fa Analysis of the influence of the macro- and microstructure of dental zirconium implants on osseointegration: a minipig study جراحی دهان، فک و صورت Oral and Maxillofacial Surgery پژوهشي Research <p> <strong>Objectives</strong></p><p>  It was the aim of this study to analyze the influence of implant design and surface topography on the osseointegration of dental zirconium implants. </p><p> <strong>Study Design</strong></p><p>  Six different implant designs were tested in the study. Nine or 10 test implants were inserted in the frontal skull in each of 10 miniature pigs. Biopsies were harvested after 2 and 4 months and subjected to microradiography. </p><p> <strong>Results</strong></p><p>  No significant differences between titanium and zirconium were found regarding the microradiographically detected bone-implant contact (BIC). Cylindric zirconium implants showed a higher BIC at the 2-month follow-up than conic zirconium implants. Among zirconium implants, those with an intermediate Ra value showed a significantly higher BIC compared with low and high Ra implants 4 months after surgery. <strong></strong></p><p> <strong>Conclusions</strong></p><p>  Regarding osseointegration, titanium and zirconium showed equal properties. Cylindric implant design and intermediate surface roughness seemed to enhance osseointegration. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p> <a href="http://www.oooojournal.net/article/S2212-4403(12)00175-7/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1650&slc_lang=fa&sid=1 Cornelia Katharina Mueller 10031947532846007718 10031947532846007718 Yes Department of Oral and Maxillofacial Surgery/Plastic Surgery, University Hospital, Jena, Germany Philipp Solcher 10031947532846007719 10031947532846007719 No Department of Oral and Maxillofacial Surgery/Plastic Surgery, University Hospital, Jena, Germany Andrè Peisker 10031947532846007720 10031947532846007720 No Department of Oral and Maxillofacial Surgery/Plastic Surgery, University Hospital, Jena, Germany Maia Mtsariashvilli 10031947532846007721 10031947532846007721 No Department of Oral and Maxillofacial Surgery/Plastic Surgery, University Hospital, Jena, Germany Karl Andreas Schlegel 10031947532846007722 10031947532846007722 No Department of Maxillofacial Surgery, University of Erlangen-Nuremberg, Erlangen, Germany Gerhard Hildebrand 10031947532846007723 10031947532846007723 No Institute for Bioprocessing and Analytical Measurement Techniques, Heilbad Heiligenstadt, Germany Juergen Rost 10031947532846007724 10031947532846007724 No Institute for Bioprocessing and Analytical Measurement Techniques, Heilbad Heiligenstadt, Germany Klaus Liefeith 10031947532846007725 10031947532846007725 No Institute for Bioprocessing and Analytical Measurement Techniques, Heilbad Heiligenstadt, Germany Jiang Chen 10031947532846007726 10031947532846007726 No Department of Dental Implantology, Affiliated Stomatologic Hospital of Fujian Medical University, Fuzhou, China Stefen Schultze-Mosgau 10031947532846007727 10031947532846007727 No Department of Oral and Maxillofacial Surgery/Plastic Surgery, University Hospital, Jena, Germany
