2. 1. On surgical techniques to increase bone density and volume. Studies in the rat and the rabbit

   Author : Christer Slotte; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autogeneic bone; bovine bone mineral; calvaria; cortical perforation; guided bone augmentation; maxilla; microangiography; morphometry; rabbit; rat; tibia; titanium implants; vessel topography;

   Abstract : BACKGROUND. Various techniques of surgical intervention have been suggested to promote bone densityand volume; however, the predictability of such techniques is not always sufficiently supported by preclinicalevaluations.AIM. READ MORE

4. 2. Fibroblast growth factor-23 and Klotho in bone/mineral and parathyroid disorders

   Author : Tijana Krajisnik; Tobias E. Larsson; Kenneth B. Jonsson; Östen Ljunggren; Peyman Björklund; Gunnar Sterner; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; calcitriol; chronic kidney disease; CKD; chronic renal failure; fibroblast growth factor 23; fibroblast growth factor-23; FGF23; FGF-23; GalNac-T3; GALNT3; GFR; hyperostosis-hyperphosphatemia syndrome; HHS; Klotho; parathyroid hormone; PTH; hyperparathyroidism; pHPT; sHPT; uremic; vitamin D3; Endocrinology; Endokrinologi; Internal Medicine; invärtesmedicin;

   Abstract : Fibroblast growth factor-23 (FGF23) is a novel, bone-produced hormone that regulates renal phosphate (Pi) reabsorption and calcitriol metabolism. Disorders of mineral and bone metabolism, such as autosomal dominant hypophosphatemic rickets (ADHR) and hyperostosis-hyperphosphatemia syndrome (HHS), witness the importance of well-balanced serum levels of FGF23.

5. 3. Bone structure characterisation using neutron scattering techniques

   Author : Elin Törnquist; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanics; neutron tomography; x-ray tomography; small-angle neutron scattering SANS ; small-angle x-ray scattering SAXS ; Experimental mechanics; implant integration; tomography; nanoscale; microscale; mechanical properties;

   Abstract : Bones have unique mechanical properties that originate from their main constituents: mineral, in the form of hydroxyapatite (HAp) crystals, and collagen type-I. The stiffness of the HAp mineral combined with the flexibility of collagen, and their intricate hierarchical arrangement from the smallest individual building blocks to the organ level, result in a composite tissue with a remarkable ability to withstand complex loading scenarios.

6. 4. Clinical and experimental studies of bone substitutes and dental implants in compromised bone sites

   Author : Amela Trbakovic; Andreas Thor; Patricia Hedenqvist; Christer Dahlin; Uppsala universitet; []
   Keywords : clinical follow-up; calcium phosphates; rabbit model; sinus lift; radius model; in vivo; bisphosphonates; narrow diameter implants; dental implants; Oral and Maxillofacial Surgery; Käkkirurgi;

   Abstract : Background: With an ageing population, an increase of more challenging implant treatments is expected. In this thesis, we evaluate the outcome of two faster implant protocols, in patients with compromised alveolar bone. READ MORE

7. 5. Studies on three matrix molecules in bone and dentin

   Author : Ulrika Petersson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Osteoadherin OSAD ; Nucleobindin Nuc ; Calreticulin CRT ; biomineralization; osteogenesis; dentinogenesis;

   Abstract : The biomineralization of bone and dentin is a complex and dynamic process, involving the formation of an organic framework in which mineral crystals are deposited. The noncollagenous proteins (NCPs) of the organic phase play a central role in the extracellular matrix (ECM) organization and mineralization regulation. READ MORE
