Journal ArticleDOI
Chemical and biological integration of a mouldable bioactive ceramic material capable of forming apatite in vivo in teeth
Håkan Engqvist,Jan Erik Schultz-Walz,Jesper Lööf,Gianluigi A. Botton,David Mayer,M. W. Phaneuf,Nils-Otto Ahnfelt,Leif Hermansson +7 more
TL;DR: The results showed that a tight bond forms between the filling material and tooth and no gap could be found even at high magnification, and the calcium aluminate system formed apatite in situ during hardening through precipitation.
Journal ArticleDOI
Characterization of the surface properties of commercially available dental implants using scanning electron microscopy, focused ion beam, and high-resolution transmission electron microscopy.
Tobias Jarmar,Anders Palmquist,Rickard Brånemark,Leif Hermansson,Håkan Engqvist,Peter Thomsen +5 more
TL;DR: The provision of osseointegration is not exclusively linked to a particular set of surface features if the implant surface character is a major factor in that process, and the studied methodology provides an effective tool to also analyze the interface between implant and surrounding bone.
Patent
Method of making structured ceramic coatings and coated devices prepared with the method
TL;DR: In this paper, a low temperature method for producing multi-layered or multi-phased coatings with controlled variations in terms of chemical composition, phase composition, porosity, surface roughness, mechanical properties, biocompatibility, etc.
Journal ArticleDOI
Technique for preparation and characterization in cross-section of oral titanium implant surfaces using focused ion beam and transmission electron microscopy.
Tobias Jarmar,Anders Palmquist,Rickard Brånemark,Leif Hermansson,Håkan Engqvist,Peter Thomsen +5 more
TL;DR: This study provides the first set of data for the optimization of a new route for preparation and analysis of biomaterial surfaces and interfaces using FIB for producing electron transparent foils/sections from a metal implant for TEM analysis.
Journal ArticleDOI
A novel tool for high‐resolution transmission electron microscopy of intact interfaces between bone and metallic implants
Håkan Engqvist,Gianluigi A. Botton,Martin Couillard,S. Mohammadi,Johan Malmström,Lena Emanuelsson,Leif Hermansson,M. W. Phaneuf,Peter Thomsen +8 more
TL;DR: By using focused ion beam microscopy for site-specific preparation of TEM samples, intact interfaces between metal implants and calcified tissue were imaged for the first time and fulfilled a long-sought-for demand to correlate the surface properties of implanted metal prostheses with the fine structure and composition of preserved interfaces with tissues.
