  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. On the tissue response to hafnium, titanium and thin calcium phosphate coatings

    Author : Sham Mohammadi; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hafnium; titanium; calcium phosphates; hydroxyapatite; implants; bone; soft tissue; histomorphometry;

    Abstract : Background: Titanium (Ti) is the gold standard material for load-bearing implants. Although high success rates have been reported for Ti implants, failures do occur. Alternative materials/surface modifications might further improve the performances of Ti implants, particularly in situations with non-optimal local tissue conditions. READ MORE

  5. 3. On a biomechanical approach to analysis of stability and load bearing capacity of oral implants

    Author : Anders Halldin; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animal model; bone resorption; implant stability; cortical bone; viscoelastic-viscoplastic; creep remodeling; constitutive model;

    Abstract : IntroductionWhen an implant is placed in the bone the body responds to thetrauma by encapsulating the implant and its survival depends onthe ability for hard tissue encapsulation. The stability of the implantduring the healing phase is essential to achieve a good result[1]. Biological, physiological and mechanical phenomena affectimplant stability. READ MORE

  6. 4. On magnesium-containing implants for bone applications

    Author : Silvia Galli; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The biomedical technologies for bone application are employed in millions of patients every year to restore function and aesthetics following trauma, diseases and congenital deformities. They achieved significant advancements in the last decades and have resulted in the development of implants that function for long periods of time. READ MORE

  7. 5. Towards better understanding of small joint arthroplasty in the hand. Silicone implants, osseointegrated implants and functional outcome

    Author : Karin Möller; Göteborgs universitet; []
    Keywords : artroplasy; MCP; PIP; osseointegration; hand surgery;

    Abstract : Today the most widely used implants for small joint arthroplasty in the hand are flexible silicone implants, introduced by Swanson in the 1960 s. They are encapsulated by connective tissue, which allows pistoning movements in the bone marrow canal This type of implant, mostly used in rheumatic patients, gives high patient satisfaction, relief of pain, correction of deformity and a changed arc of motion towards a more functional position.
