“…7,11,35 Several treatments have been used in studies to improve bonding properties of these materials. 7,15,20,22,24,29,30,36,37 Recently, it has been suggested that the application of plasma can lead to enhanced zirconia-resin bonding by making changes on the surfaces of Y-TZP. [31][32][33] In the present study, we assessed the effects of various types of non-thermal plasmas on Y-TZP in terms of surface properties and bonding strength.…”

Introduction:In recent years, the use of ceramic base zirconia is considered in dentistry for all ceramic restorations because of its chemical stability, biocompatibility, and good compressive as well as flexural strength. However, due to its chemical stability, there is a challenge with dental bonding. Several studies have been done to improve zirconia bonding but they are not reliable. The purpose of this research is to study the effect of plasma treatment on bonding strength of zirconia. Methods: In this in vitro study, 180 zirconia discs' (thickness was 0.85-0.9 mm) surfaces were processed with plasma of oxygen, argon, air and oxygen-argon combination with 90-10 and 80-20 ratio (n=30 for each group) after being polished by sandblast. Surface modifications were assessed by measuring the contact angle, surface roughness, and topographical evaluations. Cylindrical Panavia f2 resin-cement and Diafill were used for microshear strength bond measurements. The data analysis was performed by SPSS 20.0 software and one-way analysis of variance (ANOVA) and Tukey test as the post hoc. Results: Plasma treatment in all groups significantly reduces contact angle compare with control (P = 0.001). Topographic evaluations revealed coarseness promotion occurred in all plasma treated groups which was significant when compared to control (P < 0.05), except argon plasma treated group that significantly decreased surface roughness (P < 0.05). In all treated groups, microshear bond strength increased, except oxygen treated plasma group which decreased this strength. Air and argon-oxygen combination (both groups) significantly increased microshear bond strength (P < 0.05). Conclusion: According to this research, plasmatic processing with dielectric barrier method in atmospheric pressure can increase zirconia bonding strength.

“…Although the chemical properties of the extracellular matrix are well-known regulators of cellular responses, physical properties of the matrix in a 3D scaffold can also play important roles in regulating the initial response of bone cells around the implant [59, 71]. In fact, MSCs are able to sense the roughness, stiffness and texture of their surroundings and then use this information to decide their fate during differentiation [59].…”

Professor Shu Chien is a world-renowned leader and founder of Bioengineering. In particular, he has made seminal contributions to advancing our systematic and insightful understanding of how cells perceive their physical/mechanical environment and coordinate cellular functions. In this review, as part of a tribute to Prof. Shu Chien's scientific achievement, we summarize the research progress in understanding the physiology of bone cells interacting with different mechanical/physical environments during bone tissue regeneration/repair. We first introduce the cellular composition of the bone tissue and the mechanism of the physiological bone regeneration/repair process. We then describe the properties and development of biomaterials for bone tissue engineering, followed by the highlighting of research progresses on the cellular response to mechanical environmental cues. Finally, several latest advancements in bone tissue regeneration and remaining challenges in the field are discussed for future research directions.

“…Estes resultados diferem de outros estudos encontrados na literatura que compararam o efeito de várias superfícies de titânio e observaram que os melhores resultados foram encontrados nas superfícies texturizadas 28,29 , incluindo também os que utilizaram o mesmo tipo de tratamento -nitretação iônica 12,15,16,30 . Todavia, é importante considerar que estes estudos foram realizados com linhagens celulares imortalizadas que exibem potencial para expressar características fenotípicas de osteoblastos.…”

“…Os nitretos e carbetos de titânio são materiais duros que melhoram as propriedades tribológicas da superfície, ou seja, aumentam a resistência ao desgaste e a dureza superficial 13 , favorecendo a adesão e proliferação celular à superfície do material. Estes achados foram comprovados em estudos in vitro utilizando células pré-osteoblásticas MC3T3 12 e Osteo-1 15,16 . Considerando que a nitretação a plasma, assim como outros tratamentos de superfície, influencia o processo de interação célula-superfície, o presente estudo buscou avaliar a capacidade de adesão das células do ligamento periodontal de ratos às superfícies de titânio polidas (P) e nitretadas por plasma (N).…”
