Nano‐hydroxyapatite‐coated PEEK implants: A pilot study in rabbit bone
Sargon Barkarmo,Ann Wennerberg,Ann Wennerberg,Maria Hoffman,Per Kjellin,Karin Breding,Paul Handa,Victoria Franke Stenport +7 more
TL;DR: Higher mean bone-to-implant contact indicated better osseointegration in the coated implants than in the uncoated controls, and the large number of lost implants was interpreted as a lack of primary stability due to implant design.

In vitro evaluation of barrier function against oral bacteria of dense and expanded polytetrafluoroethylene (PTFE) membranes for guided bone regeneration.
TL;DR: All PTFE membranes were effective barriers against bacterial passage in vitro, however, d-PTFE favored S. oralis biofilm formation.

The effect of hydroxyapatite nanocrystals on early bone formation surrounding dental implants
Lory Melin Svanborg,Maria Hoffman,Martin Andersson,Fredrik Currie,Per Kjellin,Ann Wennerberg,Ann Wennerberg +6 more
TL;DR: The present study could not support the importance of nanometer thick coatings of hydroxyapatite nanocrystals in early bone healing, at least not when applied on a blasted and etched surface and placed in a cortical bone.

A novel soft tissue model for biomaterial-associated infection and inflammation – Bacteriological, morphological and molecular observations
Sara Svensson,Margarita Trobos,Maria Hoffman,Birgitta Norlindh,Sarunas Petronis,Jukka Lausmaa,Felicia Suska,Peter Thomsen +7 more
TL;DR: A soft tissue infection model was developed, allowing detailed analysis of early events in inflammation and infection associated to biomaterials in vivo leading to insights into host defence mechanisms in biomaterial-associated infections.

Early biocompatibility of poly (ethylene glycol) hydrogel barrier materials for guided bone regeneration. An in vitro study using human gingival fibroblasts (HGF‐1)
TL;DR: Modifications of the physio-chemical properties of PEG hydrogels and the addition of RGD and spacers influenced the initial cellular response of cultured HGF-1 cells and should be considered when developing PEG-based material for clinical purposes.
