2. 1. On the role of surface properties for implant fixation : From finite element modeling to in vivo studies

   Author : Patrik Stenlund; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Implant stability; Removal torque; Surface roughness; Surface chemistry; Finite element analysis; Experimental; In vivo; Osseointegration; Mechanical loading; Bone regeneration; Biomechanics;

   Abstract : The aim of this thesis was to gain a deeper understanding of the factors contributing to the fixation of bone-anchored implants, especially with regard to surface chemistry, surface topography and implant loading. The methodology used in the thesis ranges from systematic bench studies, computer simulations, experimental in vivo studies, to load cell measurements on patients treated with bone-anchored amputation prostheses.

   Abstract : The overarching objective of this thesis was to develop intervertebral implants for degenerated discs through design, fabrication, and mechanical validation. The research had four primary aims, each addressing different facets of implant development. READ MORE

7. 5. Characterising Dental Implant Surfaces by Topographical, Electrochemical, and Biomechanical Methods

   Author : Johanna Löberg; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Titanium dental implants; 3D-SEM; AFM; Mott-Schottky analysis; surface roughness parameters; biomechanics.;

   Abstract : Replacement of extracted teeth by dental implants was first introduced in the 1950’s. From the beginning, threaded titanium implants with smooth surfaces were used. Later on, screw shaped implants with micro-scaled roughened surfaces were introduced showing bone ingrowth and improved in vivo and in vitro results and good long term stability. READ MORE
