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> https://journalofosseointegration.eu/index.php/jo/article/view/270 Use of monolithic lithium disilicate for implant abutment and crown: a clinical report 2019-07-18T10:08:05+02:00 N. Mobilio farma@ariesdue.it S. Catapano farma@ariesdue.it <p class="p1"><span class="s1"><strong>Background </strong>Lithium disilicate is usually used for producing prosthetic crowns to be cemented on teeth or implant abutments. On the contrary, its use for producing implant abutment is not reported. This report describes the use of monolithic lithium disilicate to realize implant abutment and crown.</span></p> <p class="p1"><span class="s1"><strong>Case report </strong>A 60-year-old male patient required dental implant restoration for replacing the upper right central incisor. A lithium disilicate abutment and crown were realized by pressing. </span></p> <p class="p1"><span class="s1"><strong>Conlusion </strong>Lithium disilicate may be a valid alternative to zirconia for producing implant abutments in the esthetic area.</span></p> 2019-07-18T09:57:56+02:00 ##submission.copyrightStatement## https://journalofosseointegration.eu/index.php/jo/article/view/269 Effects of bioactive additions on the physical properties of glass polyalkenoate cement 2019-07-03T08:02:45+02:00 Abubaker Qutieshat asqutishat@just.edu.jo Abdurahman Salem dr.abdurahman.salem@gmail.com <p class="p1"><span class="s1"><strong>Aim </strong>Conventional glass ionomer cements are clinically attractive materials and have unique properties that make them useful dental restorative materials. The glass ionomer cements however are slightly brittle materials though they deform a little under load. They display high compressive strengths but slightly weak flexural strengths. Collagen type I and RGD peptides (Arg-Gly-Asp) are the most effective and widely used bioactive molecules to promote cell adhesion on a synthetic surface. This study investigates the effect of chairside addition of bioactive molecules (Collagen type I and RGD) into glass polyalkenoate cement on improving the physical properties. </span></p> <p class="p1"><span class="s1"><strong>Materials and methods</strong> Mechanical properties of the glass polyalkenoate cement (ChemFil Superior, Dentsply De Trey, Konstanz, Germany) were investigated both at baseline and after incorporating bioactive additions made at the time of mixing the material. The properties that are of potential significance for clinical durability were determined namely; compressive strength, diametral compressive strength, three-point flexural strength, diametral compressive fatigue limit, and biaxial flexural strength. Results: Additions of Type I Collagen and RGD to ChemFil Superior improved all physical properties measured except shear bond strength where no detriment was observed.</span></p> <p class="p1"><span class="s1"><strong>Conclusion</strong> Chairside additions of bioactive molecules to conventional glass ionomer restorations have potential clinical applications and represent a new paradigm in dentistry that can be utilized to improve biocompatibility, mechanical properties, and therefore, clinical durability. Improving the mechanical strength of glass ionomer restorations by optimized reinforcement strategy requires further investigation. Clinical significance: the methodology of mixing conventional glass ionomer with bioactive molecules for superior biocompatibility and reinforcement, developed in the present study, should be applicable to chairside dental procedures. The increase in physical properties of the glass polyalkenoate, achieved in the present study, may help extend its dental applications to the restoration of stress-bearing cavities.</span></p> 2019-07-02T09:55:25+02:00 ##submission.copyrightStatement## https://journalofosseointegration.eu/index.php/jo/article/view/256 Feline dental implants: new paradigm shift in maxillary alveolar osteitis treatment planning with osseodensification 2019-07-01T14:32:27+02:00 Rocco E Mele eastpointpet@gmail.com Gregori Michael Kurtzman drimplants@aol.com <p class="p1"><span class="s1"><strong>Background </strong></span>Felines are obligate carnivores and use their teeth for prehending as well as tearing and dissecting their food. Mastication is the first step of digestion, aiding in the lubrication of the food and the formation of a bolus. Mastication also increases the surface area of the food to be initially digested by salivary enzymes before being more easily swallowed. The teeth are specialized structures which play an important role in mastication, grooming, supporting the lips and the tongue, as well as being used as weapons for hunting and for self-defense. Although some mammals can still survive with few or no teeth at all, cats included, losing teeth can influence the types of foods that can be eaten, and will affect the ability to masticate and processing of the food prior to swallowing. Dental implants have become an option for replacement of lost canines in these animals. Although cats appear to manage well after a canine extraction, complications such as lip entrapment can occur, especially after maxillary canine tooth extraction.</p> <p class="p1">Even cats with a complicated crown fracture of the maxillary canine tooth that have had root canal therapy to preserve the tooth, can still suffer from lip entrapment. This can lead to painful lip ulcers and the need for further dental treatment. Today, canine tooth replacement with a dental implant/crown is a predictable option that can be offered to clients who would like to replace a lost canine tooth.</p> <p class="p1"><span class="s1"><strong>Case report<span class="Apple-converted-space">&nbsp; </span></strong></span>Two long term cases and follow up of lost maxillary canines caused by alveolar osteitis and replacement by dental implants, to restore normal function in feline subjects are reported.</p> <p class="p1"><span class="s1"><strong>Conclusion </strong></span>Dental implants proved to be a viable long-term treatment option in the 2 cats described.Immediate implant placement at the time of extraction helps to maintain the surrounding bone structures and prevent collapse of the labial buccal plate. So far, the authors have placed 30 implants in 15 feline subjects up to a 3-year follow-up and no integration failures have been observed to date.</p> 2019-07-01T14:21:01+02:00 ##submission.copyrightStatement## https://journalofosseointegration.eu/index.php/jo/article/view/274 The mechanical complications of platform switching connection on implant supported restorations: 2019-06-28T10:20:27+02:00 Aya Ahmed Salama aassalama@hotmail.com H.
