2. 1. Nano-porous Alumina, a Potential Bone Implant Coating

   Author : Marjam Karlsson; Karin Caldwell; Mats Boman; Matteo Santin; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Nano-porous aluminium oxide; Biomaterial; Hard tissue implant; Surface topography; Osteoblast; Biocompatibility; Neutrophil; Inflammation; Kemi; Chemistry; Kemi;

   Abstract : This thesis describes a method of growing a highly adherent nano-porous alumina coating on titanium implant materials, a design which might be useful in hard tissue replacement. Alumina layers were formed by anodisation of aluminium, which had been deposited on titanium and titanium alloys by electron beam evaporation. READ MORE

   Author : Johan Forsgren; Håkan Engqvist; Strømme Maria; Susanne Bredenberg; Pentti Tengvall; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Controlled release; geopolymer; sol-gel; opioid; oral administration; oral dosage form; implant; titanium; hydroxyapatite; infection; strontium carbonate; strontium; Functional materials; Funktionella material; Materials science; Teknisk materialvetenskap; Material physics with surface physics; Materialfysik med ytfysik; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

   Abstract : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. READ MORE

5. 3. The peri-implant tissues from an esthetic perspective

   Author : Moontaek Chang; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical; dental implants; esthetics; single-tooth replacements; soft tissues; infra-occlusion; bone alterations;

   Abstract : The overall objective of the thesis was to evaluate the dimensions and position of peri-implant soft tissues in relation to the topography and alterations of the bone support, and the tissues’ significance for an esthetic appreciation of implant therapy. A comparative evaluation of crown and soft tissue dimensions between implant-supported single-tooth replacements and the contra-lateral natural tooth was made in Study I. READ MORE

6. 4. Ridge alterations following tooth extraction and implant placement

   Author : Giuseppe Cardaropoli; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : The purpose of the present series of investigations was to study the healing following tooth extraction and implant placement. In an animal model, the healing sequence of tooth extraction sites (Study I), the influence of the periodontal ligament (PDL) on the healing of extraction sockets and the effect of various biomaterial on the healing of bone defects (Study II), and the healing of different bone block grafts placed on the surface of a narrow ridge (Study III) were investigated.

7. 5. On the biological response to different biomaterials under normal and irradiated conditions

   Author : Louise Rydén; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; bone; fibrosis; hydroxyapatite; inflammation; irradiation; Osseointegration; silicone; soft tissue; titanium;

   Abstract : There are several challenges when introducing an implant into a host. Concerning soft tissues, major complications are fibrosis and capsule contracture, whereas for bone, failure of osseointegration may occur. READ MORE
