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 Obesity and dental implant treatment: a review <p><strong>Aim</strong> Success of dental implants depends mainly on osseointegration between bone and titanium surface. Since osseointegration relies on balanced bone turnover, it can be assumed that any conditions that interfere with homeostasis of bone modelling/remodeling might be detrimental to survival of dental implants. Obesity has become a serious public health problem, and has been shown to be closely linked to a wide array of pathophysiologic consequences, including insulin resistance or pre-diabetes. Obese-insulin resistance or pre-diabetic condition is characterized by hyperinsulinemia with euglycemia. The impacts of type 2 diabetes mellitus (T2DM) on the success of dental implants and the factors to improve osseointegration in diabetic condition have been thoroughly investigated. Much evidence demonstrated that T2DM impaired the bone healing around dental implants, possibly due to hyperglycemic condition. However, the effect of obese-insulin resistant condition or pre-diabetes on survival of dental implants has not been investigated. This review aims to summarize the current findings of effect of obesity toward bone health and osseointegration of dental implants.<br><strong>Conclusion </strong>The studies favor the relatively negative impact of diabetes on osseointegration, but more scientific studies are necessary.</p> Lyly Sam Siriporn Chattipakorn Pathawee Khongkhunthian ##submission.copyrightStatement## 2018-07-27 2018-07-27 95 102 10.23805/jo.2018.10.03.05
