Zirconia Dental Implant Materials

Abstract

Ceramic materials are used for the fabrication of dental restorations respectively esthetic dentistry. The main ceramic materials are glass ceramics, spinel, alumina and zirconia. Zirconia was introduced into dentistry domain in the 1990s used like frameworks, implants, dowels, abutments and orthodontic brackets. Recently, zirconia materials are getting much attention for dental implants because of its toothlike color, mechanical properties, good corrosion and biocompatibility. This article presents an review of zirconia dental implants osseointegration and mechanical strength compared with other dental implants. Clinical studies published indicate that zirconia dental implants have the potential to become alternative of titanium dental implants used in medical applications.

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).…”

“…Though these implants were used in clinical practice earlier, another superior substitute ceramic material was introduced later ,the zirconium (Correia et al, 2013;Patil, 2015;focsaneanu et al, 2017;Kaur, Sherrill and Duan, 2019;Kim and lee, 2020). However, failures still exist in these materials in spite of the survival rates of these biomaterials (rajaraman et al, 2018) Methods To Determine Osseointegration: The implant stability can be measured by invasive or non-invasive methods namely, radiography (Nogueira et al, 2006;Atsumi, Park and Wang, 2007);(rajaraman et al, no date;mcfarland, 1954), cutting torque analysis (friberg et al, 1995;Atsumi, Park and Wang, 2007), impact hammer method (Teerlinck et al, 1991;Wijaya et al, 2004), reverse torque test (Sullivan et al, 1996;Simeone, rios and Simonpietri, 2016;Nallaswamy, 2017), insertion torque analysis (Tricio et al, 1995;lages, Oliveira and Costa, 2018), pulse oscillation waveform (meredith, 1998;Atsumi, Park and Wang, 2007) , percussion test (Dario, Cucchiaro and Deluzio, 2002;Vaidya et al, 2017) and resonance frequency analysis (ersanli et al, 2005;Atsumi, Park and Wang, 2007;Deng et al, 2008). radiograph is a noninvasive method but only when demineralization exceeds 40%, it detects the density change (Halse et al, 1994;yang and Dutra, 2005;White and Pharoah, 2018).…”

“…Hafnium belongs to the same period and block as tantalum, in the periodic table (leigh, 2011;Parsons, 2014;Constable, 2019). Previously our department has published extensive research on various aspects of prosthetic dentistry ('evaluation of Corrosive behavior of four Nickel-chromium Alloys in Artificial Saliva by Cyclic Polarization Test:An in vitro Study ganapathy, Kannan and Venugopalan, 2017;Jain, 2017aJain, , 2017branganathan, ganapathy and Jain, 2017;Ariga et al, 2018;gupta, Ariga and Deogade, 2018;Anbu et al, 2019;Ashok and ganapathy, 2019;Duraisamy et al, 2019;Varghese, ramesh and Veeraiyan, 2019), this vast research experience has inspired us to research about This review aims at analysing the existing literature on hafnium as potential implant biomaterial.…”
