2. 1. Aspects of oral implant technology and osseointegration

   Author : Rainde Naiara Rezende de Jesus; Malmö universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; oral implants; surface topography; surface roughness; surface energy; surface wettability; hydrophilicity; macrogeometry; implant body; thread design; surgical protocol; oversized drilling; osseointegration; bone-to-implant contact; bone density; primary implant stability; insertion torque; removal torque; removal energy; connection stiffness; osteoclasts; RAW264.7 cells; gene expression;

   Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.

4. 2. Antennas, Wave Propagation, and Localization in Wireless Body Area Networks

   Author : Rohit Chandra; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Body Area Network; WBAN; body sensor network; body-centric communication; wearable devices; ear-to-ear propagation; antennas; analytical propagation model; localization; wireless capsule endoscopy; in-mouth device; implants;

   Abstract : A network of communicating wireless devices that are implantable, wearable or within close proximity of a human body is called wireless body area network (WBAN). The propagation channels for the devices in the WBAN are either through the body or over the body. READ MORE

5. 3. Osteoarthritis of the Hip and Uncemented Total Hip Arthroplasty : Effects of Immediate Weight Bearing on Implant Stability, Bone Mineral Density, and Body Composition

   Author : Olof Wolf; Hans Mallmin; Sune Larsson; Jan Milbrink; Per Mattsson; Per Adolphson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis of the hip; uncemented; total hip arthroplasty; stability; RSA; BMD; DXA; body composition; weight bearing; Orthopaedics; Ortopedi; Orthopaedics; Ortopedi;

   Abstract : The initial recommendation for the postoperative regime after uncemented total hip arthroplasty (THA) was 6-12 weeks of partial weight bearing (PWB) to obtain a stable implant position during bone ingrowth. In recent years patients with uncemented THA have increasingly practiced full weight bearing (FWB) after surgery, which has largely been based on clinical experience rather than on scientific evidence.

6. 4. Experimental implant-associated orthopaedic infections

   Author : Åke Johansson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Osteomyelitis; anaerobic bacteria; implant design and material; bacterial collagen- and fibronectin-binding;

   Abstract : Although indispensable in today's medicine, orthopaedic implants may also cause adverse reactions. A foreign body increases the local susceptibility to colonisation by microorganisms, and hence the risk of infections. These infections are rare, but many result in prolonged or permanent impairment.

7. 5. On efficacy of implant thread design for bone stimulation

   Author : Ramesh Chowdhary; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Introduction – The mechanism and efficiency of force transfer by dental implants to surrounding biologic tissues are important determinants in the development of the implant-to-bone/tissue interface and implant longevity. Threads are used to improve the initial stability by maximizing bone contact through an enlarged implant surface area and thereby favor distribution of interfacial stresses. READ MORE
