Titanium Implants after Alkali Heating Treatment with a [Zn(OH)₄]²⁻ Complex: Analysis of Interfacial Bond Strength Using Push‐Out Tests

Abstract

The obtained results suggest that biochemical bonding at the bone-implant interface, stimulated by the Zn(2+) ion release in combination with mechanical interlocking definitively improved the implant fixation.

Comparison between Zn-modification and groove-formation towards better osseointegration of implant

“…In the Zn-modified sample the surface morphology and the TF-XRD data were consistent with the results reported by previous work [9], and the surface is supposed to be the structure as illustrated in Fig. 5, based on reference 9.…”

“…[7,8]. Alvarez, et al reported that the alkali heating treatment with a [Zn(OH) 4 ] 2-, called Zn-modification, was more effective on bone fixation than other processes [9]. From mentioned above, we can understand that a Zn-modification and a moderate topographic pattern contributed to better osseointegration.…”

“…Zn-modified implants were obtained by treating the groove-formed implants in an alkaline solution containing the [Zn(OH) 4 ] 2-. Modification method was followed to the literature reported by Alvarez, et al [9]. Before the surgical placement the implants were sterilized via dry-heat thermostated oven.…”

Experimental evidence for interfacial biochemical bonding in osseointegrated titanium implants

Effects of zinc-substituted nano-hydroxyapatite coatings on bone integration with implant surfaces

“…The results are similar to those of previous papers. Alvarez et al (2010) demonstrated that implants treated with a solution containing [Zn(OH) 4 ] 2− complex showed increased bone fixation compared with control groups. A Zn-containing α-tricalcium phosphate (αZnTCP) was shown to promote new bone formation (Li et al, 2009).…”
