Review
OBJECTIVE
To report an alternative clinical and laboratory protocol for same-day implant fixed full-arch provisional rehabilitation that may overcome limitations associated with traditional immediate provisional denture conversion rehabilitation protocols.
CLINICAL CONSIDERATIONS
The traditional denture conversion fabrication method of an immediate full-arch fixed provisional involves the conversion of a complete denture into a provisional fixed implant-support prosthesis. The conversion technique has several shortcomings which compromise structural integrity, longevity, ease of modification, and the need for a silicone impression.
CONCLUSIONS
The "Same day" implant bridge (SDIB) concept provides clinical and laboratory advantages which overcome the limitations of the traditional denture conversion technique. This article reviews the rationale, clinical stages, and conventional fabrication sequence of the SDIB concept.
CLINICAL SIGNIFICANCE
Compared to the traditional denture conversion method for immediate implant bridge fabrication, the SDIB technique offers the following advantages for implant-supported fixed rehabilitation: rapid fabrication, improved structural integrity and rigidity, elimination of all silicone impressions, ease of modification to promote comfort, function and adaptability, and favorable esthetics.

Review
BACKGROUND
All disciplines of dentistry require that clinicians assess the articulation of the teeth/prosthesis with respect to simultaneous contacts, bite force and timing.
AIMS
This article intends to describe the advantages and limitations of the data acquired when using a computerized occlusal analysis as a dynamic occlusal indicator.
METHODOLOGY
A search of the literature was completed (Medline, PubMed) using the keywords occlusion, occlusal registration, computerized occlusal analysis and T-Scan for dental.
RESULTS
According to the evidence available, the computerized occlusal analysis system is the only occlusal indicator that demonstrates the ability to provide quantifiable force and time variance in a real-time window from the initial tooth contact into maximum intercuspation.
CONCLUSION
The reported advantages to accurately indicate occlusal contacts make the computerized occlusal analysis system a better occlusal indicator when compared with other non-digital convention indicator materials available.

BACKGROUND
Under dentistry's social contract with the public, dental professionals have a social responsibility to address the oral health needs of the population at large. However, dental education places little emphasis on such moral commitments. By ascertaining dental students' stance regarding these notions, we may be able to inform changes in dental education. This paper thus explores dental students' comprehension of dentistry's social contract using the concepts of moral inclusion, moral community and empathy.
METHODS
A cross-sectional online survey collected information from undergraduate dental students at the Faculty of Dentistry, University of Toronto (N = 430). Moral inclusion was assessed through the breadth of students' moral community by computing a "moral inclusion score" (MIS) from Likert scale responses to statements that asked students about their duty of care for different population groups, wherein a higher MIS indicated a broader moral community and in turn greater moral inclusiveness. Empathy was assessed using Likert scale responses to statements that gauged the extent to which students understood the effect of social determinants on people's health. Association of the MIS with environmental, institutional and student-related factors was also investigated using non-parametric tests and linear regression.
RESULTS
The survey yielded a response rate of 51.4% (n = 221). Overall, students in this sample were morally inclusive and displayed empathy. Regression results showed that the MIS was most strongly associated with choosing a small town/rural area as a future practice location (β = 4.76, 95% CI: 0.52, 9.01) and viewing patients as consumers (β = -3.71, 95%CI: -7.13, -0.29).
CONCLUSION
Students in this sample made morally inclusive choices, which implied that they had a basic understanding of the obligations under dentistry's social contract. Improving knowledge and experience with regards to addressing the social and economic determinants of oral health and access to oral health care may positively influence students' perceptions of their professional duties under the social contract.

