On Possibly Bioactive CP Titanium Implant Surfaces
(2009-06-29)Background Osseointegrated titanium implants are routinely used in clinical dentistry. Although the overall clinical results are good, there are situations when an improved implant healing is desirable, for instance in ... -
On the biological behavior of barrier membranes: implications for Guided Bone Regeneration. Clinical and Experimental studies
(2021-12-21)There is a continuous development of bone augmentation solutions to meet the rising demand for effective dental implant rehabilitations. One of the most used techniques is Guided Bone Regeneration (GBR). Although successful ... -
On the biological response to different biomaterials under normal and irradiated conditions
(2022-03-10)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. In addition ... -
On the Bone Tissue Response to Surface Chemistry Modifications of Titanium Implants
(2011-09-12)Background: Surface properties of titanium implants play an important role in osseointegration. From 1990, a lot of engineering techniques have been applied to dental implant productions for improving their clinical ... -
On the diagnosis and treatment of intraepidermal carcinoma
(2023-05-24)Abstract: Intraepidermal carcinoma (IEC), also known as Bowen disease (BD) or squamous cell carcinoma (SCC) in situ, is a precursor to SCC. The incidence of IEC is increasing rapidly in fair-skinned populations with a ... -
On the effect of repetitive loading on the spine of young elite athletes. Clinical and experimental studies
(2016-05-13)Introduction: The human spine is exposed to many different loads during daily activities and especially during sporting activities. The spine has different biomechanical properties during the lifetime and thereby responds ... -
On the influence of micro-and macroscopic surface modifications on bone integration of titanium implants
(2007-01-31)Background: Osseointegrated titanium implants are routinely used in clinical denstistry as anchorage units for dental prostheses. Although the overall clinical results are good, there are clinical situations when an ... -
On the pathogenesis of infections associated with percutaneous osseointegrated orthopaedic implants
(2018-11-22)Orthopaedic implants enable the restitution of locomotor function and improve the quality of life of many people. However, biomaterial-associated infection may occur due to the propensity of microorganisms to adhere and ... -
On the role of surface properties for implant fixation : From finite element modeling to in vivo studies
(2015-05-13)The aim of this thesis was to gain a deeper understanding of the factors contributing to the fixation of bone-anchored implants, especially with regard to surface chemistry, surface topography and implant loading. The ... -
On the treatment of tibial fractures using the Ilizarov fixator
(2014-08-29)The aim of this thesis was to analyse the results of the Ilizarov method in patients with different types of tibial fracture and compare them with conventional methods, in terms of primary union, complication rates, ... -
On tissue engineering of pig, human, and non-human primate tissues
(2020-05-07)Background: Demand for donor organs for transplantation has been increasing every year more than the actual supply of suitable donor organs. One of the major problems associated with allogeneic transplantation includes ... -
On tissue reactions to dentin as a bone substitute material
(2017-08-15)Background Reconstruction of the jaws due to resorption of the alveolar crest may require bone augmentation prior to installation of endosseous implants. Active research on new bone graft materials with bone regeneration ... -
On various protocols for direct loading of implant-supported fixed prostheses
(2007-11-30)Backgrund: Prosthetic rehabilitation of the edentulous patient with implant-supported bridges is today a routine and predictable treatment modality. The original protocol prescribed a healing period of 3 to 6 months prior ... -
Open and closed endotracheal suctioning. Experimental and human studies.
(2007-04-20)Background: The practice of endotracheal suctioning of ventilator treated patients is necessary to remove secretions to prevent obstruction of the endotracheal-tracheal tube and lower airways. This very common procedure ... -
Opportunistic viral infection after paediatric transplantation
(2009-04-17)Background: Opportunistic viral infections can cause considerable morbidity and mortality in organ and stem cell transplanted (SCT) patients, mainly due to iatrogenic T cell dysfunction. Whereas in SCT patients, in general ... -
Optimisation of radionuclide therapy by reduction of normal tissue damage
(2022-05-10)Background:177Lu-octreotate is used to treat patients with neuroendocrine tumours (NETs) often resulting in prolonged life and better quality of life, but is today seldom a cure for these patients. Optimisation of ... -
Optimization of image acquisition parameters in chest tomosynthesis - Experimental studies on pulmonary nodule assessment and perceived image quality
(2016-12-14)Chest tomosynthesis refers to the technique of acquiring a number of discrete projection images within a limited angular range around the patient. These projection images are then used to reconstruct section images of the ... -
Optimization of paediatric CT examinations - An approach to minimize absorbed dose to patients with regard to image quality and observer variability
(2011-02-25)The absorbed dose to paediatric patients is important bearing in mind the increased risk of radiation-induced cancer due to exposure to X-rays at young ages. Questions have also been raised of whether a CT examination of ... -
Optimization of radiotherapy in locally advanced lung cancer
(2011-12-20)Lung cancer is the leading cause of cancer death worldwide as well as in Sweden, where the incidence is around 3500 new cases per year. About 50% have distant metastases by the time of diagnosis and are treated with ... -
