to the patient and not using standard solutions for all patients. This applies in domains as diverse as the use of diagnostic tests to identify particular biological markers, often genetic, that aid in describing which medical treatments to prescribe, as well as providing dental treatment technique, including personalized medical devices that...
Customized approaches - a road to minimally invasive treatments
Silva, Filipe Samuel; Rodrigues, Flávio Gabriel Silva; Arieira, Ana Filipa Amorim; Madeira, Sara Cristina Soares; Pinto, João Pedro FigueiredoPersonalized dental treatment consists of providing humanized and human individuality cenetred approaches, instead of standard solutions. This applies in domains as diverse as the use of diagnostic tests to identify particular biological markers that aid in describing which medical treatments to prescribe, as well as in providing dental treatment techniques, including medical devices that will work best for eac...

Rodrigues, Flávio Gabriel Silva; Pereira, Helena Filipa Ribeiro Silva; Pinto, João Pedro Figueiredo; Padrão, Jorge; Zille, Andrea; Silva, Filipe SamuelTooth loss during the lifetime of an individual is common. A strategy to treat partial or complete edentulous patients is the placement of dental implants. However, dental implants are subject to bacterial colonization and biofilm formation, which cause an infection named peri-implantitis. The existing long-term treatments for peri-implantitis are generally inefficient. Thus, an electrical circuit was produced ...
Ti6Al4V-Ag active antibacterial surfaces by laser powder bed fusion for biomedi...
Rodrigues, Flávio Gabriel Silva; Faria, Ana; Bartolomeu, Flávio; Silva, Filipe Samuel; Madeira, SaraBacterial infections pose significant challenges in biomedical applications, often leading to severe complications. The traditional reliance on antibiotics to manage these infections is rapidly increasingly the antibiotic-resistant bacteria problem. This resistance makes many conventional treatments less effective, encouraging the interest of new approaches that do not rely on antibiotics. Consequently, the dev...
Tribological behavior of TiO2 PEEK composite and stainless steel for pediatric ...
Arieira, Ana Filipa Amorim; Madeira, Sara Cristina Soares; Rodrigues, Flávio Gabriel Silva; Silva, Filipe SamuelDental decay still presents a major health problem among children. Its treatment usually requires the use of stainless steel crowns. This study compares the wear behavior of 316 L stainless steel and polyetheretherketone (PEEK) composite under identical test conditions. The wear tests were conducted in a reciprocating ball-on-plate tribometer (Plint TE67/R) using alumina balls as a counterface and artificial sa...
Innovative piezoelectric composite material for Footwear Soles with antibacteri...
Rodrigues, Flávio Gabriel Silva; Silva, Filipe Samuel; Bartolomeu, Flávio; Madeira, Sara Cristina Soares; Pinto, João Pedro Figueiredo[Excerpt] Bacteria possess remarkable adaptability, and their escalating resistance to antibiotics poses a formidable challenge to public health. Thus, the exploration of alternative strategies becomes essential in addressing surface contamination by bacteria. To develop effective preventive measures, it is crucial to comprehend the mechanisms underlying bacterial adhesion and biofilm formation[1,2]. Although a...
When modified Peek based composite may be superior to Stainless Steel, for pedi...
Silva, Filipe Samuel; Carvalho, Óscar Samuel Novais; Pinto, João Pedro Figueiredo; Madeira, Sara Cristina Soares; Arieira, Ana Filipa AmorimBackground: This in vitro study provides evidence of mechanical, mechanical fatigue, wear, abrasion, biological, anti-bacterial, adhesion, and color properties, of both a modified Peek-based composite (mPbc) and stainless steel (SS), to compare both materials for application in pediatric crowns. Methods: The following tests, representing different intra-oral conditions, were performed: Strength and elasticity/g...
Design and development of a dental implant with electrical stimulation functions
Rodrigues, Flávio Gabriel SilvaThe loss of permanent teeth is a problem that affects a significant part of the world's population and which reveals itself as a real trauma in any person’s life. This loss can result from several causes such as periodontitis, dental caries, trauma, development defects, genetic disorders, among others. To restore the oral health of a person who suffers from this type of problem, dental medicine has already some...