The Journal of Prosthetic Dentistry Feb 2020The performance of a recently introduced overdenture attachment system after cyclic dislodgement is not known.
STATEMENT OF PROBLEM
The performance of a recently introduced overdenture attachment system after cyclic dislodgement is not known.
PURPOSE
The purpose of this in vitro study was to compare a conventional attachment system and a recently introduced attachment system for their dislodgement forces before and after cyclic dislodgement.
MATERIAL AND METHODS
Three acrylic resin models were fabricated with 2 implant analogs (4.1 mm; Zimmer Dental) in different angulations; parallel in the first, divergent by 30 degrees in the second, and divergent by 60 degrees in the third model. Six acrylic resin blocks containing 2 metal housings of 2 different LOCATOR attachments (LOCATOR Legacy [LL], R-Tx, n=3; Zest Dental Solutions) were also fabricated. LOCATOR abutment pairs (LL and R-Tx) were placed onto the analogs. Seven specimens for LL and R-Tx with pink attachments were tested for dislodgement forces, and the values were recorded before and after 1440 times (simulated 1-year use) of cyclic dislodgement using an occlusal loading simulator machine. A 3-way ANOVA was used for dislodgement force comparison before and after cyclic dislodgement for different angulations and for 2 different LOCATOR attachments. Any significant differences were identified with the Tukey HSD test (α=.05). The percentage decrease in the dislodgement force was also calculated.
RESULTS
A significant 3-way interaction was found for the LOCATOR type, implant angle, and time (P<.001). LOCATOR type made a difference for only parallel and 60 degree-divergent implants before cyclic dislodgement (P≤.022). After cyclic dislodgement, a significant effect of the LOCATOR type on dislodgement force was found for only parallel implants (P=.034). In both LOCATOR systems, the dislodgement force was different (P<.001) among different implant angulations, except for parallel to 30-degree comparison, before and after cyclic dislodgement. For both LL and R-Tx, significant differences (P≤.022) were found between before and after cyclic dislodgement for all angulations except LL in parallel (P=.214).
CONCLUSIONS
When implants were parallel, initially, the dislodgement force of R-Tx was higher than that of LL; however, the forces were similar after cyclic dislodgement. When implants were divergent by 30 degrees, there were no differences between the dislodgement forces of the LOCATOR systems before and after cyclic dislodgement. When implants were divergent by 60 degrees, initially, the dislodgement force of LL was higher than that of R-Tx; however, the forces were similar after cyclic dislodgement. Before and after cyclic dislodgement, in each system, dislodgement forces were greater when implants were divergent by 60 degrees than when parallel and 30 degrees. After cyclic dislodgement, dislodgement forces decreased for both systems, except for LL when the implants were parallel.

Review
This study analyzes the characteristics of the top-100 most cited articles published in international dental journals with at least one coauthor affiliated to Brazil. A search in Scopus database for articles published between 1996 and 2017 was carried out in the 178 journals belonging to the category "Dentistry" identified in SCImago Journals & Country Rank. From the top-100 most cited articles, variables related to the journal, article, and authors were collected. Annual citation averages (ACA) and relative citation ratios (RCR) were calculated. Data were analyzed descriptively. There were 75 original reports and 25 reviews in the sample. The number of citations ranged between 124 and 657 (mean=202, median=168). The papers were published in 31 different journals (46% in only four journals), none based in Brazil. The most frequent subjects (61%) were Dental Materials, Endodontics, and Periodontology, which accounted for 63.6% of the total citations. The subject with the highest ACA was Oral and Maxillofacial Surgery and the subject with the highest RCR was Oral Radiology. Only 12 articles were cited more than 300 times. International collaboration was present in 61 articles and funding was reported in 49 articles. The first author was from Brazil in 70% and corresponding author in 55% of the papers. Southeast (83%) and South (20%) were the regions of Brazil with most presence of coauthors. This top-100 list is presented to provide an overview of the most cited articles and aid in supporting further analyses regarding publication and citation behaviors of Brazilian dentistry.

Review
Optical technology has provided a paradigm shift in implant dentistry. However, there is little information about the use of optical technology in implant dentistry, since this technology is relatively new and has been evolving under the current conditions. In the present narrative literature review, the effects of intraoral scanners (IOSs) use on accuracy and the operating time, as well as safety and patient perception, in implant dentistry were evaluated from the clinical perspective. The accuracy of digital scans with IOSs was comparable to the conventional impression techniques for single or partial prostheses, and the digital scans with IOSs are time efficient when taking impressions for single- or double-abutments. However, the accuracy and time efficiency are decreased for multiple implant scans or large-area scans with IOSs use. Patient satisfaction with and preference for IOSs scans are generally superior to those with conventional impression procedures.

Review
The All-on-4 treatment concept offers advantages to patients seeking full-arch immediate function, including reduced treatment time and costs, improved esthetics, and high patient satisfaction. The biomechanical basis and clinical success of the All-on-4 concept have been validated by numerous scientific and clinical studies. Nevertheless, relatively few clinicians have successfully implemented this extraordinary service for their patients. This article introduces specific planning and treatment protocols advanced by the authors that are intended to: reduce surgical and restorative chairtime; circumvent surgical site disruption; improve the durability and esthetics of the provisional restoration; optimize patient comfort and convenience; and increase clinical implementation compared to first-generation protocols.
