The aim of the study was to compare insertion torque and implant stability quotient (ISQ) obtained at the time of implant placement, as predictors of osseointegration.<br><strong>Methods </strong>There were 31 implants evaluated in the maxilla and 29 in the mandible. A “High Torque Indicating Ratchet Wrench” was used for the measurement of insertion torque and a “Osstell Mentor®” to register the ISQ value at the end of each surgery. At 6 weeks counter-torque was performed on each implant using a “Low Torque Indicating Ratchet Wrench” applying 20 to 32 Ncm. Successful osseointegration was appropriately obtained with torque insertion of 35 or more and an ISQ of 60 or more without mobility, as well as torque insertion less than 35 and an ISQ less than 60 with mobility. The results, contrary to those described above, were considered to be failure.<span class="Apple-converted-space">&nbsp; </span>The use of ROC (Receiver Operating Characteristic) curves establishes differences between the two methods. Contingency tables and Kappa statistics were used to analyze the coincidence results between methods. Insertion torque was used as the Gold Standard. The significance level used is α≤0.05.<br><strong>Results </strong>In the ROC curve analysis, the area of value was 0.611 (p&gt; 0.05). The Kappa statistic value was 0.208 (p&gt; 0.05) and there are no discrepancies between success and failure between the two methods compared.<br><strong>Conclusion </strong>Both methods tend to have the same results in relation to the studied variables.</p> Osvaldo Gahona Gutiérrez Xenia Granic Marinov Cristina Antunez Chelmes Stefan Domancic Alucema Víctor Patricio Díaz Narváez Robert Utsman Abarca ##submission.copyrightStatement## 2018-07-27 2018-07-27 103 107 10.23805/jo.2018.10.03.06 Critical review of literature on the use of short implants <p><strong>Aim </strong>The aims of this review were to verify the validity of short implants as a treatment option in patients with partial or total edentulism, having more or less atrophic jawbones.<br><strong>Methods </strong>A systematic review of randomized controlled trials (RCT) was conducted, involving also prospective and retrospective studies published in<span class="Apple-converted-space">&nbsp; </span>English language between January 2005 and December 2015. The PubMed and Scopus databases were electronically analyzed. Titles and abstracts were selected, and full texts were evaluated. The data were organized in tables and then presented as a narrative analysis.<br><strong>Results </strong>The electronic search provided 891 publications, 50 articles were retrieved in full text and only 11 were included in the review. Although the performance of the implants was evaluated through different success and survival criteria, short implants have shown to have a similar performance to longer implants.<br><strong>Conclusions </strong>Short implants could be considered as a treatment option comparable to traditional lenght implant. However, other studies must be conducted to assess uniform criteria to state the quality of treatment.</p> Elisa Ciarmatori Alfredo Passaretti Giovanna Miracolo Andrea Cicconetti ##submission.copyrightStatement## 2018-07-27 2018-07-27 87 94 10.23805/jo.2018.10.03.04 An unconventional approach for retrieval of fractured prosthetic screw: A case report <p><strong>Background</strong> Implant-supported restorations can fail biologically or mechanically. Mechanical failures include crown fracture, framework fracture, screw loosening, and screw fracture. Fracture of the implant abutment screw can be a serious problem leading to implant failure. Unavailability of universal standard screw retrieval kit in market makes it difficult to retrieve the fractured screw of various implant systems.<br><strong>Conclusion</strong> This clinical report describes the management of an implant prosthetic screw fracture using an unconventional technique and simple armamentarium available in regular clinic setup.</p> Aniruddha Joshi Vishwajeet T Kale Girish Suragimath Sameer Anil Zope ##submission.copyrightStatement## 2018-07-27 2018-07-27 75 78 10.23805/jo.2018.10.03.02 Impact of single implant versus two-implant mandibular retained overdentures on retention and success rate in totally edentulous patients. A Randomized Controlled Clinical Trial <p><strong>Aim </strong>Purpose of this RCT was to evaluate the denture retention and success rate of totally edentulous patients in single median versus two inter-foraminal implant-supported mandibular over-dentures on.<br><strong>Material and methods </strong>Twenty-four totally edentulous patients were selected in this trial. The eligible patients were allocated randomly into two equivalent groups of 12 participants each. A single-implant (G I) or two inter-foraminal implants (GII) were located in the mandible. Three months later, pick up of the locator attachment wa performed to<span class="Apple-converted-space">&nbsp; </span>all<span class="Apple-converted-space">&nbsp; </span>implants and<span class="Apple-converted-space">&nbsp; </span>denture bases. Assessments of denture retention and success rate of implants were measured at the three, six, and twelve month's follow-up assessments. The study consists of twenty-four totally edentulous patients (14 males and 9 females) with age range of 59.6 years. Thirty six implants were inserted (12 in single-implant and 24 in the two inter-foraminal implants). All patients accomplished the twelve months period of follow-up.<br><strong>Results</strong> Regarding<span class="Apple-converted-space">&nbsp; </span>denture retention, the two inter-foraminal implant group (GII) showed statistically significant differences compared to the single-implant group (GI). Concerning success criteria of implants the results revealed insignificant differences between patients in<span class="Apple-converted-space">&nbsp; </span>both groups.<br><strong>Conclusion</strong> Single-implant mandibular over-dentures may be recommended as an alternate treatment option for the management of edentulous patients in populations with low economic status.</p> Ali Abdulghani AlSourori Marwa Hassan Mostafa Amal Fathy Kaddah Ahmed Emad Fayyad Ahmed Zakaria Al Adl Mostafa Saad Swedan ##submission.copyrightStatement## 2018-07-27 2018-07-27 79 86 10.23805/jo.2018.10.03.03
