   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PMMA-cement; torque; tensile tesst; Bone conduction chamber; PTH; rats; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : Intermittently administered PTH is known to increase bone mass in osteoporosis models. We studied its effects in bone repair and implant fixation, using histological and mechanical techniques in rats. LÄS MER

3. 2. Bone-compliant cements for vertebral augmentation

   Författare :Céline Robo; Cecilia Persson; Elizabeth Tanner; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone cement; low modulus; vertebroplasty; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

   Sammanfattning : Acrylic bone cement based on poly(methyl methacrylate) (PMMA) is commonly used during vertebral augmentation procedures for the treatment of osteoporosis-induced vertebral compression fractures. However, the high stiffness of the cement compared to that of the surrounding trabecular bone is presumed to facilitate the formation of new fractures shortly after surgery. LÄS MER

4. 3. Submicron Calcium Phosphate Spheres for Biomedical Applications : Synthesis and Use

   Författare :Tao Qin; Håkan Engqvist; Fredrik Nikolajeff; Jie Huang; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium phosphate; spheres; dentinal hypersensitivity; drug release; tooth bleaching;

   Sammanfattning : Calcium phosphate spheres as biomaterials have been attracting attention in recent years. Calcium phosphate occurs naturally in bone, and a hollow structure could be advantageous for drug loading and release. LÄS MER
