Single versus splinted short implants at sinus augmented sites: A systematic review and meta-analysis.
OBJECTIVE
This review primarily evaluated the success, survival and failure rates of implants shorter than 10 mm restored with single-unit or splinted fixed dental prostheses in maxillary sinus augmented sites.
MATERIAL AND METHODS
Two reviewers independently performed the systematic search of electronic databases, including MEDLINE, EMBASE and CENTRAL, up to September 2019 with no language restriction. A supplemental hand search consisted of screening 13 journals. The inclusion criteria were: primary studies reporting implant, prosthetic and patient-reported outcome measures (PROMs) of extra-short and short implants placed in conjunction with sinus floor elevation in partially dentate patients, restored with single- and splinted-crowns for direct comparison, with a minimal 1-year follow-up. Weighted arithmetic mean (WAM) of the implant survival was performed according to the type of prosthesis. This was confirmed by using Review Manager software to perform meta-analysis.
RESULTS
Two observational studies reporting on 106 tapered, press-fit, sintered porous-surfaced implants with a length ranging from 5 mm to 9 mm were included in this systematic review. Of these, 20 and 86 implants were restored with single and splinted prostheses, respectively. The risk ratio (RR) was 1.16 (95% CI: .31-4.30, p = .58, I² = 0%) for individually restored implants failure when compared to splinted implants, indicating that short dental implants restored with single crowns could have a 16% higher possibility of failure if compared to implants with splinted crowns. The heterogeneity value was not statistically significative (p = .58). No statistical difference in the implant survival rate of the two types of analysed prostheses was observed after WAM (p= .923). The level of evidence for the included studies ranged from low (4) to fair (2B).
CONCLUSION
Similar clinical outcomes up to a 9-year follow-up were observed in single and splinted porous-surfaced implants shorter than 10 mm located in sites with sinus lift. However, the conclusion shall be interpreted with caution due to the level of evidence and limited number of included studies included in this systematic review
Leadership diversity in science : women editors of dental journals are underrepresented compared to women editors of medical journals
OBJECTIVES : Increasing numbers of women are entering dentistry and medicine and it is anticipated that global leadership positions represent this demographic. In this study, the proportion of women editors of prominent medical and dental journals was compared.
METHODS : A list of dental and medical journals, ranked by impact factor, were obtained through Web of Science Journal Citation Reports 2020. Chief and associate editors of these journals were identified as either a woman or a man.
RESULTS : Ninety one dental journals had 100 editors, 15 of whom were women. There were significantly less women chief editors than men (p < 0.0001) compared to the percentage expected (global proportion of women and men dental scientists [IADR] membership: 43.72% women). Of ninety one comparable medical journals ranked by impact factor, there were 103 chief editors, 41 of whom were women. There was no significant difference in the number of men and women chief editors for medical journals (p = 0.242). There were significantly fewer women chief editors for dental journals compared to medical journals (p < 0.0001). There was no significant difference between the mean impact factor for journals with women and men editors for dental (p = 0.556) or medical (p = 0.492) journals. For the 91 dental journals, there were a total of 828 associate editors, of whom 638 were men and 190 were women and this difference was significant (p < 0.0001).
CONCLUSIONS : The results demonstrate that women in dental research have attained editor positions with less frequency than men indicating the presence of barriers to progress in scientific dental publishing.https://www.elsevier.com/locate/jdenthj2022Prosthodontic
Innovative Trends in Implant Dentistry Training and Education: A Narrative Review
The field of implant dentistry education is rapidly evolving as new technologies permit innovative methods to teach the fundamentals of implant dentistry. Literature from the fields of active learning, blended learning, augmented reality, artificial intelligence, haptics, and mixed reality were reviewed and combined with the experience and opinions of expert authors. Both positive and negative aspects of the learning methods are presented. The fundamental objectives of teaching and learning remain unchanged, yet the opportunities to reach larger audiences and integrate their learning into active experiences are evolving due to the introduction of new teaching and learning methodologies. The ability to reach a global audience has never been more apparent. Nevertheless, as much as new technology can be alluring, each new method comes with unique limitations

Leadership diversity in prosthodontics: Number and percentage of women chief editors of journals publishing prosthodontic science
STATEMENT OF PROBLEM : The number and percentage of women chief editors of journals publishing prosthodontic science is unknown.
PURPOSE : The purpose of this observational study was to calculate and compare the number and percentage of women and men chief editors of journals publishing prosthodontic science.
MATERIAL AND METHODS : A list of the dental journals, as ranked by impact factor, was obtained through the Web of Science Journal Citation Reports 2020 using the category “Dentistry, Oral Surgery, and Medicine.” Of the 91 journals listed in the Journal Citation Report, 28 published scientific findings related to prosthodontics. The chief editors of these 28 journals were identified, and their gender was recorded. The percentage of women and men chief editors was compared with the percentage of women and men members of the International Association of Dental Research (IADR) and the International College of Prosthodontists (ICP) by using the binomial test (α=.05).
RESULTS : Of the 28 included journals, a total of 32 chief editors were identified; of whom, 4 (12.5%) were women and 28 (87.5%) were men. There were 7886 members of the IADR who reported their gender; of whom, 3448 (43.7%) were women. There were 906 members of the ICP; of whom, 248 (27.5%) were women. Compared with the percentage of women and men members of the IADR and ICP, women chief editors were significantly underrepresented (P<.001 and P=.039, respectively).
CONCLUSIONS : The number and percentage of women chief editors of journals publishing prosthodontic science is of concern.http://www.journals.elsevier.com/journal-of-prosthetic-dentistry2023-10-11hj2023Prosthodontic
In Vitro Analysis of the Effects of Two Air-Abrasive Prophylaxis Systems and Inlet Air Pressure on the Surface of Titanium Abutment Cylinders
: The purpose of this study was to investigate the effects of two air-abrasive prophylaxis systems and the effect of inlet air pressure on the surface of BrĂ…nemark titanium abutment cylinders. Materials and Methods : Single abutment cylinders were treated with either the Prophy-Jet system (sodium bicarbonate abrasive) (Dentsply International, York, PA) or the Microprophy system (aluminum oxide abrasive) (Danville Engineering Co, Danville, CA) for 60 seconds at an inlet air pressure of 60 psi or 90 psi. The effects on the surface of each abutment cylinder were visually inspected by scanning electron microscopy. Results : A comparison of abutment cylinder surfaces after treatment showed that the Prophy Jet system removed machining marks to a greater degree than the Microprophy system. Sodium bicarbonate particles from the Prophy-Jet system were significantly larger than the aluminum oxide particles used with the Microprophy system, potentially accounting for the difference in abrasivity. In addition, inlet air pressure of 60 psi caused removal of machining marks to a greater degree than an inlet air pressure of 90 psi. The principle of phase separation may account for the lower inlet air pressure causing more removal of machining marks than the higher inlet air pressure. Conclusions : Under the experimental conditions tested, neither of the two systems tested seemed to cause significant abrasion of the surface of titanium abutment cylinders.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73524/1/j.1532-849X.1994.tb00136.x.pd
