1. Molecular and structural patterns of guided bone regeneration (GBR). Experimental studies on the role of GBR membrane and bone substitute materials
Abstract : The mechanisms of guided bone regeneration (GBR) and bone healing with calcium phosphate (CaP) bone substitutes are not fully understood. The major aim of this thesis was to determine the relationship between the bone formation in bone defects and the cellular distribution and activities in association with CaP materials and/or with GBR membrane.

2. A methodological platform to study molecular biocompatibility of biomaterials. Experimental and clinical studies
Abstract : The aim of this project was to develop a methodological platform in order to advance our scientific understanding of the mechanisms of osseointegration. Screw-shaped, titanium implants, with different surface properties, were inserted in the rat tibia, or incubated in mono- or co-culture of human monocytes and MSCs. READ MORE

3. On 606 retrieved oral and cranio-facial implants. An analysis of consecutively received human specimens
Abstract : Aim:The aim of the present thesis was to histologically and histomorphometrically analyse retrieved human specimens of oral and cranio-facial implants, and to address the clinical relevance of a retrieval bank.Materials and methods:The specimens analysed were submitted to the retrieval bank at the Department of Biomaterials / Handicap Research.

4. Effects of antiresorptive agents on inflammation and bone regeneration in different osseous sites - experimental and clinical studies
Abstract : The biological mechanisms involved in bone regeneration in osteoporotic bone and the effect of antiresorptive drugs in relation to surgically inserted biomaterials are not fully understood. Improved osseointegration of titanium implants but also adverse effects of antiresorptive therapies, such as osteonecrotic jaw have been described in the literature. READ MORE

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