Pulsed Laser Deposition of Bioglass Coatings on Dental Implants

Abstract

Bioactive implants coated with Bioglass 45S5 film, as the subject of the research, were produced, evaluation of the adhesion strength of coatings and technology optimisation were carried out with success. In order to have effective deposition technology for dental applications, Pulsed Laser Ablation and Deposition techniques (PLAD) and special equipment was developed as well. The present paper intends to give a summary of the experimental results and the optimisation process itself in case of pilot scale production of dental screws.

Electrophoretic deposition of zirconia‐Bioglass® composite coatings for biomedical implants

“…10 Alternative techniques to plasma spraying of HA and of innovative bioactive coatings have been widely studied. Some examples are radio frequency magnetron sputtering of HA or other calcium phosphates (CaP) including a CaP/Al 2 O 3 composite [11][12][13][14] ; ion beam 15,16 or pulsed laser deposition techniques 17,18 of HA or bioactive glasses; the biomimetic method for HA coatings [19][20][21] ; dip-or spin-coating techniques for HA, CaP, or bioactive glasses [22][23][24][25] ; electrolytic deposition of HA or other CaP compounds, ZrO 2 , and Al 2 O 3 5, [26][27][28][29] ; and electrophoretic deposition (EPD) of different biomaterials ranging from HA 30 to Al 2 O 3 based composites 31 and nacre (mother pearl). 32 Among those, EPD has been identified as a promising technique.…”

“…Bioglass® 45S5 is known for its bioactivity. Several references were considered by the authors about the bioactivity of Bioglass, among those are the book of Hench,41 the review papers of Dubok42 and Stroganova et al,43 and the paper of Kokubo et al44 The use of Bioglass or other bioactive glasses as coating material for metallic implants has been widely investigated,17, 22, 45–47 also proving the durability of the coating after in vitro tests.…”

Bioactive Glass—An Extensive Study of the Preparation and Coating Methods

“…Using pulsed laser deposition, bioactive glass coatings were obtained on scaffolds made of pure titanium [170][171][172] and its alloys [173][174][175][176], stainless steel [177], magnesium [178], and silicon [144,178].…”

“…The characterization of the obtained coatings is performed by specific techniques. For example, scanning electron [174] and energy dispersive spectroscopy EDS [176] are used to characterize the coating morphology. X-ray diffraction is used to study the crystallinity of the obtained coatings [171].…”

Bone Bonding of Hafnium – A Literature Review

“…In this way, the coated titanium implants aid to enhance strong integration by initiation of bone formation (Oates, 2001;miron et al, 2010;bosco et al, 2012;Kohal et al, 2013). many coating techniques have been investigated and implemented such as dry deposition, plasma spraying (yang et al, 2000; Heimann and lehmann, 2015; Xuereb, Camilleri and Attard, 2015); (li et al, 2017), resonance frequency magnetron sputtering (yokota et al, 2014; Das and Shukla, 2020), pulsed laser deposition (garcia-Sanz et al, 1997;Czél, Teghil and Janovszky, 2003), ion beam assisted deposition (Ohtsuka et al, 1994;yoshinari, Klinge and Dérand, 1996), biomimetic deposition (rigo et al, 2004;Zhang, leng and Xin, 2005;fuming, guoli and Xiaoxiang, 2008;Kim et al, 2011;Stefanic et al, 2012), sol-gel deposition (lacefield, 1998), electrophoretic deposition and electrospray deposition (yang et al, 2000; Heimann and lehmann, 2015; Xuereb, Camilleri and Attard, 2015). The concept of type of coatings has drifted from a passive protecting layer in the 1980s to bioactive layers (graber, 1982;manero et al, 2002;Nogueras-bayona et al, 2004).…”
