Journal of Osseointegration 2019-09-13T11:25:12+02:00 Cristina Calchera Open Journal Systems <h1>Journal of Osseointegration</h1> <p>The aim of the<strong> Journal of Osseointegration</strong> in the Implant Dentistry field is to publish high quality contemporary, timely, innovative, interesting and clinically relevant information that will be used for improvement of the care of our patients. The rapid growth of research and more application of advanced clinical procedures has led us to start this new journey, that we hope will be a journey of success. The objective of all the people involved in this project will be to present the data in an accurate, fair and unbiased way. Each paper will be given the close attention that it merits and only manuscripts with well designed projects, conducted in a manner that follows sound scientific principles will be accepted. Also the rapidity of the reviewing process will be a key goal, this will be ensured by a web based submission and colse supervision on the reviewing process. A concerted effort will be made to shorten the time between submission, correction, acceptance of the manuscript, online publication, and print publication. We aim also for a high standard of technical editing, which serves to ensure the consistency of the content style and the fact that the language should be as unambiguous and clear as possible. Manuscripts dealing with basic research, biomaterials, tissue engineering techniques, clinical research and technical innovations will be accepted. The help of all involved people will be of outstanding relevance in achieving this mission.<br><em>Access to the contents of the Journal of Osseointegration is open and free to all users: this is our small contribution to global exchange of knowledge. Users can read, download, copy, distribute, print, search, or link to the full texts of our articles.</em></p> Interaction of dental pulp stem cells in bone regeneration on titanium implant. An in vitro study 2019-09-13T11:25:12+02:00 Sushmita Palanisamy chethan kumar J.S chethan hegde Basan Gowda. S. Kurkalli <p class="p1"><span class="s1"><strong>Aim</strong> To investigate <em>in vitro</em> interaction of dental pulp stem cells (DPSCs) in bone regeneration on titanium implants. </span></p> <p class="p1"><span class="s1"><strong>Materials and methods </strong>Dental pulp tissue collected from<span class="Apple-converted-space">&nbsp; </span>extracted teeth without infection was used to obtain DPSCs. The biocompatibility of titanium implant was studied by culturing the DPSCs in conditioned media obtained by incubating the titanium implants for 72 hours. Following which the interaction of DPSCs on titanium implants was checked by wrapping the DPSCs cell sheet on SLA (sandblasted large grit acid etched) treated and smooth implants. </span></p> <p class="p1"><span class="s1"><strong>Results<span class="Apple-converted-space">&nbsp; </span></strong>Cytotoxicity test revealed that the SLA treated implants were biocompatible and did not affect the proliferation rate of DPSCs. Osteogenic study with titanium implant revealed DPSCs have the capacity to undergo osteogenic differentiation in the presences of titanium implants.</span></p> <p class="p1"><span class="s1"><strong>Conclusions </strong>This study postulates that it is possible to construct a biologically modified implant by wrapping the dental stem cell sheet around commercially available implants in order to improve the process of osseointegration as the implant- stem cell complex contains all the factors required for osseointegration.</span></p> 2019-09-13T09:32:40+02:00 ##submission.copyrightStatement## Management of upper odontogenic infections and the role of multidisciplinary treatment 2019-09-13T11:25:12+02:00 matteo trimarchi Alessandro Vinciguerra Andrea Galli Paolo Capparè Raffaele Vinci Mario Bussi <p class="p1"><strong>Aim </strong>Odontogenic sinusitis is a group of infections related to dental conditions. It may involve the paranasal sinuses (upper odontogenic infections, UOs) and cervical-fascial spaces. Proper diagnosis and treatment of dental complications can be challenging due to<span class="Apple-converted-space">&nbsp; </span>unspecific clinical presentation.</p> <p class="p1"><strong>Materials and methods</strong> A retrospective study of 37 patients with acute UOs treated between January 2008 and December 2018 is presented. A clear etiological and chronological relationship between the odontogenic focus and sinonasal infection was required for inclusion in the study.</p> <p class="p1"><strong>Results</strong> The causes of UOs were mainly dental implantation (29.8%) and tooth extraction (18.9%). In all cases, UOs were treated with transnasal endoscopic surgery, associated with transoral procedures in 24 out of 37 patients (64.9%). Empirical antibiotic therapy was used in all cases, whereas antibiogram-driven therapy was adopted secondarily in 22 out of 37 cases (59.4%). Surgical success was achieved in 97.3% of patients.</p> <p class="p1"><strong>Conclusions</strong> Multidisciplinary agreement of an otorhinolaryngologist and dental surgeon is a crucial step in proper diagnosis and treatment of UOs. A correct surgical approach and antibiogram-driven therapy are key elements of correct resolution of infection.</p> 2019-09-12T13:04:50+02:00 ##submission.copyrightStatement## Digital impression of teeth prepared with a subgingival vertical finish line: a new clinical approach to manage the interim crown 2019-09-13T11:25:12+02:00 Adolfo Di Fiore Paolo Vigolo Carlo Monaco Lorenzo Graiff Marco Ferrari Edoardo Stellini <p>Intraoral scanner can simplify the prosthodontic workflow with reduction of time, cost and several steps. However, clinic conditions can affect the quality of the digital impressions, especially if the tooth is prepared with subgingival vertical finish line. This report describes a technique to manage the interim crown and to obtain accurate digital impression of an abutment tooth with subgingival vertical finish line without the use of retraction techniques.</p> 2019-09-12T12:52:26+02:00 ##submission.copyrightStatement## Immediate implant replacement after Partial explantation of malpositioned dental implant: Case report and follow-up 2019-09-10T11:20:10+02:00 Maria Eugenia Guerrero Daniel Alonso Espinoza Oswaldo Andree Cáceres <p class="p1"><span class="s1"><strong>Aim </strong>It is not common to report in the literature about complications during intraoral dental implant removal and its immediate approach during implant surgery. This report describes the approach of an intraoperative accident during an explantation and its follow up. </span></p> <p class="p1"><span class="s1"><strong>Case report </strong> In this case, an immediate implant was placed in the presence of an implant remnant left after its partial explantation due to implant fracture during the procedure. A cone-beam CT scan was taken after six months post rehabilitation and revealed bone formation surrounding the replaced implant and the remaining titanium fragment. </span></p> <p class="p1"><span class="s1"><strong>Results</strong> There were no functional or aesthetic alterations that affected the outcome of the treatment after 2 years of follow-up. </span></p> <p class="p1"><span class="s1"><strong>Conclusions</strong> This satisfactory result suggests that this immediate solution can be used to obtain adequate results when failed dental implants cannot be completely eliminated, which reduces the duration of the treatment and the number of surgical procedures.</span></p> 2019-09-10T09:34:28+02:00 ##submission.copyrightStatement##
